Biopsy Artifacts and Iatrogenic Injury To The Gastrointestinal Tract


Many medications result in GI tract injury. Some medications associated with injury can be recognized rather specifically (Yttrium,sodium polystyrene sulfonate, sevelamer, lanthanum), others result in mitotic arrest (taxanes, colchicine) and others result in injury that mimics human disease (olmesartan, various monoclonal antibodies, mycophenolate). Certain biopsy artifacts and NSAID-associated injury are also discussed.

Originally presented on February 11, 2015, in Park City, Utah.
