Aim: To evaluate the predominant colorectal polyps in the Almadinah region of Saudi Arabia. Materials and
Methods: In this iretrospective study, we analyzed pathology reports of colonoscopies performed in King FahadHospital, Madinah, Saudi Arabia during the period 2006 to 2013. Data based on patient age, gender, size, siteand type of polyps and the degree of dysplasia were analyzed by software SPSS 17 and compared with otherpublished studies from different geographic regions of the world.
Results: During these years, 224 patients hadcolonic polyps, of whom 149 (66.5%) were men and 75 (33.5%) were women. The most common types of polypswere adenomatous (166), followed by hyperplastic polyps (24), juvenile (18), inflammatory (13), lipomatous(2) and one patient with Peutz-Jegher polyps. Tubulovillous adenoma was the commonest adenomatous polyp(102), followed by tubular (41) and villous (23) types. The sigmoid colon was the most commonly involved region(36.6%). Dysplasia was significantly associated with female patients who had large size tubulovillous polypslocated in the left colon.
Conclusions: The type and distribution of colorectal polyps in Saudi Arabia is verysimilar to Western countries. Patient gender, and size, histological type and location of polyps are closely relatedto dysplastic change in colonic polyps.
