<b>Objectives:</b> To evaluate the effectiveness of ultrasound (US) guided percutaneous abscess drainage in the treatment of adult patients with perforated appendicitis and to estimate the success rate.<br> <b>Material and methods:</b> Pre-interventional computed tomography examinations of patients (n=63) who had abscess formation due to perforated appendicitis were reviewed retrospectively. A total of 15 patients [6 (40%) women and 9 (60%) men] with a mean age of 42±21 (SD) years who underwent US-guided percutaneous abscess drainage were enrolled in this study. Abscess volume, location, catheter duration and follow-up results were recorded. The treatment effectiveness of US-guided percutaneous abscess drainage was investigated.<br> <b>Results:</b> A total of 15 patients were included. Abscess formations were in right lower quadrant (n=10) and deep pelvic area (n=5). The mean abscess volume was 235 mm³ (range: 20 - 1180). The mean catheter duration was 12.2 ± 7.8 days (range: 3 - 30). Five patients (5/15, 33%) were treated non-surgically with complete response. In remaining 10 patients (10/15, 67%), surgical management was required because of recurrent abscess (3/15, 20%) and progression in abscess volume (7/15, 47%). The technical success rate and the clinical success rate was 100%, and 33%, respectively.<br> <b>Conclusion:</b> Because of our low clinical success rate with 33%, we recommended US-guided percutaneous abscess drainage in perforated appendicitis for some selected patients with high risk surgery.
