Background: Intramural surgery techniques, particularly esophageal peroral endoscopic myotomy (E-POEM), gastric peroral endoscopic myotomy (G-POEM), and peroral endoscopic myotomy for Zenker's (Z-POEM), have emerged as forefront minimally invasive endoscopic procedures. While several studies have reported on the outcomes in North America and Asia, evidence in the Middle East and North Africa remains limited. This study aims to evaluate the feasibility and safety of intramural surgery techniques within this region. Methods: This retrospective cohort study was conducted with approval from the institutional review board. All patients who underwent esophageal peroral endoscopic myotomy, gastric peroral endoscopic myotomy, and peroral endoscopic myotomy for Zenker's from January 2016 to August 2023 were included. Results: In total, 119 patients underwent intramural surgery procedures during this period. The esophageal peroral endoscopic myotomy group had 81 (68%) patients, the gastric peroral endoscopic myotomy had 34 (28.6%) patients, and the peroral endoscopic myotomy for Zenker's had 4 (3.4%) patients. The full cohort was 48.7% female, with a mean overall age of 40.5 years. The mean overall body mass index was 27.5 kg/m 2 . The chief complaint was dysphagia ( n = 80, 67.2%). All cases were successfully completed endoscopically. During the first 30 days, the most common complications were nausea/vomiting requiring admission ( n = 4, 4.76%) and pneumomediastinum ( n = 2, 2.38%). At a follow-up of 19 months, there were four mortalities; the causes of death were cardiac arrest (three cases) and end-stage prostate cancer (one case). Conclusions: Intramural surgery techniques are safe and technically feasible with low complication rates. Our study suggests that clinical success in the Middle East and Northern Africa population is comparable to larger international series.
