Proctoscopy is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope, although the latter may be a bit longer) is used to examine the
fibre-optic
proctoscopes allow more extensive observation with less discomfort.
Proctoscopes
anoscope
and a rectoscope
A proctoscope is a hollow, tube-like
speculum that is used for visual inspection of the rectum.[2][3] Both disposable and non-disposable proctoscopes are available for use. Out of these, the non-disposable Kelly's rectal speculum,[4] named after the American gynecologist Howard Atwood Kelly, is the most commonly used speculum for proctoscopy. Some proctoscopes have a light source for better visibility. The proctoscope is inserted into the anal canal with the patient in Sims' position
. Fibre optic proctoscopes are now available which cause less discomfort to the patient.The proctoscope is used in the diagnosis of
rectal polyp. It is used therapeutically for polypectomy
and rectal biopsy.
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
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.
