Abstract
The usefulness of oesophageal manometry as a clinical tool has been assessed in 202 patients requiring detailed investigation for troublesome oesophageal symptoms, who first presented between June 1979 and May 1982. Only 12 were found to have specific motility disorders such as achalasia and scleroderma. A total of 147 had a variety of non-specific motility disorders and, of these, 112 (76·2 per cent) had coexistent gastro-oesophageal reflux. There was a significant association between the symptoms of dysphagia and the occurrence of predominantly non-propagated motor activity in the oesophagus. A similarly significant relationship existed between crushing chest pain and oesophageal spasm. Despite this statistical association, detection and treatment of gastro-oesophageal reflux was found to be the most useful part of clinical management. Symptoms of associated motility disorders resolved in more than 90 per cent of patients treated by Nissen fundoplication. Pre-operative assessment of motility was of no value in detecting those who might develop postoperative dysphagia. Oesophageal manometry is useful for the assessment of a small proportion of patients with oesophageal symptoms in whom gastro-oesophageal reflux has been excluded by vigorous investigation, including 24 h pH recording.
