title: Oesophageal sensitivity to acid in patients with non-cardiac chest pain: is the oesophagus hypersensitive?
abstract: During the past decade, gastro-oesophageal reflux disease has been shown to be the most common identifiable cause of non-cardiac chest pain of oesophageal origin. The development of combined pH-pressures recording systems has also contributed to a better understanding of the underlying mechanisms of pain perception. Beside typical gastro-oesophageal reflux disease, many patients with non-cardiac chest pain appear to have an hypersensitivity to acid or mechanical stimuli, or both. Despite new insights into the pathophysiology of gastro-oesophageal reflux disease, therapy is limited to the suppression of noxious stimuli by antisecretory drugs or surgery. New therapeutic approaches using drugs affecting visceral perception, and well-controlled placebo trials are urgently needed.
