Management of Zenker's diverticulum using flexible endoscopy.

BACKGROUND AND AIMS: Zenker's diverticulum is a false diverticulum through Killian's dehiscence. Symptoms include halitosis, dysphagia, regurgitation, cough, and aspiration pneumonia. Treatment options include open transcervical cricopharyngeal myotomy, trans-oral rigid endoscopic stapling, and minimally invasive endoscopic myotomy. Although open surgical techniques have historically been the criterion standard for treatment, endoscopic options have become increasingly used. We propose the use of flexible endoscopy in the management of Zenker's diverticulum.

METHODS

We present a retrospective case series of 9 patients undergoing endoscopic cricopharyngeal myotomy from 2014 to 2018 using our endoscopic technique.

RESULTS

We demonstrate that endoscopic technique provided adequate symptomatic relief in 7 of 9 patients, with no operative adverse events.

CONCLUSIONS

Cricopharyngeal myotomy using flexible endoscopy is a safe and effective technique for the management of Zenker's diverticulum. Potential benefits of this approach include shorter operative times, shorter postoperative admissions, and earlier progression of diet. Initial treatment with endoscopic technique does not preclude future open repairs.
