Is histological investigation of polyps always necessary?
A small right-sided polyp in a young patient is associated with a small risk (3.8 %) for advanced adenomatous tissue, indicating that histological investigation of such a polyp might not always be necessary. However, the recent recognition of flat adenomas and "mini" de novo colon carcinomas in the European population also may limit the usefulness of small polyp diameters in the exclusion of severe polyp histology.
The frequency of the genotype IL-6 174GG and allele G was different between healthy and ill groups. Therefore, this genotype may be a common risk factor for both CP and PID in Brazilian populations.
