Abstract

Background

Flexible endoscopy allows use of the vessel–tissue sealer Ligasure™ (Covidien, Massachusetts, USA) to perform diverticulotomy. Few studies have used this endoscopic approach in the uncommon disorder Zenker's diverticulum. The aim of the present study was to evaluate the effectiveness and safety of flexible endoscopy treatment assisted by Ligasure™.

Methods

The single-center prospective and descriptive study included patients treated by flexible endoscopy using Ligasure™ for resection of Zenker’s diverticulum. Consecutive patients were included from March 2009 to April 2018. Patients were censored until the end of follow-up or death. Complications, symptoms before treatment, type of sedation, and number of interventions needed to resolve Zenker’s diverticulum were analyzed. Bleeding complications were considered when a case required a second endoscopy.

Results

A total of 46 symptomatic patients with Zenker's diverticulum were included in the final analysis (41.3% women, median age of 73.7 ± 11 years). The median follow-up period was 37.21 ± 28 months. Of all cases, 58.7% were considered small (< 3 cm). Solid or semi-solid food-related dysphagia was present in 55.6% of patients previously to the procedure. The technique was successful in a single procedure in 78.3% of cases. However, the success rate increased to 89.1% with a second procedure, and we had a complication rate of 4.3% with this technique. Most patients (79.66%) were managed as out-patients or with short (< 24 h) admission.

Conclusion

In this large case series, treatment of Zenker's diverticulum based on flexible endoscopy assisted by Ligasure™ was a safe and effective procedure with a high success rate in a few endoscopy sessions and low complication rate.
