M.D. Professor Etsuro Hatano
We provide surgical and multidisciplinary treatment for hepatobiliary and pancreatic diseases. We provide the best treatment even for patients with advanced cancer that has been diagnosed as unresectable at other hospitals. In standard surgery, we perform minimally invasive laparoscopic surgery. Our institution is one of the top centers for liver transplantation, and also provides liver transplantations for unresectable cholangiocarcinoma. Our goal is to train surgeons with advanced skills both for surgery and basic research, based on our belief that knowledge, skill, and heart are the key to supporting patients’ hopes.
Research and Education
We are conducting a wide range of research in the field of hepatobiliary-pancreatic oncology and regenerative/transplantation medicine with a view to providing feedback to clinical practice.
- Development of artificial bile ducts using artificial materials.
- Development of hybrid artificial livers that can be recellularized by human hepatocytes after decellularization of livers from different species of animals11．
- Induction of hepatic differentiation of ES cells, iPS cells, and hepatic stem/progenitor cells as a cell source.
- Mechanisms and countermeasures of chemotherapy-induced liver injury.
- Research on the the origin and function of fibroblasts in liver fibrosis, liver regeneration, and cancer.
- Mechanism of severe pancreatic fistula2．
- Development of improved methods for islet transplantation.
- Liver transplantation
- Mechanisms of immune tolerance.
- Reduction of graft injury by controlling complement activation3．
- Development of a new graft preservation method using hydrogen and machine perfusion.
- Research to overcome the small-for-size syndrome by “making small grafts bigger” in xenotransplanted animals4．
- Medical-engineering collaboration
- Development of a medical instrument (MIPS) that enables real-time fluorescent navigation surgery5
(A) A hybrid artificial liver in which hepatocytes (Hep) and liver sinusoidal endothelial cells (LSEC) are recellularized on a decellularized liver scaffold. The recellularization of LSECs suppressed thrombus formation (B), enabling extracorporeal blood circulation for more than ten hours (C).
(A) (A) Posterior segmentectomy of liver. The posterior Glissonean branch was clamped, followed by systemic administration of indocyanine green. By projecting the fluorescent area onto the surgical field with MIPS, the residual liver was demonstrated as a blue area. (B) Real-time fluorescence navigation surgery is possible during the liver resection.
