Definition and Background
EA is defined as a complete interruption in the continuity of the esophageal lumen.2 TEF may be defined as a congenital, fistulous connection between the proximal and/or distal esophagus, and the airway.3 While EA and TEF may exist as separate congenital anomalies, the great majority of patients with these congenital malformations have both EA and TEF. As EA, TEF, and EA/TEF generally have similar associations with other anomalies and complications, they will be considered together in this
Embryology
The median pharyngeal groove develops in the ventral aspect of foregut at day 22 of gestation. This tissue develops into the respiratory and digestive tubes. Normally, mesenchyme proliferating between the respiratory and digestive tubes separates the tubes. While several theories have attempted to explain the etiology of EA/TEF, it is currently believed that the development of an abnormal epithelial-lined connection between the two tubes results in the creation of a TEF.1 The excess tissue
Classification
There are five types of congenital EA/TEF (Fig 1). Two similar classification systems, the Gross and the Vogt classification systems, are in use.1718 Gross type C (Vogt type 3B) EA/TEF, which consists of distal TEF with proximal EA, is the most common type, comprising approximately 88.5% of cases. Gross type A, or isolated EA, occurs in approximately 8% of cases. Gross type E EA/TEF, consisting of TEF without EA, or H-type TEF, occurs in approximately 4% of cases, with the remainder consisting
Surgical Management
Most infants with EA/TEF undergo repair in early infancy, with division of the TEF and primary esophageal anastomosis. Patients with EA and wide separation of the esophageal ends continue to represent a major surgical challenge. Lengthening procedures, with or without esophagomyotomy, may be used to allow esophageal anastomosis. Neonatal esophageal stretching has been reported to allow primary anastomosis of the esophagus even in infants with long-gap EA/TEF.19 In more severe cases, anastomosis
Growth
GI symptoms are common in children with a history of EA/TEF.23 Weight and height percentiles of children with EA/TEF may be reduced compared to sibling pairs, although some studies2324 have reported normal growth.
Anastomotic Leak
Anastomotic leak is an uncommon early complication of surgical repair, occurring in up to 17% of patients. However, it has potentially significant long-term consequences.1 While 95% resolve spontaneously or with pleural drainage, esophageal stricture follow in 50% of cases. They can be
Respiratory Complications of EA/TEF
Respiratory symptoms are common in patients with repaired EA/TEF. In one series,16 46% of patients with EA/TEF (99% of whom had a type C EA/TEF) had respiratory complications, with 19% of patients having recurrent pneumonia, 10% having aspiration, and 13% had choking, gagging, or cyanosis, with feeds. Respiratory complications were due to GERD in 74% of cases, tracheomalacia in 13%, recurrent TEF in 13%, and esophageal stricture in 10%, although many patients had multiple causes.16 In another
Summary
Serious respiratory and GI complications, such as recurrent pneumonia, obstructive airway disease, airway hyperreactivity, GERD, and esophageal stenosis, are frequent in patients with a history of EA/TEF, although the frequency of such events appears to decrease quite significantly with age.252728363960 Respiratory and GI sequelae in patients with a history of EA/TEF result from a complex interplay of numerous potential complications, and some complications can exacerbate others.
