About

Dr. Yanan Zhen is a leading figure in minimally invasive colorectal surgery, with a focused expertise in comparing robotic and laparoscopic techniques. Her seminal 2014 meta-analysis, "Robotic versus laparoscopic right colectomy," which has garnered 86 citations, stands as a foundational work in the field. In this study, Dr. Zhen systematically evaluated the clinical safety and efficacy of robotic right colectomy (RRC) against conventional laparoscopic right colectomy (LRC), providing critical evidence that has shaped surgical decision-making. By synthesizing data from comparative studies, she highlighted key perioperative outcomes, offering surgeons a data-driven framework for choosing between these advanced approaches. Her work has not only clarified the relative benefits of robotic assistance—such as enhanced dexterity and visualization—but also underscored areas where laparoscopy remains competitive. Through this rigorous analysis, Dr. Zhen has made a lasting impact on colorectal surgery, guiding both clinical practice and future research. Her contributions continue to influence how surgeons optimize patient outcomes in minimally invasive colectomy, making her a respected voice in the ongoing evolution of surgical technology.
