Percutaneous drainage of an intra-abdominal abscess is utilized frequently. To evaluate its effectiveness at our institution over 16 months, 18 patients (mean age 49 years) who underwent radiologically directed percutaneous drainage of intra-abdominal abscesses were retrospectively reviewed. The abscesses were postoperative in 14 patients (laparotomy, 5; appendectomy, 4; colectomy, 3; hysterectomy, 2). ⋯ CT-directed percutaneous drainage of intra-abdominal abscesses provides an alternative to immediate surgical intervention. The preliminary findings from this study suggest a limited application of this intervention in one-third of patients. Further detailed analysis of this patient group is required to delineate guidelines for identifying those patients where percutaneous drainage is unlikely to be successful.
