Membranous atresia of esophagus associated with pyloric stenosis

Membranous atresia of the esophagus without tracheoesophageal fistula (TEF) is very rare, only four cases have been reported since 1928. We present a case in whom a thick membrane was present 2 cm proximal to the diaphragm. The membrane was resected and the longitudinal esophagotomy wound was closed transversely. The postoperative course was complicated with hyperbilirubinemia and hypertrophc pyloric stenosis (HPS). The problems of the feeding tube used for diagnostic evaluation of this rare esophageal anomaly are discussed. In spite of its low incidence, the potentiality of HPS as a cause of postoperative vomiting in esophageal atresia should be borne in mind in order to avoid delay in diagnosis.
