RESUMO
Esophageal atresia with distal tracheoesophageal fistula has been treated at one institution between 1951 and 1983 primarily by prompt transpleural repair without gastrostomy. Two hundred and seventy one patients are assigned to three time periods: (1) 1951 to 1963, prior to modern intensive care; (2) 1964 to 1973, the initial era of mechanical ventilation; and 1974 to 1983, the era of readily available ventilators and TPN. During these time periods mean birthweight decreased from 2,780 g to 2,670 g to 2,500 g, while the incidence of associated anomalies increased from 41% to 44% to 55%. Eleven patients had no operation or gastrostomy only and died. Twenty (predominantly in the early years) had staged repairs with initial gastrostomy and fistula ligation. Primary anastomosis was done in 240 patients regardless of birth weight, 229 of which were by the transpleural approach. Gastrostomy was performed primarily in 28 patients for varied indications. Operative mortality (definitive as well as staged repairs) fell over the three time periods from 44% to 15% to 7%. Anastomotic leaks occurred in 20% of patients who underwent primary repair regardless of the time period. The mortality associated with a leak, however, decreased from 88% to 47% to 0%. Anastomotic strictures requiring more than two dilatations occurred in 15% in all periods. The overall incidence of recurrent fistula was 5%. Of 200 patients surviving the initial hospitalization, follow-up longer than 2 months is available for 156 patients with a median follow-up of 30 months. There were 15 late deaths.(ABSTRACT TRUNCATED AT 250 WORDS)
