Artificial intelligence technology is used to realize high-quality 3D scene reconstruction, whole process segmentation, scene activity understanding for common surgery guidance in hepatobiliary surgery, as well as intelligent identification, perception, early warning of key events in the whole process of endoscopic surgery (such as bleeding, blocking, tumor location, anastomosis, etc.), and decision-making assistance

The purpose of this clinical trial is to find out the effectiveness of voronasan in combination with aluminum phosphate gel in the treatment of post-operative ESD ulcers. It will also find out about the safety of vunorasan in combination with aluminum phosphate gel. The main questions it aims to answer are:
1. Do vonorasan in combination with aluminum phosphate gel clinically effective in the treatment of post-operative ESD ulcers?
2. What medical problems do participants have when taking drug vonorasan in combination with aluminum phosphate gel? Researchers compared the drug voransen in combination with aluminum phosphate gel to esomeprazole in combination with aluminum phosphate gel to see if voransen in combination with aluminum phosphate gel worked better for post-operative ESD ulcers.
Participants will:
Intravenous lansoprazole 1-3 days after ESD and oral voronasan combined with aluminum phosphate gel or esomeprazole combined with aluminum phosphate gel 3-56 days after ESD.
Record their symptoms, endoscopic ulcer grading, ulcer size and Calculate ulcer healing rate at weeks 2 and 8.
