Pure esophageal atresia: a 50-year review

Abstract

This review encompasses 50 years (1942 through 1991) and 69 newborns (43 boys, 26 girls). Half the babies were premature (weighing less than 2.5 kg), and about one third had other anomalies. The procedures used in this series were late primary anastomosis (17), gastric tube reconstruction (16), staging esophagostomy and gastrostomy (13), gastric pull-up (13), early primary anastomosis (4), and colon replacement (3). Four neonates received no treatment. The most common repair in the 1940s and 1950s was the gastric pull-up; the gastric tube was the most popular in the 1960s and 1970s. Delayed primary anastomosis has been the operation of choice since the 1980s. Over the last decade, it has become apparent that primary repair is successful in three quarters of such infants if the wait is 3 months and/or the newborn weight has at least doubled. This repair appears to provide the best functional result, unless there is an anastomotic stricture. Before the 1970s, the survival rate was below 40%, but since the 1980s the rate has more than doubled, to 90% in our series, regardless of the type of repair used.
