12 patients with 12 abscesses |
To determine the clinical effectiveness of CT-guided injection of 0.9% saline solution into the retroperitoneal space to create access routes for imaging-guided percutaneous abscess drainage. |
Over a 10-year period, 23 patients (20 men; average age, 54 y; range, 34–77 y) with 24 mediastinal abscesses underwent 25 CT-guided drainage procedures. Abscess etiologies included esophageal leak after esophagectomy (n = 6), perforated esophageal cancer (n =4), Nissen fundoplication (n = 3), emetogenic esophageal rupture (n =3), infectious (n =2), cardiac surgery (n =1), iatrogenic (n =1), gastric strangulation (n =1), Whipple procedure (n = 1), and thoracotomy for lung cancer (n =1). Drainages were performed with tandem trocar (n =14) or Seldinger (n =11) technique. A total of 25 catheters were used: 8.5 F (n = 9), 10 F (n =8), 12 F (n =6), 14 F (n =1), and 16 F (n =1). The mean time of catheter drainage was 13.6 days. Technical success was achieved in all 25 attempts (100%). Twenty-two of the 23 patients had complete resolution of the abscess without the need for surgical debridement, for a clinical success rate of 95.6%. One patient underwent technically and clinically successful abscess drainage but required surgical exploration for repair of an anastomotic leak after esophagogastrectomy. There was one complication. One patient had inadvertent placement of a catheter within a pulmonary vein. The catheter was removed after 24 hours without hemodynamic consequences. |

30 patients |
To evaluate the safety and efficacy of transhepatic drainage of inaccessible postoperative intraabdominal abscesses under sonographic and fluoroscopic guidance. |
The technical and clinical success rates were 100% and 97%. The procedures were performed with 8-, 10-, and 12-French locking pigtail catheters. The catheters were in place for a mean duration of 75 days if a fistula was present and 15 days in the absence of fistula. Major complications were not detected during treatment. The rate of minor complications (catheter dislodgement, obstruction, kinking) was 20%. Most of the complications were managed by exchange, revision, or increase in size of the catheter. When use of an 8-French catheter was compared separately with use of 10- and 12-French catheters, the rate of minor complications was found to be significantly higher for the 8-French group (p < 0.05). Five abscesses had fistulous communication with the pancreatic duct, jejunum, and biliary system. The mean duration of catheter use was increased by the presence of a fistula (p < 0.05). When single-microbe, polymicrobial, and culture-negative abscesses were compared, the difference between groups with respect to mean duration of catheter use was not statistically significant (p > 0.05). Mean duration also did not differ significantly between patients with an abscess volume greater than and those with an abscess volume less than 100 mL (p > 0.05). |

12 consecutive patients |
To evaluate the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. |
For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6–9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12–41 min). All abscesses were drained. They shrank immediately after catheter placement. |

To examine the efficacy of parenteral antibiotic therapy in treating children with perforated appendicitis and intra-abdominal infection (IAI), determine the impact of percutaneous drainage (PD) in augmenting clinical resolution of IAI and characterize IAI bacteriology. |
All patients received broad spectrum parenteral antibiotic therapy. One-third were hospitalized for >2 weeks. IAI was identified on admission in 60% compared with developing during hospitalization in 40% of cases. Before performing percutaneous drainage (PD), the mean duration of antibiotic therapy in those who developed intra-abdominal infection (IAI) during hospitalization was 6 days. IAI cultures yielded 127 bacterial isolates; polymicrobial infection occurred in 65% of cases. Only 7% of aspirates were sterile. The most common pathogens were Escherichia coli (82%), of which 5 isolates exhibited extended-spectrum ß-lactamase production, and streptococci (40%). At the time of PD, 60% were febrile (mean duration of in-hospital fever, 7.5 days); 67% defervesced within 24 hours after the procedure. Posthospitalization abdominal complications (recurrent IAI or appendicitis) occurred in one-third of patients. |

The purpose of the study was to evaluate the efficacy of percutaneous drainage of intraperitoneal abscesses with attention to recurrence and failure rates. |
Nine abscesses were drained by simple aspiration; catheter drainage either by Seldinger or trocar technique was used in the remaining 291 abscesses with 6F to 14 F catheters. Initial cure and failure rates were 68% (203/300) and 12% (36/300), respectively. Sixty-one abscesses (20%) were either palliated or temporized. The recurrence rate was 4% (12/300) and nine of them were cured by recatheterization, whereas three of them were treated by medication or surgery. The overall success and failure rates were 91% (273/300) and 9% (27/300), respectively, with temporized, palliated, and recatheterized recurred abscesses. The 30-day mortality rate was 3.1% (8/255). The mean duration of catheterization was 13 days. |

To refine the judgement leading to a recommendation for PCD by determining the characteristics of intra-abdominal abscess that result in resolution of the infection without laparotomy. |
The study included 96 patients (59% men; mean +/- SD age, 48 +/- 17 years; mean +/- SD Acute Physiology and Chronic Health Evaluation II score, 7.4 +/- 4.9). Postoperative abscess was present in 53% of patients. Isolated microorganisms included Bacteroides species (17%), Escherichia coli (17%), Streptococcus species (14%), Enterococcus species (10%), and fungi (11%). Single abscesses were present in 83% of patients. Computed tomographic guidance was used for drainage in 80% of patients, and ultrasound was used in 20%. The duration of abscess drainage was less than 14 days in 64%. Complete resolution of the infection with a single treatment of PCD was achieved in 67 patients (70%), and with a second attempt in 12 (12%). Thirty-three patients (34%) had PCD for the resolution of intra-abdominal sepsis prior to an elective, definitive procedure. Open drainage as a result of PCD failure was required in 15 (16%) and was more likely in patients with yeast (P<.001) or a pancreatic process (P =.02). Postoperative abscess (P =.04) was an independent predictor of successful outcome. |

