Capsule Endoscopy
Capsule endoscopy is a non-invasive diagnostic tool that involves swallowing a small, pill-sized camera to capture images of the digestive tract. This procedure is primarily used to detect abnormalities in the small intestine, such as bleeding, polyps, or Crohn’s disease, areas that are difficult to reach with traditional endoscopy.
Overview
Capsule endoscopy uses a pill-sized camera that is swallowed by the patient. As the capsule travels through the digestive tract, it captures thousands of images that are wirelessly transmitted to a recording device worn around the waist. The images provide a detailed view of the small intestine, which is difficult to reach with traditional endoscopy.
Purpose of the Procedure
Capsule endoscopy allows for the visualization of the small intestine, identifying bleeding, tumors, and inflammatory conditions that are often undetectable through traditional endoscopy or colonoscopy.
How to Prepare
For capsule endoscopy, patients need to fast before swallowing the capsule. Patients are instructed to avoid strenuous physical activity during the test period and may be advised to take a laxative the night before to improve visualization of the small intestine.
What to expect after
Once capsule endoscopy is completed, patients can resume eating and drinking within a few hours. Normal activities are allowed, but heavy lifting or strenuous exercise should be avoided until the capsule passes, typically within 24 to 48 hours. Patients may not feel the capsule as it exits the body.
Complications & Risk
Capsule endoscopy is a non-invasive procedure with minimal risk. However, there is a small chance that the capsule may become lodged in a narrowed section of the digestive tract, potentially causing a blockage. This risk is higher in patients with Crohn’s disease or strictures. Capsule retention may require surgical removal or endoscopic retrieval.
Results and Follow-up
Capsule endoscopy results are typically available within a week after the capsule has passed. The images captured are reviewed by the doctor to detect abnormalities such as bleeding, polyps, or tumors. If issues are identified, additional procedures such as biopsies or traditional endoscopy may be necessary for further evaluation or treatment.
