Small intestine blockage or small intestine obstruction is a serious medical condition that requires prompt medical care. The condition develops due to many factors and is associated with many illnesses. For example, the obstruction may occur due to mechanical reasons (hernia, tumor etc.) and it may also develop in a form of pseudo obstruction when there is no obvious physical obstruction but there is also no normal movement in the small intestine.What Are Causes of Small Intestine Blockage?

Small intestine blockage is medically known as ileus. The condition may develop due to many illnesses of the gastrointestinal tract. For example, hernia is one of the common causes of small intestine blockage. In such case the obstruction develops after the hernia traps the loop of the small intestine. Furthermore, similar effects may occur if one is suffering from an intestinal tumor. The tumor grows inside the affected part of the small intestine and once it becomes too large it simply interrupts the passage of the stool by completely blocking the inside of the intestine. People who have undergone an abdominal surgery are at risk of adhesions. Such fibrous tissue bands between different structures in the abdomen may be responsible for small intestine blockage.

Apart from the previously mentioned that accounts for approximately 90% of all cases of small intestine blockage the remnant 10% include blockage caused by twisting of the intestine (medically known as volvulus), inflammation and scarring associated with Crohn's disease, intussusception (invagination of one portion of the small intestine into another section of the intestine), chemical or electrolyte disturbances, intra-abdominal infection, kidney/lung disease and intake of certain medications or drugs.

Clinical Characteristics of Small Intestine Blockage

The condition is typically characterized by fever, loss of appetite, nausea and vomiting and in some cases diarrhea. One cannot pass stool or gas. There is swelling (bloating) of the abdomen and at one point abdominal muscles become way too rigid.

Treatment for Small Intestine Blockage

Depending on the underlying cause small intestine blockage treatment can be conservative or surgical. The cause and the precise location of the blockage can be confirmed with the assistance of abdominal X-ray or CT scan.

Non surgical treatment for obstruction is administered in a form of liquid or air through enemas and such patients are generally hospitalized. In case of mechanical obstruction one needs to be operated as soon as possible. This way doctors prevent intestinal perforation and all additional complications that may eventually result from the blockage. It may happen that the affected part of the intestine is surgically removed if there is a vascular damage and some of the tissues have become necrotic. No matter what the cause is the treatment must be prompt since intestinal blockage of any kind represents a medical emergency.
