Endoscopic ultrasound or EUS is an innovative investigation that combines two types of tests, endoscopy, and ultrasound. EUS allows The London Clinic's world-leading gastroenterology consultants to perform detailed examinations of the upper digestive system and diagnose problems in the oesophagus, stomach, duodenum, pancreas, and gall bladder.

The London Clinic has a state-of-the-art Endoscopy Unit. As the only independent, private clinic providing a Saturday service, the clinic is dedicated to offering patients the very latest investigations and greater flexibility and choice over when to access them. 

The London Clinic provides endoscopic ultrasound in a private, comfortable, and calm environment. With cutting-edge equipment and care by an expert multidisciplinary team, our patients have given the Endoscopy Unit a satisfaction rating of between 98 and 100%.

An endoscopic ultrasound is a procedure where a flexible telescope is used to look at the lining of your oesophagus, stomach and duodenum. 

What is endoscopic ultrasound (EUS)? 

Endoscopic ultrasound is a minimally-invasive investigation used to assess a range of gastrointestinal conditions. 

The London Clinic’s gastroenterologists use fine, flexible telescopes, with ultrasound built into the tips, to examine the lining of the gastrointestinal system and perform scans. Because the ultrasound probe gets closer to the area being investigated, the images are of higher quality and offer more detailed information.

The consultant introduces the endoscope through the mouth and passes it through the stomach into the beginning of the small bowel. The ultrasound probe uses high-frequency sound waves to produce images of the lymph nodes, organs, and structures in the area, including the pancreas, liver, gall bladder, and bile ducts.

Who can benefit from endoscopic ultrasound?

Endoscopic ultrasound can be useful in investigating several gastrointestinal problems:

  • To diagnose the cause of pain, nausea, problems swallowing, and other symptoms affecting your digestive system. 
  • To further investigate abnormalities seen on imaging tests such as CT or MRI scans.
  • To evaluate the size and local penetration of cancers of the upper gastrointestinal system.
  • To check whether cancer may have spread to lymph nodes or other organs, allowing more accurate staging of the disease.
  • To examine the pancreas and drain any cysts, pseudocysts, or fluid collections.
  • To target medication directly into organs.

Treatment options

MRI scanning and CT scanning can also provide images of the upper gastrointestinal system. However, EUS often gives better information because the probe is closer to the structures being investigated. 

Endoscopic ultrasound consultation at The London Clinic

Our experienced gastroenterologists will assess and advise you in The London Clinic's comfortable, well-equipped consulting rooms. They will take a detailed medical history, examine your abdomen, and ask about the impact your symptoms have on your health, wellbeing, and quality of life.

Your consultant may arrange tests and investigations in the cutting-edge imaging suite. These may include:

  • Blood tests to check for anaemia, liver function, and tumour markers
  • Ultrasound
  • MRI or CT scanning

In consultation with you, your urologist will then plan your EUS, explain what will happen during the procedure, and advise you about any preparation needed. They will take the time to answer all your questions and address your concerns.

Endoscopic ultrasound at The London Clinic

Your consultant will perform the investigation as an outpatient procedure. At The London Clinic, the specialists offer sedation to reduce discomfort and anxiety. The anaesthetist will administer this intravenously, so that you will feel relaxed but still conscious.

Your consultant will spray a local anaesthetic in your mouth to numb your throat. 

They will then insert a thin, flexible tube into your mouth. They may ask you to swallow, to help the endoscope pass down your throat, through the stomach, and into the small intestine. 

As well as the ultrasound probe, there is a small camera on the end of the device, which relays high-quality images to a computer screen. Your consultant will use both sources to record images and precisely take biopsies.

Recovery and aftercare

After your investigation, you will recover in the comfort and privacy of The London Clinic Endoscopy Unit. The team will offer support until the sedation has worn off and you are alert and well. 

You will need an escort to take you home and to stay with you overnight. You should avoid alcohol and shouldn’t drive, work or operate machinery for 24 hours, as you won’t be as mentally sharp as usual until the sedative has passed through your system.

Your consultant will be able to discuss their visual findings as soon as you feel alert and able. They may then arrange an appointment to discuss the results of any biopsies. Pathology laboratory results are usually available in 3 to 4 working days. They will take time to explain your diagnosis, address any worries that you have, and plan a personalised treatment strategy.
