Tumors originating from the muscularis propria layer of esophagus are usually removed by thoracoscopic resection. With the introduction of new endoscopic therapeutic techniques, some of these tumors could be treated by endoscopic submucosal dissection (ESD). However, the above endoscopic methods are associated with a high risk of perforation and it is hard to close the perforation through the endoscopy. Recently we successfully resected a tumor originating from the muscularis propria layer of the esophagus by submucosal tunneling endoscopic resection (STER), which was based on peroral endoscopic myotomy (POEM) and ESD. Compared with ESD, STER is a safe, economic and less invasive treatment. Even when perforation happens, it is easier to close the tunnel with the endoscopic clips which can help stopping the leak of air and digestive fluids. In this case, we found STER wss an effective and safe endoscopic procedure to remove tumors originating from the muscularis propria layer in the esophagus.
