Abstract

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a foregut defect that is a major component of the VATER/VACTERL association. The specific diagnostic criteria for the VATER/VACTERL association phenotype have changed over time. The current definition is presence of at least three of the following: Vertebral defects, Anal atresia, Cardiac defects, TE fistula, or Renal and Limb anomalies in the absence of a specific genetic diagnosis. Using the Texas Birth Defect Registry, 1,175 cases of EA+/−TEF (174 EA; 1,001 EA + TEF) were evaluated against strict definitions of VATER/VACTERL. Nine (5.2%) cases of EA alone and 164 (16.3%) cases of EA + TEF met criteria for a diagnosis of VATER; and 20 (11.5%) and 223 (22.2%), respectively, met criteria for VACTERL. Trisomy 21, Trisomy 18, 22q11 deletion, and CHARGE were the most common syndromic diagnoses. About 88.5% (154) cases of EA and 77.8% (778) cases of EA + TEF were likely not to meet the criteria for VACTERL. EA+/−TEF is more likely to be an isolated defect or part of a multiple malformation syndrome in a pattern other than VACTERL, than be part of the defined association. This study reinforces the need to consider broader evaluation for alternate diagnoses in the presence of these defects.
