  • Title: Sigmoidoscopy as a periodic screening test.
    Author: Dutton JJ.
    Journal: J Fam Pract; 1978 Nov; 7(5):1041-6. PubMed ID: 722261.
    Abstract:
    Available data suggest that routine screening procedures and removal of benign adenomatous polyps in all asymptomatic patients over the age of 40 to 50 years may significantly reduce both mortality and morbidity rates for colorectal carcinoma. Such data show that sigmoidoscopy is a valuable part of any screening program and can be performed at low cost and with minimal risk to the patient. It is concluded that an adequate routine screening program can be achieved with annual stool guaiac examination and sigmoidoscopy every five years between ages 40 and 50, and every three years over the age of 50 in asymptomatic patients. All patients with a history of colonic lesions must be seen more frequently because of the higher risk of recurrence.
