| Outline of Final Research Achievements |
We conducted a multicenter study to clarify the accuracy of colon capsule endoscopy as new diagnostic modality for the diagnosis of colorectal tumors (in particular, flat or depressed lesions). In this study, colon capsule endoscopy was shown to have 94% sensitivity (62/66). The relative sensitivity of colon capsule endoscopy compared to traditional total colonoscopy was 1.43 (165/115) in protruded lesion and 1.58 (82/52) in flat or depressed lesion. Then, we investigated the detection rate of colorectal lesions using dual camera devices equipped by colon capsule endoscopy in comparison with theological single camera devices. The dual camera increased the detection rate for flat or depressed lesion by a factor of 1.6-1.8 times higher when compared to a theological single camera. Our study revealed that colon capsule endoscopy has enough sensitivity for use in patients suspected of having flat or depressed lesions.
