Enteroscopy
What is it?
The double-balloon enteroscope is a new endoscopic device that allows diagnosis and treatment of small intestine lesions that were previously inaccessible without surgery due to the considerable length of this organ (approximately 8 metres). Designed in Japan by Dr Hironori Yamamoto in 1998 and introduced to the market in 2004, this push-pull endoscope advances through the intestine by inflating and deflating two balloons, allowing treatment (coagulation, polypectomy, sclerosis, and biopsies) of identified lesions. The double-balloon enteroscope at Centro Médico Teknon's Endoscopy Unit is the first to operate in Catalonia, and the only one in a private medical centre in Spain.

When is it used?
The double-balloon enteroscope not only complements the capsule endoscope by treating identified lesions, but also serves as an alternative to its use. It can also be used when the capsule does not detect bleeding lesions that are clinically evident (such as in cases of anaemia), or when examining other small intestine pathologies that were previously inaccessible, unless open or laparoscopic surgery with transmural biopsy sampling is performed.
What are its indications?

- Gastrointestinal bleeding of unknown cause
- Treatment of lesions identified in the jejunum-ileum with capsule endoscopy study indications
- Polyposis
- Study of diarrhoea and abdominal pain
- Suspected small bowel Crohn's disease
- Radiological alterations of the small intestine
- Overtube advancement system (with inflated balloons)
What preparation does the test require?
Preparation is the same as for a colonoscopy, i.e. it requires adhering to a specific diet and consuming a laxative solution the day before the test.
Fasting for 6 hours before the test is required in order to ensure safe sedation.
How is it performed?
The test can be performed on an outpatient basis, under sedation controlled by the anaesthetist; it lasts between 1 and 2 hours, with slight discomfort afterwards due to air insufflated into the digestive tract.
It is performed in the same way as an endoscopy, by inserting the enteroscope through the mouth. In some cases, it must be completed by introducing it through the anus to access the final sections of the ileum.
