About

Dr. Zhi‐guo Shan is a leading figure in minimally invasive gastric cancer surgery, with a particular focus on the technical mastery and clinical outcomes of robotic gastrectomy. His research has been instrumental in defining the learning curve for robotic distal and total gastrectomy, providing crucial benchmarks for surgical training and safe adoption of this advanced technology. In his landmark 2021 study, cited over 60 times, Dr. Shan analyzed data from five surgeons across two high-volume centers, demonstrating that proficiency in robotic gastrectomy requires approximately 25–40 cases, with distinct phases for distal versus total procedures. This work has directly shaped surgical education and quality assurance protocols worldwide. Beyond this, his broader contributions encompass comparative effectiveness research, optimizing perioperative care, and advancing the evidence base for robotic approaches in gastric cancer. With a citation record that continues to grow, Dr. Shan’s research is essential reading for any surgeon or trainee seeking to understand the path to expertise in robotic gastrectomy.
