Many patients wonder during a proctology visit whether anoscopy is really necessary. A common question is: “Isn’t a digital rectal examination enough?” The answer is: not always. A digital rectal examination is very important, but it does not allow the doctor to see the inside of the anal canal.
This article explains the difference between a digital rectal examination and anoscopy, why both examinations may complement each other and when anoscopy is particularly important. If you have rectal bleeding, pain, a lump, itching, burning, discharge or recurrent symptoms, book a proctology consultation in Gdańsk.

Digital rectal examination — what does it show?
A digital rectal examination, also called a rectal examination by finger, is one of the basic elements of a proctology consultation. The doctor performs it with a gloved finger and gel, after explaining to the patient what the examination involves.
A digital rectal examination allows the doctor to assess, among other things:
- tenderness around the anus and anal canal,
- sphincter tone,
- the presence of some lumps, thickening or larger lesions,
- tenderness, resistance or asymmetry,
- the final part of the rectum in an approximate way,
- in men — in selected situations, also the prostate.
This examination is important and often necessary, but it has limitations. The doctor may feel certain abnormalities, but cannot inspect them directly. In proctology, the appearance of a lesion, its location, colour, bleeding, ulceration, mucosal condition and relation to the anal canal are diagnostically important.
The key difference: with a finger you can feel, with an anoscope you can see
Simply put: during a digital rectal examination, the doctor assesses by touch, while during anoscopy — by sight. These are two different sources of information.
A finger examination may suggest that something is abnormal, but it does not always allow the doctor to determine exactly what the lesion is. Anoscopy makes it possible to directly inspect the anal canal and the final part of the rectum using a short speculum.
That is why the phrase “we do not have a camera in a finger” captures the problem well, although in medical communication we say it more calmly: a digital rectal examination does not provide an image of the mucosa. The doctor may feel something, but cannot see whether it is a haemorrhoid, fissure, inflammation, mucosal lesion, polyp, condyloma, ulceration or a lesion requiring further diagnostics.
“A digital rectal examination is very important, but it does not replace anoscopy. By touch we can assess a lot, while anoscopy allows us to see the anal canal and better understand where symptoms come from.”
— Dr Kamil Smok, surgeon and proctologist
Why may anoscopy be necessary?
Anoscopy may be needed when the doctor wants to inspect the anal canal and the final part of the rectum more precisely. It is particularly helpful when the patient reports bleeding, pain, itching, burning, a feeling of a lump, discharge or recurrent symptoms despite treatment.
Anoscopy allows the doctor to:
- inspect the mucosa of the anal canal,
- assess internal haemorrhoids,
- see an anal fissure or signs of inflammation,
- identify a possible source of bleeding,
- assess mucocutaneous lesions,
- check whether a palpable lesion requires further diagnostics,
- decide whether proctological treatment is sufficient or additional tests are needed.
You can read more about the examination itself here: anoscopy — anal examination.
Does anoscopy provide “100% certainty”?
It should not be said that anoscopy provides 100% certainty or that it always rules out all serious diseases. That would be an oversimplification. Anoscopy is very useful, but it primarily assesses the anal canal and the final part of the rectum. It does not examine the entire colon.
In practice, this means that anoscopy may help diagnose many causes of symptoms around the anus, but in some patients further diagnostics may be needed, such as rectoscopy, colonoscopy, laboratory tests, imaging or biopsy.
The safest way to say it is this: anoscopy increases the accuracy of proctological diagnostics because it allows the doctor to see what cannot be assessed by a finger examination alone.
Digital rectal examination vs anoscopy — comparison
| Element of examination | Digital rectal examination | Anoscopy |
|---|---|---|
| Method of assessment | touch | direct inspection of the anal canal |
| What can it assess? | sphincter tone, tenderness, larger lumps, thickening | mucosa, internal haemorrhoids, fissure, inflammation, source of bleeding |
| Does it show the appearance of a lesion? | no | yes, within the anal canal and final part of the rectum |
| Is it enough in bleeding? | not always | often helps identify the source of bleeding in the anal canal |
| Does it replace colonoscopy? | no | no, if symptoms suggest a problem higher in the bowel |
The risk of missing a more serious disease
Not every lump, bleeding or pain near the anus means a serious disease. Most often, the cause is haemorrhoids, an anal fissure, perianal thrombosis, inflammation or irritation. The problem is that some symptoms may overlap.
Without directly inspecting the anal canal, there is a greater risk of:
- too quickly assuming that symptoms are “just haemorrhoids”,
- missing an anal fissure, inflammation or another cause of pain,
- not noticing a mucosal lesion, condyloma, polyp or ulceration,
- delaying the decision to perform further diagnostics,
- treating symptoms rather than their actual cause.
That is why, when a doctor suggests anoscopy, it usually results from the need for a more precise assessment, not from an “unnecessary” examination.
When is anoscopy particularly important?
Anoscopy is particularly important when symptoms may originate from the anal canal, but their cause cannot be reliably established based only on conversation and external examination.
The examination is especially worth considering with symptoms such as:
- rectal bleeding,
- blood on toilet paper,
- anal pain, especially during bowel movements,
- a feeling of a lump or foreign body,
- itching and burning around the anus,
- discharge, moisture or irritation,
- recurrent symptoms despite treatment,
- suspected internal haemorrhoids,
- suspected anal fissure,
- uncertainty whether the lesion is benign.

