Abstract
Cricopharyngeal bars (CPBs) are a unique etiology of oropharyngeal dysphagia resulting from fibrous replacement of the cricopharyngeal muscle (CPM) due to acid reflux or mechanical injury. Dysphagia due to CPBs mimics manifestations of Zenker’s diverticula (ZD). While no medical therapy is required in asymptomatic patients, symptomatic patients are managed with endoscopic dilation or open surgical myotomy of the CPM. Cricopharyngeal peroral endoscopic myotomy (CP-POEM) is an emerging technique utilized in the management of dysphagia due to CPBs. No prior studies have assessed the outcomes of CP-POEM.
