Duodenal obstruction secondary to congenital web in an adult.

Congenital duodenal web, although rare, may be more common than presently appreciated. The possibility of this condition should be considered in the differential diagnosis of duodenal obstruction in the adult. It should be treated surgically either by duodenotomy with excision of the web or by duodenojejunostomy. The results are excellent, as illustrated by the authors in their report of a 58-year-old man with this condition, who was treated by duodenojejunostomy.
