Comparison of cholecystectomy cases after Roux-en-Y gastric bypass, sleeve gastrectomy, and gastric banding

EASL Clinical Practice Guidelines on the prevention, diagnosis and treatment of gallstones

“…Cholecystectomy is indicated in up to one-third of patients by 3 years after surgery [27,150]. After bariatric surgery, the risk of developing gallstone disease increases to 48% for weight loss greater than 25% of original weight, especially after gastric bypass or sleeve gastrectomy [157][158][159][160][161][162]. The same trend is observed in obese patients using hypocaloric diets postoperatively [137].…”

Laparoscopic Adjustable Gastric Banding in Australian Adolescents: Should It Be Done?

“…In addition to band removal, one late morbidity leading to reoperation in our cohort was related to symptomatic gall stone formation which is known to be related to weight loss and has been previously described in adults and adolescents [13,22,23].…”

A Retrospective 2-Year Follow-up of Late Complications Treated Surgically and Endoscopically After Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) and Laparoscopic Sleeve Gastrectomy (LSG) for Morbid Obesity

“…Known risk factors for biliary complications after bariatric surgery, including acute and chronic cholecystitis, acute pancreatitis, and choledocholithiasis, are rapid weight loss, age greater than 50, female gender, cholelithiasis at time of bariatric procedure, and RYGB operation [26]. Moon et al compared the incidences of symptomatic gallstone formation and cholecystectomy after LRYGB and LSG operations for a mean of 2 years after the operations, finding no significant difference between the two operation types [27].…”
