Summary

Gastric cancer is the fifth most common malignancy and the fourth leading cause of cancer-related deaths. Surgical resection is the primary treatment, with laparoscopic-assisted gastrectomy (LG) being a minimally invasive option. However, LG is limited by restricted instrument mobility and hand tremors, which affect precision. The Da Vinci robotic system enhances surgical precision with 3D magnification, improved hand-eye coordination, tremor filtration, and flexible instruments. It is especially beneficial in complex procedures like D2 lymph node dissection and lower mediastinal lymph node clearance. Unlike laparoscopic surgery, robotic surgery offers superior flexibility and reduced pancreatic injury during dissection. Robotic-assisted gastrectomy (RG) offers advantages over LG, such as reduced blood loss, shorter hospital stays, and improved lymph node dissection. However, its short-term benefits remain debated, and most studies focus on early gastric cancer. The safety and efficacy of RG for advanced gastric cancer are not well-established.

Vascular coagulation is crucial in minimally invasive surgery. Ultrasonic devices, though widely used, can cause thermal damage due to high temperatures. In contrast, the Vessel Sealer Extend (VSE) offers greater flexibility and precision. It allows 540° instrument rotation, coagulates vessels up to 7 mm in diameter with lower energy, and minimizes thermal injury. Retrospective studies show RG with VSE may have faster recovery and fewer complications than LG. However, further prospective, multicenter studies are needed to confirm these benefits for advanced gastric cancer.

The investigators propose a multicenter, observational study to evaluate RG with VSE in advanced gastric cancer, assessing safety, recovery, and oncological outcomes.
