Capsule Endoscopy
Back to the nypdigestive.org Home Page
New York-Presbyterian's gastrointestinal specialists are using a new, non-invasive technique called capsule endoscopy (also known as a "camera pill") to view the entire internal lining of the esophagus and small intestine and help diagnose formerly undetectable abnormalities and digestive diseases.
For this procedure, patients swallow a disposable pill-like device (about the size of a large vitamin) that contains a small camera. The camera transmits images via radiofrequency as the device moves down the esophagus, through the stomach, and to the small intestine. The data go to a recorder worn by the individual, usually as a belt around the waist.
The procedure is completed within a half hour for an esophageal exam and about eight hours for a small intestinal exam.
The capsule is also being studied for use in patients with other GI conditions, such as celiac disease and familial adenomatous polyposis (FAP).
Capsule Endoscopy in the Small Intestine
In the small intestine, capsule endoscopy can be used to:
- identify small intestinal polyps or tumors
- determine the source of unidentified intestinal bleeding
- evaluate inflammatory changes in patients suspected of having Crohn's disease
Capsule Endoscopy in the Esophagus
In the esophagus, capsule endoscopy is a non-invasive option for detecting:
- varices
- esophagitis
- Barrett's esophagus in patients with gastroesophageal reflux disease (GERD)
