This exam allows us to see inside the anal canal. Finding and treating abnormal cells at the earliest stage increases the chance of control and cure.
Before the Exam
Please call our clinic if you are taking aspirin, ibuprofen, vitamin E or herbal medicine. These can cause more bleeding. You may need to stop this medicine before the exam.
24 hour hours before the exam you must NOT use douches, enemas, creams or have anal receptive sex. This can affect test results.
Expect the visit to take 40-60 minutes. Following the exam, take the rest of the day off from heavy work and activities.
You will lie down on your left side with knees bent. You will have a brief rectal exam with a gloved finger and a numbing lubricant. The small tube-like scope will gently slide into the anal canal. The microscope looks for abnormal cells. Small cell samples may be taken. You may feel some pain or tugging as the sample is taken, this lasts less than one minute. If you have bleeding, it is quickly stopped with silver nitrate or pressure.
After the Exam
If biopsies (cell samples) are taken, expect a small amount of bleeding for 1-2 days. You may see more bleeding after bowel movements. This may last for 4 days. This is normal.
Do not put anything into your anus until rectal bleeding has stopped.
You may have mild pain for a few hours to a few days.
• You may shower. No tub baths or swimming.
• Wear loose fitting clothes.
• Avoid sitting or standing for more than an hour at a time for the first 1-2
