The Department of Pathology offers one-year fellowships in Gastrointestinal & Hepatobiliary Pathology. The fellowship provides a primary role in diagnosis of adult and pediatric gastrointestinal, liver, pancreas and the biliary tract disease. The consultation service receives ~2000 outside consultations (~60-70% medical and neoplastic liver, 30-40% tubular GI, pancreas, and hepatobiliary) and the fellow serves as a consultant for our busy in-house gastrointestinal, liver, and transplant services. UCSF has large pediatric/adult IBD centers and is a renowned liver transplant center and so provides especially rich diagnostic material in these areas. Fellows also participate in multidisciplinary clinical conferences, including liver transplant, hepatology/gastroenterology conferences, pediatric gastroenterology conference, as well as other ad hoc conferences pertinent to the Liver/GI cases. There are numerous research opportunities and the service extensively uses cutting edge immunohistochemistry and molecular techniques. Rotations are available at Moffitt Hospital and the VA Medical Center; an elective endoscopy experience is available at the VA.

Additional years of post-doctoral level training may be available for qualified candidates with an interest in basic research into questions related to hepatobiliary & gastrointestinal disease.

Candidates who are also interested in general surgical pathology training, in addition to Liver/GI subspecialty training, may be offered a two year combined clinical training experience (please see our surgical pathology fellowship webpage for more details), which may allow for limited independent sign out experience during the second year.
