Esophageal Atresia with Distal Tracheoesophageal Fistula in Both Members of Monozygotic Twins

ABSTRACT

Although the incidence of esophageal atresia (EA) is higher in twins than in singletons by two to three times, EA usually affects only one member of twins. We report one pair of twins concordant for EA. A 31-year-old healthy woman bore monozygotic female twins at 36 weeks of gestation. They weighed 2,216 and 2,480g, respectively. They had EA with distal tracheoesophageal fistula and underwent primary esophageal anastomosis on the birth day and the 2nd day of life, respectively. Twin A also had suspicious antral obstruction and pyloroplasty was done simultaneously with esophageal repair. She needed antral web excision for continued gastric stasis one month after 1st operation and three balloon dilatations of the esophagus. Twin B recovered uneventfully.
