What is Gastroenterology?

Gastroenterology is the branch of medicine that looks at diseases of the oesophagus (gullet), stomach, small and large intestines (bowel), liver, gallbladder and pancreas. 

The oesophagus is the tube that joins your mouth with your stomach. It is a muscular tube that contracts to push the food through when you swallow.

The stomach is where food is broken down by acid and emptied into your intestines. The stomach has special cells lining its wall to protect it from these acids.

The intestines consist of the small intestine (duodenum, jejunum and ileum – different sections of small intestine) and the large intestine (colon).  As food passes through the small intestine, nutrients are broken down and absorbed.  When it passes into the colon, water is absorbed.  The waste that is left is passed as faeces (poo).

The liver is roughly the size of a football and is on your right side just under your ribs. It stores vitamins, sugar and iron which are used by cells in the body for energy.It also clears the body of waste products and drugs, produces substances that are used to help blood clot and aid the immune system, and produces bile which aids in digestion.

The pancreas is an elongated organ that lies in the back of the mid-abdomen. It is responsible for producing digestive juices and certain hormones, including insulin, the main hormone responsible for regulating blood sugar.
A gastroenterologist is a doctor specialising in the field of medicine which involves these closely related organs. 

What is Endoscopy?

Endoscopy is the process of looking inside body cavities, using a very tiny camera attached to the end of a long, flexible tube (endoscope). Images from the camera are sent to a television monitor so that the doctor can direct the movement of the endoscope. It is also possible to pass different instruments through the endoscope to allow small samples or growths to be removed.

Endoscopy allows a doctor to make a diagnosis either by seeing directly what is causing the problem or by taking a small tissue sample for examination under a microscope (biopsy).
Endoscopy can also be used as a treatment e.g. for removal of swallowed objects in the oesophagus (food pipe), healing of lesions etc.


Referral Expectations

Your GP will refer you to me if they are concerned that you have problems that require a specialist opinion regarding the diagnosis or treatment of the condition. 
At the appointment, a history of your symptoms will be taken as well as a review of any medications you are on (please bring these with you).  You will then be examined which may involve, depending on your complaints, a rectal examination.  This involves the insertion of the doctor’s finger or a tube into your bottom to examine the inside.
You may be referred on for some of the following radiology tests, depending on your condition: ultrasound scan, CT scan or MRI.
