measurement of resting pressure of the lower oesophageal sphincter ( les ) failed to identify individual patients with reflux oesophagitis , although the mean pressure in 26 patients with oesophagitis ( 10.1 +/- 5.2 mm hg ) was significantly lower that in 13 patients without oesophagitis ( 16.8 +/- 10.2 mm hg , p less than 0.005 ) .
