About

Mamoru Morimoto is a pioneering hepatobiliary and pancreatic surgeon whose work is redefining the boundaries of minimally invasive organ-preserving surgery. His primary research focuses on advanced laparoscopic and robotic techniques for complex anatomical liver resections and simultaneous multi-organ tumor excisions. Morimoto’s most significant contribution is the refinement of the Glissonean pedicle isolation technique, guided by the Laennec’s capsule, which has become a cornerstone for safe inflow control in laparoscopic anatomical liver resection. This work, detailed in his 2023 paper (13 citations), directly addresses one of the most critical and challenging steps in minimally invasive liver surgery. Furthermore, he has demonstrated remarkable innovation in managing synchronous gastric and pancreatic tumors. His reports on simultaneous robotic distal gastrectomy and distal pancreatectomy (3 citations) and a subsequent case (2 citations) showcase how indocyanine green fluorescence imaging can be used to assess remnant gastric viability, thereby avoiding total gastrectomy. By proving the feasibility of these complex, organ-sparing procedures, Morimoto is setting new standards for surgical oncology, offering patients reduced morbidity without compromising oncologic outcomes.
