Abstract
Gastroesphageal reflux (GER) occurs frequently in infants with esophageal atresia (EA). The definitive management is primary repair and often includes tube gastrostomy. The recent finding of lower esophageal sphincter (LES) pressure changes with tube gastrostomy suggests that GER might be related to gastrostomy rather than EA per se. To evaluate this thesis, two populations of patients from different children's hospitals were reviewed: EA with and without routine gastrostomy. The two populations were similar with respect to number of infants, associated anomalies, distribution in the Waterston classification, morbidity, and mortality. One hundred sixteen patients were studied. Of the 66 survivors who underwent gastrostomy and repair of EA, 30 were found to have GER (45.5%) and 12 required fundoplication (18.2%). Of 31 surviving patients who underwent repair of EA without gastrostomy, 11 had GER (35.5%) and four required fundoplication (12.9%). These data suggest that tube gastrostomy does not significantly contribute to the GER associated with EA.
