Enteroscopy is a procedure used to examine the small intestine (small bowel).
Small bowel biopsy; Push enteroscopy; Double-balloon enteroscopy; Capsule enteroscopy; Sonde enteroscopy
A thin, flexible tube (endoscope) is inserted through the mouth and into the upper gastrointestinal tract. During a double-balloon enteroscopy, balloons attached to the endoscope can be inflated to allow the doctor to view a section of the small intestine.
In a colonoscopy, a flexible tube is inserted through your rectum and colon. The tube can most often reach into the end part of the small intestine (ileum).
Tissue samples removed during enteroscopy are sent to the lab for examination.
Do not take products containing aspirin for 1 week before the procedure. Tell your doctor if you take blood thinners such as warfarin (Coumadin) or clopidogrel (Plavix), because these may interfere with the test. Do NOT stop taking any medication unless told to do so by your health care provider.
Do not eat any solid foods or milk products after midnight the day of your procedure. You may have clear liquids until 4 hours before your exam.
You must sign a consent form.
