Welcome to our Patient Education page!
Commonly called colon cancer – is preventable. The best way to beat it is to stop it before it starts. A gastroenterologist can perform a screening procedure to detect and remove precancerous polyps before they become malignant. More than 60% of cancer deaths could be avoided through regular screening. Colonoscopies save lives. The most effective screening method is a colonoscopy, a visual examination of the entire colon (large intestine) using a lighted, flexible endoscope. The procedure is painless and typically performed on an outpatient basis. (And it saves lives.)
What you should know about colon cancer:
- It affects women and men of all ethnicities.
- It’s the second leading cause of cancer deaths in the U.S.
- It’s most often found in people aged 50 and older.
- In its early stages, there are often no symptoms.
Early stage colon cancer may not present symptoms. However, symptoms of advanced stages include rectal bleeding, blood in the stool, change in bowel habits, abdominal cramping, decreased appetite or weight loss. If any of these signs occur at any age, evaluation with a gastroenterologist is critical to diagnose the condition. We have listed additional information in the side column of this page.

To assist you in achieving optimal health, we have listed some information regarding gastrointestinal conditions, procedures, and treatments available.

What is capsule endoscopy?
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 and ileum). Your doctor will give you 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 wear on your 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 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. As is the case with most new 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.
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 can I expect during capsule endoscopy?
Your doctor will prepare you for the examination by 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, unless your doctor instructs you otherwise. You 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 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.
