About Anoscopy

An anoscopy is a diagnostic procedure that allows our surgeons at Houston Colon and Rectal Surgery to observe any abnormalities within the anus and rectum or the anorectal area. This is accomplished by inserting an anoscope into the anus to view the lining of the rectum and the delicate skin surrounding the anal opening. An anoscopy can be administered to detect a range of issues that affect the rectal or anal areas, such as anal fissures, abscesses, hemorrhoids, polyps, and anal or rectal cancer. While some patients report feeling a slight pressure during the diagnostic, very few feel any pain. Our skilled specialists are very thorough and take every necessary precaution to effectively identify the cause for your colorectal issues. Contact one of our North Houston or West Houston, TX offices to receive the high level of care that you can only receive when you visit our team of board-certified surgeons.

Before the Exam

Before we perform your anoscopy, you will need to empty your bowels, which will make you more comfortable during the procedure. This may involve giving yourself a Fleet® enema prior to the test or taking a laxative. These types of enemas can be found easily at your local drugstore or supermarket. Our surgeon will give you detailed information about how to prepare for your anoscopy before your appointment. Typically, patients do not have to cease taking any medications for this diagnostic. Our team will provide you with specific instructions, depending on the prescription drugs you're currently taking.

During the Exam

Your anoscopy will be performed at one of our North Houston or West Houston, TX offices. First, you will be asked to either lie on your side with your knees pulled up to your chest or bend forward over the examination table. The anoscope is a stainless steel or disposable device that is about 3 – 5 inches long and two inches wide, which is roughly the width of an average stool. After applying lubricant, the anoscope will be gently and steadily inserted into your anus. You may be asked to "push" to stimulate the muscle function of a bowel movement, and then you will be asked to relax. This action will allow our surgeon to position the device with ease and identify any abnormalities, such as bulges along the rectum. A light will be shined into the tube, giving our team a better view of the lining of your rectum and anus. Once the diagnostic is complete, the anoscope is slowly removed. We will be able to inform you of your results immediately following your anoscopy.

Additional Testing

Our surgeons sometimes perform other diagnostics alongside your anoscopy, such as a DRE (digital rectal exam) or a biopsy if any polyps or cancer is found. Depending on the results of your diagnostic, you may require additional testing following your anoscopy. If cancer is detected, you may be asked to undergo a series of tests, including CT scans, x-rays, blood tests, biopsies, or others. If more diagnostics are needed, this information will be made known to you so you can prepare accordingly.

When you arrive at one of our North Houston or West Houston, TX offices experiencing symptoms like pain, rectal bleeding, or constipation, our team goes above and beyond to determine the underlying cause of your condition and treat your condition accordingly.
