Combined hypertrophic pyloric stenosis and duodenal web in Down syndrome: sonographic and radiographic diagnosis.

Abstract

Gastrointestinal anomalies associated with Down syndrome have been recognized for a long time. Major anomalies reported include duodenal atresia or stenosis, annular pancreas, gastroesophageal reflux, imperforate anus, Hirschsprung disease, malrotation, bile duct atresia, esophageal atresia or tracheoesophageal fistula, and HPS. 1-3 We report the clinical and imaging features of a combination of HPS and a duodenal web in a 2 month old boy with Down syndrome.
