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 biliary tract disease. The consultation service receives nearly 2000 outside consultations (60-70% medical and neoplastic liver, 30-40% tubular GI and pancreas). The fellow also coordinates the consultations for challenging cases from in-house gastrointestinal and hepatobiliary as well as the liver transplant services. UCSF has a large pediatric/adult IBD program, and is a renowned liver transplant center, providing rich diagnostic material in these areas. The fellows participate in multidisciplinary clinical conferences, including liver transplant, hepatology/gastroenterology conferences, pediatric gastroenterology conference, as well as other ad hoc conferences pertinent to the hepatobiliary GI cases. There are numerous research opportunities and the service extensively uses cutting edge immunohistochemistry, molecular techniques and sequencing assays. The fellows work at Moffitt and Mission Bay Hospitals; elective experience in endoscopy, molecular pathology and other subspecialties of surgical pathology is available.

Additional years of post-doctoral level training may be available for qualified candidates with an interest in basic research in hepatobiliary & gastrointestinal disease. Candidates who are interested in general surgical pathology fellowship, in addition to GI and hepatobiliary pathology subspecialty training, may be offered a two year combined clinical training experience (see surgical pathology fellowship webpage for details), which may allow for a limited independent sign out experience during the second year.
