Aim : To study the prevalence,histopathological types and pattern of distribution of colonic polyps in a cohort of patients evaluated in our tertiary care centre. Materials and Methods : Data of patients undergoing colonoscopy between 2017-2018 for various abdominal complaints were analysed retrospectively for presence of colonic polyps.Age , gender, clinical symptoms and histopathological analysis were also included in the study.Statistical analysis was done using SPSS 23.0 version to arrive at correlations between pattern of distribution and histopathological types. Results : A total of 1423 Colonoscopies were done during the 2 year period. Of them 152 cases were found to have Polyps including few patients with multiple polyps and overall a total of 207 Polyps were studied.Mean age of the study population was 57.61 years and most of them were males (77.6%).Polyps were more commonly located in rectum (20.3%) and sigmoid (25.1%).Most of the polyps were smaller in size <1cm (75.8%) and only few were >2cm (6.3%).Sessile polyps (77.3%) were more common then pedunculated (22.7%).Histology showed Adenomatous (63.7 %) followed by Hyperplastic (28%) and serrated (6.3%) were most common variety.Around 5.8% of polyps had high grade dysplasia and was more commonly seen in tubulovillous adenomas then tubular adenomas and also amongst serrated polyps. Conclusion : Colonic polyps were noted in around 10 % all colonoscopies and are less common in south Indian population then their western counterparts,however similar to west adenomatous polyp is the most predominant type of histology.Larger polyps and polyps with villous component and serrated polyps have more chances of having high grade dysplasia
