Safety and Efficacy of Percutaneous Gallstone Extraction in High-Risk Patients: An Alternative to Cholecystectomy or Long-Term Drainage?

Abstract

Acute cholecystitis in nonsurgical candidates is often managed with cholecystostomy tube drainage. After symptom resolution, management options include cholecystectomy, long-term tube drainage, or tube removal. Percutaneous cholecystolithotomy (PCCL) can offer another therapeutic option for patients who are poor operative candidates. A retrospective study of PCCL performed between December 2000 and September 2017 was conducted. Demographic characteristics, procedure details, gallstone-related complications, procedure-related complications, readmission, and mortality data were collected. Seventy-five patients were identified (52.0% male, 48.0% female, mean ± SD age 75.6 ± 13.9 years). Mean ± SD follow-up time was 2.8 ± 3.7 years. Most of the patients (90.7%) had an American Society of Anesthesiologists physical status classification of 3 or 4. Eleven patients (14.7%) had failed earlier cholecystectomy. A total of 96 PCCL procedures were performed, and complete gallstone removal was achieved in 68 of 75 patients (90.7%), including all patients with previously aborted cholecystectomy. The 30-day and 90-day readmission rates were 4% and 8%, respectively. Three patients (3.9%) subsequently underwent cholecystectomy after PCCL. Ten (10.4%) procedure-related complications (Clavien-Dindo grade I and II) and 17 (22.7%) gallstone-related complications occurred during the follow-up period. Postprocedural choledocholithiasis occurred in 6 patients (8.0%). Recurrent gallstones developed in 5 patients (6.3%) (3 patients undergoing cholecystectomy and 2 patients treated with cholecystostomy tube). PCCL is a viable option for management of symptomatic gallbladder stones in high-risk surgical patients. There is a high technical success rate, even in patients with earlier failed cholecystectomy. Most patients (77.3%) avoided gallstone-related complications after the procedure.
