percutaneous hepatic Abscess Drainage do multiple Abscesses or multiloculated Abscesses preclude Drainage or affect outcome
Journal of Vascular and Interventional Radiology, 2009Co-Authors: Debra A Gervais, Ronald S Arellano, Peter F Hahn, Raul N Uppot, Peter R MuellerAbstract:Purpose To compare the effectiveness of percutaneous Abscess Drainage in patients with pyogenic liver Abscesses of the following types: single, single multiloculated, multiple, and multiple multiloculated. Materials and Methods One hundred nine patients with 149 liver Abscesses who underwent percutaneous Drainage during an 11-year period were divided into a single Abscess group and a multiple Abscess group. Of the 109 patients, 54 had multiloculated Abscesses and were divided into single and multiple multiloculated Abscess groups. Technical success was defined as the ability to place the catheter within the Abscess cavity and clinical success was defined as improvement in the patient's symptoms. Clinical findings, management strategy, complication rate, and success rate were analyzed. Results Technical success rates were 96% (82 of 85) for a single Abscess and 96% (23 of 24) for multiple Abscesses ( P = 1.0). Clinical success was achieved in 74 of 85 patients (87%) with a single Abscess and 22 of 24 patients (92%) with multiple Abscesses ( P = .729). Technical success rates were 94% (32 of 34) for a single multiloculated Abscess and 95% (19 of 20) for multiple multiloculated Abscesses ( P = 1.0). Clinical success was achieved in 30 of 34 patients (88%) with a single multiloculated Abscess and 18 of 20 patients (90%) with multiple multiloculated Abscesses ( P = 1). No significant difference in hospital stay was seen between single and multiple Abscess groups ( P = .373) or between single multiloculated and multiple multiloculated Abscess groups ( P = .180). There were no major complications or mortality related to the procedure. Conclusions Percutaneous Drainage is a safe and effective procedure in the treatment of pyogenic liver Abscess, regardless of Abscess complexity and/or multiplicity.

percutaneous imaging guided abdominal and pelvic Abscess Drainage in children
Radiographics, 2004Co-Authors: Debra A Gervais, Mukesh G Harisinghani, Stephen D Brown, Susan A Connolly, Sherry L Brec, Peter R MuellerAbstract:Percutaneous imaging-guided Drainage is the first-line treatment for infected or symptomatic fluid collections in the abdomen and pelvis, in the absence of indications for immediate surgery. The technology and expertise needed to perform percutaneous Abscess Drainage are widely available and readily adapted for use in the pediatric population. Catheter insertion procedures include the trocar and Seldinger techniques. Imaging guidance for Drainage is most commonly performed with ultrasonography (US), computed tomography, or US and fluoroscopy combined. Abscesses in locations that are difficult to access, such as those deep in the pelvis, subphrenic regions, or epigastric region, can be drained by using the appropriate approach—transrectal, transgluteal, intercostal, or transhepatic. Although the causes of Abscesses in children differ slightly from those of Abscesses in the adult population, the frequency of successful treatment with percutaneous Abscess Drainage in children is 85%–90%, similar to that in a...

recurrent abdominal and pelvic Abscesses incidence results of repeated percutaneous Drainage and underlying causes in 956 Drainages
American Journal of Roentgenology, 2004Co-Authors: Debra A Gervais, Ronald S Arellano, Peter F Hahn, Mary Jane Oneill, Chihi Ho, Peter R MuellerAbstract:OBJECTIVE. We undertook this study to determine the incidence and results of repeated (secondary) percutaneous Abscess Drainage performed on recurrent Abscesses after successful initial (primary) percutaneous Abscess Drainage.MATERIALS AND METHODS. Imaging studies from patients who underwent multiple Drainages were reviewed to define a cohort of patients who underwent secondary percutaneous Abscess Drainage after successful initial percutaneous Abscess Drainage of the same Abscess. Medical records of these patients were then reviewed to assess the results of secondary percutaneous Abscess Drainage.RESULTS. 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 drainag...

