Necrotizing Enterocolitis Overview
Learn About Necrotizing Enterocolitis
Necrotizing enterocolitis (NEC) is the death of tissue in the intestine. It occurs most often in premature or sick babies.
NEC occurs when the lining of the intestinal wall dies. This problem nearly always develops in an infant who is ill or premature. It is likely to occur while the infant is still in the hospital.
The exact cause of this disorder is unknown. A drop in blood flow to the bowel can damage the tissue. Bacteria in the intestine may also add to the problem. Also, premature infants have an undeveloped immune response to factors such as bacteria or low blood flow. An imbalance in immune regulation appears to be involved in NEC.
Babies at higher risk for the condition include:
- Premature infants
- Infants who are fed formula rather than human milk. (Human milk contains growth factors, antibodies and immune cells which may help prevent the problem.)
- Infants in a nursery where an outbreak has occurred
- Infants who have received blood exchange transfusions or have been seriously ill
Symptoms may come on slowly or suddenly, and may include:
- Abdominal bloating
- Blood in the stool
- Diarrhea
- Feeding problems
- Lack of energy
- Unstable body temperature
- Unstable breathing, heart rate, or blood pressure
- Vomiting
Treatment for a baby who may have NEC most often includes:
- Halting enteral (GI tract) feedings
- Relieving gas in the bowel by inserting a tube in the stomach
- Giving IV fluids and nutrition
- Giving IV antibiotics
- Monitoring the condition with abdominal x-rays, blood tests, and measurement of blood gases
The infant will need surgery if there is a hole in the intestines or inflammation of the abdominal wall (peritonitis).
In this surgery, the doctor will:
- Remove dead bowel tissue
- Perform a colostomy or ileostomy
The bowel may be reconnected after several weeks or months when the infection has healed.

Necrotizing enterocolitis is a serious disease. Up to 40% of infants with NEC die from it. Early, aggressive treatment can help improve the outcome.
Complications may include:
- Peritonitis
- Sepsis
- Intestinal perforation
- Intestinal stricture
- Liver problems from prolonged inability to tolerate enteral feeds and need for parenteral (IV) nutrition
- Short bowel syndrome if a large amount of intestine is lost
Get emergency medical care if any symptoms of necrotizing enterocolitis develop. Infants who are hospitalized for illness or prematurity are at higher risk for NEC. They are watched closely for this problem before they are sent home.
Summary: The goal of the NANO trial is to study the longstanding clinical practice of empirically administering intravenous antibiotics to extremely low birthweight (ELBW) infants in the first days of life. In this 802-subject multicenter placebo-controlled randomized clinical trial, the hypothesis to be tested is that the incidence of adverse outcomes is higher in babies receiving empiric antibiotics (EA)...
Summary: Necrotizing enterocolitis (NEC) is a devastating disease that affects the intestine of premature infants and is the most common surgical emergency in newborns. It is estimated that up to 10% of premature babies can suffer from this condition. Despite aggressive medical treatment, surgical intervention is necessary in up half of the cases for bowel necrosis or perforation and these often represent ...
