| [ Summary ] |
Full-spectrum endoscopy (FUSE) is the nextgeneration endoscopic system in which a CCD lens is put on in both sides of the scope tip. It is hoped detection of lesions during colonoscopy will be improved by using FUSE. From the results of prospective controlled trials carried out in western countries, it has been reported that adenoma miss rates (AMR) with FUSE were significantly lower in comparison to those with conventional standard forward viewing colonoscopy. However, some contradictions occur in the usefulness of the FUSE in relation to our ability to detect lesions because it has been reported that there was not a significantly different adenoma detection rate (ADR) observed in a subsequent study. We commented primarily on the results reported and summaries of multicenter randomized controlled trials (J-FUSE STUDY) conducted in Japan. |
