The total symptom improvement rate was 92.3% at 6 weeks. After 6- week treatment,the endoscopic healing rate of grade I esophagitis was 93.75% much higher than grade II of 74.1% and grade III and grade IV of 66.7%(P<0.05).The percentage of the total time of reflux and the total number of reflux decreased from(17.47±5.93)% and(151.2±37.5) times to(5.21±0.44)%(P<0.01) and(60.1±14.83) times(P<0.01),respectively.Conclusion:Esomeprazole is effective in the treatment of reflux esophagitis.
