Esophageal atresia/tracheoesophageal fistula (EA/TEF) is one of the most common gastrointestinal birth defects. It can occur in isolation or in association with other birth defects or genetic syndromes. We retrospectively reviewed the EA/TEF cases evaluated at Rady Children's Hospital San Diego (San Diego, CA) between 2007 and 2016. Data were collected for 157 patients. The majority of patients (105, 66.8%) had an associated major malformation present, and 52 patients (33.1%) had isolated EA/TEF. The patients with associated malformations were distributed as follows: 16 patients (10.2%) had a known genetic syndrome (the most common being Trisomy 21 in 11 patients); six patients (3.8%) had a suspected genetic syndrome; one patient had a suspected teratogenic syndrome (diabetic embryopathy); 30 patients had VACTERL association (19.1%); 32 patients had a “partial VACTERL” association (only two VACTERL‐type defects without other malformation); nine patients (5.7%) had one additional non‐VACTERL‐type birth defect, two patients had VACTERL‐type defects plus auricular malformations; and nine patients (5.7%) were classified as “unknown syndrome.” A classification of the patterns of malformation of patients with congenital EA/TEF is proposed based on reviewing the data of this relatively large and phenotypically diverse patient group.
