Acute Abdominal Pain after Roux-en-Y Gastric Bypass
An internal hernia is one of the most frequent complications after Roux-en-Y Gastric Bypass (RYGB) surgery and is defined as a herniation of the small bowel through a mesenteric defect. Internal hernia through a mesenteric defect can lead to small bowel obstruction.
