A dedicated endoscopy unit is provided at each hospital site, offering both diagnostic and therapeutic upper and lower endoscopy. We perform in excess of 15,000 procedures per year. The types of procedures performed are detailed below:

Upper Gastrointestinal Endoscopy [OGD]

An OGD is a procedure which an enables your doctor to view the lining of your oesophagus, stomach, and first part of your small intestine. A small camera is inserted into your mouth, and it can be used to look for ulcers, inflammation, narrowing of the oesophagus, or bleeding. In addition, OGD can be used to help to take tissue samples, and is currently the best way to visualise the lining of the upper gastrointestinal tract.

Flexible Sigmoidoscopy

A sigmoidoscopy examines the last part of the colon (this makes it different to a colonoscopy, which can examine the whole of the colon). A flexible endoscope – a very small camera on the end of a long, thin tube – is inserted into the rectum, and used to examine the large intestine in cases of, for example, diarrhoea, abdominal pain, or rectal bleeding. The detection of polyps and cancers are also common reasons for performing a flexible sigmoidoscopy.

A colonoscopy is a procedure which enables doctors to examine the entire colon and a part of the small bowel called the ileum. It is mainly used for the detection of inflammation, polyps and cancers in the large colon. It also enables the taking of samples for biopsy, as well as removal of most polyps.

Endoscopic Retrograde Cholangiopancreatography

Combining endoscopy and fluoroscopy (a special X-Ray test using dyes to show up internal structures better), ERCP can be used to diagnose and treat problems of the bile ducts and pancreas. Dyes are injected into the bile duct and sometimes the pancreas by the use of a specialised endoscope and then a picture is generated of the bile ducts by the use of X-rays. Gallstones, cancers and inflammation can be detected, diagnosed and treated using ERCP.

Endoscopic Ultrasound

In this procedure, ultrasound imaging – similar to that used with pregnant mothers – is utilised to obtain images of the internal organs of the chest and abdomen, making it particularly useful for observation of the upper digestive tract. The patient will experience this procedure as very similar to a standard endoscopy; the ultrasound element merely enables the doctor to achieve a better visualisation of the walls of the target organs, and surrounding structures, and is particularly useful at diagnosing and sampling various cancers, including gastric and pancreatic cancers.
