What is Capsule Endoscopy?

Capsule Endoscopy allow for the examination the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum, ileum). You will get a pill sized video camera for you to swallow. This camera has its own light source and takes pictures of your small intestine as it passes through. These pictures are sent to a small recording device you have to wear on your body.

I will be able to view these pictures at a later time and might be able to provide you with useful information regarding your small intestine.

 

Why is Capsule Endoscopy Done?

Capsule endoscopy helps me 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 most new diagnostic procedures, not all insurance companies are currently reimbursing for this procedure. We may need to obtain a prior autherization from the insurance plan before performing the test.

How Should You Prepare for the Procedure?

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. You will be provided with complete preperation instructions. Please Tell me 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. Also, it’s good to know about the presence of a pacemaker or defibrillator, previous abdominal surgery, or previous history of bowel obstructions in the bowel, inflammatory bowel disease, or adhesions.

A bowel prep/cleansing  maybe needed prior to the examination.

What Can I Expect During Capsule Endoscopy?

Before the exam we will applying a sensor device to your abdomen with adhesive sleeves (similar to tape). The pill-sized 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.

What Happens After Capsule Endoscopy?

You will be able to drink clear liquids after two hours and eat a light meal after four hours following the capsule ingestion. You will have to avoid vigorous physical activity such as running or jumping during the study. Your will receive your test results within the week following the procedure; however, the results of some tests might take longer.

What are the Possible Complications of Capsule Endoscopy?

Although complications can occur, they are rare when doctors who are specially trained and experienced in this procedure perform the test. There is potential for the capsule to be stuck at a narrowed spot in the digestive tract resulting in bowel obsctruction. This usually relates to a stricture (narrowing) of the digestive tract from inflammation, prior surgery, or tumor. It’s important to recognize obstruction early. Signs of obstruction include unusual bloating, abdominal pain, nausea or vomiting. You should call immediately for any such concerns. Also, call  if you develop a fever after the test, have trouble swallowing or experience chest pain. Be careful not to prematurely disconnect the system as this may result in loss of pictures being sent to your recording device.
