Changes in pressure, length, and position of the gastro-oesophageal junction high pressure zone caused by Müller manoeuvre

  • Changes in the hiatus hernia patients were measured both within the proximal high pressure zone (HPZ 1) and the hiatal canal (HPZ 2).

  • All values are mean (SEM).

  • 5-150 p<0.05 versus normal; p<0.05 versus movement of HPZ 2.
