Highlights
•
Treatment of symptomatic Zenker's diverticulum is mainly via endoscopic transoral approaches.
•
Several advanced energy devices have been used for endoscopic treatment of Zenker's diverticulum.
•
The use of the Enseal device for rigid transoral Zenker's diverticulotomy has not been studied.
Abstract
Objectives
The objective of this study is to analyze and report the institution's experience using the Enseal bipolar tissue sealing device to perform endoscopic Zenker's diverticulotomy. Safety and early functional outcomes are presented as primary endpoints of the study.
Materials & methods
This is a retrospective study of consecutive patients with Zenker's diverticulum (ZD) treated via a transoral approach using a rigid endoscope and a bipolar tissue sealer between 2011 and 2019. Demographic data, ZD size, complications and preoperative versus postoperative symptoms were assessed. The Eating Assessment Tool-10 (EAT-10) questionnaire was used to evaluate functional outcomes, and statistical comparisons were made using the student's t-test.
Results
Nineteen ZD patients were identified who underwent rigid endoscopic diverticulotomy using a bipolar tissue sealer. The mean age was 71 years and 74% were male. The mean diverticulum size was 3.1 cm. There were no intraoperative or postoperative complications identified. Average pre-operative EAT-10 score was 21 and post-operative EAT-10 score was 12 at one to two weeks after surgery (p = .05).
Conclusions
Evidence from this preliminary study of endoscopic Zenker's diverticulotomy using the Enseal device indicates that it is both safe and effective. Several features of the device, including its narrow profile, articulation and rotation capability, rapid repeatable activation, and low risk of collateral thermal injury, make it an appealing option for endoscopic Zenker's diverticulotomy.
