ABSTRACT
OBJECTIVE:
To show our experience and results in Virtual Colonoscopy (VC). MATERIAL ANDMETHOD:
Five hundred patients with personal or familial history of colorectal carcinoma and/or adenomas, or any kind of coloproctologic symptoms were studied. VCs were practiced using a helical CT scanner (300 patients) and a multislice CT scanner (200 patients) a few hours after Conventional Colonoscopy (CC), considered the gold standard. The patients were evaluated in a prospective blind study, to determine sensitivity and specificity of VC. Findings were classified as 1) normal studies; 2) studies with pathological findings. This one was subdivided into 2a) Lesions below 5 mm., 2b) Lesions between 5-9 mm., 2c) Lesions above 9 mm.RESULTS:
VC detected 253 normal studies whereas CC only detected 233. The sensitivity and specificity for each subgroup were 2a) 87.8% and 86.9%; 2b) 95.6% and 91.4%; 2c) 100.0% and 100.0% respectively.CONCLUSION:
VC is a feasible and useful method for evaluating the entire colon. It is well tolerated, it has no complications and a high sensitivity and specificity for elevated lesions, especially the ones above or equal to 5 mm.
