About
Dr. Changan Guo is a leading surgical oncologist whose research focuses on advancing minimally invasive techniques for the treatment of advanced gastric cancer. His major contributions center on systematically evaluating the safety and efficacy of robotic-assisted gastrectomy compared to traditional laparoscopic approaches. Dr. Guo is best known for his landmark 2018 study, which used the rigorous Clavien–Dindo classification to compare complication severity and incidence between robotic and laparoscopic procedures in over 65 cited works. This work, along with his subsequent 2019 analysis specifically assessing robotic-assisted total versus distal gastrectomy, has provided critical evidence that robotic surgery can be performed safely for advanced disease, despite the technical challenges of total gastrectomy. By employing propensity score matching to reduce selection bias, Dr. Guo’s research has offered surgeons reliable data to guide operative decision-making. His findings have helped establish benchmarks for postoperative outcomes and have influenced the adoption of robotic platforms in complex gastric cancer surgery, making him a respected voice in the field of surgical oncology.
