ABSTRACT

In recent years,with the change of lifestyle and environment,the incidence of colorectal cancer is increasing.Colorectal polyp is an important precancerous lesion of colorectal cancer;endoscopic early detection,early diagnosis are important for the prevention and treatment of colorectal cancer.Aims:To investigate the endoscopic findings, pathology and clinical features of colorectal polyps.Methods:Patients with colorectal polyps from January 2014 to June 2016 at the Third People's Hospital of Shenzhen were enrolled,and the general information data,endoscopic findings, pathology and canceration rate were retrospectively analyzed.Results:A total of 740 patients had colorectal polyps detected,the ratio of male to female was 1.751,559 (75.5%)patients were aged >40 years,70.4% of polyps were located in left hemicolon,the main pathological type of polyps were inflammatory polyps (29.0%),hyperplastic polyps (29.6%),tubular adenoma (30.3%).Cancer was found in 38 patients,canceration rate was 5.1%;the main pathological types of cancerated adenoma were tubular adenoma,tubular villous adenoma and villous adenoma,and 87.2%had a diameter greater than 1.5 cm,and were mainly located in left hemicolon (76.9%).Conclusions:Gender,age,pathological type, diameter of colorectal polyps are important factors of canceration.Male colorectal polyps patients with age >40 years, diameter greater than 1 .5 cm,tubular villous adenoma and villous adenoma should be paid attention and followed up.
