Zhengyan Li

About

Zhengyan Li is a prominent surgical oncologist whose research has fundamentally advanced the understanding of robotic surgery for gastric cancer. Specializing in minimally invasive gastrectomy, Li has dedicated his career to rigorously comparing robotic gastrectomy (RG) with laparoscopic gastrectomy (LG) across multiple clinical dimensions, including short-term outcomes, long-term oncological efficacy, and procedural safety. His landmark multicenter retrospective cohort study comparing RG and LG (2021, 94 citations) stands as one of the field's most influential contributions, providing large-scale evidence that has shaped surgical decision-making globally. Complementing this work, his investigation into the learning curves of robotic distal and total gastrectomy (2021, 62 citations) offered practical guidance for surgeons adopting these technically demanding procedures. Li's research portfolio spans specialized patient populations, including those with remnant stomach carcinoma and esophagogastric junction tumors, demonstrating remarkable breadth. With over 280 cumulative citations, his body of work has meaningfully informed international clinical practice guidelines and surgical training programs. His decade-long institutional experience, reflected in analyses of more than 800 robotic procedures, underscores his standing as a leading voice in the evolution of robotic gastric cancer surgery.
