Abstract:
4219 subjects were screened for colorectal cancer by fiberoptic sigmoidoscopy.5 subjects(0.12%)werc found to have cancers: 2 Dukes A, 2 Dukes B, and 1 Dukes C. One or more polyps in 160 subjects (3.79%) were detected, of which 86 were adenomas and 3 severe dysplasia. All the polyps were removed by means of endoscopic polypectomy.For selected screening in small population,fiberoptic sigmoi-doscopy is recommended. As for mass screening, it is advisable to run fecal occult blood test (FOBT) first. All persons with positive FOBT or negative FOBT but belonging to high-risk category should be advised to have fiberoptic sigmoidoscopy. Special diet is unnecessary prior to sigmoidoscopy. Glycerol enema is recomended for bowel preparation.
