Rapid drink challenge test during esophageal high resolution manometry in patients with esophago‐gastric junction outflow obstruction

Esophago-gastric junction (EGJ) outflow obstruction is of unclear significance. Rapid drink challenge (RDC) test is easy to perform during esophageal high resolution manometry. We aimed to assess the yield of RDC test in patients with EGJ outflow obstruction.Manometry studies of patients with EGJ outflow obstruction according to the Chicago Classification v3.0 were retrospectively reviewed. Pan-esophageal pressurization (PEP), esophageal...
