Congenital intestinal malrotation is a gastrointestinal anomaly whose most serious complication is midgut volvulus. More commonly, it presents as an incidental finding at laparotomy, or as a finding on diagnostic imaging (Ultrasound, CT, Upper GI contrast study). Most patients are diagnosed in childhood. Laparoscopic Ladd's procedure is an accepted alternative to Laparotomy in children but has not been well-studied in adult. We present the case of this unexpected finding in a patient 38 years old, during emergency laparotomy for mechanical intestinal obstruction. Intra-operative findings included intestinal malrotation with small bowel volvulus. The terminal ilea and cecum were gangrenous on the basis of ischemic necrosis. A limited right hemycolectomy and primary end-to- end anastomosis was performed.
