Summary
Gallstone formation after laparoscopic Roux-en-Y gastric bypass (LRYGBP) is uncommon. Prophylactic ursodiol shows protective benefits, suggesting a selective approach to cholecystectomy is rational.
Area of Science:
- Bariatric Surgery
- Gastroenterology
- Surgical Outcomes
Background:
- Morbid obesity often necessitates bariatric surgery, with laparoscopic Roux-en-Y gastric bypass (LRYGBP) being a common procedure.
- Cholecystectomy is frequently performed concurrently with gastric bypass surgery.
- The study investigates gallstone development post-LRYGBP.
Purpose of the Study:
- To determine the incidence of gallstone formation requiring cholecystectomy after LRYGBP.
- To evaluate the effectiveness of prophylactic ursodiol in preventing gallstones.
- To assess the role of intra-operative ultrasound (IOUS) and selective cholecystectomy.
Main Methods:
- A cohort of 289 patients undergoing LRYGBP was analyzed.
- Intra-operative ultrasound identified gallstones in 14% of patients, leading to simultaneous cholecystectomy.
- Patients without gallstones received ursodiol and underwent follow-up ultrasound.
Main Results:
- Gallstones were detected in 14% of patients during LRYGBP.
- Postoperative ultrasound revealed gallstones in 22% and sludge in 8% of patients at 6 months.
- Symptomatic gallstones requiring cholecystectomy occurred in 7% of patients; ursodiol compliance was lower in those who developed stones.
Conclusions:
- Symptomatic gallstone incidence after LRYGBP is low.
- Prophylactic ursodiol demonstrates a protective effect against gallstone formation.
- Routine IOUS with selective cholecystectomy and close follow-up is a recommended strategy.