Should you be afraid of anoscopy?
Usually, no. Anoscopy is a short examination and is usually well tolerated. It may cause a feeling of pressure, fullness or discomfort, but in most patients it is not very painful.
Sensations depend on the situation. If the patient has an acute fissure, thrombosis, abscess or severe inflammation, the examination may be less comfortable. In such cases, the doctor adjusts the scope of the examination to the patient’s symptoms and tolerance.
Before the examination, it is worth telling the doctor about pain, previous bad experiences or stress. The proctologist can then calmly explain each stage and perform the examination as gently as possible.
Can you refuse anoscopy?
A patient has the right to refuse any examination. It is worth knowing, however, what such a decision means diagnostically. If the doctor recommends anoscopy and the patient declines it, the assessment of the anal canal may be incomplete.
Refusing the examination may make it more difficult to:
- identify the source of bleeding,
- confirm internal haemorrhoids,
- diagnose a fissure or inflammation,
- assess a lesion felt during a finger examination,
- decide whether further diagnostics are needed.
The best solution is to talk with the doctor. If the patient is afraid of pain, feels embarrassed or does not understand the purpose of the examination, it is worth saying so. Calmly explaining the course of anoscopy often reduces anxiety.
Anoscopy and “haemorrhoid treatment without examination”
Many patients use ointments, suppositories or over-the-counter preparations for a long time, assuming that every symptom around the anus is haemorrhoids. This is understandable, but not always safe.
Bleeding, pain, itching, burning and a lump may result from different causes. If “haemorrhoid treatment” does not help, symptoms recur or bleeding appears, diagnostics should be performed instead of trying another preparation.
If haemorrhoids are actually diagnosed, more information is available here: haemorrhoid treatment in Gdańsk. However, this article does not replace the haemorrhoid treatment page — it explains why proper diagnostics are the first step.
“A patient does not have to like this examination, but should understand why we perform it. Anoscopy is not a punishment or a formality — it is a way to see the place from which symptoms may originate.”
— Sara Godyńska, MD, proctologist
When should you not postpone consultation?
It is worth seeing a proctologist when symptoms are new, recurrent or worrying. Consultation should especially not be delayed when bleeding, a lump or pain appears.
Book a visit if:
- you see blood on toilet paper, stool or in the toilet bowl,
- bleeding recurs,
- you feel a lump near the anus,
- pain is increasing or makes sitting difficult,
- itching, burning or discharge occurs,
- symptoms do not improve after treatment,
- you have a feeling of incomplete bowel movement,
- you are worried whether it is haemorrhoids, fissure, thrombosis or something more serious.
More urgent assessment is needed in case of heavy bleeding, black stool, fever, purulent discharge, a rapidly growing lump, ulceration, unintentional weight loss, anaemia or rapid deterioration of general condition.

Frequently asked questions
Is a digital rectal examination enough instead of anoscopy?
Not always. A digital rectal examination allows the doctor to assess tone, tenderness and some lesions by touch, but it does not allow direct inspection of the inside of the anal canal. Anoscopy gives the doctor the ability to view this area directly.
Why does the doctor recommend anoscopy?
The doctor may recommend anoscopy when they want to assess more precisely the source of bleeding, pain, itching, discharge, a feeling of a lump or suspected internal haemorrhoids, fissure or another lesion in the anal canal.
Does anoscopy give certainty of diagnosis?
Anoscopy increases diagnostic accuracy, but it does not automatically provide 100% certainty in every situation. If symptoms suggest a problem higher in the bowel or a lesion requiring verification, the doctor may recommend further tests.
Does anoscopy hurt?
It is usually well tolerated and takes a short time. It may cause pressure or discomfort. If the patient has severe pain, a fissure, thrombosis or inflammation, the doctor adjusts the scope of the examination to the situation.
Can I refuse anoscopy?
Yes, the patient may refuse the examination. However, it is worth discussing with the doctor what this means for diagnostics. Declining anoscopy may limit the ability to accurately assess the anal canal.
Does anoscopy replace colonoscopy?
No. Anoscopy assesses the anal canal and the final part of the rectum. It does not examine the entire colon. If symptoms suggest a source of bleeding higher in the bowel, colonoscopy or other tests may be needed.
Which proctologist should I see in Gdańsk?
At Wyspa Medycyny Przyjaznej, consultations are provided by Sara Godyńska, MD, Justyna Szul, MD and Dr Kamil Smok. You can start with a proctology consultation in Gdańsk.
Has your doctor recommended anoscopy?
It is worth knowing why this examination is performed. Anoscopy allows the doctor to see the anal canal and better determine the cause of bleeding, pain, itching or a lump.
Book a proctology consultation →Summary
A digital rectal examination is an important element of a proctology consultation, but it is not always enough. It allows the doctor to assess the anal area by touch, but it does not allow direct inspection of the inside of the anal canal. That is why anoscopy is needed in many situations.
Anoscopy helps inspect the anal canal and final part of the rectum, assess the source of bleeding, internal haemorrhoids, fissure, inflammation or other lesions. However, it does not replace colonoscopy if symptoms suggest a problem higher in the colon.
If you have bleeding, pain, a lump, itching, burning or recurrent symptoms, book a proctology consultation in Gdańsk. The doctor will assess whether anoscopy is needed and what further management will be appropriate.
