PURPOSE: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominal abscesses or fluid collections. MATERIALS AND METHODS: We performed PCD for 165 abscesses and fluid collections in 148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). The lesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreatic space in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrence rates, the causes of failure or recurrence, the mean duration of drainage, and the complications of PCD. RESULTS: Of the 165 cases, one hundred-fifty nine(96.5%) were successfully cured, Although a partial success could be achieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the main causes of the unsullessful cases. The duration of drainage rainged from 2 to 605 days (mean, 1 days). Complications occured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleura in 2, bowel perforation in 2, and bleeding through catheter in 1. CONCLUSION: PCD is an effective and safe method for various abdominal abscesses or fluid collections.
