About
Dr. Longwei Cheng is a leading colorectal surgeon whose research focuses on advancing surgical techniques for rectal cancer, particularly through rigorous comparisons of robotic and laparoscopic approaches. His most impactful contribution is the landmark REAL trial (Robotic versus Laparoscopic surgery for middle and low rectal cancer), a multicenter randomized controlled trial that has reshaped clinical practice. The trial’s short-term outcomes, published in 2022 and cited over 450 times, demonstrated the safety and feasibility of robotic surgery, while his subsequent 2024 and 2025 publications provide critical long-term oncological data, including 3-year locoregional recurrence rates. Dr. Cheng’s work extends to nationwide retrospective studies characterizing robotic colorectal surgery in China, and he has explored nuanced factors like the influence of surgical start time on operative quality. With cumulative citations exceeding 550, his research provides the highest level of evidence for surgeons debating robotic versus laparoscopic techniques. Dr. Cheng’s REAL trial is widely recognized as a pivotal study, offering definitive answers on surgical quality and long-term outcomes for middle and low rectal cancer, making him a key figure in evidence-based surgical oncology.
