About

Masatoshi Kajiwara is a pioneering surgical innovator whose research sits at the forefront of robotic liver surgery, with a particular focus on solving one of the field's most persistent technical challenges: safe and effective liver parenchymal transection. Recognizing the limitations of existing robotic instrumentation, Kajiwara has dedicated his work to developing and refining novel transection techniques that make complex hepatic procedures more precise and reproducible in robotic settings. His most influential contribution is the introduction of saline-linked energy devices for robotic liver resection. His 2022 paper introducing the Saline-Linked Cautery Scissors (SLiC-Scissors) technique has accumulated 14 citations, signaling rapid uptake within the surgical community. Building on this, his 2023 work describing the saline-linked bipolar clamp-crush technique — which elegantly prevents tissue adherence during resection — has already gathered 9 citations. Most recently, he has extended these innovations to major hepatectomy procedures, applying the Glissonean approach alongside his bipolar technique in robotic left hepatectomy. Kajiwara's work is reshaping the technical landscape of minimally invasive liver surgery, offering surgeons practical, reproducible solutions that promise improved patient outcomes and broader adoption of robotic hepatectomy worldwide.
