Enteroscopy, also called push enteroscopy, is a procedure that examines the small intestine, a very long area of small bowel located between the stomach and colon (large intestine) and made up of the duodenum, jejunum and ileum. The first few feet of the small intestine ‒ the duodenum and first portion of the jejunum ‒ can be examined by using this longer endoscope (enteroscope), where the instrument is introduced through the mouth and slowly advanced through the stomach, duodenum and into the jejunum by a gentle pushing action.
Your surgeon may recommend push enteroscopy if there is a suspected abnormality in the upper portion of your small bowel that may be causing recurrent or persistent symptoms, including:
This advanced procedure is often used as a follow up to other diagnostic testing such as upper endoscopy, colonoscopy, capsule endoscopy or radiology imaging tests.
Speak with your doctor.
You should speak with your doctor about any health problems that you have and all prescribed and over-the-counter medicines, vitamins, and supplements you take such as:
• aspirin or medicines that contain aspirin
• blood thinners/ anti-coagulants
• herbal supplements or vitamins that contain iron
• Inform your physician of any special needs, medical conditions (such as a defibrillator) or current medications you are taking that may require advanced planning prior to undergoing push enteroscopy.
The procedure takes about 25 to 45 minutes. You will go home the same day.
Before the procedure begins:
You may be given medicine to help you relax or sleep (sedation). This is given through an IV (intravenous) line placed in a vein in your arm or hand. Your throat may be numbed with a spray or liquid. You will be given a small plastic guard to protect your teeth.
During the procedure:
• You will lie on your left side. The tube is placed in your mouth, and it moves down your throat. Air is used to expand your GI (gastrointestinal) tract so the lining can be seen more clearly.
• The tube is guided down your esophagus. It then goes through your stomach and into your small intestine.
• The tube sends pictures of the GI tract to a screen.
• The esophagus, stomach, and small intestine are checked for problems such as bleeding, redness or swelling (inflammation), or growths may be seen. Using tools inserted through the tube, small tissue samples can be taken. In some cases, small growths can be removed.
• The tube is then removed.
