Congenital duodenal adhesions.

Four cases of congenital duodenal adhesions are reported. Primary treatment was the freeing of adhesions, but gastrojejunostomy was also necessary in one patient. The patients have now been followed for from 6 months to 3 1/2 years after operation, and are all well. Diagnois is difficult and can be confused with ulcer. In 2 patients, preoperative differential diagnois included duodenal adhesions, but the other 2 patients underwent laparotomy on the prospective diagnosis of duodenal ulcer.
