This video is an illustration of functional lumen imaging probe measurements of esophagogastric junction distensibility in laparoscopic Heller myotomy and peroral endoscopic myotomy (POEM) for achalasia.

It specifically shows changes in distensibility with each operative step, emphasizing the effect of distal incremental gastric myotomy on EGJ function intraoperatively. It also provides a review of important operative steps of both Heller and POEM.
