The purpose of the present study was to investigate the relationship of the gastroesophageal pressure gradient (GEPG) to lower esophageal sphincter pressure (LESP) in normal and in severely obese subjects. Eight lean volunteers with no clinical evidence of gastroesophageal reflux and eight asymptomatic severely obese patients (at least 80% over their ideal weight) underwent esophageal manometric studies with measurements of the LESP and GEPG in both inspiration and expiration. The LESP/GEPG… CONTINUE READING
