A prospective randomized comparison of HD and 4K laparoscopic surgery for gastric cancer will be performed, to evaluate the clinical value and provide theoretical basis and clinical experience for the extensive application of the 4K laparoscopic technique. The evaluation parameters are perioperative clinical efficacy, postoperative life quality, immune function and 3-year survival and recurrence rates.
The purpose of this study is to explore the feasibility of 4K Laparoscopic Surgery for Gastric Cancer.
