Diseases of the colon and rectum
-
Inflammatory bowel disease (IBD) is associated with an increase in colon and rectal carcinoma. Immunosuppression after transplantation increases the incidence of certain types of tumors. ⋯ There is a subset of transplant patients with primary sclerosing cholangitis and IBD who rapidly develop colorectal neoplasms. Frequent surveillance is recommended for IBD patients in the post-transplant period.
