Congenital Duodenal Obstruction: Etiology, Clinical Presentation, and Diagnostic Approaches

Abstract

Congenital duodenal obstruction (CDO), that is, duodenal atresia or stenosis, is a rare congenital anomaly that requires surgical correction in childhood. It is usually characterized by early vomiting due to high intestinal obstruction. Presentation of congenital duodenal obstruction with acute gastrointestinal bleeding, although rare, can also occur. There are several causes of congenital duodenal obstruction, most of which require elective surgical correction; however, if there is a possibility of intestinal malrotation and midgut volvulus, imaging evaluation is necessary.
