Riccardo A. Superina, MD

Dr. Superina is a world-renowned authority in the field of pediatric liver, kidney and intestinal transplantation and an internationally recognized expert in the surgical treatment of complex hepatobiliary conditions, pancreatic disease and endocrine tumors.

Because pediatric transplantation requires rigorous subspecialty training beyond traditional residency and fellowship, Dr. Superina is one of only a handful of pediatric surgeons in the United States with the depth of expertise and scope of training to perform highly specialized transplantation procedures of the intra-abdominal organs in children. Dr. Superina is a leading expert on the a procedure known as the meso-rex bypass, or Rex shunt, a complex liver surgery used to restore venous circulation in a rare condition known as pediatric portal vein hypertension. He has performed more than 200 such procedures — the largest pediatric case series in the world.
