Congenital intestinal malrotation occurs in 1 of 500 newborns and can predispose patients to intestinal volvulus and internal herniation, putting patients at risk for intestinal ischaemia. A male patient in early childhood with a history of severe constipation presented with acute abdominal pain, progressing rapidly to compensated shock. CT scan was suspicious for small bowel ischaemia and superior mesenteric artery compression. He underwent emergency exploratory laparotomy. Intraoperative findings were significant for partial intestinal malrotation with mobile ascending colon and high-riding caecum, and internal herniation with midgut volvulus of the ascending colon through a mesenteric defect in the proximal transverse colon. Derotation of the volvulus, reduction of the internal hernia, resection of necrotic segments of the bowel and a modified Ladd’s procedure were performed. Postoperatively, the patient is total parenteral nutrition (TPN) dependent due to short bowel syndrome. A high index of suspicion with prompt imaging is paramount for paediatric patients with symptoms indicating intestinal obstruction.
