Abstract

Background: It has been suggested that multiple rapid swallowing should be added to oesophageal manometry. Aim: To prospectively evaluate whether 10 and 200. mL multiple rapid swallowing provide different information concerning motor function. Methods: 30 consecutive patients with oesophageal symptoms, 13 achalasia patients after successful pneumatic dilation and 19 healthy subjects performed eight 5. mL single swallows, two 10. mL and one 200. mL multiple rapid swallowing. Results: Almost all of the healthy subjects and two-thirds of the patients with oesophageal symptoms showed motor inhibition during both 10 and 200. mL multiple rapid swallowing. The oesophago-gastric pressure gradient was significantly higher during 200. mL multiple rapid swallowing within each group (p
