Purpose: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominalabscesses or fluid collections. Materials and Methods: We performed PCD for 165 abscesses and fluid collections in148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). Thelesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreaticspace in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrencerates, 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 beachieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the maincauses of the unsullessful cases. The duration of drainage rainged from 2 to 605 days(mean, 1 days). Complicationsoccured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleurain 2, bowel perforation in 2, and bleeding through catheter in 1. Conclusion: PCD is an effective and safe methodfor various abdominal abscesses or fluid collections.
