Abstract:

OBJECTIVE: Although the majority of abdominal and pelvic abscesses can be drained through straightforward, a number of abscesses or fluid collections initially appear unsuitable for percutaneous drainage due to difficult access. The aim of this study is to evaluate the efficacy of percutaneous drainage using CT in intraabdominal abscesses, which have difficult access. MATERIALS and METHODS: We evaluated, retrospectively, 13 patients who had abdominal abscess or collection with difficult access and who underwent percutaneous drainage using CT guidance between 2004 and 2008. The abscesses and collections were localized in the liver in two patients, in the spleen in two patients, in the perigastric -subdiaphragmatic area and gallbladder fossa in four patients, and in the pelvic region in five patients. We used alternative drainage access such as transhepatic, transgluteal course in addition to conventional access routes. RESULTS: Percutaneous drainage catheters were placed using Seldinger technique into 12 patients. In one patient, the drainage catheter was not inserted because of initial aspirated material was serous. Drainage catheters were held in collection site until draining material reduced under 10cc daily. In these patients, collections successfully drained all of them but one whom underwent operation due to an interloop abscess two days after placement of drainage catheter. CONCLUSION: Abdominal abscesses which have difficult access can successfully be drained using additional alternative drainage routes byCTguidance.
