Clinical accuracy in the diagnosis of small polyps using the flexible fiberoptic sigmoidoscope

Abstract

Patients (78) referred to a specialist clinic for investigation of large bowel symptoms were examined with the flexible fiberoptic sigmoidoscope. Of 120 polyps treated, there were 84 adenomatous and 32 hyperplastic polyps. Of the polyps, 69% were situated beyond 18 cm from the anal verge. Endoscopic diagnosis was correct in 82% of the cases. The size of the polyp assessed endoscopically strongly influenced the clinical diagnosis, but proved unreliable as a means of making an accurate diagnosis. Results indicate that, whenever possible, all polyps of all sizes should be removed for microscopic examination.
