Understanding Capsule Endoscopy
How should I 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. 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 or defibrillator, 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 are the possible complications of capsule endoscopy?
Although complications can occur, they are generally rare when doctors who are specially trained and experienced in this procedure perform the test. There is a 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 is 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 you develop a fever after the test, have trouble swallowing or experience 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.
