Double balloon enteroscopy


Double balloon enteroscopy is another method of examining the small bowel. With a 2 m long imaging instrument and two inflatable balloons, which are attached to the endoscope and which are alternately inflated and deflated, it is possible to advance through, and examine, the 3–4 meters long small bowel.

Indications and treatment

Indications and treatment are the same as for capsule endoscopy; the procedure is used specifically for gastrointestinal (GI) bleeding of unknown origin, or where the outcome of the capsule examination indicates that further investigation is needed. Double balloon enteroscopy is also a method for investigating abnormal radiological findings, suspected Crohn’s disease and unexplained chronic diarrhea.

In contrast to capsule endoscopy, double balloon enteroscopy allows certain therapeutic or investigative procedures: polyps can be removed, certain types of bleeding can be treated, strictures be dilated and samples can be taken from the intestinal mucosa.

Waiting time

The waiting time for this procedure is about 4 weeks. If necessary, we can offer a shorter waiting time, generally 1 week; contact us by phone at 019-602 18 79. Results are provided immediately after the examination, unless tissue samples are taken; the report for these takes about 4 weeks.


The examination is an evaluation of the small bowel and the patient will be informed of the results. The referring doctor is responsible for overall assessment of the patient’s symptoms.

In order for the intestine to be examined, it must be clean. Patients who take iron pills must stop taking them 1 week before the examination. Patients on Coumadin need to have a blood sample drawn for an international normalized ratio (INR) test.

Patients should avoid fruit, vegetables and whole grain bread, especially with flaxseed and similar, for at least 2 days before the examination.

The day before the examination, the patient is to begin taking the bowel preparation: he or she should eat a light lunch, such as chicken, steamed fish, or ham, and rice or potatoes. The patient should start drinking Laxabon no earlier than 2 hours after lunch, and should drink 2 liters of the solution within the next 2–2.5 hours. The patient may drink unlimited amounts of clear liquid, such as coffee or tea ( without milk), juice, or broth, after taking the bowel prep.

On the day of the examination, the patient should not drive because an anesthetic may be given during the procedure if needed. Nail polish and jewelry should not be worn. After the examination, the patient will remain at the clinic for 1 more hour.
