Title: The Rates of Complete Symptom Relief,Prevetion of Symptom Relapse and Maintenance of Esophagitis Healing for 4-week Versus 8-week Esomeprazole Therapy Among Los Angeles Grades A and B Erosive Esophagitis
Brief Summary: To investigate the impact of initial treatment duration (4-week versus 8-week)of Esomeprazole (40mg) on the rate of symptom relapse and sustained healing of esophagitis in patients with symptomatic erosive esophagitis


Options:
A: Inclusion Criteria:

* patients between the ages of 15 and 80 years
* with clinical symptoms of acid regurgitation, heart burn, or feeling of acidity in the stomach,

2. pregnancy,
3. coexistence of serious concomitant illness (for example, decompensated liver cirrhosis and uremia),
4. previous gastric surgery,

6. symptom score of a validated questionnaire (Chinese GERDQ) less than 12, and
7. equivocal endoscopic diagnosis of Los Angeles Grade A and B erosive esophagitis.
B: Inclusion Criteria:

* Symptoms suggestive of GERD, with heartburn as their predominant symptom (described as a burning feeling, rising from the stomach or lower part of the chest up towards the neck), for longer than 6 months.
* Heartburn occurring for 4 days or more during the last 7 days prior to endoscopy. Or, if PPI treatment has been started within the last 7 days prior to endoscopy, then heartburn occurring for 4 days or more during the last 7 days prior to start of PPI treatment

For South-Africa and Spain:

Women of child-bearing potential may only be included when their pregnancy status is assessed by the investigator prior to endoscopy)
