This is a procedure to examine your large bowel using a long, thin flexible fibreoptic tube attached to a camera and light. It is inserted through the anus (back passage) and into the large intestines.
There are two types of examination, a flexible sigmoidoscopy which looks at the back passage and some of the large bowel and, a colonoscopy which looks at the entire large bowel.
You can request for a sedation to help you relax during the test.
The test will allow your surgeon to have a good examination of your large bowel and perform procedures like biopsies and removing polyps.