To describe our experience with percutaneous drainage of abcesses occurring after abdominal and pelvic surgery. |
One hundred and twenty-one peritoneal, retroperitoneal and pelvic abscesses were treated percutaneously using CT or US guidance. The lesions developed after abdominal surgery. Sixty-three abscesses (52%) were situated in the peritoneal cavity, 31 (26%) in the retroperitoneal cavity and 27 (22%) in the pelvis. A definitive treatment was obtained in 74% of peritoneal abscesses, 67% of retroperitoneal abscesses and 82% of pelvic abscesses. Failure most commonly occurred with multiloculated lesions or lesions associated with fistulous communication. There was a low rate of complication (1%). |

To examine the clinical characteristics and outcomes of patients undergoing percutaneous drainage of intra-abdominal abscesses arising after elective colorectal procedures. |
Percutaneous CT-guided abscess drainage is an effective method for treating intra-abdominal abscess following elective colorectal surgery. The primary success was 65% after the first and 85% after a second drainage. This technique should be considered as the treatment of choice in patients with localized intra-abdominal abscess without signs of generalized peritonitis. |

To review the outcomes of patients who underwent percutaneous drainage of colonic diverticular abscess without subsequent operative intervention. |
Two hundred eighteen patients underwent percutaneous drainage of colonic diverticular abscesses. Thirty-two patients (15%) did not undergo subsequent colonic resection. Abscess location was pelvic (n = 9) and paracolic (n = 23), the mean abscess size was 4.2 cm, and the median duration of percutaneous drainage was 20 days. The comorbidities of this group of patients included severe cardiac disease (n = 16), immunodeficiency (n = 7), and severe pulmonary disease (n = 6). Freedom from recurrence at 7.4 years was 0.58 (95% CI 0.42-0.73). All recurrences were managed nonoperatively. Recurrence was significantly associated with an abscess size larger than 5 cm. Colectomy-free survival at 7.4 years was 0.17 (95% CI 0.13-0.21). |

To determine the risk of recurrent appendicitis following initial nonoperative treatment for appendicitis, and evaluate factors associated with recurrence. |
The type of appendicitis was abscess in 7% of patients, peritonitis in 18%, and no peritonitis or abscess in 75%. Emergency appendectomy was performed in 31,926 (97%) patients. Nonoperative treatment was used initially in 1012 patients (3%). Of these, 148 (15%) had an IA and the remaining 864 (85%) did not. Thirty-nine patients (5%) recurred after a median follow-up of 4 years. Using Cox regression, sex had a slight influence on recurrent appendicitis (hazard ratio males vs females = 0.52, 95% CI, 0.27-0.99, P = .05). Age, Charlson comorbidity index, type of appendicitis, or percutaneous abscess drainage had no influence on recurrence. Median length of hospital stay was 4 days for the admission for recurrent appendicitis compared with 6 days for the IA admission (P = .006). |

Meta-analysis |
17 studies |
To compare the outcomes of patients presenting with complicated appendicitis who underwent CT with or without interval appendectomy (IA) versus patients who underwent acute appendectomy (AA). |
Seventeen studies (16 nonrandomized retrospective and 1 nonrandomized prospective) reported on 1,572 patients: 847 patients received conservative treatment and 725 had acute appendectomy. Conservative treatment was associated with significantly less overall complications, wound infections, abdominal/pelvic abscesses, ileus/bowel obstructions, and reoperations. No significant difference was found in the duration of first hospitalization, the overall duration of hospital stay, and the duration of intravenous antibiotics. Overall complications remained significantly less in the conservative treatment group during sensitivity analysis of studies including only pediatric patients, high-quality studies, more recent studies, and studies with a larger group of patients. |

To study the therapeutic effectiveness of percutaneous drainage with antibiotics and the need for an interval appendectomy for treating appendiceal abscess in children with a research-oriented dataset released by the Bureau of National Health Insurance in Taiwan through the Collaboration Center for Health Information Application (CCHIA). |
Totally, 6190 children had an appendiceal abscess, an 1225 patients received non-operative treatment. Of 1225 patients, 150 patients received treatment with percutaneous drainage and antibiotics, 78 had recurrent appendicitis, 185 went on to receive an interval appendectomy, and 10 had postoperative complications after the interval appendectomy. We found that patients treated with percutaneous drainage and antibiotics had a significantly lower rate of recurrent appendicitis (p?<?0.05), a significantly smaller chance of receiving an interval appendectomy (p?<?0.05), and significantly fewer postoperative complications after the interval appendectomy (p?<?0.05) than those without percutaneous drainage treatment. Older children (13?~?18 years) patients were found to have a significantly smaller need to receive an interval appendectomy than those who were?=?6 years of age (odd ratio (OR)?=?2.071, 95 % confidence interval (CI)?=?1.34-3.19, p?<?0.01), and those who were 7?~?12 years old (OR?=?1.662, 95 % CI?=?1.15-2.41, p?<?0.01). In addition, those treated with percutaneous drainage were significantly less indicated to receive an interval appendectomy later (OR?=?2.249, 95 % CI?=?1.19?~?4.26, p?<?0.05). In addition, those with recurrent appendicitis had a significantly increased incidence of receiving an interval appendectomy later (OR?=?3.231, 95 % CI?=?1.95?~?5.35, p?<?0.001). |

Review/Other-Dx |
2,209 patients |
To analyze risk factors for failed management of appendiceal abscess with percutaneous drain placement. |
A total of 2,209 patients with appendiceal abscesses received drains; 561 patients (25.4%) failed conservative management and underwent operative intervention. On univariable analysis, patients who failed conservative management were younger, more likely to be Hispanic, have more inpatient diagnoses, and to have undergone drainage earlier in the hospital course. Multivariable regression demonstrated that the number of diagnoses, female sex, and Hispanic race were predictive of failure of drainage alone. Older age, West and Midwest census regions, and later drain placement were predictive of successful treatment with drainage alone. Failure was associated with more charges and longer hospital stay but not with a higher mortality rate. |

Nineteen patients (11 male) were identified. Sixteen underwent ileocolectomy with primary anastomosis while only three patients required an upstream diverting ileostomy in addition to resection due to incompletely drained abscesses. The mean length of hospital stay was 13.9 +/- 0.6 days including 6.4 +/- 0.4 postoperative days. Four patients had post-op complications that did not require surgery (two self-limited anastomotic bleeds, one wound infection, and one pelvic abscess treated with a percutaneous drain). One patient needed reoperation for a small bowel obstruction. |

