Abstract

Background: Available prospectively acquired data on the distribution of oesophageal motor abnormalities in patients being evaluated for non-cardiac chest pain and/or dysphagia are relatively scarce. Aim: To evaluate the distribution of oesophageal motor abnormalities in patients with dysphagia, non-cardiac chest pain or both using the national Clinical Outcomes Research Initiative (CORI) database. Methods: The CORI oesophageal motility database originates from 19 community, university and VA medical centres. Data were collected using a computerized motility report-generating program, combined with the CORI module. Data from each site were encrypted and sent to the CORI National Repository for analysis. The database includes the assessment of the lower and upper oesophageal sphincter function and the motor activity of the oesophageal body. Results: Five hundred and eighty-seven consecutive patients who underwent motility studies between 1998 and 2001 were included in the CORI database and analysed for this report. Four hundred and three patients (69%) had dysphagia as their primary indicator for the examination, 140 patients (24%) had non-cardiac chest pain and 44 patients (7%) had both dysphagia and non-cardiac chest pain. In all three groups, a normal motility study was the most frequent finding (dysphagia, 53%; chest pain, 70%; both, 55%). The most common motility abnormality in the group with non-cardiac chest pain was a hypotensive lower oesophageal sphincter (61%). Nutcracker oesophagus and non-specific oesophageal motility disorders were each diagnosed in only 10% of patients with non-cardiac chest pain. In patients with dysphagia, ineffective peristalsis was the most common oesophageal dysmotility (27%), followed by achalasia and non-specific oesophageal motility disorders (18% and 14%, respectively). Achalasia and non-specific oesophageal motility disorders were the most common oesophageal motility abnormalities in patients with both chest pain and dysphagia (35% and 25%, respectively). Conclusions: The most common oesophageal motility abnormality in patients with non-cardiac chest pain is a hypotensive lower oesophageal sphincter; nutcracker oesophagus and non-specific oesophageal motility disorders are relatively uncommon; the most common oesophageal motility abnormality in patients with dysphagia is ineffective peristalsis and, for those with both dysphagia and non-cardiac chest pain, it is achalasia.
