HYPERTROPHIC PYLORIC STENOSIS COMPLICATING ESOPHAGEAL ATRESIA WITH TRACHEOESOPHAGEAL FISTULA

Four patients with esophageal atresia and tracheoesophageal fistula are reported in whom hypertrophic pyloric stenosis developed in the postoperative period. The presence of hypertrophic pyloric stenosis is often obscured because the symptom of vomiting secondary to pyloric stenosis appears in the postoperative period and may be attributed to a complication of the esophageal surgery. Hypertrophic pyloric stenosis should be considered in the evaluation of vomiting in the infant after repair of tracheoesophageal fistula and appropriate roentgenographic studies should be obtained. © 1969.
