Capsule Endoscopy

A non-invasive test that uses a swallowable capsule with a camera to examine the digestive tract.

What is Capsule Endoscopy?

Capsule endoscopy is an advanced diagnostic procedure that uses a pill-sized capsule equipped with a tiny wireless camera. After swallowing the capsule, it travels naturally through the digestive system, capturing thousands of images that are transmitted to a recorder worn by the patient. This allows doctors to examine areas of the small intestine that are not easily accessible with traditional endoscopy or colonoscopy. Capsule endoscopy is particularly valuable for diagnosing obscure gastrointestinal bleeding, Crohn’s disease, tumors, and unexplained abdominal pain.

This procedure helps to:

Detect bleeding sources in the small intestine.
Identify Crohn’s disease and inflammatory bowel conditions.
Evaluate unexplained abdominal pain or anemia.
Detect small tumors or polyps missed by other tests.
Provide non-invasive imaging without sedation.

What to expect after Capsule Endoscopy?

The test is simple: patients swallow the capsule with water, wear a recording device for 8–12 hours, and go about their normal daily activities. The capsule passes naturally in the stool within 1–2 days.

Painless ingestion of a small capsule.
Ability to continue light daily activities.
Fasting required before the procedure.
No need for anesthesia or sedation.
Capsule expelled naturally without discomfort.

Why is it performed?

To investigate unexplained gastrointestinal bleeding.
To diagnose suspected Crohn’s disease.
To evaluate obscure or recurrent abdominal pain.
To detect small bowel tumors or polyps.
To provide alternatives when standard endoscopy is inconclusive.

Risks and Considerations

Capsule retention in patients with strictures or blockages.
Rare malfunction of the device.
Incomplete imaging if capsule battery expires early.
Limited to diagnostic use (cannot treat findings).
Possible interference with implanted medical devices (rare).

Early detection is important for managing the condition and preventing further complications.
