Dr. Stapfer has been practicing liver and pancreatic surgery for nearly 15 years, building such an outstanding track record that patients have traveled from as far away as Oregon, New Mexico, and Arizona to seek her expertise. She specializes in complex surgical problems, including duodenal perforation and injuries, acute necrotizing pancreatitis, bile duct injuries, and bowel enterocutaneous fistulas. She also has a particular interest in pancreatic cancer, duodenal cancer, neuroendocrine tumors, and cholangiocarcinoma.

In addition to numerous other complex surgeries involving the liver, bile ducts, pancreas, and duodenum, Dr. Stapfer has performed 1200 Whipple and pancreatic surgeries, over 800 liver resections, and over 700 liver transplants. Her experience with liver transplantation has given Dr. Stapfer exceptional proficiency with locally advanced pancreatic cancers that require portal vein and mesenteric artery reconstruction.

In order to offer her patients shorter, more comfortable recoveries, Dr. Stapfer has become highly skilled in laparoscopic techniques for liver resection and pancreatic surgery.

She is board certified in general surgery, hepatobiliary and pancreatic surgery, and abdominal organ transplant.
