Your small bowel enteroscopy will begin with your consultant giving you medication through a needle or tube inserted into a vein.Â
This medication reduces pain and discomfort and should make you feel less anxious. You should feel relaxed, but be awake during your procedure.Â
Your consultant may also spray local anaesthetic in the back of your mouth to numb your throat.Â
They’ll then insert a long, thin, flexible tube (endoscope) into your mouth. They may ask you to swallow to help the endoscope pass down your throat. You shouldn’t feel any pain at this point.
The tube is passed down your oesophagus (gullet), through your stomach and along the full length of your small intestine.Â
There is a small camera on the end of the endoscope that sends high-quality images to a computer screen.
Your consultant looks at the screen during the investigation to pick up on anything that doesn’t look right.
During the enteroscopy, your gastroenterologist may take a sample of body tissue (biopsy), remove bowel polyps and stop bleeding by cauterising (burning) tissue.Â
An enteroscopy usually lasts around 45 minutes, but this will depend on the amount of treatment you require.
