Objective: To review our management of intestinal atresia (AI).

Methods: A retrospective review of patientes with AI, from 1995 to 2011.

Results: AI was identified in 41 patients, 29,2% had maternal polyhydramnios and 48,7% were diagnosed prenatally. Four of them had Down Syndrome and 18 had cardiopathy. Duodenal atresia-stenosis (AD) was present in 21 patients, that were treated by 19 duodenoduodenostomy, 1 duodenojejunostomy and 1 duodenotomy with duodenal membrane resection. Jejunoileal atresia (AYI) was present in 20 patients and we performed 15 end to end anastomosis, 1 íleo-colic anastomosis, 1 ileostomy, 2 jejunostomies and 1 end to end anastomosis with jejunostomy. Nine AYI were reoperated: 6 bowel obstructions, 1 evisceration and 2 colo-rectal atresia. The average time on parenteral nutrition was 29 days and average hospital stay was 37,3 days. One AD died due to heart disease. In AYI, 2 required transfer to another center due to short bowel.

Conclusions: Prenatal diagnosis of AI is difficult, especially AYI, which is only prenatally diagnosed in 35% of cases. AD respond better to surgery and rarely require reoperation, but mortality is higher than AYI because 57% suffer from heart disease. Reoperations are frecuent in AYI (45% of our patients), usually due to obstruction, ostomy closure and problems resulting from extensive bowel resections. It's important to keep in mind colorectal atresias, which can not be identified.
