Capsule Endoscopy is a non-invasive diagnostic technique that consists of the administration of a small device (capsule the size of a vitamin pill) that, when ingested as if it were food, obtains images of the digestive tract during its physiological journey.

This is a minor, non-incapacitating and non-anesthetic procedure in which a capsule equipped with a small battery, transmitter with antenna, and LED light-emitting diodes is swallowed. These components are enclosed in a biocompatible plastic cover to facilitate their transit through the body. It is not necessary to recover it because it is disposable, after 24-48 hours it is expelled spontaneously through the rectum.

The fundamental contribution is the study of pathologies of the small intestine; digestive segment in which there are still diagnostic difficulties with current endoscopy techniques.

Capsule Endoscopy helps doctors see inside the small intestine an area that is not easily reached with more traditional endoscopic procedures.

Why is it done:

  • Discover the cause of gastrointestinal bleeding.
  • Diagnose inflammatory bowel diseases, such as Crohn's disease.
  • Diagnose cancer in the small intestine or other parts of the digestive tract.
  • Diagnose celiac disease.
  • Examine the esophagus and look for abnormal or enlarged veins (varices).
  • Detect polyps.


Its use is contraindicated for the following conditions:

  • Patients with suspected or known obstruction, dysphagia or swallowing disorders.
  • Strictures or fistulas based on the clinical picture or on the tests and profiles obtained before the procedure.
  • Implants such as cardiac pacemakers and other medical devices.



The camera used in Capsule Endoscopy takes thousands of color images as it passes through the digestive tract. The images saved in the recorder are transferred to a computer with special software that stitches the images together to create a video. The doctor will watch the video to look for abnormalities within the digestive tract.

The reading and CD with the images are delivered in two business days, after having completed the exam.
