What is double-balloon enteroscopy?

Double-balloon enteroscopy (DBE), also known as push-pull enteroscopy, is a procedure that can examine and treat abnormalities in the small intestine between the stomach and the colon (large intestine). It is typically recommended when abnormalities are found during another procedure—such as capsule endoscopy or other imaging studies—following symptoms that include:

Anemia
Abdominal pain
Bleeding
Diarrhea

How does DBE differ from a capsule endoscopy?

While both procedures allow a physician to see the entirety of the small bowel, during DBE:

Tissue samples (biopsies) may be collected along the way for further testing
Stents —small tubes to keep vessels or ducts open— can be placed, or strictures—a narrowing of a vessel or other structure—can be widened
Everything in the small bowel can be seen up to the terminal ileum, the third and last section of the small bowel.

How is the procedure performed?

During the procedure, two tubes (one inside the other) are inserted through the rectum or mouth into the small intestine.

The inner tube, which functions as a lighted scope (endoscope), is guided through a section of the small intestine and secured in place with an inflated balloon.
Next, the outer tube is moved through the small intestine until it reaches the end of the inner tube, and a second balloon is inflated to secure the outer tube
Next, the balloon that holds the inner tube is deflated, allowing the tube to move through another section of the small intestine.
These steps are repeated until the tubes have completely passed through the small intestine.

Is there any recovery time?

DBE is a same-day, outpatient procedure with no real recovery required. However, since DBE can be done under general anesthesia or through conscious sedation, patients will be unable to drive and will have to coordinate a ride home.
