Hepato-Pancreato-Biliary (HPB)

About Us

Stanford’s Hepato-Pancreato-Biliary (HPB) surgeons have specialty-training and focused expertise in the care of tumors of the liver, pancreas, and bile duct, as well as non-cancerous conditions such as pancreatitis and complex gallbladder and bile duct disorders. The team performs a high volume of laparoscopic and robotic HPB resections, including complex operations such as major liver resection (hepatectomy) and the Whipple pancreaticoduodenectomy. Many tumors that are resected via traditional open surgery at other hospitals can be removed via these minimally invasive techniques by the Stanford HPB team, resulting in less discomfort and faster recovery.  They have nationally and internationally recognized expertise in the field, and are thus leaders internationally in the training of surgeons to perform these highly technically demanding operations. The HPB surgeons at Stanford routinely are able to tackle tumors that have been deemed “unresectable” elsewhere, using innovative approaches and complex vascular and anatomic reconstruction to allow tumors to be removed while protecting vital anatomy and post-operative quality of life.  As a result of their high volume and vast experience, the Stanford HPB team has outstanding outcomes when compared to similar academic centers.  The Stanford HPB surgeons lead the specialized Hepatobiliary Tumor Board within the Stanford Cancer Institute, partnering with medical oncologists, radiation oncologists, interventional radiologists to map the individualized multidisciplinary treatment plans.
