Minimally Invasive Common Bile Duct Stone Management in Gastric Bypass Patients: Laparoscopic Common Bile Duct Exploration with Disposable Bronchoscope

Abstract

Background: Bariatric surgery patients may develop common bile duct stones, and the alterations in their anatomy present challenges in treating this condition. Methods such as laparoscopic bile duct exploration is impractical in many healthcare facilities, due to the absence of a choledochoscope. This study assesses the feasibility of laparoscopic exploration of the common bile duct using a disposable bronchoscope in these individuals.

Method: The study involved 32 participants who had undergone gastric bypass surgery. These participants presented with both bile duct stones and bile ducts exceeding 8 mm in diameter, diagnosed through either MRCP or cholangiography conducted during the surgery. Stone extraction was carried out through either choledotomy or transcystic routes using a disposable bronchoscope and endoscopic baskets.

Results: The patients' ages ranged from 27 to 66 years, with a mean bile duct diameter of 11.6 mm (SD 3.1 mm). A 100% stone clearance rate was achieved for all patients. None of the patients required conversion to open surgery. No T-tubes were placed. One patient developed biloma and intra-abdominal abscesses, which were successfully treated with a percutaneous drain over the course of a week. No mortalities were recorded during the course of this study.

Conclusion: Our study results demonstrate that laparoscopic bile duct exploration is both feasible and safe in patients who have undergone gastric bypass surgery. The utilization of a disposable bronchoscope emerges as a practical and cost-effective alternative to a choledochoscope in this procedure.
