A colonoscopy is an examination of the colon using a soft, flexible fiber-optic instrument through which biopsies and polyp removal can also be performed.

How a Colonoscopy is Performed

You lie on your left side with your knees drawn up toward the abdomen. After administration of an intravenous sedative and analgesic, the colonoscopy instrument is inserted through the anus and gently advanced under direct vision to the terminal small bowel.

During the colonoscopy, air will be inserted through the scope to provide a better view. Suction may be used to remove secretions.

Since better views are obtained during withdrawal than during insertion in a colonoscopy procedure, a more careful examination is done during withdrawal of the scope. Tissue samples may be taken with tiny biopsy forceps inserted through the scope. Polyps can be removed with electrocautery snares, and photographs can be taken.
