According to the current published data and treatment mechanism, ARMS may led to more stenosis while ARMA may be less effective in long term follow-up. The changes of patient's life quality , UGI tract microbiota before and after different endoscopic treatment are also limited. So we want to conduct a exploratory prospective randomized controlled study in evaluating the mucosal healing, demand of PPI, life quality, emotion status, sleep quality, esophageal motility/ acid exposure and saliva microbiota between chronic GERD patients receiving ARMS and ARMA treatment.
In this study, we will enroll 150 patients with chronic GERD. Estimated 40% of patients will be excluded from the inclusion and exclusion criteria. Of 90 patients eligible for the study, estimating 20% may drop out before receiving ARMS or ARMA. Estimated 72 patients will be randomized to receive ARMS or ARMA for GERD treatment. After ARMA, all patients will receive 4 weeks of PPI treatment. Endoscopy and questionnaire follow-up will be performed on week 2, 2 months, 6 months and 12 months after treatment while HRM and 24 hours pH impedance study will be performed 6 months after treatment.
The study will be carried out in 4 years. In the 1st to 3rd year of study, estimating 60,60,30 patients will be evaluated and entered the study in the 1st, 2nd and fisr half of 3rd year. Then all the patients will be followed until the first half of 4th year. At the second half of the 4th year, the saliva sample will be processed, data will be analyzed, and the result will be written.

|---|---|---|---|---|
| Anti-Reflux Mucosectomy | Procedure | ARMS will be performed using gastroscope . The preparation and endoscopy procedure will be done as in regular practice with conscious sedation. The upper gastrointestinal tract will be evaluated in detail first. Then Endoscopic mucosal resection(EMR) will performed at E-C junction, gastric cardia side. About 50%-70% of the EGJ circumference will be resected to create artificial ulcer which will lead to mucosal contraction during the healing process. |
| Measure | Description | Time Frame |
|---|---|---|
| Reflux synptom improvement after different treatment. | Reflux synptom improvement in 6 months after ARMS and ARMA. Complete remission group will be defined as GERD-Q score of <8 and discontinuing PPI medication. Patients with post- ARMS GERD-Q score of <8 and reduced PPI medication will be allocated to the partial response group. Others will be defined as non-response group. | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Comparisons of GERD DeMeester scores | DeMeester scores using 24 hours PH monitor for comparison of ARMS and ARMA groups. | 12 months |
| Comparisons of GERD acid exposure time | Acid exposure time using 24 hours PH monitor for comparison of ARMS and ARMA groups. |

| Anti-reflux mucosal ablation | Procedure | ARMA will be performed using gastroscope . The preparation and endoscopy procedure will be done as in regular practice with conscious sedation. Mucosal ablation will be performed in retroflex fashion following. Then APC with soft coagulation(effect 2, 40W) will be used to mark the area that not going to be ablated at gastric carida over the great curvature direction, about 1.5 scope width. Then submucosa injection with saline and indigo carmine dye will be performed using a 25 guage needle. |