To determine technical success with PAD in patients with Crohn’s disease during 14 years. |
The technical success rate was 96%. In 16 (50%) of 32 patients, the need for surgery in the short term was avoided, and surgery was more likely to be avoided in patients with postoperative abscesses than in those with spontaneous abscesses (P =.07). At long-term follow-up, short-term avoidance of surgery did not significantly increase the likelihood of need for surgery in the long term, which occurred in nine of 16 short-term successes versus five of 15 short-term failures (P =.55). Recurrent abscesses occurred in seven (22%) patients, a rate comparable to that with surgical abscess drainage; four (44%) of nine cases of re-drainage were successful. |

To examine the effect of either surgical or percutaneous drainage therapy on time to resolution of abdominal and pelvic abscesses in Crohn’s disease. |
Time to resolution of abdominal or pelvic abscesses in Crohn’s disease is similar with percutaneous drainage and surgery. One-third of patients treated with percutaneous drainage required surgery within 1 year. Earlier intervention for abdominal and pelvic abscesses is associated with shorter time to resolution. |

To compare the incidence of severe postoperative intra-abdominal septic complications in patients undergoing intestinal resections with and without preoperative PAD before definitive surgery. The incidence of postoperative intra-abdominal septic complications in patients with (group I) and without (group II) preoperative PAD (Fisher's exact test) were compared. |
PAD was performed in 12/25 patients (48%), with an average of 37 days before surgery (range, 6-83 days). The overall rate of postoperative intra-abdominal septic complications was 48% (12/25 patients). In group I, postoperative intra-abdominal septic complications occurred in 3/12 patients (25%). In group II, postoperative intra-abdominal septic complications were assessed in 9/13 patients (69%). The differences between these two groups were considered to be statistically significant (P=0.04). PAD of intra-abdominal abscesses before surgery could significantly reduce the occurrence of severe postoperative intra-abdominal septic complications in patients with Crohn’s disease. |

Seventy patients with Crohn's disease-related abdominopelvic abscesses were identified, 38 (54%) of whom underwent drainage before surgery. Percutaneous drainage was technically successful in 92% of patients and clinically successful in 74% of patients. No differences in rate of septic complications (p = 0.14) or need for stoma creation (p = 0.78) were found. Patients who underwent percutaneous drainage had greater overall hospital lengths of stay (mean 15.8 versus 12.2 days, p = 0.007); 8.6% of patients had long-term postponement of surgery after percutaneous drainage. |

To evaluate CT for the presence of an abscess, its location, maximum diameter, and feasibility of PAD and to determine whether abscess size can be used as a discriminating factor to guide management of patients with diverticular abscesses. |
Patients with abscesses <3 cm in size can be treated with antibiotics alone and, in some cases, as outpatients, and may not uniformly require surgery. This is also likely true for patients with abscesses 3-4 cm in size. Patients with abscesses =4 cm can be managed with CT-guided abscess drainage followed by referral for surgical treatment. |

Review/Other-Dx |
203 Children |
To identify whether early appendectomy, or nonoperative management followed by interval appendectomy has the lowest health care utilization and cost. |
A total of 203 children with perforated appendicitis were identified. After exclusion of immunosuppressed patients and outside hospital transfers, 94 patients were included in the study. Thirty-nine underwent early appendectomy and 55 initial nonoperative management; of these, 54 underwent elective interval appendectomy. Five of 55 patients (9%) failed initial nonoperative management and required earlier-than-planned appendectomy. Total cost over 2 y was significantly lower with early appendectomy than initial nonoperative management ($19,300 ± 14,300 versus $26,000 ± 17,500; P = 0.05). Early appendectomy resulted in fewer hospital admissions, clinic visits, invasive procedures, and imaging studies. |

Observational-Dx |
43 Patients |
To determine the incidence and results of repeated (secondary) percutaneous abscess drainage performed on recurrent abscesses after successful initial (primary) percutaneous abscess drainage. |
Forty-five abscesses in 43 patients required secondary percutaneous abscess drainage. Twenty-four of the 43 patients avoided surgery. Secondary percutaneous abscess drainage was successful in evacuating the abscess cavity in 39 (91%) of 43 patients. Duration of drainage and time until recurrence were not significant predictors for avoiding surgery. Mean duration of secondary percutaneous abscess drainage was significantly longer than mean duration of primary percutaneous abscess drainage, but duration of secondary percutaneous abscess drainage (25 vs 14 days, respectively; p = 0.007) did not differ significantly between patients who ultimately required surgery and those who did not (17 vs 11 days, respectively; p = 0.10). Time to recurrence ranged from 2 days to 1 year (mean, 51 days). |

2,224 patients |
To determine the frequency with which percutaneous abdominopelvic abscess drainage catheters must be replaced because of inadequate drainage, to assess the effect of percutaneous catheter exchange on clinical outcome, and to determine the predictors of clinical success after catheter exchange. |
Among the 3,027 percutaneous abscess drainage catheters placed, 82 were exchanged because of lack of improvement (imaging evidence of undrained fluid and persistent fever and leukocytosis), for an overall frequency of catheter exchange of 2.7% of abscesses in 3.7% of patients. The success rate of catheter replacement, defined as resolution of the fluid collection without open surgical drainage, was 76.8% (63/82). Prognostic factors favorably influencing the clinical success of catheter exchange included a larger number of drainage catheter sideholes, absence of a fistula, low residual abscess volume after initial catheter drainage, and low CT attenuation of abscess fluid. |

Review/Other-Dx |
51 Patients |
To analyze the efficacy of recombinant tissue plasminogen activator (r-TPA) injection in the evolution of percutaneous drainage of thick collections. |
A total of 53 percutaneous drainage procedures, with r-TPA injection, were performed in 51 patients. Abdominal and pelvic collections were the most common, being seen in 38 (73%) of the procedures; in 35 (66%), the etiology of the collection was attributed to postoperative complications. A total of 61 catheters were used in order to drain the 53 collections. Of those 61 catheters, 52 (85%) were large (12-16 Fr) and 9 (15%) were small (4-10 Fr). The mean r-TPA dose was 5.7 mg/collection per day, and the mean time from r-TPA injection to drain removal was 7.7 days. Percutaneous drainage in combination with r-TPA injection was successful in 96% of the cases. None of the patients showed coagulation changes during the study period. |

