Abstract

Unexpected encounters during surgery for obesity such as midgut malrotation cause specific technical challenges to the surgeon. We present a rare case of asymptomatic complete intestinal malrotation midway during a one anastomosis gastric bypass procedure. A 62-year-old male with a body mass index of 49 kg/m2 and metabolic syndrome was planned for one anastomosis gastric bypass. A gastric tube was created along the lesser curvature. During the attempt to identify the suitable small bowel loop, an unexpected completely malrotated gut was noted. Due to the intraoperative difficulty in identifying the correct loop to anastomose to the gastric tube an intraoperative decision was taken to convert the procedure to a sleeve gastrectomy. The created gastric tube was re-anastamosed to distal stomach, and the redundant stomach was resected. Postoperative recovery was uneventful, and weight loss was satisfactory. Attempted one anastomosis gastric bypass converted to a sleeve gastrectomy was a successful bailout procedure.

Keywords: One anastomosis gastric bypass; bariatric surgery; case report; intestinal malrotation; sleeve gastrectomy.
