Successful treatment for necrotizing enterocolitis in premature infants occurs in approximately 70% of cases without surgery.

It begins in infants shortly after birth

Necrotizing enterocolitis is the most common cause of death in newborns undergoing surgery. The average mortality is 30-40%, even higher in severe cases.

In very small or sick premature infants, the risk for necrotizing enterocolitis may be diminished by beginning parenteral nutrition and delaying enteral feedings for several days to weeks.

NEC in this context means necrotizing enterocolitis.
