Acute Pouch Outlet Obstruction Due to Lactobezoar after Roux-en-Y Gastric Bypass

Lactose intolerance is not infrequent among people of Asian descent, and soy milk is a preferred substitute to dairy in many Asian countries. [1]. A 32-year-old woman with morbid obesity (initial body mass index: 47.9 kg/m2) and past history of lactose intolerance presented to our Emergency Department with intractable belching and vomiting after consuming 300 mL of concentrated soy milk. She had just underwent an uneventful laparoscopic Roux-en-Y gastric bypass (antegastric, antecolic gastrojejunostomy), and was discharged two days prior to re-admission with a two day hospital stay after initial surgery.
