For the treatment of blood in stool, colonoscopy is the way to go. Majority of colonoscopies are conducted after oral laxatives administration in order to cleanse the blood clots. However, in emergency cases, your health care provider may opt for colonoscopy without doing any sort of cleansing. Another good thing about colonoscopy is that it can play a prominent part in stopping the bleeding, which is quite crucial. When colonoscopy cannot come up with the bleeding site, use of visceral angiograms is recommended. Surgery is the only option available when both colonoscopy and visceral angiogram does not prove effective.
