Artificial Organ and Transplantation Surgery

The Department of Artificial Organs and Transplantation Surgery specializes in living and cadaveric donor liver transplantation for patients with end-stage liver disease, for which careful management and a team approach involving various clinical departments are required.

Medical services

A team of specialists in liver transplantation provide medical services both in the outpatient clinic and inpatient wards. There are also coordinators from the Organ Transplantation Center to support donors in dealing with their problems and address other issues specific to organ transplant. The physician attending the patient during hospitalization will generally be responsible for postoperative outpatient treatment.

Diagnosis and treatment policy

Our motto is “to perform highly advanced, safe, and successful liver transplants.” With this motto, the department staff carefully discusses and reviews each case daily to achieve good outcomes.


Living donor partial liver transplant

The Transplantation Surgery Department of the University of Tokyo Hospital performed the first living donor liver transplant in Japan on January 31, 1996. As of December 2022, the number of patients undergoing living donor liver transplant at this hospital reached 798, including 714 adults and 78 children. This is the third largest number of liver transplants in Japan. The survival rate for liver transplant at this hospital is higher than the national average by about 10%. The 1-, 3-, and 5-year posttransplant survival rates are 93%, 89% and 85%, respectively (as of December 2022).

Brain-dead donor liver transplantation

There have been 738 cases of liver transplants from brain-dead donors in Japan. Our Hospital, designated as a hospital for liver transplants from braindead donors, has successfully performed 59 liver transplants from braindead donors.

  • Auxiliary Partial Orthotopic Liver Transplantation (APOLT) and Domino Liver Transplantation is also performed.
  • Indications for liver transplantation

    Biliary atresia, metabolic liver disease, Wilson’s disease, citrullinemia, familial amyloid neuropathy, fulminant hepatitis, viral (type B and C) decompensated cirrhosis, primary biliary cholangitis, primary sclerosing cholangitis, alcoholic and non-alcoholic steatohepatitis, chronic cholestasis, primary hepatocellular carcinoma (insurance coverage is within the Milan criteria or 5-5-500 criteria, less than 5cm in diameter and less than 5 in number is our indication for living donor liver transplantation (Tokyo criteria)), etc.
