Tapering duodenoplasty and gastrojejunostomy in the management of idiopathic megaduodenum in children

Idiopathic megaduodenum without organic obstruction is a rare clinical condition. Massive dilatation confined to the duodenum was shown by upper gastrointestinal contrast studies and ultrasonography and can also be identified on antenatal ultrasonography. In children with megaduodenum, satisfactory results can be obtained by tapering duodenoplasty with proximal stump closure and gastrojejunostomy with either Roux-en-Y or end-to-side anastomosis.
