Peroral Endoscopic Myotomy (POEM) is a treatment for patients experiencing swallowing disorders such as achalasia, which is when the ring of muscle between the esophagus and stomach is too tight and does not allow for food to be swallowed into the stomach.
POEM is an endoscopic procedure where a flexible tube with a camera is inserted into the mouth to the esophagus and a small cut is made at the lower end of the esophagus. This procedure is less-invasive than surgery leading to quicker recovery time and fewer complications.
