[Atresia of the esophagus. Experience in 33 patients]. | The authors present their experience in the management of 33 patients with esophageal atresia. Twenty-six of them were type III (fistula from the lower end of the esophagus); four cases were "H" type of fistula and three cases were type one (with no fistula). In the type III group (26 patients) the major associated mal... | 629,837 | [
