The twin with esophageal atresia

A retrospective analysis of esophageal atresia occurring in patients who are members of a twin set indicated that twinning does occur more frequently in patients with esophageal atresia. These patients tend to be small for date, but have a similar occurrence of associated anomalies as singletons with esophageal atresia. Applying risk-grouping to the entire series and twins indicated no real difference in survival or additional anomalies by organ system, except more cardiovascular anomalies occurred in twins. Long-term follow-up of five survivors revealed severe growth retardation.
