The diaphragm as an anti-reflux barrier: A manometric, oesophagoscopic, and transmucosal potential study

AUTOR(ES)
RESUMO

An infusion technique was used to measure pressures at the lower end of the oesophagus in normal patients and in those with hiatus hernia. These studies show a band of raised pressure at the lower end of the oesophagus in normal patients. This band was abnormally long in the majority of patients with hiatus hernia, but in others it resolved into two bands, particularly in patients with hiatus hernia and a short oesophagus.
