What is an Anoscope, And How to Use Anoscope?

What is An Anoscope?

Anoscope is a medical instrument used by doctors to examine the anus and rectum. It is a 3-4 inches long tube made of medical-grade plastic. Anoscope has a light source at the end that allows clear viewing of the rectal tissues. 

What is a Good Quality Anoscope?

A good quality anoscope will be latex-free to avoid allergies. It should have no ridges to allow smooth insertion in the anus. The equipment should have no mounds for an atraumatic experience. In single-use anoscopes, sterility is important. It should have a detachable torch for versatile usage.

Why Do Doctors Use An Anoscope?

The anorectal verge is an area that connects the rectum to the anal opening. The end of this verge is the anal sphincter. Its basic function is to keep the rectal canal closed and store stool before egestion. 

Due to the anal opening, this area is more prone to infections from bacteria, viruses, and parasites. Moreover, everyday sphincter movement and dietary changes result in straining anal muscles during diarrhea and constipation.

Doctors need to examine the anorectal tissues to diagnose and treat any abnormality which is causing discomfort to the patient. An anoscope gives them a direct view of the anorectal verge, and diseases are easy to diagnose.

How to Use An Anoscope?

Doctors perform a medical procedure called anoscopy using an anoscope. It is a harmless process that checks the anal and rectal tissues for the above-mentioned diseases. You can perform an anoscope the following way on a patient:

  2. Prescribe a laxative or enema for constipated patients.
  3. Ask the patient to lie down and relax.
  4. Put the patient in either a fetal or bending-over position. 
  5. Lubricate the anoscope with K-Y jelly or another lubricant.
  6. Insert the anoscope very carefully in the patient's anus.
