Double (Bi-Directional) Endoscopy Q & A

What is a bi-directional endoscopy?

Bi-directional endoscopy ("double") is a procedure that includes an upper endoscopy and a colonoscopy. The upper endoscopy looks at the lining of your esophagus, stomach, and the first part of your small intestine (duodenum), while the colonoscopy evaluates the lining of your large intestine. The group of board-certified gastroenterologists at Gateway Gastroenterology specialize in these types of endoscopic procedures. 

Am I a candidate for bi-directional endoscopy?

The skilled healthcare providers at Gateway Gastroenterology determine if you’re a candidate for a "double" after an initial consultation. That is true even when requested by your primary care provider. They need to make sure you’re an appropriate candidate to undergo both procedures on the same day.

This “double” procedure was once routine. However, current research indicates that "double" may have uncertain benefits for most patients and is of low value, adding unnecessary costs to health care. 

There’s also a concern about aspiration during this procedure because patients have more liquid in their stomachs for preparation for the colonoscopy. Though aspiration is a risk during any procedure, the amount of liquid aspirated during a routine endoscopy is small and usually causes coughing and bronchospasm but not a pulmonary infection or hospitalization.

How do I prepare for a bi-directional endoscopy?

The healthcare providers at Gateway Gastroenterology provide specific guidelines for how to prepare for your "double". Preparation may include stopping blood thinners (including blood-thinning supplements) prior to the procedure.

You also need to modify your diet in the days preceding your "double", follow the bowel prep program for the colonoscopy, and stop eating at a set time before the procedure.
