Identifying hiatal hernia with impedance planimetry during esophageal distension testing.

ABSTRACT:

Introduction

Functional luminal imaging probe (FLIP) Panometry evaluates the esophageal response to distension involving biomechanics and motility. We have observed that hiatus hernia (HH) is evident during FLIP studies as a separation between the crural diaphragm (CD) and lower esophageal sphincter (LES) like what is seen with high-resolution manometry (HRM). The aim of this study was to compare FLIP findings to endoscopy and HRM in the detection of HH.

Methods

A total of 100 consecutive patients that completed FLIP during sedated endoscopy and HRM were included. LES-CD separation was assessed on FLIP and HRM with the presence of HH defined as LES-CD ≥1 cm. The agreement was evaluated using the kappa (κ) statistic.

Results

Hiatal hernia was detected in 32% of patient
