Is Pneumatosis a NEC?
Is Pneumatosis a NEC?
Pneumatosis intestinalis is a radiologic sign pathognomonic of necrotizing enterocolitis (NEC). It appears as a characteristic train-track lucency configuration within the bowel wall.
What is pneumatosis intestinalis?
Pneumatosis intestinalis (PI) refers to the presence of gas within the wall of the small or large intestine. Intramural gas can also affect the stomach, but this condition is referred to as gastric pneumatosis [1].
How common is necrotizing enterocolitis?
It affects 1 in 1,000 premature babies. The risk is greatest for babies weighing less than 2 pounds. The condition only rarely affects full-term infants. About 1 in 10,000 full-term babies get NEC.
What does pneumatosis intestinalis look like?
The patterns of the radiolucencies are seen as linear, curvilinear, small bubbles, or collections of cysts. Cystic collections of gas localized to the wall of the colon are suggestive of primary pneumatosis intestinalis.
What are the most common complications of enterocolitis?
[2] [4] The 2 most common complications are intestinal stricture and short gut syndrome. Intestinal stricture occurs when an area of the intestine heals with scarring that impinges on the inside of the bowel. It is most common in infants treated without surgery.
What are the signs and symptoms of NEC?
Signs and symptoms may include abdominal distension, bloody stools, vomiting bile-stained fluid, and pneumatosis intestinalis (gas in the bowel wall) identified on abdominal x-ray. Affected infants occasionally have temperature instability, lethargy, or other findings of sepsis. [1] [2] The exact cause of NEC is unknown.
What are the risks of recurrent NEC ( NEC )?
Recurrent NEC is an uncommon complication (occurring in about 4-6%), but it can occur after either operative or nonoperative management of NEC. Infants who survive NEC are also at increased risk for neurodevelopmental problems; however, these problems may result from underlying prematurity rather than from NEC. [2]
Which is the most serious post-operative complication in NEC?
Short gut syndrome is the most serious post-operative complication in NEC, occurring in as many as 23% after resection. It is a malabsorption syndrome resulting from removing excessive or critical portions of the small bowel. [2]
