This video demonstrates the use of a functional lumen imaging probe (FLIP) to evaluate esophagogastric junction (EGJ) distensibility in real-time during operations for achalasia. FLIP is additionally used to test the physiologic effect of variable myotomy length proximal to the EGJ. This strategy is shown during two cases: a peroral esophageal myotomy (POEM) and a laparoscopic Heller myotomy.
