No pouch, no problem: successful endoscopic division of a symptomatic cricopharyngeal bar using a modified peroral endoscopic myotomy technique for Zenker’s diverticulum
Cricopharyngeal bars (CPBs) are fibrous thickenings of the cricopharyngeus (CP) muscle that can rarely lead to dysphagia. Established treatment modalities include esophageal dilation, endoscopic botulinum toxin injection, and surgical cricopharyngeal myotomy. There has been no reported experience with peroral endoscopic myotomy (POEM) for symptomatic CPBs.Functional luminal imaging probe technology to assess response after flexible endoscopic Zenker diverticulotomy
Zenker diverticulum (ZD) is rare, with an unknown overall prevalence, given that many patients with ZD are likely asymptomatic.1 ZDs are pseudodiverticula that manifest as mucosal and submucosal pulsion through the Killian triangle. Postulated mechanisms include increased intraesophageal pressure at an area of weakness in the proximal esophageal wall and hypertensive upper-esophageal sphincter (ie, decreased compliance). ZD is frequently diagnosed by esophagography. Symptoms include dysphagia, regurgitation, and, in severe cases, weight loss and malnutrition.Difficult intubation of a Zenker's diverticulum with an acute angle
A 94-year-old woman was referred because of oropharyngeal dysphagia and previously failed intubation. A barium swallow had revealed Zenker’s diverticulum (ZD) and cricopharyngeal hypertrophy (Fig. 1).
