You have had a colonoscopy.

The intestines are made up of the small intestine and the large intestine or colon. Most of the nutrients are absorbed in the small intestine. The large intestine (colon) is where water and salt are withdrawn from the stool. The last segment of the large intestine (colon) is the rectum. Stool then leaves the body through the anus. The last segment of the large intestine consists of 2 sections. These 2 sections are the rectum and anal canal. The feces are collected in the rectum. The feces then move through the short anal canal to the anus. Feces are excreted through the anus.

You have an artificial anus. This has been used to examine the lower section of your rectum. A variety of test devices are available for a colonoscopy. For example, a flexible tube with a camera attached to the front end can be used. A rigid tube can also be used for the test. The flexible or rigid tube is inserted into the intestine via the stoma. The camera on the tube can send images of the intestine to a screen. The tube also enables intestinal tissue to be viewed and studied. Both the flexible and rigid tubes can be used to take tissue samples.
