Choledocholithiasis recurrence following laparoscopic common bile duct exploration

Area of Science:

• Gastroenterology
• Surgical Innovation
• Biliary Tract Disease

Background:

• Choledocholithiasis (bile duct stones) can be managed endoscopically or surgically via laparoscopic common bile duct exploration (LCBDE).
• While endoscopic treatment recurrence is studied, risk factors for recurrence after LCBDE require further investigation.

Purpose of the Study:

• To identify risk factors associated with choledocholithiasis recurrence following LCBDE.
• To analyze the impact of various clinical and surgical factors on post-LCBDE stone recurrence.

Main Methods:

• A retrospective analysis of 156 patients who underwent LCBDE between February 2004 and July 2016.
• Univariate and multivariate analyses were performed to assess associations between recurrence and patient demographics, comorbidities, surgical details, and postoperative outcomes.

Main Results:

• The overall recurrence rate for choledocholithiasis after LCBDE was 14.1%, with a mean recurrence time of 38.18 months.
• Age emerged as the sole independent risk factor for stone recurrence in both univariate and multivariate analyses.
• No patients under 55 developed recurrent stones, while 86.4% of recurrences occurred in patients over 65.

Conclusions:

• Increasing age is the only significant independent risk factor for choledocholithiasis recurrence after LCBDE.
• Distinct mechanisms may underlie bile duct stone formation in younger versus older patient populations.
