Laparoscopic Common Bile Duct Exploration with Gallbladder Preservation: An Innovative Technique for Primary Common Bile Duct Stones

Background: Primary common bile duct (CBD) stones can be treated with laparoscopic CBD exploration (LCBDE), during which cholecystectomy is routinely performed. For patients without gallstones, we have developed a new procedure, LCBDE with gallbladder preservation. The purpose of this study was to evaluate the management of LCBDE with gallbladder preservation at our institution. Methods: Retrospective analysis the clinical data of 105 patients with primary CBD stones. Demographic data, clinical characteristics, preoperative risk factors, and postoperative complications were evaluated. Results: All patients were divided into two groups depending on the presence of gallstones: the primary CBD stone coexistence gallstones group (Group A, n = 15) and the primary CBD stones absence gallstones group (Group B, n = 90). Complete stones clearance was achieved in all patients. There were no significant differences in postoperative complications rates and mortality between the two groups. The mean postoperative hospital stay was 3.2 days for Group A and 4.1 days for Group B (P = .03). Conclusion: This study found that LCBDE with gallbladder preservation can effectively and safely treat primary CBD stones without gallbladder stones.
