Transplant hepatology is the field of medicine that deals with liver transplants. A hepatologist is a physician who specializes in diseases and disorders of the liver. This specialist may coordinate treatment with a transplant surgeon for a patient who requires a liver transplant due to liver disease or liver failure. During transplant surgery, the diseased liver is removed and a new liver is placed in the same location. This surgery is done through a large incision in the upper abdomen, and is performed under general anesthetic in a hospital.

Doctor density varies by specialty and location. Massachusetts has 10 practicing transplant hepatologists. Broken out by city, transplant hepatology doctor density in Boston is 5, in Brookline is 1, in Burlington is 1, in Fall River is 1, in Jamaica Plain is 1, in Newton is 1, and in Worcester is 2.
