Colectomy consists of the surgical resection of any extent of the large intestine (colon). It is also an occasional term used to describe removing the entire large intestine along with the rectum, but the appropriate term is proctocolectomy, where the whole large intestine and rectum are removed. ==Indications== Some of the most common indications for colectomy are: * Colon cancer * Diverticulitis and diverticular disease of the large intestine * Trauma * Inflammatory bowel disease such as ulcerative colitis or Crohn's disease. Colectomy neither cures nor eliminates Crohn's disease, instead only removing part of the entire diseased large intestine. A colectomy is considered a cure for ulcerative colitis because the disease attacks only the large intestine and therefore will not be able to flare up again if the entire large intestine (cecum, ascending colon, transverse colon, descending colon and sigmoid colon) and rectum are removed. However, it does not always take away extra-intestinal symptoms. * Prophylactic colectomy can be indicated in some forms of polyposis, Lynch syndrome and certain cases of inflammatory bowel disease because of high risk for development of colorectal cancer. * Bowel infarction * Typhlitis 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「colectomy」の詳細全文を読む スポンサード リンク