To retrospectively determine the effectiveness of and risk for hemorrhage with intrapleural adjunctive tPA administered via chest tubes placed with imaging guidance. |
57 (86%) of 66 patients underwent complete drainage with tPA without further surgical procedures. Primary effectiveness was seen in 52 (87%) of 60 patients and secondary effectiveness was seen in five (83%) of six. Intrapleural tPA is effective in improving drainage of loculated effusions not drained with catheters alone; prophylactic systemic anticoagulation does not increase bleeding risk with intrapleural tPA, but therapeutic anticoagulation is associated with a significantly increased risk of pleural hemorrhage. |

Experimental-Tx |
100 patients |
Randomized trial to assess whether regular instillation of urokinase during abscess drainage leads to an improved outcome compared to saline irrigation alone. Patients were randomized between thrice daily urokinase instillation or saline irrigation alone. Patient medical records were reviewed to determine drainage, study group, Altona (PIA II) and Mannheim (MPI) scoring, duration of drainage, procedure-related complications, and hospital stay duration, and clinical outcome at the end of study. |
Technical success rate of the PAD was 100%. The success or failure of abscess remission did not differ significantly between groups (success rate of 91.5% in the urokinase group vs 88.8% in the saline group; failure rate was of 8.5% vs 21.2%, respectively); however, days of drainage, main hospital stay, and overall costs were significantly reduced in patients treated with urokinase compared to the control group (P<0.05). Surgical scores were a useful homogeneity factor, and MPI showed a good correlation with prognosis, while PIA results did not have a significant correlation. For drainage of complex abscesses (loculations, hemorrhage, viscous material), fibrinolytics safely accelerate drainage and recovery, reducing the length of the hospital stay and, therefore, the total cost. |

Experimental-Tx |
20 patients |
To determine if alteplase infusion for the treatment of loculated abdominopelvic abscesses requiring PCD was superior to saline solution infusion. |
There was no significant difference in the distribution of sex (P=.08) or age (P=.29). Abscess resolution was achieved in 9/11 alteplase-treated patients (80%) vs 3/9 saline solution-treated patients (33%). However, one patient in each group required repeat intervention within 30 days, for overall success rates of 73% vs 22%, respectively (P=.02). Having observed a significant difference in the primary outcome variable, the study was terminated early. A 3-day course of twice-daily alteplase infusion therapy is superior to normal saline solution for the treatment of loculated abdominopelvic abscesses. |

Review/Other-Dx |
18 Patients |
To evaluate the success of percutaneous drainage because of the seemingly frequent catheter-related problems, and occasional major complications, for many of the patients with intra-abdominal abscess (IAA). |
Percutaneous drainage was ultimately established in all patients with complete resolution of the abscesses occurring in 12 patients (67%). The average duration for drainage was 5.5 days (range 1-23). Average length of hospital stay after the establishment of drainage was 14.6 days (range 1-48). Six patients required surgical procedures because of inadequate abscess drainage (4) or continued clinical deterioration (2). There were no deaths. A major complication (colon perforation, enteric fistula) occurred in two patients (11%). Catheter-related problems were common (7/18 patients), and included drain migration (3), inadequate drainage, and catheter obstruction(2). Four patients required multiple percutaneous drainage procedures. Despite technical feasibility and clinical success in the majority of patients, percutaneous drainage of these intra-abdominal abscesses had frequent catheter-related complications. One-third of patients (31.8%) required surgical intervention despite a prolonged period (average 15 days) of percutaneous drainage. Patients demonstrated to have nonresolving abscesses by computer tomography (CT), abscesses associated with colonic diverticular disease of colon cancer, and abscesses localized to the left lower quadrant were noted to have less successful percutaneous abscess drainage. |

To analyze use of PCD in infected primary or metastatic abdominal tumors. |
Twelve of the patients improved clinically, as evidenced by defervescence and decrease or normalization of leukocytosis. Four patients did not respond to catheter drainage and required surgery. Three of the twelve who improved underwent operations for attempts at surgical cure or debulking of tumor volume despite an initial "good" response to percutaneous drainage. Of the nine patients who did not undergo surgery after percutaneous drainage, four underwent catheter removal after 5 weeks of drainage and had no recurrence of infection, two remained alive with the catheter in place up to 8 months and 1 year after drainage, and two died with the catheter in place. One patient had the catheter removed inadvertently after 3 weeks of drainage and had recurrences that required replacement of the catheter until his death. |

67 patients |
To analyze 67 cases of splenic abscess in a medical center of Taiwan during a period of 19 years. |
There were 41 males and 26 females with the mean age of 54.1+/-14.1 years. Multiple splenic abscesses (MSA) account for 28.4% and solitary splenic abscess in 71.6% of the patients. Twenty-six of sixty-seven patients (35.8%) had extrasplenic abscesses, with leading site of liver (34.6%). Microbiological cultures were positive in 58 patients (86.6%), with 71.8% in blood culture and 93.5% in abscess culture. Gram negative bacillus (GNB) infection predominated (55.2%), with leading pathogen of Klebsiella pneumoniae (22.4%), followed by gram positive coccus (GPC) infection (31%). Splenectomy was performed in 26 patients (38.8%), percutaneous drainage or aspiration in 21 (31.3%), and antibiotic therapy alone in 20 patients (29.9%). Eventually, 12 of 67 patients expired (17.9 %). By statistics, spleen infected with GNB was likely to develop multiple abscesses compared with infection with GPC (P=0.036). Patients with GNB infection (P=0.009) and multiple abscesses (P=0.011) experienced a higher mortality rate than patients with GPC infection and solitary abscess. The mean APACHE II score of 12 expired patients (16.3+/-3.2) was significantly higher than that of the 55 survivals (7.2+/-3.8) (P<0.001). |

