The<unk> , or POEM, is a minimally invasive surgical procedure for the treatment of achalasia wherein the inner circular muscle layer of the lower esophageal sphincter is divided through a submucosal tunnel.

The tunnel is created, and the<unk> <unk> formed, using a flexible endoscope, meaning the entire procedure can be done without external incisions.
