Gallstone in the gastric remnant after bariatric surgery.

In the last decades, bariatric surgery has been widely performed to treat obesity and its co-morbidities, with the laparoscopic Roux-en-Y gastric bypass (LRYGB) being the second most commonly performed procedure. Abdominal pain after LRYGB is a common symptom. This report concerns a case of a rare cause of chronic abdominal pain after LRYGB and cholecystectomy in a 48-year-old woman due to a cholesterol stone within the gastric remnant that was removed via open gastrectomy. This is the first documented case of cholesterol stone formation in the gastric remnant and underscores the importance of vigilance for atypical complications in patients undergoing bariatric procedures.
