Abstract:
Objective To investigate the pathogenesis of gastroesophageal reflux (GERD) diseaserelated risk factors.Methods A questionnaire survey of 1213 patients in our hospital gastroenterology clinic visits was conducted,including irregular feeding time,eating too full,eating before going to bed,like greasy food,spicy food and alcohol consumption,and smoking.The results of the investigation were rated;95 patients were selected as the observation group,another 30 healthy volunteers were selected as the control group.Esophageal and gastric pressures were measured on the observation group and control subjects,respectively.Results Multivariate logistic regression analysis showed that often eating to satiety (OR =11.5322,P =0.0135),before going to bed eating (OR =14.6537,P =0.0005),like greasy food (OR =11.6547,P =0.0089),spicy food (OR =12.5674,P =0.0031),heavy drinking (OR =10.9874,P =0.0003),and smoking (OR =10.3846,P =0.0013) were important factors affecting the incidence of GERD; length of lower esophageal sphincter (LESL) mean of the observation group was (3.27 ±0.29)cm,intragastric pressure (GP) mean (1.63 ± 1.12) kPa,lower esophageal sphincter pressure/intragastric pressure (LESP/GP) =0.55 ±0.41,LESP-GP mean (-0.33 ±0.34) kPa,with the control group [(3.90 ± 0.42) cm,(1.12 ± 0.94) kPa,1.72 ± 0.82,(0.88 ± 0.41) kPa] were statistically significant (t' =8.99,P ＜0.05,t =2.43,P ＜0.05,t' =8.18,P ＜0.05,t =7.91,P ＜0.01).Conclusions Eating too full,eating before going to bed,like greasy food,spicy food,heavy drinking,smoking,and other bad diet and lifestyle were important risk factors of GERD.The lower esophageal sphincter dysfunction and esophageal clearance capacity play important role in the pathogenesis of gastroesophageal reflux disease.
