Comparison of Vagus Nerve-preserving RADG and Conventional RADG for AGC

June 17, 2016 updated by: Yingxue Hao

Comparison of Vagus Nerve-preserving Robot-assisted Distal Gastrectomy (RADG) and Conventional Robot-assisted Distal Gastrectomy for Advanced Gastric Cancer (AGC)

Through comparative observation of robot vagus nerve preserving distal gastric cancer radical surgery and conventional robot distal gastric cancer radical surgery (not reserved vagus nerve) operative and postoperative indicators, and evaluating the feasibility and safety of vagus nerve preserving distal gastric cancer radical surgery in advanced gastric cancer. Which can provide the evidences for the clinical development of the preserving function gastric cancer surgery.
