Gastrointestinal Pathology

image image image

Our gastrointestinal (GI) pathology experts provide rapid and high-quality diagnostic histopathology on gastrointestinal endoscopic biopsies and resections of the gastrointestinal and pancreatico-biliary systems.

Our large-volume services help clinicians provide the most appropriate care for benign or malignant disease, congenital and inherited disorders, trauma and iatrogenic injury. Many specimens are derived from endoscopic biopsies performed by UC Irvine Health gastroenterologists at the H.H. Chao Comprehensive Digestive Disease Center. These include major conditions such as Barrett's esophagus, chronic gastritis, ulcers, celiac disease, polyps, inflammatory bowel disease, benign and malignant tumors, including lymphoma and carcinoma.  

Services are available in the following areas:

  • Consultation services for problematic and unusual cases
  • Early detection of hereditary neoplasia
  • Immunohistochemistry
  • Molecular studies for gastrointestinal malignancies, including carcinoma, lymphoma and sarcoma
  • Rapid diagnosis of biopsy specimens
  • Electron microscopy

Educational opportunities include:

Research

  • Our research involves esoteric colorectal morphology and diagnostic pitfalls. Some of our past projects have studied pulse granulomas, three-dimensional histology and colorectal stents. Topics of our current projects include colorectal polyps, colonic inertia and colorectal anatomy.
