Abstract

Objectives: The study aimed to describe the prevalence of esophageal motility disorders according to the Chicago classification v4.0 (CCv4.0) and compare clinical symptoms, endoscopic findings within groups in patients with gastroesophageal reflux symptoms. Methods: A descriptive study was conducted among 300 patients with gastroesophageal reflux symptoms performed high-resolution manometry (HRM) from May 2022 to August 2022 at the Institute of Gastroenterology and Hepatology. Results: The mean of age was  48.6 ± 13.2 and 61% were females. According to the Chicago classification version 3.0 (CCv3.0), the proportions of esophageal motility groups were: 36% normal, 3.7% absent contractility (AC), 57.3% ineffective esophageal motility (IEM), and 3% distal esophageal spasm (DES). According to CCv4.0, IEM was still the most common motility disorder (39.3%). 31.4% of patients with IEM diagnosed by CCv3.0 were converted to normal motility in CCv4.0. The mean of GerdQ score was significantly higher in absent contractility and IEM groups. The proportion of erosive esophagitis in normal motility group was higher than the IEM group (59.3% versus 45.8%, p=0,03). Conclusions: IEM was the most common motility disorder according to the CCv4.0. The clinical symptoms in absent contractility and IEM were more severe compared to normal esophageal motility.
