Comparison of Laparoscopic Common Bile Duct Exploration with Endoscopic Retrograde Cholangiopancreatography for Common Bile Duct Stones After Cholecystectomy.

Background: Few studies have focused on the treatment of common bile duct (CBD) stones after cholecystectomy, for which optimal treatment options remain unclear. Aims: To compare the safety and efficacy of laparoscopic common bile duct exploration (LCBDE) versus endoscopic retrograde cholangiopancreatography (ERCP) for CBD stone treatment after cholecystectomy. Materials and Methods: A total of 201 patients were enrolled in this retrospective cohort study, of whom 134 with ≤3 stones and a maximum stone diameter of <15 mm were classified as subgroup 1, and 67 with >3 stones or a maximum stone diameter of ≥15 mm were classified as subgroup 2. Perioperative characteristics were also analyzed. Results: ERCP subgroup 1 exhibited a shorter operative time (P < .001), postoperative hospital stay (P < .001), and lower incidence of bile leakage (P = .034) than LCBDE subgroup 1. ERCP subgroup 2 exhibited a shorter operative time (P < .001) and shorter postoperative hospital stay (P < .001) than LCBDE subgroup 2. However, LCBDE subgroup 2 exhibited a greater rate of complete stone removal (P = .044) and a lower incidence of acute pancreatitis (P = .037) than ERCP subgroup 2. Conclusions: For treatment of CBD stones after cholecystectomy, ERCP was superior in cases involving ≤3 stones and a maximum stone diameter of <15 mm. Among those with >3 stones or maximum stone diameter of ≥15 mm, LCBDE demonstrated certain advantages.
