Train at the forefront of GI pathology

The OHSU Department of Pathology and Laboratory Medicine offers a one-year, non-accredited fellowship in gastrointestinal, pancreaticobiliary and liver pathology. You will train across the full spectrum of GI pathology with expert mentorship from program director, Brian Brinkerhoff, M.D. 

Through progressive responsibility, you will build skills in diagnostic and digital pathology and gain experience teaching residents and medical students. Depending on your progress, you may reach independent signout by the end of the year, practicing at an attending level.

Why train with us?

At OHSU, we value educating the next generation of pathologists. Our department has a dedicated Vice Chair of Education, Mandy VanSandt, D.O., who also directs the residency program. This structural investment reflects our department's commitment to teaching. 

As a GI pathology fellow, you will train alongside five subspecialty GI pathologists who manage 7,500 cases a year. You will focus on both GI biopsy and resection, developing expertise in: 

  • Medical and transplant liver pathology, including native and post-transplant biopsies, with access to OHSU’s active liver transplant program
  • Pancreaticobiliary pathology, spanning diagnostic biopsies, complex resection specimens, and intraoperative consultations, including Whipple and distal pancreatectomy cases from the OHSU Knight Cancer Institute
  • Luminal GI tract pathology, high volume of upper and lower GI biopsies, inflammatory bowel disease, and polyposis cases
  • Challenging consultative cases from OHSU’s regional clinical network including the Portland VA Medical Center, OHSU Doernbecher Children’s Hospital, Shriners Hospital, Hillsboro Medical Center and Columbia Memorial Hospital 

Digital pathology

OHSU is one of a few academic programs in the country actively developing digital pathology technology tools. These include integrated whole-slide imaging and AI-assisted clinical workflows. You will work with tools as OHSU expands their use. 

Elective time

You'll have three months of protected elective time for subspecialty rotations, research or other pursuits aligned with your career goals. 

Consulting experience

OHSU trains pathologists to function as clinical consultants, not just report-generators. You will work as a member of the diagnostic team, collaborating with gastroenterologists, surgical oncologists and hepatologists.

You'll also attend and present at tumor boards and clinical conferences, helping shape treatment decisions in real time.

Research

We encourage fellows to pursue research projects. You will have access to a broad clinical dataset, a collaborative faculty and the OHSU Knight Cancer Institute, one of only 57 NCI-designated cancer centers in the country.  

Projects range from retrospective case analyses to prospective outcomes studies. We help you identify work aligned with your interests and career goals

Curriculum

The fellow rotates equally between the GI Biopsy and GI Resection services. Seven pathologist assistants handle the grossing work, so you spend your time doing what a fellowship should prepare you to do: interpreting cases, not preparing specimens. 

GI Biopsy service

  • Esophageal, gastric, and small intestinal biopsies
  • Colorectal biopsies and polypectomies
  • Inflammatory bowel disease: medical and surveillance biopsies
  • Liver biopsies: medical (native) and post-transplant
  • Pancreaticobiliary biopsies and brushings 

GI Resection service

  • Esophageal, gastric, and small bowel resections
  • Colorectal resections, including total proctocolectomy specimens
  • Hepatic resections: primary and metastatic tumors
  • Pancreaticoduodenectomy (Whipple) and distal pancreatectomy specimens
  • Liver explant and transplant pathology
  • Complex gallbladder and biliary tract specimens
