INTRODUCTION: Patients with esophageal symptoms often remain with an uncertain diagnosis after high-resolution manometry.
AIM: To determine the added value of concomitant pressure and symptom analysis in response to a rapid drink challenge (RDC).
METHODS: In consecutive patients referred for esophageal manometry, a RDC consisting in free drinking of 200 ml of water as quick as possible was performed after the standard single water swallows manometry. Both pressure patterns and usual symptoms induced by the RDC were analyzed.
RESULTS: A total of 1319 patients were included, (64.7% women, mean age 58.2 years, range 11-90). There were significant differences in pressure responses between patients with obstructive disorders, major hypercontractile disorders, esophageal hypomotility disorders and normal motility. The RDC provoked usual symptoms in 388 (29.4%) patients, associated with hyperpressive and obstructive patterns in 14.0% and 16.6%, respectively. Reproduction of dysphagia and regurgitation (not pain) was significantly associated with abnormal pressure responses during the RDC (p < 0.001 and p = 0.002, respectively). The RDC elicited both abnormal pressure patterns and symptoms in 6.2%, 1.6%, and 20.8% of patients with normal motility, ineffective esophageal motility, and esophago-gastric junction outflow obstruction, respectively.
CONCLUSION: Concomitant evaluation of symptoms and pressure responses to a RDC may increase the specificity of esophageal motor testing in patients with inconclusive diagnosis or normal esophageal motility.
