Hepatobiliary and Pancreatic Surgery

City of Hope's Hepatobiliary and Pancreatic Surgery Service offers the latest treatment for patients with primary and metastatic cancers of the pancreas, liver, gallbladder and bile duct. We have one of the most experienced hepatobiliary and pancreatic surgery teams in the United States. Our surgeons have performed thousands of procedures, and we frequently treat patients whose tumors are considered inoperable at other facilities. We also work continuously to improve the effectiveness and reduce complications of surgery and are at the forefront of developing minimally-invasive procedures.