percutaneous Abscess Drainage in crohn disease technical success and short and long term outcomes during 14 years
Radiology, 2002Co-Authors: Debra A Gervais, Peter F Hahn, Mary Jane Oneill, Peter R MuellerAbstract:PURPOSE: To determine technical success with percutaneous Abscess Drainage (PAD) in patients with Crohn disease during 14 years. MATERIALS AND METHODS: Medical records of 32 patients with Crohn disease who underwent PAD from 1985 to 1999 were reviewed. Results of Abscess Drainage and nature of subsequent surgical procedures were recorded. Factors assessed included postoperative or spontaneous nature of the Abscess, documentation of a proved fistula, history of occurrence of prior Abscesses, duration of Crohn disease, and use of steroid treatment. Technical success was defined as complete Abscess Drainage. Short-term success was defined as avoidance of surgery within 60 days of Drainage. Long-term success was defined as avoidance of surgery beyond the initial 60-day period. Short-term avoidance of surgery was assessed as a predictor of the need for surgery in the long term. Statistical analysis was performed with the χ2 test to evaluate predictors of short-term success and to assess short-term success as a...

CT-Guided transgluteal Drainage of deep pelvic Abscesses in children: selective use as an alternative to transrectal Drainage.
American Journal of Roentgenology, 2000Co-Authors: Debra A Gervais, Peter F Hahn, Mary Jane O'neill, Peter R MuellerAbstract:OBJECTIVE. The transgluteal approach to Abscess Drainage through the greater sciatic foramen has been described in adults, but this route has not been as extensively studied in children. We performed CT-guided transgluteal percutaneous Abscess Drainage in seven children and assessed the results of Drainage and catheter tolerance.CONCLUSION. Transgluteal catheters are well tolerated by children, and the transgluteal route is an effective approach to selected pelvic Abscesses in children.

Percutaneous Biopsy and Abscess Drainage in the Abdomen and Pelvis
2020Co-Authors: Connor A. Morton, Debra A Gervais, Justin J. Campbell, Sudhen B. Desai, Albert A. Nemcek, Robert J. LewandowskiAbstract:Abstract The expansion in the use of image-guided percutaneous biopsy and abdominopelvic Abscess Drainage reflects the ability of these procedures to offer safe minimally invasive techniques with superior outcomes compared with previously utilized operative approaches. Advances in technique, instruments, and imaging modalities have made these procedures among the most commonly performed in both the inpatient and outpatient setting. Increasing demands from patients, referring physicians, and hospitals to offer and excel in these procedures highlight their importance.

endoscopic ultrasound guided Abscess Drainage
Gastrointestinal Endoscopy Clinics of North America, 2012Co-Authors: Ganapathy A Prasad, Shyam VaradarajuluAbstract:: Abdominal and pelvic Abscesses have traditionally been drained by percutaneous techniques or surgery. While surgical Drainage is associated with considerable morbidity and mortality, percutaneous techniques are associated with the need for multiple interventions, increased length of hospital stay, and an indwelling external catheter for prolonged periods. Endoscopic ultrasound (EUS) is a minimally invasive but highly effective technique that enables internal Drainage of the Abscess. Although data are limited, evidence supporting its clinical efficacy is increasing rapidly. This article summarizes the current status of EUS-guided approach for Drainage of gastrointestinal Abscess collections.

Computed tomography-guided percutaneous Abscess Drainage in intestinal disease
Diseases of the Colon & Rectum, 1997Co-Authors: Andrea Bernini, Michael P. Spencer, W. Douglas Wong, David A. Rothenberger, Robert D. MadoffAbstract:PURPOSE: This study was designed to assess the efficacy of computed tomography-guided percutaneous Abscess Drainage in intestinal disease. METHODS: Retrospective chart review of patients who underwent percutaneous Abscess Drainage for complications of intestinal disease with or without surgery between 1990 and 1994. RESULTS: Eighty-two patients with 111 Abscesses were identified. Causes of Abscess included anastomotic leaks (35 percent), postoperative complications without leak (30 percent), and diverticular disease (23 percent). Complete success (no surgery necessary) was achieved in 53 of 82 patients (65 percent). Nine patients (11 percent) who underwent interval surgery were classified as having partial successes. Twenty-six of 26 (100 percent) well-defined unilocular collections containing pus were successfully drained. Complex Abscesses (loculated, poorly defined, multiple, associated with fistula, draining feces) were successfully drained in 35 of 55 patients (63 percent). Success rates varied inversely with the number of complicating factors present. Apache II scores of 15 or higher were associated with decreased success rates. CONCLUSION: Percutaneous Abscess Drainage is a highly successful technique for treatment of patients with intra-abdominal infection related to intestinal disease. Although several factors are associated with decreased success rates and multiple complicating factors combine to reduce success rates, no identifiable factor or combination of factors preclude the possibility of a successful outcome .
