Percutaneous Transcholecystic Removal of Common Bile Duct Stones: Case Series in 114 Patients

Abstract

Purpose To evaluate the safety and effectiveness of percutaneous transcholecystic removal of common bile duct (CBD) stones in 114 patients. Materials and Methods This retrospective study was approved by the institutional review board. From September 2011 through February 2017, 114 consecutive patients (68 men, 46 women; mean age, 73 years) underwent percutaneous transcholecystic removal of CBD stones. All patients had acute cholangitis or cholecystitis. Stones were extracted through a 12-F sheath by using a Wittich nitinol stone basket uder fluoroscopic guidance. Technical success rates, complications, and long-term follow-up were evaluated. Results Technical success was achieved in 96 of 114 (84.2%) patients. In 18 patients, stone removal was unsuccessful due to failure of cystic duct cannulation (n = 11), proximal migration of the CBD stone (n = 3), multiple CBD stones (n = 3), and low insertion of the cystic duct (n = 1). No major procedure-related complications were seen. During the mean follow-up of 644 days (range, 11-2206 days), CBD stones recurred in 12 patients after a mean of 884 days (range, 439-1799 days) after the procedure. Conclusion Percutaneous transcholecystic removal of common bile duct stones seems to be a safe and effective method. © RSNA, 2018 Online supplemental material is available for this article .
