NECDefinition Return to top
Necrotizing enterocolitis is an acquired disease, primarily in premature infants or sick newborns, in which intestinal tissue dies.Causes, incidence, and risk factors Return to top
In necrotizing enterocolitis, the lining of the intestinal wall dies and the tissue sloughs off. The cause for this disorder is unknown, but it is thought that a decreased blood flow to the bowel keeps the bowel from producing the normal protective mucus. Bacteria in the intestine may also be a causative factor.
At risk are small, premature infants, infants who are fed concentrated formulas, infants in a nursery where an outbreak has occured (suggesting an infectious cause), and infants who have received blood exchange transfusions.

Treatment Return to top
In an infant suspected of having necrotizing enterocolitis, feedings are stopped and the bowel is decompressed of gas by inserting a small tube into the stomach. Intravenous fluid replaces formula or breast milk. Antibiotic therapy is started. The infant's condition is monitored with abdominal x-rays, blood tests, and blood gases.Expectations (prognosis) Return to top
Necrotizing enterocolitis is a serious disease with a death rate approaching 25%. The outcome is improved by aggressive, early treatment.Complications Return to top
Calling your health care provider Return to top
This disorder usually develops in an infant that is already ill or premature, and most often develops while the infant is still in the hospital. If any symptoms of necrotizing enterocolitis develop, especially in an infant that has recently been hospitalized for illness or prematurity, go to the emergency room or call the local emergency number (such as 911).
