Introduction: A polyp is defined as any mass protruding into the lumen of any hollow viscus.They are classified

histomorphologically as neoplastic and non neoplastic polyps.The neoplastic polyps are of great concern because they harbour a

malignant potential which represents a stage in the development of colorectal cancer.The adenoma carcinoma sequence can be

interrupted by the simple out patient procedure of Colonoscopic Polypectomy.Study on colorectal polyps in Tamilnadu is scanty.

Aims and objectives:The aim of this study is to analyse the demography and histomorphological spectrum of colorectal polyps in

our region.

Materials and methods: A 5 year Retrospective study from January 2013 to December 2017 was conducted in a tertiary care

hospital,Salem district,Tamilnadu. The age and sex of the patient,site of occurrence , size of the polyp and histopathological

report of 172 patients were analysed.

Results: Out of 172 cases,119 were non neoplastic polyps and 53 were neoplastic polyps. 84% of patients in our study

population were above the age of 40years.Tubular adenoma was the most commonly diagnosed neoplastic polyp.13 out of 20

cases of polyps with high grade dysplasia,measured >1 cm in diameter.Left sided polyps outnumbered right sided ones with

sigmoid colon being the most commonly involved site.

Conclusion: Screening colonoscopy helps to detect incidental colorectal polyps and interruption of adenoma carcinoma

sequence through Colonoscopic Polypectomy helps to reduce the morbidity and mortality of colorectal malignancy.