To compare endoscopic and surgical cystogastrostomy for pancreatic pseudocyst drainage in a single-center, open-label, randomized trial. |
At the end of the follow-up period, none of the patients who received endoscopic therapy had a pseudocyst recurrence, compared with 1 patient treated surgically. There were no differences in treatment successes, complications, or re-interventions between the groups. However, the length of hospital stay was shorter for patients who underwent endoscopic cystogastrostomy (median, 2 days, vs 6 days in the surgery group; P < .001). Although there were no differences in physical component scores and mental health component scores (MCS) between groups at baseline on the Medical Outcomes Study 36-Item Short-Form General Survey questionnaire, longitudinal analysis showed significantly better physical component scores (P = .019) and mental health component scores (P = .025) for the endoscopy treatment group. The total mean cost was lower for patients managed by endoscopy than surgery ($7011 vs $15,052; P = .003). |

85 patients |
To compare the efficacy of percutaneous to surgical drainage in patients with pancreatic abscesses and pseudocysts. |
Percutaneous drainage of pancreatic abscesses in 18 patients cured three and palliated 12 who were eventually cured by elective surgical ablation; three patients died. This compares well to our 15 surgical patients, of whom four were cured by surgery alone and six were palliated. All were subsequently cured by additional computerized tomography-guided or ultrasound-guided percutaneous drainage and medical management or surgery. Five of the 15 died. Percutaneous drainage cured 11 of 14 infected pseudocysts and palliated two, which were subsequently cured by surgery; one was palliated but the patient was lost to follow-up. Surgical drainage cured six of 12 infected pseudocysts and palliated the other six, of which four were cured by further surgery and the other two were cured by secondary percutaneous drainage. Nine of 12 noninfected pseudocysts were cured by percutaneous aspiration, and two were palliated and later cured. In one patient, disease progressed, and he was ultimately lost to follow-up. Thirteen of 14 noninfected pseudocysts were cured by surgical drainage. The other patient died of pulmonary embolus. In patients treated by percutaneous techniques, there were four major complications. |

81 Patients |
To compare the outcomes of endoscopic drainage (ED) and percutaneous drainage (PD) for symptomatic pseudocysts. |
There were 81 patients, 41 who underwent ED and 40 who underwent PD, with no differences in age, sex, and comorbidity between the 2 groups. There were no differences in the rates of technical success (90.2% vs 97.5%; P Z .36), adverse events (14.6% vs 15%; P Z .96), and clinical success (70.7% vs 72.5%; P Z .86) between ED and PD, respectively. Patients who underwent PD had higher rates of reintervention (42.5% vs 9.8%; P Z .001), longer length of hospital stay (14.8 14.4 vs 6.5 6.7 days; P Z .001), and median number [quartiles] of follow-up abdominal imaging studies (6 [3.25, 10] vs 4 [2.5, 6]; P Z .02) compared with patients who underwent ED. |

Observational-Dx |
375 Patients |
To compare the outcome of patients with acute necrotic collection (ANC) and those with walled-off necrosis (WON), who had undergone percutaneous catheter drainage (PCD) as a part of management of acute pancreatitis (AP). |
Indications of PCD in 375 patients (258 with ANC and 117 with WON) were suspected infected pancreatic necrosis (n=214), persistent organ failure (n=117) and pressure symptoms (n=44). Need for additional surgical necrosectomy was seen in 14% patients with ANC and in 12% of patients with WON (p=0.364) and mortality was 19% in patients with ANC as compared to 13.7% in those with WON (p=0.132). There was no significant difference in the secondary outcome parameters between patients who underwent PCD for ANC or WON. Complications of PCD were comparable between patients with ANC and WON except development of external pancreatic fistula which occurred more often in patients with WON than in those with ANC (24.4% versus 34.2% respectively, p=0.034). |

To determine value of pancreatic catheter drainage (PCD) in treating patients with pancreatic abscess. |
We used percutaneous catheter drainage in 39 patients during 1987-1995. Only 9 of 29 (31 %) attempts at primary therapy were successful; 2 patients died, and 18 required subsequent surgical drainage. On the other hand, 14 of 14 patients with recurrent or residual abscesses after surgical drainage were successfully drained percutaneously. |

14 patients |
To report outcomes of patients with severe acute pancreatitis selected to undergo percutaneous drainage of pancreatic abscess, under CT scan guidance. |
Percutaneous drainage was performed as the primary treatment in 13 patients and for removal of a residual collection postoperatively in one patient. In two critically ill patients, percutaneous drainage was performed as a temporizing measure. In 12 patients with well-limited hypodense collections, percutaneous drainage was expected to result in the definitive cure of the abscess. Pigtail drains (No. 14F), were inserted using local anesthesia and CT scan guidance. Two patients had two drains and 12 patients had only one drain. Two patients were definitively cured by percutaneous drainage and all other patients were operated upon for removal of infected necrosis. |

To evaluate a new drainage technique for pancreatic pseudocysts or pancreatic abscesses entirely guided by endoscopic US and using an interventional echo endoscope with a linear curved array transducer. |
No major complication occurred except in one case of a pneumoperitoneum, which was managed medically. Placement of the 7-F nasocystic drain was successful in 18/20 cases of pancreatic abscess. Surgery was performed in the two other patients. Concerning the pancreatic pseudocysts, placement of an 8.5-French stent was successful in 10 patients and of a nasopancreatic drain in five patients. In one case, only a puncture-aspiration was performed. One recurrence among the 15 pancreatic pseudocysts and two relapses of the 18 pancreatic abscesses have been observed, over a mean follow-up of 27 months (6-48 months). EUS-guided drainage was successful in 31/35 patients (88.5%); only four patients with pancreatic abscesses underwent surgery. No bleeding occurred during the time of this study. |

Review/Other-Dx |
65 patients |
To describe the last 10 years' experience of the diagnosis and treatment of renal, perinephric, and mixed abscesses in an academic reference center. |
Perinephric abscesses were found in 33 (50.8%) patients, renal abscesses were found in 16 (24.6%), and 16 (24.6%) had mixed abscesses. Urolithiasis (28%) and diabetes mellitus (28%) were the most common predisposing conditions. The duration of symptoms before hospital admission ranged from 2 to 180 days (mean 20 days). Urine culture was positive in 43% of patients and blood culture was positive in 40% of patients. Most of the perinephric abscesses received an interventional treatment: surgical drainage (24%), percutaneous drainage (42%) or nephrectomy (24%). Most patients were cured (73.3%) on discharge from hospital. Mixed (renal and perinephric) abscess treatment was similar: percutaneous drainage (37.5%), surgical drainage (18.75%) or nephrectomy (37.5%). Most patients were cured (60%) on discharge from hospital. Renal abscesses, however, were treated medically in 69% of patients and 73% were cured on discharge from hospital. |

