A colorectal polyp (or colon polyp) is a fleshy growth (polyp) occurring on the lining of the colon or rectum.[1] Untreated colorectal polyps can develop into colorectal cancer.[1]
Symptoms
Colorectal polyps are not usually associated with symptoms.[1] When they occur, symptoms include rectal bleeding, bloody stools, abdominal pain and fatigue.[1] A change in bowel habits may occur including constipation and diarrhoea.[1] Occasionally, if a polyp is big enough to cause a bowel obstruction, there may be nausea, vomiting and severe constipation.[1]
Screening and diagnosis
Colorectal polyps can be detected using a faecal occult blood test, flexible sigmoidoscopy, colonoscopy, virtual colonoscopy, digital rectal examination, barium enema or a pill camera.[1]
Treatment
Polyps can be removed during a colonoscopy or sigmoidoscopy using a wire loop that cuts the stalk of the polyp and cauterises it to prevent bleeding.[1]
Structure
Polyps are either pedunculated (attached to the intestinal wall by a stalk) or sessile (grow directly from the wall).[1]
