Capsule Endoscopy Prep

Capsule Endoscopy lets your doctor examine the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum, ileum). Your doctor will use a pill-sized video capsule called an endoscope, which has its own lens and light source and will view the images on a video monitor. You might hear your doctor or other medical staff refer to capsule endoscopy as small bowel endoscopy, capsule enteroscopy, or wireless endoscopy.

Capsule endoscopy helps your doctor evaluate the small intestine. This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn’s disease), ulcers, and tumors of the small intestine.

As is the case with some diagnostic procedures, not all insurance companies are currently reimbursing for this procedure. You may need to check with your own insurance company to ensure that this is a covered benefit.

An empty stomach allows for the best and safest examination, so you should have nothing to eat or drink, including water, for approximately twelve hours before the examination. Your doctor will tell you when to start fasting.

Tell your doctor in advance about any medications you take including iron, aspirin, bismuth subsalicylate products, and other over-the-counter medications. You might need to adjust your usual dose prior to the examination. Discuss any allergies to medications as well as medical conditions, such as swallowing disorders and heart or lung disease. Tell your doctor of the presence of a pacemaker, previous abdominal surgery, or previous history of obstructions in the bowel, inflammatory bowel disease, or adhesions.

Your doctor will prepare you for the examination by applying a sensor device to your abdomen with adhesive sleeves (similar to tape), or a sensor belt. The capsule endoscope is swallowed and passes naturally through your digestive tract while transmitting video images to a data recorder worn on your belt for approximately eight hours. At the end of the procedure, you will return to the office and the data recorder is removed so that images of your small bowel can be put on a computer screen for physician review.

Most patients consider the test comfortable. The capsule endoscope is about the size of a large pill. After ingesting the capsule and until it is excreted, you should not be near an MRI device or schedule an MRI examination.

Your doctor generally can tell you the test results within the week following the procedure; however, the results of some tests might take longer.

Although complications can occur, they are rare when doctors who are specially trained and experienced in this procedure perform the test. Potential risks include complications from obstruction. This usually relates to a stricture (narrowing) of the intestine from inflammation, prior surgery, or tumor. It’s important to recognize early signs of possible complications. If you have evidence of obstruction, such as unusual bloating, pain, and/or vomiting, call your doctor immediately. Also, if you develop a fever after the test, have trouble swallowing, or experience increasing chest pain, tell your doctor immediately. Be careful not to prematurely disconnect the system as this may result in loss of image acquisition.
