Capsule Endoscopy (Pill Cam)
What is Capsule Endoscopy?
Capsule endoscopy is a diagnostic procedure that uses a small, swallowable capsule with a camera to examine the small intestine. It is particularly effective in identifying bleeding, tumors, and unexplained abdominal pain, with a detection rate of 60-70% for sources of bleeding. Research is ongoing to expand its use to the gullet and large bowel.
The capsule captures high-resolution images over an 8-hour period, transmitting up to 60,000 images to a data recorder worn around the waist. The procedure is non-invasive and provides a comprehensive view of the gastrointestinal tract.
Preparation
Day Before: Eat a normal breakfast and lunch, then switch to clear fluids (e.g., water, tea, clear juices) after lunch. Avoid milk, soy, red/purple jelly, and solid soups. Fast from midnight.
Day of Procedure: Take your usual medications after lunch unless directed otherwise.
YOUR PROCEDURE
During the Procedure
You’ll wear a harness with a data recorder for 8 hours after swallowing the capsule. Gentle activity is encouraged, but no fluids should be consumed for 2 hours and no solid food for 4 hours after swallowing. Water is allowed to swallow the capsule, and simethicone may be used to reduce bubbles.
After the Procedure
After 8 hours, return to the clinic to remove the harness and data recorder. The capsule will pass naturally in your stool within 1-3 days, and there’s no need to retrieve it.
What are the risks of a Capsule Endoscopy?
Capsule endoscopy is safe, with rare risks such as difficulty swallowing the capsule (<1%) or capsule retention (1%) in the bowel, which may require removal. In 10% of cases, the capsule may show delayed transit, necessitating an X-ray to confirm it has passed.
