Comparative analysis to colorectal polyps of elder and the other patients

Objective: To retrospectively analysis the colorectal polyp difference of elder and other patients. Methods: Data on a total of 820 patients （900 polyps） who had undergone polypectomy between 1997 and 2001 at PLA General Hospital were collected. The difference of colorectal polyps of elder and other patients was assessed by Stata 4.0. Results: The differences （not include juvenile polyps） on sex of patients,sessile or pedunculated polyps,mucosal pathological changes,size and location of polyps,and grade of dysplasia were statistically significant. Canceration or dysplasia rat of polyp with normal mucosa was significantly different between elder and the other patients. Size,histology,sessile or pedunculated and mucosal pathological changes were the major independent polyp risk factors associated with canceration or dysplasia in both elder and other patients （not include juvenile and Peutz-Jeghers polyps）. Conclution: there are some differences of polyps between elder and the other patients,but the major independent polyp risk factors associated with canceration or dysplasia are the same.
