About
Adrian Kah Heng Chiow is a leading hepatobiliary surgeon whose research focuses on advancing minimally invasive liver surgery, particularly through rigorous comparisons of robotic and laparoscopic techniques. His major contributions lie in demonstrating the safety, efficacy, and potential advantages of robotic approaches for complex liver resections. Through a series of landmark international multicenter studies, Chiow has systematically compared outcomes for major hepatectomies, including right and extended right hepatectomies (120 citations), left and extended left hepatectomies (57 citations), and challenging resections of the posterosuperior segments (54 citations). His work consistently employs propensity-score matching to minimize selection bias, providing robust evidence that robotic surgery can reduce blood loss and conversion rates compared to laparoscopy for technically demanding procedures. With over 500 cumulative citations, Chiow’s research has shaped clinical decision-making by clarifying which patients benefit most from each approach. His notable achievements include leading the largest comparative analysis of robotic versus laparoscopic major hepatectomies (59 citations) and identifying risk factors for open conversion in over 3,800 procedures (36 citations). For students and researchers, Chiow’s work exemplifies how methodologically rigorous comparative effectiveness research can guide the adoption of innovative surgical technologies.
