K56.5: Intestinal adhesions [bands] with obstruction

You have adhesions in your abdomen. As a result, your intestines are constricted.

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 The large intestine (colon) is where water and salt are withdrawn from the stool.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. Adhesions have formed in your abdomen. Such adhesions can develop after operations. During operations, thin, soft strands of tissue are often cut through on the organs in the abdomen. The separated strands of tissue may grow again on other organs and adhere to each other. Even after severe inflammations, tissue can adhere in the abdomen. The adhesions have pressed on your intestines from the outside and thus constricted the intestines.

If the intestines are constricted, you may have problems with your bowel movement. You may also have abdominal pain. It is possible that you will have to vomit. If the intestines are much narrower than usual, they can also become completely obstructed.
