Biography
Dr. Hobart W. Harris is an expert in treating surgical infections, diseases of the pancreas and biliary system and abdominal wall hernias, including pancreas, gallbladder and bile duct cancer, acute and chronic pancreatitis, islet autotransplantation for chronic pancreatitis, complex gallstone disease, intra-abdominal sepsis, serious infections of the skin and soft tissue, and enterocutaneous fistulas. He treats patients with complicated and often life-threatening conditions through the Complex Abdominal Surgery Program. Dr. Harris is also a pioneer and leader in the management and repair of complex ventral (incisional) hernias. Specifically, he is an expert at repairing gigantic ventral hernias, where closure of the defect and reconstructing the abdominal wall requires advanced techniques, such as progressive pneumoperiteum whereby the abdominal wall muscles are first stretched prior to repairing the hernia.
Dr. Harris earned his undergraduate, medical and public health degrees at Harvard University, before completing an internship and residency in general surgery at UCSF. After residency training, he completed a fellowship in Hepatobiliary Surgery at the University of Hong Kong, Queen Mary Hospital before joining the faculty at UCSF in 1994. Harris is a Fellow of the American College of Surgeons and is a member of numerous surgical and scientific societies including the American Surgical Association.
