The two-year Abdominal Transplant Surgery Fellowship at Mayo Clinic's campus in Phoenix/Scottsdale, Arizona, provides education, surgical experience, and clinical training in all aspects of multi-organ abdominal transplant and the care of transplant patients. 

This fellowship provides a comprehensive training experience for individuals focused on attaining expertise in a modern multi-organ transplant program. We aim to train future leaders in transplant surgery around the world.

We have a comprehensive abdominal transplant program including liver transplantation (deceased donor and living donor transplants), kidney transplantation (deceased donor and living donor transplantation), pancreas transplantation, and hepatobiliary and pancreas surgery. 

Our fellows graduate in the highest percentiles for individual case volume in the nation. In 2022, Mayo Clinic surgeons at the Arizona campus performed approximately 250 liver transplants, 475 kidney transplants, and 30 pancreas transplants. We have been the largest abdominal transplant program in the U.S. by volume for several years and have maintained strong outcomes as measured by the Scientific Registry of Transplant Recipients.

As a fellow, you will train in a supportive faculty environment with abundant opportunities for clinical and academic development. Fellows will be well prepared to enter a career performing liver, kidney, and pancreas transplantation, organ procurement, research, and administrative skills essential to success in the modern transplant surgery environment.
