Capsule Endoscopy

What Is Capsule Endoscopy?

Capsule endoscopy is a diagnostic procedure that uses a tiny wireless camera in a pill-sized capsule to capture images of the digestive tract. Swallowed by the patient, the capsule transmits photos to a recorder worn around the waist, providing detailed visuals of areas like the small intestine, not easily accessible with traditional endoscopies.

How Does Capsule Endoscopy Work?

Before beginning the capsule endoscopy process, you will be equipped with a sensor belt that is designed to capture and store pictures taken by the camera pill as it navigates your digestive tract.
The belt should remain on for 8-10 hours. After connecting and preparing the recorder, you will be instructed to swallow the camera capsule with water. The capsule has a slippery coating which makes swallowing very comfortable and painless.

Common Questions about Capsule Endoscopy

How should I prepare for a colonoscopy?

Discuss Medical History: Inform your doctor about your medical conditions and medications. Adjust or stop certain medications if needed. Adjust Your Diet: Avoid high-fiber foods two days before and switch to a clear liquid diet before the procedure. Take Necessary Medications: Inform your doctor of all medications, including over-the-counter ones. Adjust or stop certain medications as advised. Bowel Cleansing Preparation: Follow instructions to drink a special solution to flush out the colon for clear visibility. Fast Before Procedure: Fast for at least 6 hours before the procedure; clear liquids may be allowed up to 4 hours prior.
How soon will I receive the results after my colonoscopy?

Your healthcare provider will discuss the findings shortly after the procedure. In some cases, biopsies may be taken during the colonoscopy, and results from these tests may take a little longer to process. Your specialist will follow up with you in clinic to discuss further results in detail.
Is there any possible discomfort or risk during and after the colonoscopy?

While complications are rare, they may include bleeding, perforation of the colon, or adverse reactions to sedation. The risk of bleeding and perforation is usually around 0.1% (or 1 in 1000), these are usually related to the therapeutic procedure undertaken during the colonoscopy, for example, removal of polyps. Your healthcare provider will discuss the potential risks and address any concerns you may have.
Are there restrictions following a colonoscopy?

It is recommended to avoid strenuous activities and heavy lifting for at least 24 hours after the procedure. Your healthcare provider may also advise you to avoid certain medications, such as blood thinners, for a period. If biopsies were taken during the colonoscopy, your doctor may provide specific instructions on how to care for the area where they were taken.
What can I eat after the colonoscopy?

After the procedure, you may need some time to recover from the sedation. Your healthcare provider will provide guidance on when it’s safe to resume eating and drinking. Typically, it is recommended to stick to a light diet initially, and then gradually reintroduce solid foods. Avoid heavy or spicy meals that may irritate your digestive system. Foods that are easy to digest, such as soup, crackers, and toast, are usually recommended for the first meal. It is also important to drink plenty of fluids to flush out the remaining sedation medication from your system.
Do I need a second colonoscopy if my first one was normal?

The recommended frequency for a routine colonoscopy depends on individual risk factors, such as family cancer history, personal health history and the number of polyps removed during the index colonoscopy. It is best to follow the advice of your healthcare provider regarding when to schedule your next screening. In some cases, a second colonoscopy may be necessary if there are abnormal findings or persistent symptoms after your first procedure. Your doctor will discuss the need for further tests or procedures with you.
