ABSTRACT: Background & aims
Under the Chicago Classification of esophageal motility disorders, esophagogastric junction outflow obstruction (EGJOO) includes a varied clinical spectrum that results in diagnostic and management difficulties. We aimed to demonstrate that including upright swallows during high-resolution manometry (HRM) helps identify patients with clinically significant EGJOO.Methods
We performed a retrospective study of consecutive patients diagnosed with EGJOO on HRM from January 2015 through July 2017. HRM studies included 10 supine and 5 upright 5-ml liquid swallows. HRM values, esophagrams, and patient-reported outcomes were evaluated to identify factors associated with objective EGJOO (defined by esophagram) and symptomatic dysphagia (brief esophageal dysphagia questionnaire scores, >10).Results
Of the 1911 patients who had HRM during the study period, 16.2% (310) were diagnosed with EGJOO; 155 patients completed an esophagram and 227 completed the brief esophageal dysphagia questionnaire. Of these patients, 30.3% (47/155) had radiographic evidence of EGJOO and 52.4% (119/227) had symptomatic dysphagia. The median upright integrated relaxation pressure for patients with radiographic evidence of EGJOO or symptomatic dysphagia was higher than for patients without. An upright integrated relaxation pressure >12 mmHg identified patients with radiographic evidence of EGJOO with 97.9% sensitivity and 15.7% specificity; for symptomatic dysphagia these values were 88.2% and 23.1%, respectively.Conclusion
An upright integrated relaxation pressure of >12 mmHg identifies patients with clinically significant esophageal outflow obstruction or dysphagia with a high level of sensitivity. This simple manometric maneuver (upright swallows) should be added to the standard manometric protocol.
