A proctoscopy is a short examination that lets a doctor or nurse look directly inside the anal canal and the very lowest part of the rectum, using a narrow, rigid, hollow tube called a proctoscope. It is one of the most common tests used to investigate bottom symptoms because it is quick, requires no sedation, and answers the question that a finger alone cannot: what does the lining of the canal actually look like. Most people who need one have been referred because of bleeding, a lump, discomfort, itching or a change in bowel habit, and a proctoscopy is very often the test that finally confirms or rules out internal haemorrhoids. If you have been told you need one and are nervous about what is involved, that reaction is completely normal — this is an intimate examination — but it is also one of the briefest and least complicated tests in medicine, usually over within a couple of minutes.
A proctoscopy is used to find the cause of symptoms that come from the anal canal rather than higher up in the bowel. The most common reasons for one are rectal bleeding, particularly bright red blood on the paper or in the pan; a lump, swelling or something that feels like it is coming down; persistent itching or soreness; mucus discharge; a feeling of incomplete emptying; or pain around the back passage. It is the standard way to diagnose and grade internal haemorrhoids, since these sit just above the point where ordinary vision and a finger examination stop being able to see clearly, and it can also identify anal fissures, polyps close to the anal margin, and other local causes of bleeding. It is not, on its own, a test for the rest of the colon — for that, a GP or specialist may also arrange a flexible sigmoidoscopy or colonoscopy, particularly if there are red-flag symptoms such as a change in bowel habit or unexplained weight loss. Our article on haemorrhoids or bowel cancer explains which symptoms warrant that broader investigation.
These three tests are often confused because they examine overlapping territory with similar-looking equipment. A proctoscopy (sometimes called rigid proctoscopy) uses a short, rigid tube, usually around 10 to 12 centimetres, to view the anal canal and the very bottom of the rectum. An anoscopy is closely related and sometimes used interchangeably in conversation — some instruments and services draw a line between the two, with anoscopy focused specifically on the anal canal and proctoscopy extending slightly further into the lower rectum, but in UK clinical practice the terms are frequently used for the same short rigid examination. A flexible sigmoidoscopy goes much further, using a soft, flexible, camera-tipped scope to examine the last 40 to 60 centimetres of the bowel, and a colonoscopy examines the entire large bowel. If your only symptoms point to the anal canal itself — bleeding, a lump, itching, soreness — a proctoscopy alone is often sufficient. If there is any suggestion of a problem higher up, a longer scope is the appropriate next step, and a proctoscopy does not replace that when it is needed.
This is the question almost everyone actually wants answered, and the honest answer is that a proctoscopy is usually uncomfortable rather than painful. The anal canal is sensitive, so there is an unmistakable feeling of pressure and fullness as the proctoscope is passed, and a brief urge that feels like needing the toilet, but the examination itself does not typically hurt in the way an injury would, and no anaesthetic is needed for most people. The lining of the lower rectum, above a point called the dentate line, has very little pain sensation, which is part of why the test tends to be tolerable even though it looks intimidating. People with an active anal fissure or a thrombosed external haemorrhoid are the exception — the skin at the anal margin is genuinely painful in those conditions, and a clinician will usually go gently, use extra lubricant, or in some cases delay the full examination until the acute pain has settled, rather than push through significant pain. Being asked to relax, breathing slowly and not tensing the muscle makes a real difference to comfort, and a good clinician will talk you through each step and stop if you ask them to.
Preparation for a proctoscopy is minimal, which is one of its advantages over more involved bowel investigations. There is usually no need to fast, take laxatives, or follow a special diet beforehand — a normal bowel motion on the day, or the day before, is generally all that is needed for a clear view, though a clinic may occasionally suggest a small enema if the rectum is not empty. Loose, easy-to-remove clothing makes the practical side simpler. It helps to empty your bladder beforehand and to avoid a large meal immediately before the appointment if you tend to feel anxious, since nervousness can make some people feel briefly light-headed. There is no need to arrange a driver or take time off afterwards, because nothing about the test affects your ability to concentrate, drive or return to normal activities straight away.
The appointment starts with a conversation about your symptoms and relevant history, followed by the physical examination itself. You will usually be asked to lie on your side with your knees drawn up towards your chest, which is the position that gives the clearest access and view. The clinician first looks at the outside of the area and often performs a gentle digital rectal examination, feeling with a lubricated, gloved finger for lumps, tenderness or muscle tone, before introducing the proctoscope. The proctoscope itself is well lubricated and inserted slowly with a rounded, blunt inner tip called an obturator in place to make entry as smooth as possible; once it is in position, the obturator is removed and the clinician looks directly through the tube, sometimes with a light attached, to examine the lining as the instrument is gently withdrawn. The whole examination, from insertion to removal, typically takes one to two minutes, and most people describe the anticipation as far worse than the reality. Our article on what happens at a haemorrhoid appointment covers the wider consultation this usually sits within.
