Abstract:
BACKGROUND/AIMS: Virtual colonoscopy using abdominal spiral computed tomography scanning allows total colonic evaluation with minimal invasiveness. We compared the performance of virtual colonoscopy and colonoscopy for the detection of colorectal polyps. METHODS: We performed colonoscopy before the virtual colonoscopy. Virtual colonoscopy was performed immediately before the colonoscopic polypectomy in 24 adults (16 men and 8 women: mean age, 59 years). RESULTS: A total of 48 polyps were found by colonoscopy. Virtual colonoscopy identified 20 of 28 polyps that were 10 mm or more in diameter (71%), 3 of 4 that were 6 to 9 mm (75%), and 9 of 16 that were 5 mm or smaller (56%). Overall sensitivity of virtual colonoscopy for colorectal polyps was 67%. CONCLUSIONS: Our result of virtual colonoscopy showed lower sensitivity for detection of significant colorectal lesions than previously reported studies. Further large group study may be needed to determine the usefulness of virtual colonoscopy.
