| Abstrakt: | Background: Primary esophageal motility disorders present with a spectrum of symptoms where manometry plays an important role. We designed this study to evaluate the utility of esophageal manometry among various symptoms. Materials and Methods: This is a single-center observational study conducted over 5 years in a tertiary referral center. A total of 564 patients who underwent high-resolution esophageal manometry (HREM) using a 16-channel water perfusion system were included in the study. Their clinical profile and manometric findings, as per the Chicago classification version 4.0, were recorded, and the diagnostic utility of HREM with respect to symptoms was studied. Results: Motility disorders were identified in 48.8% of patients, the most common being Achalasia cardia (32.4%). Dysphagia (55.5%) was the most common indication of manometry, followed by gastroesophageal reflux disease (GERD) (34.9%), chest pain (6.2%), and symptoms such as belching, globus, and hiccoughs (3.4%). Among those who were re-classified from Chicago classification v3.0 to v4.0, 21.2% had a newer diagnosis. Among the patients with dysphagia, HREM revealed the highest yield of detecting an abnormal esophageal motility test (70.6%); meanwhile, this yield was much lower in those with GERD (21.8%), chest pain (22.8%), and other symptoms (15.7%). The most common finding among those with dysphagia was Achalasia cardia (55.9%), while the study was normal among those with GERD (78.1%), chest pain (77.1%), and other symptoms (84.2%). The sensitivity and specificity of dysphagia for major motility disorders were 65% and 91%, respectively, with a positive predictive value of 90%. Conclusion: HREM has high accuracy and a good diagnostic yield among patients with dysphagia, with the most common finding being Achalasia cardia.
