This article discusses the use of a modified endoscopic procedure called Peroral Endoscopic Septotomy (POES) for the management of a symptomatic Zenker's diverticulum in a 75-year-old male patient with multiple comorbidities. The procedure involved making a mucosal incision on the septum, cutting the thick cricopharyngeal muscle, and performing submucosal dissection on both sides of the septum. The patient's post-procedure esophagogram showed a small residual diverticular pouch with no leak, and after 12 weeks, the patient was asymptomatic. The article includes a video demonstrating the procedure. [Extracted from the article]
