[Congenital atresia and stenosis of the intestine].

During the period between 1946 and 1996, 59 patients of intrinsic duodenal obstruction and 67 of intrinsic jejunoileal obstruction were treated in our institute. Analysis of data obtained from the patients revealed that the duodenal obstruction was the most successfully treated by diamond-shaped duodenoduodenostomy, jejunal obstruction by resection of the dilated oral blind end, tapering jejunoplasty and ileal obstruction by resection of the dilated blind end and anastomosis or ileostomy in case with peritonitis. Associated anomalies in duodenal obstruction, anastomotic malfunction and postoperative short bowel syndrome in jejunal obstruction and complicated peritonitis in ileal obstruction were the most effective as prognostic factors.
