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.
