Comparison of oesophageal function in patients with acid and non-acid reflux

Background: Decreased oesophageal motility has been described in patients with GastroOesophageal Reflux Disease (GORD); however it is not clear if this impairment is consequence or cause of increased acid exposure. It is known that non-acid reflux causes symptoms. Non-acid reflux may contain pancreatic enzymes and bile that can also be injurious to the oesophageal motility. Therefore the aim of the present study was to investigate the oesophageal motility of patients with symptomatic reflux that is attributed predominately to non-acid reflux and to compare them with patients with symptomatic acid reflux.
