Intestinal malrotation in a patient undergoing laparoscopic gastric bypass.

Intestinal malrotation is an anomalous disorder resulting from the incomplete rotation and fixation of the midgut during embryonic development. Although most patients present early in life with symptoms of bowel obstruction, others remain asymptomatic throughout their lives. We report the case of a 40-year-old morbidly obese woman with no significant past medical history, found to have intestinal malrotation on initial laparoscopic exploration for gastric bypass.
