摘要
INTRODUCTION: Gastroesophageal reflux disease (GERD) severity increases with esophageal body hypomotility, but the impact of Chicago Classification (CC) v4.0 criteria on GERD diagnosis is incompletely understood.METHODS: In patients with GERD evaluated with high-resolution manometry and pH-impedance monitoring, CCv3.0 and CCv4.0 diagnoses were compared.RESULTS: In 247 patients, hypomotility diagnosis decreased from 45.3% (CCv3.0) to 30.0% (CCv4.0, P < 0.001). In contrast, within patients with ineffective esophageal motility, proportions with pathological acid exposure increased from 38% (CCv3.0) to 88% (CCv4.0); baseline impedance and esophageal clearance demonstrated similar findings (P < 0.05 for each comparison).DISCUSSION: CCv4.0 hypomotility criteria are more specific in supporting GERD evidence compared with CCv3.0.
