Postoperative Fluoroscopic Appearance After Flexible Endoscopic Zenker's Diverticulotomy.

ABSTRACT:

Objective

Flexible approach to treating Zenker's diverticulum (ZD) has gained traction in recent years. However, objective measures comparing pre- and post-surgical outcomes have not been reported. The purpose of this investigation is to describe the changes in quantitative measurements in videofluoroscopic swallowing studies (VFSS) after flexible Zenker's diverticulotomy using modern per oral endoscopic myotomy (Z-POEM) technique.

Methods

A retrospective review of all patients undergoing the Z-POEM technique for treatment of ZD was conducted from July 2022 to December 2024. The primary fluoroscopic outcome measures were the size of the diverticulum, pharyngoesophageal segment opening (PESo) in lateral and anterior-posterior (AP) views, pharyngeal constriction ratio (PCR), a
