Endoscopic techniques for myotomy of the lower esophageal sphincter and pylorus. PURPOSE OF REVIEW: Peroral endoscopic myotomy (POEM) and gastric peroral endoscopic myotomy (G-POEM) are minimally invasive endoscopic procedures for the treatment of esophageal motility disorders and refractory gastroparesis, respectively. In this review, we highlight the most recent publications on the technical aspects of POEM and G-POEM. RECENT FINDINGS: POEM has evolved into a standard therapeutic option in patients with all achalasia subtypes with excellent durability and safety profile. G-POEM is a novel endoscopic procedure with promising results in terms of efficacy, safety, and symptom improvement in patients with refractory gastroparesis. SUMMARY: POEM and G-POEM are novel endoscopic procedures. Practice patterns vary among endoscopists and procedure techniques continue to evolve. Comparative studies examining outcomes of different techniques are needed.
