University of Nebraska Medical Center

Our Fellowship Programs

We offer three fellowship programs: Gastroenterology, Transplant Hepatology and Advanced Endoscopy.

Professional associations with radiology, pathology and pediatric gastroenterology add to our well-rounded program. Experience in surgical approaches to gastrointestinal diseases is provided through our close relationship with members of the Department of Surgery; in particular our fellows are involved in an active liver transplant program.
