Comparison of diagnostic methods, surgical approaches and outcome for congenital H-type tracheoesophageal fistula: A Systematic Review

jpedsurg.org

Congenital H-type tracheoesophageal fistula (H-TEF) is a rare congenital defect characterized by an abnormal connection between the trachea and the esophagus. It occurs in approximately one in 50,000 live births (1). Diagnosis can be difficult and delayed in H-TEF because of the absence of an associated atresia of the esophagus. Symptoms are usually nonspecific. Recurrent pneumonia, chronic cough, and dysphagia may yield to further investigations for a definitive diagnosis (2, 3). A delayed diagnosis could alter the size and position of the fistula anatomy in relation to organs, thereby limiting therapeutic options.

In brief

This systematic review examines diagnostic approaches, surgical techniques, and outcomes for H-type tracheoesophageal fistula, a rare congenital defect affecting 1 in 50,000 births. The review addresses diagnostic challenges due to nonspecific symptoms and explores how delayed diagnosis impacts treatment options and anatomical considerations for surgical repair.

H-type TEF occurs in ~1:50,000 live births and lacks esophageal atresia, making diagnosis challenging and often delayed.
Classic presentation includes recurrent pneumonia, chronic cough, and dysphagia—maintain high clinical suspicion.
Delayed diagnosis can alter fistula anatomy and position, potentially limiting surgical treatment options.
Definitive diagnosis requires targeted imaging after initial nonspecific symptoms prompt further investigation.
Early recognition is critical: anatomical changes from delayed diagnosis may complicate surgical repair.
