About
Ivan En‐Howe Tan is a leading health economist and surgical outcomes researcher whose work focuses on the comparative cost-effectiveness of minimally invasive surgical techniques. His major contributions lie in systematically evaluating the economic efficiency of open, laparoscopic, and robotic approaches across multiple surgical specialties, including colorectal, liver, and pancreatic surgery. Tan’s landmark 2023 systematic review and Bayesian network meta-analysis on colorectal surgery (36 citations) provides critical evidence on the cost-benefit trade-offs of robotic and laparoscopic techniques versus traditional open surgery. His 2024 meta-analysis on liver resection (36 citations) similarly offers rigorous economic comparisons, while his propensity score-matched analysis of transanal total mesorectal excision with delayed coloanal anastomosis (TaTME-DCAA) for low rectal cancer (11 citations) demonstrates his ability to integrate clinical outcomes with cost data. Tan’s work is particularly notable for its methodological rigor, employing advanced network meta-analyses to synthesize evidence from randomized trials. His research directly informs surgical decision-making and healthcare resource allocation, making him a key voice in the ongoing debate about the value of robotic surgery. With over 90 cumulative citations in just two years, Tan’s scholarship is rapidly shaping the field of surgical health economics.
