“…It increases biliary secretion of cholesterol and decreases gallbladder contractility [180, 181]. Other risk factors for cholelithiasis after surgery for obesity and weight-related diseases include rapid weight loss and the malabsorption that occurs postoperatively.…”

“…Other risk factors for cholelithiasis after surgery for obesity and weight-related diseases include rapid weight loss and the malabsorption that occurs postoperatively. Gallstone formation appears to occur most commonly in the first 6 months following GBP, as documented in a study by Nagem [180]. The debate regarding routine versus selective cholecystectomy has been extensively studied in patients undergoing GBP, but there is limited data for patients undergoing LAGB, SG, and BPD [182].…”

Risk of Biliary Events After Selective Cholecystectomy During Biliopancreatic Diversion with Duodenal Switch

“…A study of the natural history of cholelithiasis in general population demonstrates that approximately 35 % of patients who are initially diagnosed with cholelithiasis, but not treated, will later develop symptoms or biliary complications leading to cholecystectomy in their lifetime [1]. This suggests that cholelithiasis can Obesity is a risk factor for cholelithiasis by increasing biliary secretion of cholesterol [8] and decreasing gallbladder contractility [9]. Other risk factors in bariatric patients include rapid weight loss and malabsorption that occur postoperatively.…”

Perioperative Care of the Surgical Patient

“…Gallstones can develop in 28 % of patients after bariatric surgery [138,139]. Patients who presented with right upper quadrant abdominal pain should have imaging test with an ultrasound.…”
