A dual H-type tracheoesophageal fistula; why not being repaired simultaneously? A case report and review of literature

H-type Tracheoesophageal Fistula (TEF) is a particular type of congenital esophageal anomalies, in which patients present with non-specific symptoms that can result in delayed diagnosis. Here, we report two pediatric cases with a rarer variant called ‟dual H-type TEFˮ. We present two cases of H-type TEF. The first was a 45-day-old boy with feeding problem and cyanosis while feeding, and the second was a three-month-old girl with cough and choking after feeding from the first day of birth. In both cases, two separate TEFs were detected during diagnostic evaluation by flexible bronchoscopy. Both were repaired simultaneously through a cervical incision. The first patient deteriorated 13 days after the surgery, disturbancing in acid-base balance and expired unfortunately. Hence, it is necessary to consider the possibility of double TEF in any newly diagnosed H-type TEF.
