What kind of doctor provides Capsule Endoscopy?
Capsule endoscopy is ordered and reviewed by a gastroenterologist, a doctor who specializes in the digestive tract. It takes pictures of the inside of your digestive tract. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Capsule endoscopy takes pictures of the inside of your digestive tract. You swallow a capsule about the size of a large vitamin pill. Inside are one or two tiny cameras, a light, a battery, and a radio transmitter. As it travels the same path as food, it takes pictures. It can see parts of the small intestine that a colonoscopy or stomach scope cannot reach.
Why a doctor might recommend it
Doctors use it to find the cause of bleeding in the digestive tract. It can also spot ulcers, polyps, tumors, Crohn disease, and celiac disease. It is often used when a colonoscopy or an upper endoscopy did not find the source of bleeding.
How to prepare
Follow your doctor's instructions closely. Your doctor may ask you to take medicine to clear your bowels and to have only clear liquids before the test. You may also be asked not to eat or drink before it. Follow your doctor's instructions about exactly when to stop eating and drinking. Be sure to tell your doctor about all the medicines you take, because you may be asked to not take some medicines during this test, since they could interfere with the camera. Also tell them if you have had bowel blockages, trouble swallowing, a pacemaker, or past abdominal surgery. Wear loose, two-piece clothing on the day of the test.
What happens during it
You swallow the capsule while sitting up. It has a slippery coating that makes it easier to swallow. A recorder is placed on your waist or shoulder to collect the pictures. Then you go about most of your normal activities. Do not lift heavy things or exercise hard. Do not have an MRI while the capsule is inside you. The capsule passes out in a bowel movement and can be flushed down the toilet.
Recovery
Your provider will tell you when you can eat and drink again. The capsule leaves the body within 24 hours most of the time. If you do not see it within 2 weeks, tell your provider. It may take up to a week to learn your results.
Risks and side effects
There are very few problems that can occur with capsule endoscopy. If your intestines are blocked or narrow, the capsule can get stuck. If this happens, you may need to have it removed with a scope or with surgery, although this is rare. Do not have an MRI or go near a powerful magnetic field while the capsule is inside you, because you could have serious damage to the digestive tract and abdomen. Call 911 if you have chest pain after swallowing the capsule. Call your provider right away if, after swallowing the capsule, you have a fever, trouble swallowing, vomiting, cramping, or abdominal pain. The capsule only takes pictures. It cannot take a tissue sample or treat a problem.
Who performs it
A technician downloads the images from the recorder to a computer. A health care provider reviews the pictures to look for problems.
Common questions
Will I feel the capsule?
Most people find the test comfortable. The capsule is small and coated, so it is usually easy to swallow.
What happens to the capsule?
It passes out of your body in a bowel movement, usually within 24 hours. You can flush it down the toilet without harming the plumbing.
Can capsule endoscopy treat a problem?
No. It only takes pictures. If it finds something, your doctor may need another test, like a scope, to treat it.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. They do not perform the test themselves.
