However, we are not assured if it is meaningful for them to receive CRC screening, especially colonoscopy as a second-stage examination considering
their remaining life expectancy. The purpose of this study was to evaluate Wnt inhibitor the efficacy of colonoscopy for advanced aged people performed as a detailed examination for CRC screening as compared with people of non-advanced age. Methods: A total of 804 persons (403 men and 401 women, mean age 70.3 years), who underwent the entire colonoscopy because of positive FOBT between 2008 and 2013, were divided into two groups: group A aged 80 or older–176 persons, and group B aged under 80–628 persons. The detection rates of total CRC, invasive CRC, and premalignant lesion (adenoma) were determined and compared between the two groups. Results: CRC was detected in 18 persons (10.2%) in group A and in 43 (6.8%) in group B (p = 0.147). The detection rate of invasive CRC,
the depth of which is deeper than the mucosal layer, was significantly higher in group A (14 persons, 8.0%) than in group B (18, 2.9%), (p = 0.013). The detection rates of adenoma showed no significant difference between the two groups. Conclusion: Invasive CRC showed a higher detection rate in advanced aged people than in those aged under 80. We conclude that it will be meaningful for advanced aged Opaganib ic50 people to receive detailed 上海皓元医药股份有限公司 colonoscopy because of the high detection rate of invasive CRC which will soon become life-threatening and shorten
their limited expected life span even further. Key Word(s): 1.

A new method for endoscopic placement of the capsule is described. Methods: A transparent hood (MH–464, Olympus, Japan), with the inside wall lined with vinyl tape, is attached to the tip of the endoscope.
