ABSTRACTIntroduction. Intestinal atresia is the most common cause of complete obstruction in newborns; it is present in 1 of 15 to 20 thousand born alive children. Anomalies of the small intestine constitute 95% of the cases. Colon atresia is a rare condition. Diagnosis must be done with colon by enema.
Case report. Newborn boy with a history of polyhydraminios who presented with gastrobilliar vomit the first day of life; abdominal distension and intestinal loop drawings. Abdomen X ray showed bowel loops distension, diminished air-fluid levels and distal pneumatization. A colon by enema showed a microcolon and obstruction in the hepatic angle. A laparotomy confirmed colon atresia in the splenic angle with a mesenteric “V” shape defect.
Discussion. A history of polyhydramnios should lead to suspect intestinal malformations; gastrobilliar vomit suggests an intestinal obstruction usually of the small intestine. Radiologic images confirm the diagnosis; the colon by enema is the only study that shows the obstruction.
