Sigmoidoscopy

A long, narrow tube with a light attached (sigmoidoscope) is inserted into your anus and moved through your rectum (bowel). This allows the surgeon a view of the lining of the lower large intestine. If necessary, a biopsy (small piece of tissue) may be taken for examination in the laboratory.
