About
Kiyoshi Hasegawa is a leading hepatobiliary and pancreatic surgeon whose research has significantly shaped the modern landscape of liver and pancreatic cancer surgery. His work spans surgical oncology, minimally invasive techniques, and multidisciplinary treatment strategies, with a particular focus on optimizing outcomes for patients with hepatocellular carcinoma and other liver malignancies. Hasegawa's most cited contribution, "Advances in the Surgical Treatment of Liver Cancer" (2022, 112 citations), offers a comprehensive synthesis of three decades of progress in liver resection, including critical developments in preoperative remnant liver assessment. His comparative studies on robotic versus laparoscopic liver resections — examining both posterosuperior and anterolateral segments — have provided rigorous, propensity score-matched evidence that is actively guiding surgical decision-making worldwide, accumulating over 50 citations collectively. Beyond technique comparisons, Hasegawa has contributed to establishing benchmark outcomes for open major hepatectomy and investigating the surgical complexities introduced by cirrhosis and portal hypertension. His recent work extends into robotic pancreatoduodenectomy, demonstrating his breadth across hepatopancreatic surgery. With publications across elite surgical journals and growing international collaborative studies, Hasegawa represents a pivotal voice in advancing safe, evidence-based, and minimally invasive approaches to complex abdominal oncology.
