RESUMEN
Objective To explore the diagnosis and treatment of the congenital membrane atresia of duodenum(CMAD). Methods The clinical data of 32 cases of CMAD admitted from 1980 to 1996 were analysed retrospectively.Results Of the 32 cases,28 cases had single membrane in the duodenum,4 two membranes;and 6 accompanied with intestinal malrotation, 2 circular pancrease and 1 anal atresia. 24 patients were treated with membrane resection only,2 underwent membrane resection and gastrojejunostomy,6 underwent membrane resection plus Ladd's operation.28 cases were cured,4 cases died.Among the 28 cases discharged,20 cases were followed-up for the period from five months to three years,their sympotoms disappeared, nutrition and development were good.Conclusions Patients with CMAD have vomit, and containing bile in most cases;abdominal erect plain film shows "double bubble sign",and gastrointestinal series can help make the diagnosis.Membrane resection is the best way of therapy,but we should pay attention to correct the double membranes and other deformity,and should strengthen perioperative period management.
