ABSTRACT
BACKGROUND:
Bowel ultrasound (US) is one of the methods used to enhance diagnostic accuracy of necrotizing enterocolitis (NEC) and its associated complications in premature newborns.AIM:
To explore the diagnostic accuracy of BUS in extremely low birth weight (ELBW) infants with NEC.METHODS:
A single-center retrospective case-control study included 84 extremely low birth weight (ELBW) infants. The infants were divided into three groups Group 1 -infants with NEC (nâ=â26); Group 2 -infants with feeding problems (nâ=â28); Group 3 -control group (nâ=â30).RESULTS:
The specific BUS findings in premature newborns with NEC (stage 3) included bowel wall thinning, complex (echogenic) ascites, and pneumoperitoneum, pâ< â0.05. The diagnostic effectiveness of these sonographic signs was 96.8% (sensitivity 75.0% and specificity 97.6%), pâ< â0.05. These findings with high specificity were associated with the need for surgical intervention, poor outcomes, or increased mortality. Stage 2 NEC which did not require surgery showed impaired differentiation of the bowel wall layers, absent or decreased bowel peristalsis, pneumatosis intestinalis, portal venous gas, or simple ascites, with a diagnostic accuracy of 82.9% (sensitivity 55.6%, specificity 91.4%, pâ< â0.05).CONCLUSIONS:
BUS can be used as an adjunct to abdominal radiography to aid in the diagnosis of infants with suspected NEC by providing more detailed evaluation of the intestine.
