What is Capsule Endoscopy?
Capsule Endoscopy lets your doctor examine the lining of the middle part of your child’s gastrointestinal tract. Your doctor will give you a pill sized video camera for your child to swallow. If your child can not swallow the capsule then it can sometimes be placed during an endoscopy. This camera has its own light source and takes pictures of your child’s small intestine as it passes through. These pictures are sent to a small recording device your child has to wear on their body.
Your doctor will be able to view these pictures at a later time and might be able to provide you with useful information regarding your child’s small intestine.
Why is Capsule Endoscopy Done?
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.
How should I prepare my child for the procedure?
An empty stomach allows for the best and safest examination, so your child should have nothing to eat or drink, for approximately twelve hours before the examination. Your doctor will tell you when to start fasting.
Tell your doctor in advance about any medications your child is taking 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 any previous abdominal surgery, or previous history of bowel obstructions, inflammatory bowel disease, or adhesions.
Your doctor may ask you to do a bowel prep/cleansing prior to the examination.
What can I expect during a Capsule Endoscopy?
The gastroenterology team will prepare your child for the examination by wrapping a sensor device around his or her abdomen. The pill-sized capsule endoscope is swallowed and passes naturally through the digestive tract while transmitting video images to a data recorder worn on your belt for approximately eight hours. At the end of the procedure your child 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?
Your child will be able to drink clear liquids after two hours and eat a light meal after four hours following the capsule ingestion, unless your doctor instructs you otherwise. Your child will have to avoid vigorous physical activity such as running or jumping during the study. Your doctor generally can tell you the 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 obstruction. 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 your doctor immediately for any such concerns. Also, if your child develops a fever after the test, has trouble swallowing or experiences chest pain, tell your doctor immediately. Be careful not to prematurely disconnect the system as this may result in loss of pictures being sent to your recording device.
