Examination of the small intestine (single-balloon enteroscopy)
If there is unclear bleeding from the small intestine and a disease is suspected, the small intestine must be examined in detail. This is made possible by the so-called single-balloon technique. The small intestine is examined section by section in steps of around 40 centimeters. The procedure is usually carried out from the oral cavity. If findings are suspected in the lower part of the small intestine, the endoscope is inserted through the anus.
The working channel in the endoscope makes it possible to carry out diagnostic measures without surgical intervention. Various instruments are used for this purpose. For example, tissue samples can be taken or polyps removed.
Before the examination
In preparation, blood coagulation must be checked to rule out a coagulation disorder. A venous line is also inserted. The physician will provide detailed information about the examination. The patient must provide a declaration of consent for the procedure. It is important that the patient is fasting. For a good assessment of the small intestine during an examination via the anus, it must be thoroughly cleaned by means of an irrigation treatment. The prescription for the drinking solution for the irrigation treatment (e.g. Kleanprep®, Endofalk®) is issued by the attending physician or in our outpatient clinic. Patients should urgently follow the instructions for such an irrigation treatment.
