Overview 

What is a Sigmoidoscopy?

A Sigmoidoscopy is a test, which allows the Endoscopist to look directly at the left side of your large bowel (colon). In order to do this, a flexible tube the thickness of a finger, is carefully passed through the anus into the rectum and into the large bowel. This can be uncomfortable as bends in the colon are negotiated and air is used to inflate the colon. The Sigmoidoscope has a small camera attached which is connected to a monitor system where images can be seen. In order for this test to be successful it is important that we give you an enema on arrival. This will assist in cleaning your bowel and enable us to make a correct diagnosis.
