Aim This study presents a single institutional experience with H-type tracheoesophageal fistula (H-TEF). Methods Esophageal atresia (EA) patients who underwent primary surgery in a single center between 2006 and 2018 were retrospectively evaluated. Results Among 110 EA patients, 7 (6.4%) had H-TEF. There were 5 males and 2 females. The primary complaints were choking, cyanosis, and/or apnea with feeding, swallowing difficulty, recurrent bronchopneumonia, or bile in endotracheal tube. The relevant symptoms began during neonatal period with varying degrees of severity in all. The initial diagnosis was proximal esophageal web as demonstrated by contrast swallow and endoscopy in one patient; H-TEF was diagnosed during the course of treatment for the web. Hydrocephalus with severe neurological sequela unrelated to H-TEF and cardiac malformation were present in one. Contrast esophagography was employed in three patients for diagnosis two of which were diagnostic. All underwent diagnostic bronchoscopy. Delayed diagnosis (after 30 days of life) occurred in five (71%). The median age at operation was 3.8 months (11 days–33 months). The level of the fistulas was between C5 and T3. Preoperative bronchoscopic cannulation was successful in all but one. The operation was done via a right cervical approach in six patients and thoracotomy in one. All patients were followed up for at least one year and there was one recurrence detected five months after the first operation. She underwent a secondary surgery with a successful outcome. Right vocal cord paralysis was detected postoperatively in the patient with hydrocephalus. Conclusions H-TEF is a rare subtype of EA malformations with a delay in diagnosis in most cases. Suggestive clinical findings, especially neonatal respiratory symptoms should always be regarded as an indication for further investigations. Although contrast esophagograms may reveal the diagnosis, bronchoscopy is the gold standard diagnostic test in our practice. It should be done preoperatively in every patient not only for diagnostic confirmation but also for cannulation of the fistula to ease the operation. H-TEF might be considered a relatively innocent EA variant but its surgery is not devoid of complications. The patients should be followed up for recurrence and recurrent laryngeal nerve injury on the long term.

Congenital esophageal stenosis (CES) is a rare congenital disorder which may be isolated or associated with esophageal atresia (EA). It courses with esophageal outflow tract obstruction. Esophageal epiphrenic diverticulae are esophageal outpouchings above diaphragm which develop because of an underlying esophageal motor disorder. We present an infant who had CES associated with EA detected during the course of routine follow-up. She underwent several sessions of esophageal balloon dilatations for CES with some symptomatic improvement. However, an epiphrenic diverticulum (ED) developed during the course of treatment which was detected by further investigations. A surgical excision was performed with a successful outcome. An ED developed secondary to CES has not been previously reported. We have highlighted the diagnostic modalities employed, treatment options, and clinical follow-up for these two rare conditions in children.

Background: Oesophageal dilatations can be done either by bougies or balloons for differing aetiologies in children. We investigated the efficacy and safety of endoscopic balloon dilatations (EBDs) employed by a single surgeon. Patients and Methods: Relevant data over 12 years were retrospectively evaluated with an ethical committee approval. Results: Ninety-seven children underwent 514 EBD with a median EBD of 3 (1–50). The primary diagnoses were oesophageal atresia (OA) in 51 children, corrosive ingestion in 21, peptic strictures in 13, achalasia in 8 and congenital oesophageal stenosis in 4. The balloon size varied between 3 and 30 mm. The EBD was successfully ended in 72 patients and unsuccessful in six patients. Six children are still under EBD and 13 are lost to follow-up. The overall success rate was 92%. The age at the time of first dilatation was the youngest in OA group followed by corrosive strictures. The balloon sizes differed regarding the age of the patients with larger balloons used as the patient age increased. The sizes of the balloons used at the first and the last EBD differed among diagnostic groups. The total number of dilatations or the time interval between the first and the last EBD dilatation did not show a statistically significant difference among groups. The anatomical type of OA or the height of corrosive stricture revealed no significant difference in any of the above parameters. A transmural oesophageal perforation occurred during 2 (0.4%) EBD sessions. Conclusions: EBD is an effective mean in relieving paediatric oesophageal pathologies with a variety of aetiologies and has a low complication rate.
