K56.4: Other impaction of intestine

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 The large intestine (colon) is where water and salt are withdrawn from the stool.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 intestines are like a tube. There is a hollow space on the inside. The intestinal wall lies around this hollow space. For example, the intestines may be obstructed by a fecalith or gallstone. Fecaliths can develop when the feces becomes solid and is deposited in the intestines.

If the intestines are obstructed, you may have problems with your bowel movement. You may also have abdominal pain. It is possible that you will have to vomit.
