At Jimenez Diaz Foundation University Hospital, Peroral Endoscopic Myotomy (POEM) is performed using specialized therapeutic endoscopy techniques and comprehensive esophageal assessment. Established in 1935, this ISO, JCI accredited hospital in Madrid, Spain has 686 beds and offers advanced gastroenterology, endoscopy, and minimally invasive treatment services.

Peroral Endoscopic Myotomy may be considered for appropriately selected patients with achalasia and certain other esophageal motility disorders. Before treatment, investigations such as upper gastrointestinal endoscopy, high-resolution esophageal manometry, and contrast imaging may be performed to confirm the diagnosis and characterize the disorder. During POEM, the endoscopist creates a submucosal tunnel and cuts the targeted esophageal and lower esophageal sphincter muscles to reduce resistance to swallowing.
