Introduction: Percutaneous cholecystostomy tube (PCT) placement is considered a safe alternative to cholecystectomy for the treatment of acute calculous cholecystitis (ACC), but data regarding long-term outcomes following PCT are limited.
Methods: We retrospectively reviewed our institutional experience of patients undergoing PCT for ACC between 1997 and 2015. Recurrent biliary events were defined as cholecystitis, cholangitis, or gallstone pancreatitis.
Results: PCT was placed for 288 patients with ACC. Mean age and age-adjusted Charlson comorbidity index were 72 ± 15 years and 5.3 ± 2.4, respectively. Following PCT placement, 91% of patients successfully resolved their episode of ACC. PCT dysfunction occurred in 132 patients (46%), with 80 patients (28%) requiring re-intervention, while 7% developed procedure-related complications. Interval cholecystectomy reduced the risk of recurrent biliary events to 7% from 21% (p = 0.002). Cholecystectomy was completed laparoscopically in 45% of patients receiving an interval operation vs. 22% of those undergoing urgent surgery for PCT failure or recurrent biliary event (p = 0.03).
Conclusions: PCT placement is a highly successful treatment for acute calculous cholecystitis and is associated with low complication rate, but high rate of tube dysfunction requiring frequent re-intervention. Interval cholecystectomy is associated with a decreased likelihood of recurrent biliary events and increased likelihood of successful laparoscopic completion.
