What are the target distensibility index and EGJ diameter values on EndoFLIP following peroral endoscopic myotomy (POEM)?

An increase in the intraoperative EGJ-DI following POEM correlates with improved symptomatic response. Persistent DI < 2 is associated with poorer outcomes. When using EndoFlip, our team evaluates patients following POEM by using the 60 mL fill volume and aims for a DI of at least 2.8 and a diameter...
