Background: Advances in high-resolution esophageal manometry (HREM) have overturned the clinical assessment of esophageal motility disorders. It has been widely incorporated into clinical practice as it is a delicate diagnostic tool for assessing esophageal motility patterns.

Objective: To assess the diagnostic ability of HRM in categorization of esophageal motility disorder using the Chicago Classification v3.0

Patients and Methods: a retrospective descriptive study done on 100 adult patients who underwent esophageal manometry test in the Endoscopy unit of Gastroenterology and Hepatology center at Azadi Teaching Hospital in Duhok city. The study was conducted from January 2021 to March 2022 by reviewing the high-resolution esophageal manometry of these patients using the Chicago classification v3.0. The recorded esophageal symptoms were correlated with the findings obtained during HREM test.

Results: The mean age of the participants was 44.8 years with a standard deviation of 16 year. Females were on average older than males with a mean age of 47.8 years compared to 41.2 year for males. More than half of the patients (53%) had dysphagia as the main symptom that HRM done for. Globus sensation was the second one (14%) followed by Gastroesophageal reflux disease (GERD) (13%). The yield of HRM found to be abnormal (77%) as esophageal motility disorders. Those patients with dysphagia had achalasia II as the highest frequency (28.3%), while no even one patient of those with GERD, globus sensation or nausea and vomiting had achalasia detected by HRM. The most frequent result of GERD patients was esophagogastric junction outflow obstruction (38.5%). More than half (57.1%) of patients with globus sensation had a normal HRM test. Distal esophageal spasm was found to be the most frequent finding among patient with non-cardiac chest pain.

Conclusion: There is an apparent diagnostic value of HRM in categorization of esophageal dysmotility when applying the Chicago Classification v3.0 in those patients with suggestive symptoms of motility disorders.
