Capsule Endoscopy

CAPSULE ENDOSCOPY

Capsule endoscopy is a non-invasive diagnostic procedure used to examine the inside of the gastrointestinal (GI) tract, particularly the small intestine, using a capsule-shaped camera that is swallowed by the patient. It captures images as it travels through the digestive system, providing a detailed view of areas that may be difficult to reach with traditional endoscopy or imaging techniques.

What is Capsule Endoscopy?

Capsule endoscopy is a non-invasive diagnostic procedure in which a small, swallowable capsule with a camera inside is used to take images of the inside of the gastrointestinal (GI) tract. It is primarily used to visualize parts of the small intestine that are difficult to reach with traditional endoscopy.

A capsule endoscopy is a non-invasive procedure that uses a capsule-shaped camera to examine the inside of your digestive tract. It’s also known as a pill camera or wireless endoscopy.

Why is Capsule Endoscopy Performed?

Capsule endoscopy is commonly used for:

Diagnosing GI disorders: It is especially useful for detecting problems in the small intestine (e.g., Crohn's disease, celiac disease, ulcers, or small intestine tumors).
Bleeding: Identifying the source of unexplained gastrointestinal bleeding, such as from the small intestine.
Assessment of Crohn's disease: Monitoring the progression or flare-ups of Crohn’s disease when other diagnostic methods are inconclusive.
Tumor detection: Identifying tumors, polyps, or lesions in the small intestine.
Evaluation of obscure GI bleeding: When traditional endoscopy or colonoscopy does not find the source of bleeding.

Procedure Overview:

Preparation:
Fasting: Patients are required to fast for 12-14 hours before the procedure to ensure clear visibility.
Bowel preparation: Depending on the indication, patients may need to take a mild laxative to clear the intestines.
Capsule Ingestion:
The patient swallows a small capsule (about the size of a large pill). This capsule contains a tiny camera, light source, and transmitter.
The capsule is coated to withstand stomach acid and begins its journey through the digestive tract.
Monitoring:
During the procedure, a sensor belt or external recording device is worn by the patient to capture images sent from the capsule.
The capsule takes thousands of pictures as it moves through the GI tract, sending them to a data recorder worn by the patient.
Completion:
The procedure usually lasts between 8-12 hours as the capsule passes through the digestive system.
The patient can resume normal activities, but they should avoid heavy lifting or strenuous exercise.
Capsule Elimination:
The capsule is naturally passed out of the body through the stool, usually within 24-48 hours.
The patient may be asked to return for a follow-up to ensure the capsule has been excreted.

Risks and Aftercare:

Minimal risk as it is a non-invasive procedure.
Rare risks: The capsule may get stuck in the intestines (usually due to a narrowing or stricture), which could require removal by endoscopy or surgery.
Aftercare: There are typically no dietary restrictions after the procedure, though patients may be asked to monitor for any discomfort or signs that the capsule hasn’t passed.
Follow-up: The images are reviewed by a gastroenterologist who will analyze the findings and make treatment recommendations if necessary.
