Double-balloon enteroscopy allows for the entire gastrointestinal tract to be visualized in real time.
The technique involves the use of a balloon at the end of a special enteroscope camera and an overtube, which is also fitted with a balloon.
The procedure is usually done with the use of conscious sedation.
The enteroscope and overtube are inserted through the mouth and passed in conventional fashion (that is, as with gastroscopy) into the small bowel.
Following this, the endoscope is advanced a small distance in front of the overtube and the balloon at the end is inflated.
Using the assistance of friction at the interface of the enteroscope and intestinal wall, the small bowel is accordioned back to the overtube.
The overtube balloon is then deployed, and the enteroscope balloon is deflated.
The process is then continued until the entire small bowel is visualized.
Double-balloon enteroscopy allows for the sampling or biopsying of small bowel mucosa.
Liquid meal consisting of 100 g "Ny NAN" dissolved in 300 ml water (ca.
5000 kJ) to be ingested over 5 minutes.
Blood will be sampled for 4 hours following ingestion.
Samples are centrifuges and plasma will be analysed for glucagon, GLP-1, GIP, insulin and C-peptide concentrations.
