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 bowel US 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 (n = 26); Group 2 -infants with feeding problems (n = 28); Group 3 -control group (n = 30).

Results: The specific bowel US findings in premature newborns with NEC (stage 3) included bowel wall thinning, complex (echogenic) ascites, and pneumoperitoneum, p < 0.05. The diagnostic effectiveness of these sonographic signs was 96.8% (sensitivity 75.0% and specificity 97.6%), p < 0.05. 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%, p < 0.05).

Conclusions: Bowel US 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.

肠道超声诊断极低出生体重儿坏死性小肠结肠炎的效果。

背景：肠道超声（US）是用于提高早产新生儿坏死性小肠结肠炎（NEC）及其相关并发症诊断准确性的方法之一：方法：一项单中心回顾性病例对照研究纳入了 84 名极低出生体重（ELBW）婴儿。这些婴儿被分为三组：第一组：NEC患儿（26人）；第二组：喂养问题患儿（28人）；第三组：对照组（30人）：早产新生儿 NEC（第 3 期）的 BUS 特殊发现包括肠壁变薄、复杂（回声性）腹水和腹腔积气，P < 0.05。这些超声征象的诊断有效率为 96.8%（敏感性 75.0%，特异性 97.6%），P < 0.05。这些特异性较高的结果与手术干预需求、不良预后或死亡率增加有关。无需手术的 NEC 2 期表现为肠壁层分化受损、肠蠕动消失或减弱、肠道积气、门静脉气体或单纯腹水，诊断准确率为 82.9%（敏感性 55.6%，特异性 91.4%，P < 0.05）：BUS可作为腹部放射摄影的辅助手段，通过对肠道进行更详细的评估来帮助诊断疑似NEC婴儿。
