Total midgut duplication: a ticking time bomb.

A day-old neonate presented with bowel obstruction and an abdominal mass. Exploratory laparotomy revealed complete tubular midgut duplication from duodeno-jejunal junction up to terminal ileum which was communicating with the ileum distally. At the proximal end, another 5×5 cm duplication cyst was identified and excised. Postoperatively, complaints were relieved. During follow-up, 99m-Tc-pertechnetate-SPECT scan showed ectopic gastric mucosa in lower abdomen and in the right hemithorax. CECT-chest showed a 3×3 cm foregut duplication cyst, but there were no respiratory symptoms. While being planned for an elective surgery, he presented at 6 months of age in emergency with massive bleed per-rectum and shock. He underwent Wrenn procedure without any injury to the normal bowel. The thoracic foregut duplication cyst was excised later. Total midgut duplication, though benign, may present with life-threatening haemorrhage if left untreated. Presence of one such lesion warrants a search for others. Mucosal stripping is a simple and safe alternate to resection.
