title: [Megaduodenum with non-rotation].
abstract: In a 16-year-old girl who suffered from non-characteristic upper abdominal complaints, the gastrointestinal passage revealed an extreme megaduodenum associated with nonrotation. Intraoperatively, congenital adhesions were found as cause which had stenosed the duodenojejunal transition and had become fixed in the right upper abdomen. After separating the adhesions, resecting the stenosis and narrowing the duodenum, intestinal continuity was restored by means of an end-to side duodenojejunostomy. The causes, signs, diagnosis and therapy of the megaduodenum are discussed.
