Proctoscopy is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope) is used to examine the anal cavity, rectum or sigmoid colon. A proctoscope is a short (10in or 25 cm long), straight, rigid, hollow metal tube, and usually has a small light bulb mounted at the end. During proctoscopy, the proctoscope is lubricated and inserted into the rectum, and then the obturator is removed, allowing an unubstructed view of the interior of the rectal cavity. This procedure is normally done to inspect for hemorrhoids or rectal polyps and might be mildly uncomfortable as the proctoscope is inserted further into the rectum. Modern fibre-optic proctoscopes allow more extensive observation with less discomfort.

Additional recommended knowledge

Disposable proctoscopes without light are also available. The proctoscope also has a hollow channel through which other instruments may be inserted. For example, another instrument may be used to take a biopsy of a small amount of tissue for examination under a microscope. Also, air may be injected through the proctoscope to help make viewing easier. Similar instruments, the sigmoidoscope and colonoscope may be used to visualize more proximal parts of the bowels.
