Redo Laparoscopic Gastric Bypass in a Patient with Intestinal Malrotation: Report of a Case and Video Vignette

Ingeborg Bohlmann et al. Obes Surg. 2023 Aug.

Abstract

Unknown intestinal rotation anomaly poses a challenge in laparoscopic gastric bypass surgery. We present a case of a patient with intestinal non-rotation that stayed undetected throughout performing a laparoscopic Roux-en-Y gastric bypass. As a result, the alimentary limb was constructed in an anti-peristaltic way, and the whole gastric bypass was located far more distally than usual. Postoperatively, the patient presented with recurring nausea and vomiting. After several diagnostic steps, a computed tomography finally revealed the inadvertently reverse directed gastric bypass and the pre-existing condition of intestinal non-rotation. This was followed by a diagnostic laparoscopy and the reconstruction of the gastric bypass in "mirrored" technique.
