Summary: The study aimed to understand the usefulness of trichloroacetic acid endoscopic application for the treatment of recurrent tracheoesophageal fistula.

Conclusion: Endoscopic management of recurrent transesophageal fistula with trichloroacetic acid is a safe and effective procedure.

Abstract

Background: Surgical repair of recurrent tracheoesophageal fistula has a high risk of complications. Therefore, various endoscopic techniques have been used to avoid complications.

Objective: To understand the usefulness of trichloroacetic acid endoscopic application for the treatment of recurrent tracheoesophageal fistula.

Methods: An observational, descriptive, retrospective, case-series-based study was carried out in a tertiary pediatric hospital. Records of patients with recurrent tracheoesophageal fistula from 2015 to 2021 were reviewed. All patients within this period underwent brushing and trichloroacetic acid application.

Results: Mean time of recurrent tracheoesophageal fistula occurrence was 4.8 months (range: 1-19.2). Two patients had a small fistula (less than 4 mm), three patients had a medium fistula (4 mm), and two patients had a large fistula (more than 4 mm). Mean sessions for fistula closure were 2.2 (range: 1-4). Mean time between procedures was 22 days (range: 14-30). Mean follow-up since fistula closure confirmation was 33 months (range: 9-72), during which no recurrences were noted.

Conclusions: Endoscopic management of recurrent transesophageal fistula with trichloroacetic acid is a safe and effective procedure. Brushing and trichloroacetic acid combined improve success rates. Fistulas over 4 mm in diameter require more procedures. However, a larger patient cohort and a longer follow-up period are needed to confirm this.
