Abstract

The past decade has seen new technological advances in the investigation of oesophageal motility disorders. Multichannel intraluminal impedance monitoring has been used as an adjunct to conventional manometry in the assessment of oesophageal function, independent of radiography. High resolution manometry provides additional information over conventional manometry, and its topographic analysis makes interpretation of studies easier. Both utilities in non-obstructive dysphagia have been used ultimately in research; however, more studies are addressing their clinical application.