To evaluate CT-guided drainage in the treatment of lung abscesses. |
The abscess was cured (by clinical and radiographic criteria) in all 19 patients (100%), and surgery was avoided in 16 of the 19 patients (84%). Three patients underwent surgery for removal of organized tissue or decortication after the lung abscess was evacuated. Complications included a hemothorax that required a chest tube in one patient and three minor complications (a clogged catheter in two patients and transient elevation of intracerebral pressure in one patient). The hemothorax occurred in one of two patients in whom the catheter traversed normal lung. The percutaneous drainage catheters traversed juxtaposed abnormal pleura on route to the abscess in 17 of the patients. |

To assess percutaneous tube drainage in the treatment of lung abscess. |
All were successfully treated by percutaneous tube drainage initiated under local anesthesia, and all recovered completely. There were no relapses after a follow-up period of 2 to 5 years. During this period, we did not perform pulmonary resection for primary lung abscess. Three patients with malignant abscesses were also treated initially by transthoracic drainage but eventually required surgical intervention. It is concluded that percutaneous transthoracic drainage is an efficient and safe mode of treatment, and recommend transthoracic drainage as the treatment of choice for long-standing, refractory primary lung abscesses |

To evaluate the safety and effectiveness of CT-guided percutaneous drainage of lung abscesses considering success rate versus complications. |
Lung abscess completely resolved with no residual cavity in thirty three patients. Seven patients had residual cavity and surgery was performed. Thus, the success rate of radiological drainage of the lung abscesses (33/40) was 83%. Five (13%) patients developed pneumothorax. Three developed moderate pneumothorax and chest-tube needed to be inserted and two patients developed mild pneumothorax which was managed with aspiration. These patients were kept under observation and followed-up by chest X-rays. No other complications and no mortality occurred during the procedure for all the forty patients. |

Technical success was achieved in all 25 attempts (100%). 22/23 patients had complete resolution of the abscess without the need for surgical debridement, for a clinical success rate of 95.6%. One patient underwent technically and clinically successful abscess drainage but required surgical exploration for repair of an anastomotic leak after esophagogastrectomy. There was one complication. One patient had inadvertent placement of a catheter within a pulmonary vein. The catheter was removed after 24 hours without hemodynamic consequences. |

140 patients |
To assess the effectiveness of a computed tomographic (CT) image-guided transgluteal approach for percutaneous drainage of deep pelvic abscesses as an alternative to surgical drainage. |
The origins of the pelvic abscesses included postoperative fluid collection (n = 115), perforating appendicitis (n = 6), diverticulitis (n = 16), tubo-ovarian inflammation (n = 5), Crohn disease (n = 10), and internal bowel fistula due to irradiation (n = 2). The abscesses were 4-12 cm in diameter. The volume of the aspirate was 5-310 mL. Laboratory cultures of the aspirate grew mixed flora, but the organism most frequently isolated was Escherichia coli. Catheters were removed after a mean of 8 days. In 134 (96%) of 140 patients, there was complete resolution of the abscess following transgluteal drainage, without subsequent surgery. In six of 140 (4%) patients, incomplete resolution necessitated subsequent surgery for postoperative fluid collection (n = 3), diverticulitis (n = 2), or perforating appendicitis (n = 1). Complications of transgluteal drainage were rare and included hemorrhage in three (2%) of the 140 patients. There was no procedure-related mortality. A transpiriformis approach was significantly more likely to be associated with postprocedural pain (P <.001) than was an infrapiriformis approach. |

Transvaginal aspiration or drainage was successful in 19 (86%) of the 22 patients. Of the 3 patients in whom aspiration or drainage failed, all ultimately went on to have surgery despite undergoing repeated drainage procedures. Drainage catheters were placed in 15 (68%) of the 22 patients and left in place an average of 3.7 days. Aspiration alone resulted in a 100% success rate, whereas drainage with catheter placement resulted in an 80% success rate. No complications, including bleeding, bowel perforation, and death, were reported in any of the procedures. |

Transperineal needle placement was successful in 12 of 12 patients (100%). In procedures that required catheter placement, 10 of 11 placements (91%) were achieved with the transperineal approach. One patient required fluoroscopic transvaginal catheter placement after opacification of the collection transperineally. Catheter drainage was maintained for 2-146 days (mean, 40 days; median, 21 days). Clinical success was achieved in nine of 10 patients (90%) by means of transperineal drainage. There were no complications, although premature catheter removal occurred in two patients. |

N/A |
To evaluate current practice patterns of percutaneous image-guided abdominal and pelvic abscess drainage in academic and private practice centers. 493 questionnaires were sent to 193 academic and 300 private practice radiology departments in the United States. |
Academic centers returned 95 questionnaires (49%), and private practice centers, 72 (24%). Percutaneous abscess drainage is performed by a fellowship-trained radiologist at 92 (97%) of 95 academic centers and 41 (79%) of 52 private practice centers (P < .001). Among 95 academic respondents and 52 private practice respondents, respectively, 56 (59%) and 33 (63%) do not perform drainage if an abscess has a diameter of less than 3 cm; 30 (32%) and nine (17%), if the white blood cell count is normal; and 16 (17%) and six (12%), if the patient is afebrile. Most (90 [95%] of 95 academic, 45 [87%] of 52 private practice) respondents use conscious sedation. A transabdominal approach and 8-12-F catheters are most frequently used by both groups. Academic respondents more frequently use transvaginal and transrectal approaches (54 [57%] and 51 [54%] of 95, vs 16 [31%] and 15 [29%] of 52 private practice respondents; P = .003) and 14-F catheters (69 [73%] of 95 vs 18 [35%] of 52; P < .001). |

