About
Sejin Lee is a surgical oncologist whose research focuses on minimally invasive and robotic approaches to gastric cancer treatment, with particular expertise in gastrectomy techniques, lymphadenectomy, and surgical education. Based at a high-volume center, Lee has made significant contributions to advancing robotic surgery as a viable and superior alternative to conventional laparoscopic methods, accumulating over 110 citations across his published work. Lee's most influential study, garnering 32 citations, rigorously compared open, laparoscopic, and robotic gastrectomy with D2 lymphadenectomy in obese patients — a technically demanding population — helping to clarify the clinical merits of each approach. His landmark analysis of 2,000 consecutive robotic gastrectomy patients (21 citations) established meaningful long-term survival and outcomes data that the field had previously lacked. His contributions to reduced-port robotic surgery, including novel intracorporeal anastomosis techniques, reflect a commitment to refining precision and minimizing surgical invasiveness. Beyond technical innovation, Lee engages in national-scale epidemiological work through the Korean Gastric Cancer Association's nationwide surveys, shaping policy-relevant insights across South Korea. His recent involvement in the KEROS simulation training program further underscores his dedication to elevating robotic surgical education for the next generation of surgeons.
