PURPOSE: The risk, prevention, and treatment of colorectal neoplasia in inflammatory bowel disease (IBD) are still a matter of debate. The aim of this study was to analyze the occurrence of colorectal neoplasia in IBD patients who underwent proctocolectomy. METHODS: The study population comprised of 123 IBD patients who underwent proctocolectomy because of neoplasia, therapy refractivity, or complications between January 2000 and July 2011. RESULTS: One hundred fourteen (92.7%) patients were pre-operatively diagnosed with ulcerative colitis, 5 (4.1%) with colitis indeterminata, and 4 (3.3%) with colonic Crohn's disease. Colectomy was indicated in 39 (31.7%) patients because of a neoplasia, in 68 (55.3%) because of a refractory course of the disease, and in 16 (13.0%) because of complications. Neoplasia was found in 36 patients on a histopathologic evaluation of the colectomy specimens. Ten (8.1%) patients post-operatively showed a pre-operatively not described advanced neoplasia. In three (2.4%) of these patients, the detection of advanced neoplasia (two high-grade intraepithelial neoplasias (IENs), one carcinoma) was a complete de novo finding. Carcinoma had not been diagnosed pre-operatively in six (4.9%) patients. A multifocal distribution of neoplasia was seen in 66.7% of patients with neoplasia. The median duration of disease was 15.5 years in case of neoplasia opposed to 6.0 years in those without neoplasia detection. CONCLUSION: Our data demonstrate a high rate of pre-operatively undetected high-grade IENs and carcinoma and a frequent multifocal occurrence in IBD patients with long-standing inflammation of the colon. This should be kept in mind for treatment decisions particularly in patients with a chronic refractory course of the disease.
