This video shows a peroral esophageal myotomy (POEM) procedure with intraoperative assessment of esophagogastric junction (EGJ) distensibility using an endoscopic functional lumen imaging probe (EndoFLIP). In order to investigate the physiologic effect of variable myotomy lengths, we perform the myotomy proximal to the EGJ in 2cm increments and record an EndoFLIP measurement after each segment. The proximal 4cm of the myotomy is shown to have no effect on EGJ distensibility, whereas the distal 5cm of myotomy results in a greater than 3-fold increase in distensibility.
