Patients experiencing great outcomes with robotic Whipple procedure

A less-invasive surgery option is now available for Hepato-Pancreato-Biliary (HPB) and pancreatic cancer patients at UCHealth. Dr. Joshua Tierney, a UCHealth surgeon in northern Colorado, offers robotic Whipple procedures for qualifying patients. The robotic procedure is equivalent to an open Whipple procedure but with added benefits. Also known as pancreaticoduodenectomy, the Whipple procedure involves removing the head of the pancreas, duodenum, distal bile duct and gallbladder. The traditional method of this specialized surgery involves cutting open the abdomen to get to the pancreas. The less-invasive robotic Whipple procedure involves five tiny incisions in the abdominal area to access the pancreas. UCHealth patients who have had robotic surgery have shorter hospital stays, a faster recovery, less surgical pain and reduced narcotic dependency. Good candidates for robotic procedure are those patients with a low BMI and smaller tumors. Dr. Tierney is the only UCHealth surgeon providing the robotic Whipple procedure in northern Colorado. He is fellowship-trained in HPB surgery and interventional endoscopy. He earned his medical degree from Indian University School of Medicine, completed his residency in general surgery at Vanderbilt University, and his fellowship at the University of Louisville.
