Triangle Tip-Jet Knife used as "probe mode" during C-POEM for the treatment of cricopharyngeal achalasia.

Cricopharyngeal achalasia is a rare esophageal motility disorder characterized by the inability to relax of the cricopharyngeal muscle during swallowing. Peroral endoscopic myotomy (POEM) is a minimally invasive endoscopic technique for treating achalasia that has gained increasing popularity in recent years. In this context, cricopharyngeal peroral endoscopic myotomy (C-POEM) has emerged as a novel technique for the management of cricopharyngeal achalasia.
