Thoracoscopic Repair for Kluth Type Ⅲb3 Esophageal Atresia and Distal Tracheoesophageal Fistula.

INTRODUCTION

This report aims to present our initial miniseries of successful thoracoscopic repair for esophageal atresia (EA) and distal tracheoesophageal fistula (TEF) of Kluth type Ⅲb3 in accordance with Kluth's classification.

METHODS

From January 2012 to January 2024, ten patients with Kluth type Ⅲb3 EA-TEF were treated by thoracoscopic surgery. The therapeutic methods and surgical outcomes were retrospectively reviewed.

RESULTS

All procedures were completed thoracoscopically without conversions. A preoperative bronchoscopy assessment was conducted in four of the cases, revealing that the fistula from the distal segment was located high on the trachea at the level of T2 vertebral. The mean age of the patients at the time of operation was 2.0 ± 0.7 d (range, 1-3 d), and the mean weight at operation was 2.6 ± 0.4 kg (range, 1.8-3.0 kg). The mean operative time (skin to skin) for the entire series was 137.0 ± 8.9 min (range, 120-150 min). Oral feeding was initiated on the postoperative day 8.0 ± 1.9 (range, 6-12 d), and the mean duration for patients after surgery was 14.0 ± 2.4 d (range, 12-20 d). The postoperative period has been uneventful with no occurrences of mortality or morbidity to date. Three cases of formatted anastomotic stricture required at least one esophageal dilation after surgery.

CONCLUSIONS

Pediatric surgeons should be aware of the rare variants of EA-TEF to avoid the diagnostic and management pitfalls. Patients with Kluth type Ⅲb3 EA-TEF were amenable to repair by thoracoscopic surgery.
