What is it for?

To diagnose conditions affecting the oesophagus


An endoscopic ultrasound (EUS) is an outpatient procedure used to examine the upper digestive system and diagnose problems in the oesophagus (food pipe), stomach, pancreas, gall bladder and duodenum (first part of the small intestine).

There are two tests in an endoscopic ultrasound:

Endoscopy – A procedure where the inside of your body is looked at using a long, thin, flexible tube with a camera on it. The tube is passed into your body through your mouth or bottom.

Ultrasound – A scan that uses high-frequency soundwaves to create live images from inside your body.

The benefit of an EUS compared to more traditional scans is that the ultrasound probe gets closer to the area being looked at. This allows the ultrasound to produce higher quality and more detailed images.

At The London Clinic, we offer our endoscopic ultrasound service in our calm and comfortable Endoscopy Unit. Our patients have given the unit a satisfaction rating of over 98%.

Our world-leading gastroenterologists and expert nursing team will oversee your procedure and provide you with exceptional personalised care throughout your time with us.

We’re also the only independent private healthcare provider which offers an EUS service on Saturdays as well as weekdays, making life easier for you.

Why might I need an endoscopic ultrasound?

Your consultant may recommend an endoscopic ultrasound to:

  • Diagnose why you’re experiencing pain, vomiting, swallowing problems or other symptoms affecting your digestive system
  • Drain cysts, pseudocysts or build ups of fluid in your digestive system
  • Target medicine directly into one of your organs
  • Assess abnormal findings from imaging tests such as CT or MRI scans
  • Assess how big and how deep a cancer is in the upper gastrointestinal system

Check if cancer has spread to your lymph nodes or other organs, allowing your consultant to accurately diagnose the extent (stage) of your cancer.

Your endoscopic ultrasound will begin with your consultant giving you medication through a needle or tube inserted into a vein.

This medication reduces pain and discomfort and should make you feel less anxious. You should feel relaxed but be awake during your procedure.

Your consultant may also spray local anaesthetic in the back of your mouth to numb your throat.

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 throat, through your stomach and into the first part of your small intestine (duodenum).

Attached to the end of the tube is a light, camera and ultrasound.

The ultrasound uses sound waves to create high-quality images of lymph nodes, organs and other structures in your upper digestive system.

These include the pancreas, gallbladder, liver and bile ducts.

Your consultant will view images sent by the ultrasound and camera on computer screens next to where you are.

This allows them to pick up on anything that doesn’t look normal and diagnose certain conditions.

During your endoscopic ultrasound scan, your consultant may also use a range of surgical instruments to:

  • Take a sample of body tissue (guided biopsy)
  • Drain cysts, pseudocysts or build ups of fluid
  • Target medicine directly into an organ

An endoscopic ultrasound usually lasts between 20 to 45 minutes, but this will depend on the amount of treatment you require.

Before your endoscopic ultrasound, you'll need to empty your stomach. This is to reduce the risk of you vomiting and to make sure your consultant has clear views of your upper digestive system.

This means you’ll not be able to eat for four to six hours before your procedure.

If you normally take medication or supplements, your care team will also discuss with you if you need to stop taking these and the best times to do so.

After your endoscopic ultrasound, you’ll recover in our calming and comfortable Endoscopy Unit until your medication has worn off and you feel ready to go home.

However, you’ll need someone to travel with you, and we recommend someone stays overnight with you as well.

We also advise that you don’t drink alcohol, drive, work or operate machinery for 24 hours, as you won’t be as mentally alert as usual.

Your expert multidisciplinary team will work closely together to reduce any risk during an endoscopic ultrasound, and support your safe recovery after.

The following risks are more common when a fine needle is used to take a sample of body tissue during the endoscopy:

  • Bleeding
  • Infection
  • Pancreatitis (if body tissue is taken from the pancreas)
  • Tearing (perforation) of the intestinal wall or throat

Your consultant will be able to discuss what they have seen during your endoscopic ultrasound as soon as you feel able to chat.

They may also arrange an appointment to discuss the results of tests carried out on any body tissue removed during your procedure.

These results are usually available in three to four working days.

At this appointment, your consultant will also explain your diagnosis, discuss your treatment options and chat through any worries you may have.
