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 The large intestine (colon) is where water and salt are withdrawn from the stool.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 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).

You have an artificial anus. It has been used to examine the S-shaped part of your large intestine. 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.
