[Malformations associated with esophageal atresia].

Associated malformations present in 277 newborn patients operated during the last sixteen years for esophageal atresia and tracheoesophageal fistula are described. Incidence on concomitant anomalies of each organ system is compared to that published by various authors during this period of time. Mortality, as related to each organ system and to the patient classification according to Waterston risk-groups, is studied during two different periods (1965-1975 and 1976-1981) considering in the second one a significant improvement of pre and postoperative care.