Observational-Tx |
163 patients |
To evaluate whether size of tuboovarian abscess (TOA) and other clinical characteristics were associated with the need for surgical intervention. |
A total of 163 patients with TOA were identified; 41 patients were excluded based on specific criteria. Of the remaining 122 women, 65.6% responded to antibiotic therapy, and 34.4% had surgery or ultrasound-guided drainage. Mean TOA size in the medical group was 4.4 cm as compared to 7.3 cm in the surgical group (p < 0.0001). Maximal leukocyte count, older age, and parity were associated with significantly higher risk of surgery. The significant univariate variables remained significant after multivariate analysis. ROC curve analysis revealed an excellent discrimination of the need for surgical treatment as predicted by TOA size, with increased likelihood of surgical or procedural intervention with increasing TOA size. |

57 TOAs drained in 49 female patients |
To analyze the authors' success with image-guided drainage of tuboovarian abscesses (TOAs). |
Thirty-three (58%) TOAs were drained percutaneously using computed tomography guidance and 24 were ultrasound guided (21 transvaginally, three transabdominally). Fifty-three TOAs were drained with catheter placement, and four were drained with aspiration alone. Abscess etiologies include pelvic inflammatory disease (n = 21, 37%), gastrointestinal conditions related (n = 21, 37%), gynecologic surgery (n = 8, 14%), and other (12%). Image-guided drainage resolved TOAs without salpingo-oophorectomy in 74% of cases overall (42 of 57) and 88% (29 of 33) of gynecologic-related cases, including 95% (20 of 21) of pelvic inflammatory disease cases. Salpingo-oophorectomy was performed more often in gastrointestinal-related cases (10 of 21, 48%) than for all other causes (five of 36, 14%; P < .001), with concurrent bowel surgery performed in the majority of the gastrointestinal-related cases. Mean follow-up after image-guided drainage was 48 months (range, 1-113) in patients who did not have related surgery. In patients who underwent salpingo-oophorectomy, it was performed on average 2.2 months (range, 0.5-5) after initial drainage. Two minor complications occurred; both involved catheter transgression of the urinary bladder in patients with transvaginal ultrasound-guided drainages. The patients were successfully treated conservatively with Foley catheter bladder decompression, without prolonged hospitalization. |

110 consecutive patients |
To evaluate the efficacy of laparoscopic appendectomy in patients with complicated appendicitis. |
There were two conversions due to extremely friable appendix. Laparoscopic appendectomy took longer to perform (98 min versus 79 min) but was associated with less analgesic use, shorter median hospital stay (LA- 3 days; OA- 6 days, p<0.05), and lower rate of wound infections (LA, 8.2%; OA, 24.6 %, p<0.05). Intra-abdominal abscess occurred in four patients (8.2%) in LA group and fourteen patients (22.9%) in OA group (p<0.05). More patients in OA group experienced prolonged ileus than LA group but the difference was statistically insignificant. All complications were managed conservatively and there was no mortality in either group. |

14 patients |
To evaluate the clinical efficacy of EUS-guided trans-rectal/transcolonic drainage of pelvic abscess without fluoroscopy. |
Fourteen consecutive patients were enrolled. EUS-guided aspiration was performed in three patients. In two patients, dilatation and aspiration was performed, while trans-rectal stent was placed in nine patients. All patients became afebrile within 72 h. Stent was removed in all patients, after confirming the resolution of the abscess on repeat computed tomography after 7 days. One patient in whom only aspiration was done had recurrence of fever and abscess on the seventh day and was treated by surgical drainage. A follow-up EUS done in 13 of the patients after 3 months revealed no recurrence, and all patients were asymptomatic at 6 months. The procedure was uneventful in all patients. |

Review/Other-Dx |
971 patients underwent 2,045 HAE procedures |
To identify clinical factors associated with postembolization abscess, which may improve management and outcome. |
From January 1998 to January 2010, 971 patients underwent 2,045 HAE procedures. Fourteen patients developed a pyogenic hepatic abscess after embolization, for an overall rate of 1.4%. Thirty-four patients (4%) had a history of bilioenteric anastomosis (BEA) and 21 patients (2%) lacked a competent sphincter of Oddi because of the presence of a biliary stent (n = 19) or a previous sphincterotomy (n = 2). Eleven of the 34 patients with a BEA (33%) and two of 21 patients with an incompetent sphincter (10%) developed abscesses, in contrast to only one abscess (0.05%) among the 916 patients with apparently normal sphincters (0.1%; odds ratio, 437.6; 95% CI, 54.2-3,533; P < .0001). Gram-negative and Gram-positive aerobes were the most common bacteria isolated after drainage. Percutaneous drainage was the initial management strategy in all patients; two patients (14%) required subsequent surgical drainage and hepatectomy, and three (21%) died. |

Review/Other-Dx |
161 patients |
To compare the clinical characteristics of patients with Streptococcus milleri (SM) and Klebsiella spp. associated pyogenic liver abscess (PLA). |
From 2000 to 2009 inclusive, 21 and 140 patients had SM and Klebsiella spp. associated monomicrobial infected PLA, respectively. A higher incidence of active malignancy occurred in the SM group (14.3% vs. 3.6%, p < 0.03). The common clinical features of the patients were fever, chill and right upper quadrant pain. A longer duration (6.3 vs. 4.4 day, p = 0.04) of symptoms and a higher incidence of hepatomegaly (14.3% vs. 2.9%, p < 0.01) occurred in the SM group. Common laboratory and imaging abnormalities included: anemia, leukocytosis, high erythrocyte sedimentation rate and C-reactive protein, hypoalbuminemia, elevated total bilirubin and alanine aminotransferase, right hepatic lobe involvement, hypoechoic in ultrasonograpghy, rim enhancement and septal lobulation in computed tomography. The biliary tract disorder was the most common cause of the disease in the two groups. Patients with Klebsiella spp. associated PLA tended to have more complications: bacteremia (61.6% vs. 31.6%, p < 0.01) septic shock (33.6% vs. 19%, p = 0.11), disseminated intravascular coagulation (20.7% vs. 4.8%, p = 0.04), metastatic infections (10.7% vs. 0%, p = 0.06), acute renal and respiratory failure (5% vs. 0%, p = 0.14). However, both were effectively managed by the combination of antibiotics and image-guided aspiration with/without drainage, and their mortality rates were comparable to each other. Those patients with metastatic infection might need a longer duration (6.07 vs. 5.32 week, p = 0.144) of antibiotic therapy, which was due to the longer mean duration (3.85 vs. 2.86, p < 0.04) of an intravenous counterpart. |

