Background & Aims: The aim of this study is to present the experience of our center over the last 8 years in a series of patients with Zenker's diverticulum (ZD), treated using an endoscopic, minimally invasive procedure. Methods: We retrospectively included 31 patients with a previously established diagnosis of ZD based on endoscopic and oral contrast examinations. Patients' age, comorbidities, size of the diverticulum or previous endoscopic treatment were not considered exclusion criteria. A soft, flexible diverticuloscope to expose the septum and a dual knife for "cutting" the diverticular septum were used. We analyzed the short term efficacy based on symptomatic relief and occurrence of side effects, and long term efficiency at 6 and 12 months by clinical assessment, upper gastrointestinal endoscopy and oral contrast media passage. Results: Patients had a mean age of 67 years (range 42-86); 55% of them were male. All patients reported symptom relief after the procedure. A decrease of more than 70% from the initial size of the diverticulum was noted. There were 3 cases (9.67%) of intraprocedural hemorrhage, endoscopically managed. No serious post-procedural complications and no mortality were reported. The mean procedural time was 21.87 minutes (range 15-25 minutes). Average hospitalization was 2.5 days. Five patients developed recurrence and needed a second session of endoscopic treatment for achieving complete myotomy. Conclusions: Endoscopic management for ZD was efficient and safe in our series of patients. A short hospitalization period was required. [ABSTRACT FROM AUTHOR]
