K56: Paralytic ileus and intestinal obstruction without hernia

K56.2: Volvulus

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 The large intestine (colon) is where water and salt are withdrawn from the stool.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 lined with mucous membrane. The mucous membrane in the intestines is very sensitive and very well supplied with blood. If an intestinal segment becomes twisted, pressure is then put on blood vessels. The blood supply of the intestinal segment may then deteriorate, resulting in severe damage to it. If an intestinal segment becomes twisted, the intestines may also become obstructed.

If the intestines are obstructed, you may have a lot of air, feces and fluid in your intestines. As a result, your abdomen is usually larger than normal. Most often, you will then no longer be able to have a bowel movement. In that case, the air can generally no longer escape from the anus. If your stomach is pressed, this may feel uncomfortable. You may have severe abdominal pain or have to vomit.
