PC is a radiological intervention used in the management of high-risk patients with AC. A retrospective study of outcomes following PC, including success rates, complications, AC resolution, readmissions, and subsequent cholecystectomy. Our database identified 28 patients (14M:14F), median age 73 (range 40-93). 82% were ASA III/IV. Median follow-up was 2 (range 0-8) years. Imaging suggested AC in 61% and empyema in 39%. 86% were calculous. All procedures were USS-guided with 100% success. AC resolution occurred in 89.3%. Of three unresolved, there was 1 death day-1 post-PC (non-procedure related), 1 index cholecystectomy, 1 chronic complicated cholecystitis. 28.6% developed complications, 2 major (1 late biliary peritonitis and 1 cholecystocutaneous fistula with abdominal wall abscess), 17.9% dislodged drain, 10.7% other. 20 patients had bile cultures (70% positive, mainly gram-negative). 17.9% patients were readmitted with AC, 1 had repeat PC. 21.4% had subsequent ERCP. 32.1% underwent subsequent cholecystectomy, 1 laparoscopic cholecystectomy(LC) index, 4 elective (3 LC, 1 open), 4 emergency (2 LC, 1 LC subtotal, 1 failed open with drain insertion). PC is both safe and effective with significant procedural success rates and resolution rates. There are few major complications but significant morbidities, mainly dislodged drains. One-third of patients have subsequent cholecystectomy.
