The London Clinic Endoscopy Unit is a purpose-built facility which allows complete examination of either the upper gastrointestinal (GI) tract or the lower GI tract. 

Our Endoscopy unit is open six days a week. Having a Saturday service gives patients more flexibility and choice and is particularly useful to those patients who find it difficult having time off during the working week. We are the only dedicated private hospital to be able to offer comprehensive endoscopy services on a Saturday. 

An endoscopy is used to investigate all parts of the digestive system. Upper gastrointestinal (GI) endoscopy and lower GI endoscopy (colonoscopy) are generally performed by physician or surgeon gastroenterologists who have specialised in these techniques.

Gastroenterologists at The London Clinic offer screening (including bowel cancer screening), diagnosis and treatment for diseases that affect any part of the digestive system, from the upper oesophagus, stomach and small intestine right through to the colon, rectum and anus.

Some of our consultants specialise in endoscopic examination of the small bowel and of the pancreatic and bile ducts.

The calm, modern, and relaxing spaces provide an enhanced environment - enabling our consultants to give the best possible treatment to our patients.

Endoscopic investigations

Our specialist consultants offer all forms of endoscopic investigation to diagnose problems with the digestive system:

A video capsule, which looks like a large pill, is swallowed and its on-board camera takes pictures of the inside of your digestive system as it passes through.

Capsule endoscopy

This is the most frequent form of endoscopy carried out at The London Clinic. The aim of a colonoscopy is to examine the large bowel to investigate the causes of diarrhoea or rectal bleeding. Polyps are routinely removed, reducing the risk of developing colon cancer in the future.


This investigates the oesophagus and stomach. Gastroscopy is used to identify problems such as oesophageal narrowing, heartburn, Barrett’s oesophagus, ulcers, cancer and other conditions.

 A combination of two types of test - endoscopy and ultrasound. The endoscopist uses an endoscope with an ultrasound probe built into the tip to take samples and create detailed pictures of the body, including the lungs, pancreas, liver, gallbladder, oesophagus and stomach.

The word endoscopic refers to the use of an endoscope, which is the long, thin, tube with a minute video camera that your physician uses to explore inside your digestive system.

Retrograde refers to the fact that a dye is injected to help your bile and pancreatic duct show up better on an X-Ray. Finally, cholangiopancreatography means the process of taking the X-Rays.


Gastroscopy is a visual examination of the gullet, stomach and first part of the small bowel beyond the stomach (duodenum). For enteroscopy, a longer instrument is used to examine the upper part of the small bowel.


Similar to a gastroscopy but using longer endoscopic equipment to examine further into the small bowel.

These endoscopic tests are done to find out why you may be having swallowing problems, or to assess acid reflux.
