High-resolution anoscopy is an examination of the anal canal. It is performed with the aim to help diagnose anal conditions and mainly to look for abnormal cells in the anus that have a high chance of turning into cancer.
The procedure takes around 10 minutes to complete and is performed on an outpatient basis at OneWelbeck.
High-resolution anoscopy may be recommended if you are experiencing symptoms such as:
The procedure can help identify abnormal cells in the lining of the anus and rectum, so it is especially helpful in screening for and diagnosing suspicious anal lesions and also for monitoring for the return of anal cancer after treatment.
Usually this is recommended after a positive HPV test, especially when this shows that the patient could be at higher risk for anal dysplasia or anal cancer.
To have a high-resolution anoscopy you will be lying on your side with your knees bent and pulled up toward your chest.
This diagnostic test uses a small diameter plastic tube, slightly wider than a finger, and this is inserted gently in the anus after being lubricated. Differently from a standard anoscope, this is connected to a screen and the view is magnified many times, so the doctor can see better images, reducing chances to miss small abnormalities that usually are hard to see with a naked eye.
Sometimes biopsies are necessary to make a final diagnosis. This may involve taking small samples of tissue. Usually the procedure is pain free and could cause only minimal controlled bleeding.
There is no preparation needed for a high-resolution anoscopy. However, it is advised to avoid enemas or anything to clear out the anal canal as this may wash away cells that need to be collected for testing. You should also avoid placing anything in your anal canal for 24 hours prior to the procedure.
The procedure is not painful but you may feel some discomfort and pressure. You may experience some soreness afterwards and there may be some mild bleeding if a biopsy was taken, but these should go away after a few days.
The test does not require anaesthetic or sedation so it’s safe for you to drive yourself home and go about your normal activities straight after the procedure.

Shifting levels of hormones during the transition into menopause cause changes in a woman’s body which can affect the vagina, vulva and bowels. Studies have shown that approximately 50% of post-menopausal women experience vaginal dryness - yet only 25% seek treatment and women with incontinence issues will wait for 6 years before they seek help.
Consultant gynaecologist and obstetrician Elaine Palmer and consultant colorectal surgeon Sarah Mills. discuss these issues, including when to seek help with bowel issues.
