Although many premature infants may survive NEC, the disease can cause long-term problems.
Long-term effects of NEC (Necrotizing Enterocolitis) may include, but are not limited to:
Intestinal strictures
Intestinal strictures are the narrowing of the intestine, which can lead to a blockage.
This may require surgery to open up the intestine.
Other long-term gastrointestinal complications include adhesion, which is when the intestines stick to each other, and fistulas, which are abnormal connections between different parts of the intestine.
Developmental delays
NEC can cause developmental delays, both physical and cognitive.
Physical developmental delays may include problems with movement and coordination.
For example, an infant may have difficulty sitting up or crawling.
Cognitive developmental delays may include problems with learning, thinking, and problem-solving.
Feeding difficulties
NEC can also cause feeding difficulties.
An infant may have trouble sucking or swallowing, which can make it difficult to eat by mouth.
They may need to be fed through a tube that goes through the nose and into the stomach (nasogastric tube) or directly into the stomach through a surgical opening (gastrostomy).
Organ damage
As mentioned previously, NEC can cause organ damage, particularly to the intestines.
In severe cases, NEC may even lead to death.
Even with treatment, some infants may have long-term gastrointestinal problems or need lifelong assistance with feeding due to organ failures.
Growth problems
NEC can stunt a child’s growth.
Children who survive NEC are often smaller than their peers.
They may also have problems gaining weight and growing at a normal rate.
Malabsorption
Malabsorption is when the intestine cannot absorb enough nutrients from food.
This can cause poor growth, diarrhoea, and weight loss and is more common in premature infants who have had a part of their intestine removed.
Short bowel syndrome
Short bowel syndrome is when the intestine is too short to function properly.
This can be caused by surgery to remove a section of the intestine.
Short bowel syndrome can sometimes lead to malnutrition, dehydration, and weight loss.
