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 or nose 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 large part of the small intestine.
In a colonoscopy, a flexible tube is inserted through your rectum and colon. The tube usually can reach into the end part of the small intestine (ileum). See also: Colonoscopy
Tissue samples removed during enteroscopy are sent to the laboratory 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.
When the tube is put into your mouth and down your esophagus (food pipe), you may feel like gagging. You will get a numbing medicine to reduce this feeling.
You may get a mild sedative, but only in small doses because you must stay alert enough to help with the procedure (by doing such things as swallowing and turning). The biopsy sampling causes little or no pain, although you may have some mild cramping.
This test is most often performed to help diagnose diseases of the small intestines. It may be done if you have:
