BACKGROUND: In Western countries, colonic polyps are usually adenomatous in nature, are evenly distributed along the entire colon in asymptomatic per-sons and show a left-sided predominance in symptomatic patients. There is dearth of such literature from India. METHODS: We retrospectively analyzed reports of colonoscopies done in our institution during the period 2001 to 2005. Clinical features, colonoscopic description and histologic findings of all patients with polyps were noted. Association of the degree of dysplasia with the size, site and type of polyps and the person's age was assessed. RESULTS: Polyps were seen in 124 (5.1%) of 2412 complete colonoscopies. Mean age of patients with polyps was 58.1 (SD 19.9) years; ninety were men. A majority of polyps (92%) were located in the left colon. They were adenomatous in 99 (79.8%), juvenile in 12 (9.8%), hyperplastic in 11 (8.8 %), inflammatory in 1 (0.8%) and Peutz-Jegher's polyp in 1 (0.8%). Dysplasia was severe in large (>2 cm) polyps compared to small (< 1 cm) ones (p< 0.001). Age of patient and location of polyp had no association with degree of dysplasia. CONCLUSIONS: In southern Indian adults, most colonic polyps are adenomatous and are in the left colon. Large polyps are associated with severe dysplasia.
