Abstract
Two case reports are presented of incarcerated small-bowel internal hernias through mesenteric defects following Roux-en-Y gastric bypass surgery (one case each of open and laparoscopic). Both patients first presented to physicians unfamiliar with bariatric surgery complaining of vague, cramping midabdominal pain, and the correct diagnosis was not revealed until laparoscopic surgery was performed. Treatment then resulted in quick recoveries. This type of hernia can evade radiologic testing. Prompt clinical recognition and treatment is necessary to prevent small-bowel infarction.
