Background:

  • Gastroesophageal reflux disease (GERD) affects millions worldwide.
  • Multichannel intraluminal impedance-pH (MII-pH) monitoring is the gold standard for GERD diagnosis.
  • Reliable extraction of reflux events from MII data remains a significant challenge.

Purpose of the Study:

  • To address the challenge of reflux event detection in MII data.
  • To establish a gold standard dataset for MII data analysis.
  • To facilitate advancements in GERD diagnosis through improved MII data interpretation.

Main Methods:

  • Assembled a dataset of 201 MII episodes.
  • Developed precise reflux episode definition criteria.
  • Utilized a competition framework to assess signal-analyzing methodologies.

Main Results:

  • A curated dataset with gold standard labels was created.
  • The first Isfahan Artificial Intelligence Competition included MII data evaluations.
  • Various signal-analyzing methods were formally assessed.

Conclusions:

  • Accurate reflux event characterization is crucial for GERD diagnosis.
