Hepatologists specialize in the study of the liver. The hepatologist will diagnose, treat and care for patients who have disorders of their liver, gallbladder or bile ducts. A team approach is used in the Hepatobiliary Clinic. In addition to the hepatologist, this team may include a desk clinical assistant, secretary, nurse, physician assistant or fellow. The team may also include a radiologist (a doctor specialized in imaging the liver), oncologist (a doctor specialized in the treatment of liver cancer), a pathologist (a doctor specializing in evaluating biopsy specimens), or hepatobiliary surgeons. One goal of the Hepatobiliary Clinic is to provide the patient with a thorough, yet timely, cost-effective evaluation of his or her liver disorder.
