A STUDY ON ESOPHAGEAL KINETICS OF REFLUX ESOPHAGITIS WITH OR WITHOUT SLIDING HIATUS HERNIA / 解放军医学杂志

To investigate the character of esophageal manometry in reflux esophagitis(RE) with or without sliding hiatus hernia(SHH). Ambulatory 24 hours esophageal pH metry and esophageal manometry were studied in 50 patients with RE, and 50 RE patients with SHH. Lower esophageal sphincter(LES) competence was significantly boorer in SHH groups as compared with RE group, esophageal sphincter length(LESL) was (1 31?0 33)cm in SHH groups and (2 10?0 86)cm in RE group, and lower esophageal sphincter pressure(LESP) was (1 17?0 53) kPa in SHH groups and (2 16?0 65) kPa in RE groups( P