The most frequent finding on proctoscopy is internal haemorrhoids, and the examination allows the clinician to grade them by how far they prolapse: grade 1 stay entirely inside the canal, grade 2 come down with straining but return on their own, grade 3 need to be pushed back manually, and grade 4 are permanently prolapsed. Our guide to haemorrhoid types goes through these grades in more detail. A proctoscopy can also identify an anal fissure, though a fissure sitting right at the anal margin is often visible without needing to insert the scope at all; small polyps within reach of the instrument; anal warts; and, less commonly, other causes of local bleeding or abnormal tissue that would prompt a referral for biopsy or further imaging. What a proctoscopy cannot do is examine the bowel beyond its short reach, so a completely normal proctoscopy in someone with ongoing bleeding, a change in bowel habit, or other red-flag symptoms does not rule out a problem further up, and should prompt further investigation rather than reassurance alone.
Because a proctoscopy is a direct visual examination rather than a test that needs laboratory processing, in most cases the clinician can tell you what they saw immediately, in the same appointment. If haemorrhoids are found, they will usually describe the grade and discuss the range of treatment options in the same visit. If a biopsy is taken because something looks atypical, that sample is sent to a laboratory and results generally take one to two weeks, with the clinic arranging a follow-up conversation to go through them. If something is found that needs a longer scope or a specialist opinion, the clinician will explain why and arrange the appropriate referral rather than leaving you to interpret an inconclusive finding on your own.
Yes — a proctoscopy is a routine NHS examination, typically performed by a GP with the right equipment, or more commonly by a colorectal surgeon, general surgeon or specialist nurse in a hospital outpatient clinic after a GP referral. NHS waiting times for a first outpatient appointment vary widely by area and by how urgently the referral is marked, and can range from a few weeks to several months for a routine, non-urgent referral. A private consultation with examination generally means being seen and, where appropriate, having a proctoscopy performed within days rather than weeks, which is one of the main reasons people choose to pay privately for this specific step even when they intend to have any subsequent treatment on the NHS. Our article on NHS vs private haemorrhoid treatment sets out that comparison, including waiting times, in more detail.
A proctoscopy is not just a diagnostic step — for internal haemorrhoids, it is usually also the moment treatment becomes possible, because most non-surgical haemorrhoid treatments are delivered through the same instrument used to make the diagnosis. At our Glasgow and London clinics, once internal haemorrhoids are confirmed and graded by proctoscopy, we treat them the same way, in the same visit if you choose the combined consultation-and-treatment appointment: with eXroid electrotherapy, a low-dose direct current applied to the base of the haemorrhoid through the proctoscope, above the dentate line where sensation is minimal, which seals the feeding blood vessel so the haemorrhoid shrinks over the following weeks. There is no cutting and no general anaesthetic. Of 116 patients treated at our clinics since January 2025, 84% needed only one session. A consultation with examination is £365, consultation and treatment together on the same visit is £1,095, and a follow-up treatment if one is needed is £795. Other proctoscope-delivered options include haemorrhoid banding and sclerotherapy injections, and our guide to non-surgical haemorrhoid treatments compares all of the current approaches side by side.
A few concerns come up in almost every conversation about this test. Embarrassment is by far the most common one, and it is worth saying plainly that clinicians who perform this examination do so routinely, many times a week, and are focused entirely on finding out what is wrong rather than on anything else. Fear of pain is the second most common worry, and as covered above, the test is usually uncomfortable rather than painful, over quickly, and can be paused at any point if it is too much. Some people worry about needing their bowels open during the test — this is understandable but genuinely rare, and the instrument and technique are designed to minimise any such risk. Finally, people sometimes delay getting a proctoscopy out of fear that something serious will be found; in practice, the great majority of proctoscopies in people with typical bottom symptoms find nothing more serious than haemorrhoids, and finding out sooner rather than later, whatever the result, is almost always the better path.
If you have bleeding, a lump, itching, soreness or discomfort around your bottom that has not settled, a proctoscopy is very likely the test that will get you an answer, and it is a far less daunting procedure in reality than it sounds in advance. Our severity test takes a couple of minutes and can help you think through your symptoms before you see anyone, though it is not a diagnosis on its own. You can read about our procedure, book a consultation with examination at our Glasgow or London clinic, or contact us first if you have questions about what to expect. If a proctoscopy shows something we do not treat, we will tell you plainly and point you towards the right place.
