Mr Siraj Rajaratnam - General & Colorectal Surgeon
A long, narrow tube with a tiny camera attached (sigmoidoscope) is inserted into your anus and moved through your lower large intestine (bowel). This allows the surgeon a view of the lining of the lower large intestine (sigmoid colon). If necessary, a biopsy (small piece of tissue) may be taken for examination in the laboratory.
