Complications of Endoscopic Pressure Study Integrated System: Review of 1205 Cases in 10 Years' Experience.

ABSTRACT:

Background and aims

The Endoscopic Pressure Study Integrated System (EPSIS) is a novel endoscopic tool to assess lower esophageal sphincter (LES) function by monitoring intragastric pressure (IGP) through insufflation. While previous studies have confirmed its diagnostic utility for LES dysfunction-related disorders such as gastroesophageal reflux disease and achalasia, there have been no reports evaluating its safety. Thus, this study aimed to assess its complication rates and detailed characteristics.

Methods

We retrospectively reviewed 1205 consecutive EPSIS cases performed between December 2015 and September 2024 at our institution. Cases with adverse events (AEs) were identified, and clinical characteristics, waveform patterns, IGP parameters, and need for additional tr
