When early gastrointestinal neoplasia is diagnosed, patients often face a critical clinical decision: undergo partial or total organ resection, or pursue organ-preserving endoscopic en bloc dissection.
| Clinical Dimension | Endoscopic Submucosal Dissection (ESD) | Traditional Open / Laparoscopic Gastrectomy |
|---|---|---|
| Invasive Approach | Natural luminal access via mouth/anal canal; 0 external scars | Abdominal wall incisions (laparoscopic trocars or 15–20cm open laparotomy) |
| Organ Preservation | 100% preservation of stomach / colon volume & anatomy | 50% to 100% loss of stomach volume (subtotal or total gastrectomy) |
| Inpatient Stay | Typically ~3 to 5 days observation* | Typically 10 to 14 days hospitalization* |
| Recovery & Diet | Liquids in 24-48h; normal dietary habits resumed within weeks | High risk of Dumping Syndrome, anemia, postprandial nausea, lifelong B12 injections |
| Curative Oncology Criteria | R0 en bloc resection equal to surgery for indicated early lesions | Standard for advanced disease with deep muscularis or nodal spread |

The stomach is not merely a holding pouch; it secretes gastric acid, intrinsic factor (essential for Vitamin B12 absorption), and regulates metabolic peptide hormones like ghrelin. Post-gastrectomy syndrome severely impairs nutritional status and psychological well-being.
Under Prof. Xu Shuchang's protocol, patients diagnosed at the mucosal or superficial submucosal stage (< 500μm depth, SM1) are strongly prioritized for ESD, allowing curative removal of neoplastic cells while keeping the stomach completely intact.
