Colonoscopy
大腸内視鏡 (daichō naishikyō)
Colonoscopy is a procedure in which a flexible camera is inserted through the rectum to examine the entire large intestine (colon). It is used to screen for and remove polyps before they become colorectal cancer, and to investigate bleeding, diarrhea, and unexplained abdominal pain. Japan's annual fecal occult blood test (便潜血検査, ben senketsukensa) screens for colon cancer and positive results lead to colonoscopy.
Bowel preparation (下剤服用, gezai fukuyō) requiring laxative consumption the evening before is necessary for colonoscopy in Japan; the procedure is often performed under light sedation.
