Anoscopy: Anoscopy is a procedure used to visualize the wall of the anus and lowest portion of the rectum. Anoscopy can be performed in the doctor's office without any special preparation to empty the colon. The anoscope is the instrument used to allow visualization of the wall of the anus and identification of abnormalities such as inflammation, tumors, trauma, or hemorrhoids in the anal canal. In most cases this procedure does not result in pain, but patients undergoing anoscopy may feel pressure similar to the pressure of a bowel movement.
