Congenital duodenal obstruction

Abstract Congenital duodenal obstruction occurs as a result of a number of conditions, culminating in feeding intolerance and emesis in the newborn. The most common causes include duodenal atresia, annular pancreas, duodenal web, and Ladd’s bands. It is commonly associated with congenital heart disease and trisomy 21. Urgent diagnosis and management are necessary, especially in cases associated with malrotation. The hallmark of management consists of operative exploration in the first 24–48 hours of life with duodenoduodenostomy, bypassing the site of obstruction. Perioperative mortality is low and generally related to associated anomalies, but long-term gastrointestinal consequences, some requiring reoperation, are not uncommon.
