About
Dr. Wanguang Zhang is a pioneering hepatobiliary surgeon whose research centers on advancing minimally invasive liver surgery, particularly through the comparative analysis of robotic and laparoscopic techniques. His major contributions lie in rigorously evaluating the safety, efficacy, and optimal applications of robotic-assisted liver resections across various clinical scenarios. Through landmark propensity-score matched and coarsened-exact matched analyses, Dr. Zhang has systematically compared robotic versus laparoscopic approaches for major hepatectomies, limited resections of the challenging posterosuperior segments, and minor resections of the anterolateral segments—amassing over 260 citations across his top-cited works. His 2018 study on the learning curve in robot-assisted laparoscopic liver resection (75 citations) and his foundational work on intraoperative ultrasonography during robotic hepatectomy have helped define best practices. Notably, Dr. Zhang has also investigated the critical impact of liver cirrhosis severity and portal hypertension on surgical difficulty and outcomes, providing essential guidance for patient selection. His recent establishment of global benchmarks for robotic liver resections (2025) represents a significant step toward standardizing quality metrics in this rapidly evolving field.
