A Rare case of Duodenojejunal Obstruction due to “Fixation Anomaly” in a 5 days old child

A 5 days old male child presented with recurrent bilious vomiting since day 3 of life. Clinically, a diagnosis of malrotation of gut was made and an upper GI contrast study was done. Upper GI contrast study showed complete obstruction at duodenojejunal junction with gross dilatation of the stomach and the duodenum. Patient was subsequently taken for surgery, intraoperatively there was no malrotation, but the obstruction at the duodenojejunal junction was being caused by abnormally narrow and high ligament of Treitz, which was divided and the duodenojejunal junction was freed. Due to the pressure from the ligament of Treitz there was an area of impending perforation at the duodenojejunal junction, so the entire junction was resected and an end-to-end duodenojejunal anastomosis was done.
