Circular esophagomyotomy for primary repair of long-gap esophageal atresia

Abstract

Twelve of forty patients (30%) treated for esophageal atresia at the Children's Memorial Hospital in Chicago between June 1976 and May 1980 required a circular esophagomyotomy with or without upper pouch bougienage to achieve an anatomical repair. Ten patients had a distal tracheoesophageal fistula; 1 had a proximal fistula as well; and 2 had no fistula. Over 40% of the patients were small for gestational age. One half had severe associated anomalies including congenital heart disease in 1/3 and the VATER association in 1/4. Three patients died, all from congenital heart disease. Immediate complications in 6 patients included anastomotic leaks (3), tracheal injuries (2), and mucosal entry at the myotomy site (1). Late complications included symptomatic gastroesophageal reflux (60%), anastomotic strictures (40%), and severe tracheomalacia requiring long-term tracheotomy (20%). Altered esophageal motility (77%) contributed to poor weight gain (less than 3rd percentile) in most patients. In spite of these complications, satisfactory results were achieved in 8 of the 9 long-term survivors. The ninth patient had a turbulent neonatal period and has persistent swallowing difficulties at 36 mo follow-up. Although an anatomical repair can now be achieved in all patients with esophageal atresia utilizing bougienage and myotomy, some ill neonates may be better served by traditional staging techniques.
