High-resolution manometry predicts the success of oesophageal bolus transport and identifies clinically important abnormalities not detected by conventional manometry

Abstract

Background and aims: High-resolution manometry (HRM) is a recent development in oesophageal measurement; its value in the clinical setting remains a matter of controversy. (i) We compared the accuracy with which bolus transport could be predicted from conventional manometry and HRM. (ii) The clinical value of HRM was assessed in a series of patients with endoscopy-negative dysphagia in whom conventional investigations had been non-diagnostic. Method: (i) Control subjects and patients with endoscopy-negative dysphagia underwent concurrent HRM and video-fluoroscopy. Ninety-five records were reviewed using HRM with spatiotemporal plot and conventional line plots of the pressure data derived fro..
