Abstract:
Background:Besides typical gastroesophageal reflux symptoms,some reflux esophagitis( RE)patients also complain“morning sour taste in mouth”,but related studies are rare. Aims:To study the pathophysiology of RE with sour taste in mouth. Methods:Fifty-two RE patients with typical regurgitation symptom and confirmed by endoscopy from Mar. 2013 to Oct. 2013 at Tianjin Medical University General Hospital were enrolled. Patients were divided into two groups according to whether there was an existence of morning sour taste in mouth. Results of esophageal manometry and 24-hour esophageal impedance-pH monitoring were analyzed. Nine healthy volunteers who had esophageal manometry performed were served as controls. Results:Length of lower esophageal sphincter( LESL)was shortened and LES pressure( LESP)and effective peristalsis of esophageal body were decreased in both RE groups when compared with controls( P ﹤ 0. 05 ). Upper esophageal sphincter pressure( UESP)was significantly lower and more nocturnal reflux episodes occurred in RE group with sour taste than those without( P ﹤ 0. 05 );however,no significant differences in other manometric and reflux parameters were found between RE groups with and without sour taste(P﹥0. 05). Conclusions:Esophageal motility and reflux events in RE patients with morning sour taste in mouth are somewhat different from those without sour taste. Decrease in UESP might be an important pathophysiological mechanism of sour taste in mouth in RE patients.
