THE PREVALENCE OF ESOPHAGEAL MOTILITY DISORDERS BASED ON CHICAGO 4.0 CLASSIFICATION IN PATIENTS WITH UPPER GASTROINTESTINAL SYMPTOMS
Main Article Content
Abstract
Objective: Describe the distribution of motility disorders (MDs) according to the Chicago 4.0 classification on high resolution manometry (HRM) in patients with upper gastrointestinal (UGI) symptoms. Subjects and methods: Our study used retrospective data on patients who had UGI symptoms and underwent HRM at Hoang Long Clinic - Institute of Gastroenterology and Hepatology between September 2020 and February 2023. MDs are diagnosed based on the Chicago 4.0 criteria. Results: 2219 patients met the criteria, 4.1% had a diagnosis of GERD based on endoscopy results and 24-hour esophageal impedance pH measurement. Among patients presented with UGI symptoms, 42.2% had MDs, of which IEM was the most common (36.1%), achalasia had a low prevalence (2.3%). The prevalence of IEM tended to be higher in the GERD group than in the group with upper gastrointestinal symptoms (46.2% vs 36.1%). The prevalence of achalasia and esophagogastric junction outflow obstruction were 3.8% and 3.5% in patients with dysphagia and those with typical symptoms of GERD. Conclusion: Motility disorders are common in patients with upper gastrointestinal symptoms, of which IEM is the most common disorder.
