Abstract
Objective: To determine the diagnostic efficiency of multislice computed tomography colonography in detection of colorectal pathologies compared with video colonoscopy.
Material and Methods: In our study, 70 patients who underwent multislice computed tomography colonography and video colonoscopy within an 18-month period were analyzed retrospectively, and multislice computed tomography colonography findings were compared with video colonoscopy findings.
Results: Of the patients, 57.1% were male (n=40) and 42.9% were female (n=30), with a mean age of 52.8 years. A total of 65 pathologies including 39 polyps, 15 colon tumors, 5 ulcerative colitis, 1 angiodysplasia and 1 nonspecific proctosigmoiditis, were detected in 38 patients by video colonoscopy. Of the 39 polyps detected, 31 were ≤5 mm, 4 were 6-9 mm and 4 were ≥10 mm. The sensitivity of multislice computed tomography colonography for detection of all polyps regardless their size was 64.1%, 100% for polyps ≥10 mm, 75% for polyps that are between 6-9 mm and 58.1% for polyps ≤5 mm. The sensitivity was 100% for colon cancers, 75% for diverticulosis and 80% for ulcerative colitis.
Conclusion: The high sensitivity and specificity of multislice computed tomography colonography in the diagnosis of colon pathologies will make it the screening modality and a serious alternative and complementary method for video colonoscopy in the evaluation of colon pathologies.
