About

Shuangyi Ren is a leading surgical oncologist whose research focuses on advancing minimally invasive techniques for gastric and rectal cancer treatment, particularly through robotic-assisted surgery. Ren’s major contributions center on comparing the oncological outcomes of robotic versus laparoscopic gastrectomy and total mesorectal excision (TME), with a landmark 2024 study on 3,599 patients demonstrating the short-term and three-year benefits of robotic gastrectomy (23 citations). This work, alongside a meta-analysis of D2 gastrectomy outcomes (10 citations), has helped establish robotic surgery as a viable, often superior alternative in complex cases. Ren also pioneered the ALBS method for esophagojejunostomy and developed a nomogram to predict surgical difficulty in laparoscopic TME, highlighting the technical advantages of robotic approaches. With over 70 citations across their top papers, Ren’s research has significantly influenced surgical practice, particularly for elderly patients and those with difficult anatomical conditions. Their multicenter studies and propensity score analyses provide robust evidence for the safety and efficacy of robotic-assisted procedures, making Ren a key figure in the evolution of precision oncologic surgery.
