Management of colorectal adenoma: a Singapore experience.

The racial distribution and pathology of 115 colorectal polyps from 72 patients were analysed. There were 88 (77%) adenomas. 90.9% of these were from Chinese and none from Malay patients. 79% were found in the sigmoid colon and rectum. The racial and site distributions of adenomas reflect the patterns of carcinoma seen in Singapore. The management of adenoma was discussed. Annual surveillance for high-risk and three yearly surveillance of low-risk patients up to an arbitrary age of 75 years is recommended.
