Dynamic Key Vascular Anatomy Dataset for D2 Lymph Node Dissection During Laparoscopic Gastric Cancer Surgery

The Laparoscopic Gastric Cancer Surgery Key Vascular Anatomy Dataset (LapGC-KVAD-30) was extracted from thirty complete surgical videos and contains annotations for fifteen types of key vessels across eight D2 lymph node dissection (LND) scenes. The LapGC-KVAD-30 uniquely contains 5303 frames that showcase the dynamic process of key vessels from initial appearance to full exposure (or ligation), providing essential information for effective and safe LND. (This dataset is also called Southern Medical University- Nanfang Hospital - Gastric Cancer - 01 Dataset, SMU-NF-GC-01)
