The 16\u2009cm FLIP catheter allows for topographical assessment of the esophageal body, and previous intraoperative studies have only utilized the 8\u2009cm catheter or combined data from both catheters.

A tailored short myotomy (\u2264\u20094\u2009cm) using FLIP was performed in 10% of cases with comparable outcomes in LES obstruction and GERD metrics compared to &gt;\u20094\u2009cm myotomy length. On the basis of topographical FLIP findings, the myotomy was extended to capture spastic body features in 32% of cases including Type 2 achalasia (5), epiphrenic diverticulum (3) and prior myotomy (10). In intervention\u2010naive patients, 70.5% achieved clinical success (Eckardt \u2264\u20093) at median follow\u2010up of 30.9 months (IQR 6.5\u201340.9 months) with improvement in LES obstruction and GERD metrics among the intermediate follow\u2010up cohort.
