Atretic, obstructive proximal duodenal mass associated with annular pancreas and malrotation in a newborn male.

A case is described of duodenal atresia involving the first portion of the duodenum associated with a partial annular pancreas, complete nonrotation and nonfixation of the intestines, and a congenitally small glottic region in a newborn male. The atretic segment was a 1.3 cm mass adjacent to the pylorus unlike previous reports of duodenal atresia. The diagnosis was delayed for seven days until the child was fed and had bowel movements. Pyloroduodenostomy was performed resulting in cure. An older sibling had a duodenal web requiring previous duodenoduodenostomy.
