| [ Summary ] | CT colonography (CTC) became covered under Japanese national health insurance in January 2012. Since then, CTC has been performed at many facilities and is becoming widely used as a standard component of colon examination. CTC was introduced to our hospital in May 2003, and has been performed on 28,950 patients to date (as of September 2018). Sensitivity, ≧10 mm and 92.5 %, ≧ 6 mm and 88.1 %, good results are obtained. Only one case of suspected rectal perforation (0.0035 %) is the incident. We believe that 1) performing CTC, a highly approachable procedure, prior to CS, increases the rate of patients undergoing colorectal examination; 2) patients are more likely to understand the necessity of CS if they are shown the images from CTC; and 3) by performing CTC, endoscopists can concentrate on examining and treating CS efficiently. The assignment of CTC as a test to be performed between a fecal occult blood test and CS and the detection of colorectal cancer with occult blood, diagnosis with CTC, and treatment with CS can lead to early detection and early treatment. | |