60 Patients |
To determine the effectiveness of percutaneous catheter drainage (PCD) and to compare PCD with percutaneous needle aspiration in the management of liver abscess. |
Percutaneous needle aspiration was successful in 20 (67%) of the 30 patients after one (n = 12), two (n = 7), or three (n = 1) aspirations. PCD was curative in all 30 patients after one (n = 24) or two (n = 6) procedures. All abscesses 50 mm or less in longest diameter were successfully managed, 10 by percutaneous needle aspiration and 12 by PCD. None of patients in the percutaneous needle aspiration group with multiloculated abscesses (n = 5) was successfully treated. Hospital stay did not differ significantly between the groups. There were no complications related to the procedure. |

107 Patients |
To evaluate the role of surgical treatment in pyogenic abscesses and to determine an optimal treatment algorithm. |
Our study consisted of 107 patients with pyogenic liver abscess. The success rate for small abscesses treated with antibiotics was 100 percent. The success rate with antibiotics and percutaneous drainage for large, unilocular abscesses was 83 percent and for large, multiloculated abscesses was 33 per cent. None of the 27 patients who had surgical therapy for large, multiloculated abscesses had recurrences. Surgical treatment for large (>3 cm), multiloculated abscesses had a significantly higher success rate than percutaneous drainage plus antibiotic therapy (33% versus 100%, P < or = 0.01). The mortality rate for the percutaneous drainage plus antibiotic group was not significantly different from the primary surgical group (4.2% versus 7.4%, P = 0.40). |

To perform a prospective study of the endoscopic management of liver abscess communicating with bile ducts. |
Of the total of 586 patients with liver abscesses, seen over a 10-year period, there were 38 (30 amebic, 8 pyogenic) patients who developed a biliary fistula between the liver abscess cavity and the intrahepatic bile ducts (right intrahepatic bile ducts in 30 patients, left intrahepatic bile ducts in 8 patients). We performed either endoscopic sphincterotomy with insertion of a nasobiliary drain (n = 18) or endoscopic sphincterotomy with biliary stenting (n = 20). The fistulas healed in all patients after a median time of 6 days (range 4–40 days) after endoscopic treatment. The nasobiliary drainage catheters and stents were removed after 8–40 days of their placement. |

Of a total of 525 patients with hepatic abscesses or cysts who were seen over a 5-year period, there were 26 patients who developed a demonstrable communication between liver abscesses (n = 20; 16 amebic, four pyogenic) or hydatid cysts (n = 6) and intrahepatic bile ducts (right intrahepatic bile ducts in 22 patients, left intrahepatic bile ducts in four patients). We performed either sphincterotomy with insertion of a nasobiliary drain (n = 20) or sphincterotomy with biliary stenting (n = 6). The fistulas healed in all patients after a mean time of 4 days (range 2-20 days) after endoscopic treatment.

To review records of patients with pyogenic live abscess to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics, aspiration, or catheter drainage was an effective alternative to open drainage. |
Twenty-nine patients were treated with broad-spectrum antibiotics and diagnostic aspiration. Twenty-three (79%) recovered uneventfully, and six required catheter or operative drainage. Twenty-three patients (including five who failed aspiration) underwent drainage with percutaneously placed catheters. Nineteen (83%) recovered; four required open surgical drainage. Of seven patients who required open surgical drainage, six recovered. One (2%) of the 54 patients died following failed aspiration and catheter and surgical drainage.

In total, 103 liver abscess patients were treated at our center. The mortality was 9%. The main symptoms were fever and abdominal pain. All of the patients had CRP > 6 g/dL. Sixty-nine patients had a unique abscess. Seventeen patients were treated with antibiotics alone and 57 with percutaneous drainage and antibiotics. Twenty-seven patients who were treated with percutaneous techniques required surgery, and 29 patients initially received it. Eventually, 43 patients underwent abscess surgery. The factors associated with failed medical treatment were gas-forming abscess (P = 0.006) and septic shock at the initial presentation (P = 0.008). |

63 Patients |
To describe our own experience with pyogenic liver abscesses over the past 10 years and investigate the risk factors associated with failure of initial percutaneous therapy. |
Sixty-three patients (42 males, 21 females) aged 65 (± 14) years [mean ± (SD)] had prodromal symptoms for a median (interquartile range; IQR) of 7 (5-14) d. Only 59% of patients were febrile at presentation; however, the serum C-reactive protein was elevated in all 47 in whom it was measured. Liver function tests were non-specifically abnormal. 67% of patients had a solitary abscess, while 32% had > 3 abscesses with a median (IQR) diameter of 6.3 (4-9) cm. Causative organisms were: Streptococcus milleri 25%, Klebsiella pneumoniae 21%, and Escherichia coli 16%. A presumptive cryptogenic cause was most common (34%). Four patients died in this series: one from sepsis, two from advanced cancer, and one from acute myocardial infarction. The initial procedure was radiological aspiration ± drainage in 54 and surgery in two patients. 17% underwent surgical management during their hospitalization. Serum hypoalbuminaemia [mean (95% CI): 32 (29-35) g/L vs 28 (25-31) g/L, P = 0.045] on presentation was found to be the only factor related to failure of initial percutaneous therapy on univariate analysis. |

To determine whether first-line treatment with percutaneous or surgical drainage of liver abscesses larger than 5 cm results in better clinical outcome. |
PD was performed in 36 patients and SD in 44 patients as first-line treatment. Clinical, laboratory, and abscess parameters were comparable in both groups. Sixty-four of 80 patients (80%) had multiloculated abscess. The time to defervescence of fever was not statistically significant (PD versus SD, 4.85 versus 4.38 days; P = 0.09). However, SD had less treatment failures (3 versus 10, P = 0.013), less requirement for secondary procedures (5 versus 13, P = 0.01), and shorter length of hospital stay (8 versus 11 days, P = 0.03). There was no difference in morbidity or mortality rates. |
