Abstract:

Objective

To investigate the safety and efficacy of laparoscopic surgeries for choledocholithiasis after cholecystectomy.

Methods

A retrospective analysis was performed on the clinical data of 26 patients who underwent laparoscopic surgeries for choledocholithiasis after cholecystectomy in Beijing Electric Power Hospital of State Grid Corporation from May 2018 to February 2025. According to the surgical methods, the patients were divided into laparoscopic common bile duct exploration group (LCBDE, 19 cases) and laparoscopic transcystic common bile duct exploration group (LTCBDE, 7 cases), and perioperative indicators were compared between the two groups. The impact of previous surgical methods on perioperative indicators was analyzed in subgroups.

Results

The length of residual cystic duct in the LTCBDE group was significantly longer than that in the LCBDE group [(1.7±0.7) cm vs (1.0±0.3) cm, P<0.05], and the postoperative hospital stay was significantly shorter than that in the LCBDE group [(8.1±2.3) d vs (15.3±3.4) d, P<0.05]. There were no statistically significant differences between the two groups in the interval from disease onset, the number and size of stones, preoperative blood tests, operation time, intraoperative blood loss, or postoperative complications. The previous surgical method was not related to the surgical time, intraoperative bleeding, or postoperative hospital stay. During the postoperative follow-up period of 3 to 83 months, no delayed biliary injuries or recurrence of common bile duct stones were observed.

Conclusions

Laparoscopic surgery is safe and feasible for patients with choledocholithiasis after cholecystectomy. LTCBDE has obvious advantages, and the laparoscopic surgical approach can be individually selected based on factors such as the length of the residual cystic duct.
