duodenoduodenostomy
Pronunciation: /djuːˌoʊdɪnoʊdjuːˈɒdɪnɒstəmi/
Surgical creation of an anastomosis between two portions of the duodenum.
Full Definition
A surgical procedure that creates a direct connection between two segments of the duodenum, typically performed to bypass an obstruction or stenosis in the middle portion of the duodenum. This technique is commonly used in pediatric surgery for conditions like duodenal web or annular pancreas where the obstruction cannot be simply excised. The procedure may be performed as a side-to-side or end-to-side anastomosis depending on the anatomical situation and surgeon preference. Duodenoduodenostomy is often preferred over duodenojejunostomy in neonates because it maintains normal digestive physiology by preserving the natural flow through the duodenum.
Usage
Usage note: Often hyphenated when used as an adjective (duodeno-duodenostomy). Distinguish from duodenojejunostomy, which connects duodenum to jejunum.
