You have had a colonoscopy (examination of the large intestine).

The large intestine (colon) is like an upside down U in the abdomen. The first part lies in the lower right corner of the abdomen. Then it continues upwards and runs across from right to left. Then it descends again. There then follows an S-shaped part located on the bottom left side of the abdomen, which then merges into the rectum. The rectum is the last section of the large intestine (colon).

The endoscopic examination involves a thin tube being passed into the body, then advancing it to the large intestine. The tube may be passed into the body through 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 large intestine can be viewed and assessed for any changes.
