You have undergone an endoscopic examination of the digestive tract.

Various organs are required for digesting food. The upper digestive organs are the mouth, oesophagus, stomach and the first segment of the intestines. The liver, along with the gallbladder and the pancreas, also form part of the upper digestive organs. The lower digestive organs are the rest of the intestine and the anus.

The endoscopic examination involves a thin tube being passed into the body, then advancing it to the digestive tract. The tube may be passed into the body through the mouth or the anus. However, access may also be obtained through an incision in the skin. There is a camera at the top of the tube. This camera is used to transmit images from inside the body to the outside during the examination. In this way, the inside of the digestive tract can be viewed and assessed for any changes.
