Abstract:
Objective To investigate the relationship between gastroesophageal flap valve (GEFV) and reflux esophagitis(RE).Methods We analyzed 239 cases of RE diagnosed by endoscopy in our hospital from January 2007 to December 2009.RE was classified by Los Angeles classification system and GEFV by Hill system.The association of GEFV with RE was analyzed.Results The overall incidence of abnormal GEFV was32.9% (316/960) and that of RE was 24.9% (239/960).The incidence of severe RE ( grade C and D) in abnormal GEFV group was significantly higher than that in normal GEFV group (23.1% vs.2.4% , P = 0.000).RE grades were positively correlated with GEFV grades (r = 0.308, P = 0.000 ).The incidence of abnormal GEFV in RE patients was higher than that in non-RE (65.3% vs.22.2% ,P = 0.00 ).In terms of gender, there were more males than females in both RE group (63.6% vs.36.4% ) and abnormal GEFV group (60.1% vs.39.9% ).Additionally, incidence of RE increased with age, i.e.positively correlated with age (r=0.214,P =0.000).The incidence of abnormal GEFV also increased significantly in those over 30 years old, i.e.positively correlated ( r = 0.129, P = 0.000).Conclusion There is correlation between GEFV abnormality and RE.GEFV provides useful information for assessment and prediction of the reflux status of the patients.
