About Endoscopy

Endoscopy ACT

Endoscopy is a medical procedure that allows a doctor to observe the inside of the body without performing major surgery.

An endoscope is a long flexible tube with a lens at one end and a video camera at the other. The end with the lens is inserted into the patient. Light passes down the tube (via bundles of optical fibres) to illuminate the relevant area, and the camera magnifies the area and projects it onto a television screen so that the doctor can see what is there. Usually an endoscope is inserted through one of the body’s natural openings, such as the mouth (Gastroscope), or anus (Colonoscope).

GASTROSCOPY

The doctor looks at the lining of the food pipe (oesophagus), stomach and duodenum (first part of the small bowel).

The patient will be given sedation to help them relax. They will then lie on their left side, and the doctor will pass the tube into their mouth and down their food pipe (oesophagus), stomach and duodenum (small bowel leading from the stomach).

The endoscope does not cause problems with breathing.

COLONOSCOPY

The doctor looks at the lining of your large bowel (colon) to see if there are any growths or disease.

The patient lies on their side side or back while the doctor slowly passes the colonoscope along the large intestine to look at the lining. The doctor will also examine the lining again as the colonoscope is taken out. The patient may feel some pressure, bloating or cramping during the procedure.
