Esophageal impedance planimetry during per-oral endoscopic myotomy guides myotomy extent.

ABSTRACT:

Introduction

Peroral endoscopic myotomy (POEM) is the standard treatment for achalasia. Functional luminal imaging probe (FLIP) technology enables objective measurement of lower esophageal sphincter (LES) geometry, with literature linking specific values to improved post-POEM outcomes. Our study assesses FLIP's intraoperative use in evaluating myotomy extent in real-time.

Methods

Retrospective data from all patients undergoing POEM with intraoperative FLIP measurements were extracted from June 2020 to January 2023. The primary endpoint was intraoperative FLIP measurements, management changes, and symptom improvement (Eckardt score).

Results

Fourteen patients (age 56 ± 14 years, BMI 28 ± 7 kg/m²) were identified. Most patients were female (64%). Predominantl
