What it shows
A direct view of anal canal and lower rectal surfaces
An anoscope is a short, illuminated instrument viewing lining not always visible externally.
Its value is relating findings to the bleeding, pain, itching, discharge or lump prompting consultation.
When it adds information
When symptoms need examination from inside, not just outside
Assessment determines whether local examination answers the question or broader testing is needed.
Pain or burning
Examination relates symptoms to directly visible fissures, inflammation or other findings.
Itching, discharge or irritation
It may show lining changes and complement external examination for persistent symptoms.
A lump or suspected internal hemorrhoids
It shows internal anal canal tissue not always visible externally.
Tests answering different questions
Surface, tissue and bowel require different examinations
Choosing by name alone can miss the clinical question. Each test provides a different view.
Anoscopy
Directly views the anus, anal canal and lower rectal lining.
Endoanal ultrasound
Shows sphincters and surrounding structures when deeper anatomy affects decisions.
Explore endoanal ultrasoundSigmoidoscopy
Extends examination into the final large bowel when greater reach is needed.

A brief examination helps only if it answers the right question
The test complements examination and symptoms; it does not replace assessment or independently determine treatment.

Integrate findings into care
Information is related to symptoms to guide treatment, follow-up or another test.
Possible findings
Visible findings guide care for the area
Findings are interpreted alongside the concern; they may guide treatment or require further tests.
Internal hemorrhoids
Viewing the canal identifies internal hemorrhoidal tissue and its relation to bleeding or discomfort.
Fissures and irritation
It may reveal tears, redness or inflammation in the examined lining.
Lesions or growths
Visible changes may need documentation, follow-up or further assessment according to their features.
Discharge and internal openings
It can complement fistula assessment without replacing imaging needed to define the full tract.
Before the test
Confirm instructions before preparing yourself
Preparation varies with the reason, pain, medicines and additional interventions. The team provides the necessary instructions.
Examination scope
A local view does not exclude causes beyond the anal canal and lower rectum
If bleeding, history or findings require broader examination, the doctor may consider sigmoidoscopy, colonoscopy or other assessment.

Frequently asked questions
What to know before requesting anoscopy
What is anoscopy?
Direct examination of the anus, anal canal and lower rectum using a short illuminated anoscope.
Can it examine internal hemorrhoids?
Yes, along with other visible changes. Results are interpreted with symptoms and examination.
Is it the same as colonoscopy?
No. Anoscopy is limited to the anal canal and lower rectum; colonoscopy examines the whole large bowel.
Is it the same as endoanal ultrasound?
No. Anoscopy views the inner surface; ultrasound shows sphincters and surrounding tissues.
Is conventional anoscopy the same as high-resolution anoscopy?
No. High-resolution anoscopy uses magnification and an additional protocol to identify small tissue changes. This page describes conventional anoscopy.
Does it include a biopsy?
Do not assume one is included. Sampling is an additional intervention depending on the finding, purpose and arrangements confirmed by the team.
Do I need preparation?
Instructions vary. Confirm preparation with the team rather than using enemas or stopping medicines from general online guidance.
What do I need to send via WhatsApp?
Simply ask about times and availability for assessment. Clinical details are reviewed during care.
