About
Felix Krenzien is a hepatobiliary surgeon and clinical researcher whose work sits at the cutting edge of minimally invasive liver surgery. His research focuses primarily on comparing robotic and laparoscopic approaches to hepatectomy, spanning the full spectrum of procedural complexity — from limited resections of technically demanding posterosuperior segments to major hepatectomies such as right, extended right, and left lateral sectionectomies. Krenzien has made significant contributions through large-scale, international multicenter studies employing rigorous propensity score-matched analyses, lending his comparative findings a level of methodological credibility rarely achieved in surgical research. His most cited work (120 citations) established critical benchmarks for robotic versus laparoscopic right and extended right hepatectomy, while subsequent studies have collectively amassed hundreds of citations across multiple procedural categories. Notably, his 2022 single-center analysis of 600 consecutive patients offered a rare longitudinal perspective on the adoption and refinement of robotic liver surgery in routine practice. A recurring theme across his portfolio is patient safety and surgical learning — exemplified by his innovative complexity-adjusted learning curve analysis, which acknowledged the procedural heterogeneity often overlooked in surgical training research. Through prolific international collaboration, Krenzien has helped reshape evidence-based standards for minimally invasive hepatic surgery worldwide.
