About this study
Official title: Intravenous Esomeprazole Combined With Sucralfate Suspension for Ulcer Healing and Complication Prevention After Gastric Endoscopic Submucosal Dissection: A Prospective, Randomized, Controlled Trial
Endoscopic submucosal dissection (ESD) is an established treatment for early gastric cancer and precancerous lesions. Post-ESD artificial ulcers may lead to complications including delayed bleeding (3-15%) and prolonged healing. Current guidelines recommend high-dose proton pump inhibitors (PPIs), but evidence for additional mucosal protective agents remains limited.
This study aims to evaluate whether combining sucralfate suspension with standard intravenous esomeprazole therapy improves ulcer healing and reduces complications after gastric ESD compared to esomeprazole alone.

This is a prospective, randomized, controlled, outcome-assessor-blinded trial. A total of 120 patients undergoing gastric ESD will be randomly assigned 1:1 to receive either:
- Intervention group: Intravenous esomeprazole 40mg twice daily (3 days) followed by oral esomeprazole 40mg once daily PLUS sucralfate suspension 1g twice daily for 8 weeks
- Control group: Intravenous esomeprazole 40mg twice daily (3 days) followed by oral esomeprazole 40mg once daily for 8 weeks The primary outcome is ulcer reduction rate at 4 weeks post-ESD, assessed by endoscopy. Secondary outcomes include complete ulcer healing rate at 8 weeks, delayed bleeding rate, symptom scores, and safety parameters.
This study will provide high-quality evidence regarding the role of sucralfate as an adjunctive therapy for post-ESD ulcer management and may inform future clinical guidelines.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Endoscopic submucosal dissection (ESD) is an established treatment for early gastric cancer and precancerous lesions. Post-ESD artificial ulcers may lead to complications including delayed bleeding (3-15%) and prolonged healing. Current guidelines recommend high-dose proton pump inhibitors (PPIs), but evidence for additional mucosal protective agents remains limited.
This study aims to evaluate whether combining sucralfate suspension with standard intravenous esomeprazole therapy improves ulcer healing and reduces complications after gastric ESD compared to esomeprazole alone.
This is a prospective, randomized, controlled, outcome-assessor-blinded trial. A total of 120 patients undergoing gastric ESD will be randomly assigned 1:1 to receive either:
- Intervention group: Intravenous esomeprazole 40mg twice daily (3 days) followed by oral esomeprazole 40mg once daily PLUS sucralfate suspension 1g twice daily for 8 weeks

A Phase 4 study testing Esomeprazole (Intravenous), Esomeprazole (Oral) and Sucralfate Suspension in people with Early Gastric Cancer and Gastric Dysplasia, run by LanZhou University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 23 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Qiangqiang Tian (86+15009460497, tianqq2023@lzu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ulcer Reduction Rate at 4 Weeks Post-ESD (time frame: 4 weeks after ESD procedure (±3 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07312370, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
