简要总结
The Zenker's or pharyngo-esophageal diverticulum is an acquired sac-like outpouching of the mucosa and submucosa layers located dorsally at the pharyngoesophageal junction through Killian's dehiscence. It is the most common type of oesophageal diverticula and typically occurs in middle-aged and elderly patients. Patients have a significantly reduced quality of life index and numerous complications.
Treatment is recommended for symptomatic patients and considering the aetiopathogenesis of the disease demands myotomy of the cricopharyngeal muscle. Myotomy may be pursued through either open surgical or endoscopic techniques.
There is a novel technique, called the peroral endoscopic myotomy (Z-POEM) for treatment of Zenker's diverticulum.
The ZIPPY trial designed as prospective, international, multicenter, double-blind, randomized study which will be carried out by experienced endoscopists. The aim of this study will be to evaluate the results of Zenker's diverticulum treatment using peroral endoscopic myotomy and to compare its efficacy and safety to flexible endoscopy septotomy. Patients at least 18 years old with symptomatic Zenker's diverticulum diagnosed on the basis of endoscopic and radiological examinations will be enrolled.
详细描述
Participants will be randomized into one of two groups: (I) Z-POEM, (II) flexible endoscopic septotomy. Patients with clinical failure will be offered other method of treatment and will be included to observational cohort. The study has been approved by a local bioethics committee
