Lymph Node Metastasis and Tumor Deposit in the Short Gastric Mesentery Following Total Gastrectomy With D2 Lymphadenectomy Plus Complete Mesogastric Excision for Gastric Cancer: A Prospective Observational Study
This study aims to explore lymph node metastasis in the short gastric mesentery following total gastrectomy with D2 lymphadenectomy plus complete mesogastric excision, providing evidence-based medicine for standardizing lymph node dissection in gastric cancer.
