Early Gastric Cancer, Endoscopic Submucosal Dissection
Conditions
Brief summary
This study is a single-center, prospective, group-controlled clinical trial, aiming to clarify the relationship between the depth of dissection and scar formation in the treatment of early gastric cancer by ESD, and to provide high-quality evidence-based medicine for the treatment of early gastric cancer.
Detailed description
This project intends to compare the scar size of ESD for early gastric cancer with different peeling depths, explore the relationship between ESD peeling depth, scar formation and gastric function, and clarify the differential impact of different peeling depths on the prognosis of patients. We plan to provide evidence for guidelines of early gastric cancer ESD treatment based on the related data. In further, the project show insight into a more effective clinical technique which profit patients better prognosis.
