What is a Sigmoidoscopy?
Sigmoidoscopy is a procedure in which a doctor looks in your large intestine. A length of flexible tube connected to a fiberoptic camera is used. A light is transmitted through the scope to the tip by a bundle of light fibers. The doctor uses this light to look at your intestine through an eyepiece or video screen.
