Department of Pathology


The Liver and Pancreaticobiliary Pathology Division is led by Dr. Wei Chen, and faculty members include Drs. Wendy Frankel (Department Chair), Martha Yearsley, Shaoli Sun, Ashwini Esnakula, Giovanni Lujan and Wegahta Weldemichael. Our OSU main Campus clinical volume for the Hepato-Pancreato-Biliary Pathology Division was 1829 specimens in the year 2020. This includes 1212 liver specimens, encompassing medical, neoplastic and transplant liver biopsies, liver resections plus outside consultations. Pancreaticobiliary specimens includes ampullary/bile duct biopsies (126), pancreatic biopsies (33), and pancreatectomy specimens (458). We continue to provide excellent clinical service to our gastroenterologists, HepatoPancreaticoBiliary and transplant surgeons.

In addition to clinical activities, we are dedicated to our teaching mission. We offer a combined GI/Liver/Pancreaticobiliary Pathology Fellowship under the direction of Dr. Frankel and Dr. Chen. We are also involved in teaching gastroenterology fellows, hepatology and transplant surgery fellows, GI and liver pathology fellows, pathology residents and medical students. Our biweekly Liver Clinicopathologic Correlation Conference provides a robust learning tool and well-rounded experience for our fellows. This conference is selected from an array of cases (~ 150 cases per year), and provides an excellent clinicopathologic correlation input to those in attendance. Our Division actively supports ongoing translational research in collaboration with the Hepatology, Transplant Surgery, Radiology and Imaging, and Oncology Departments.
