Point-of-care Ultrasound to Diagnose and Monitor the Course of Necrotizing Enterocolitis

Abstract

Context:

Neonatal gut ultrasound (US) is an emerging clinical tool for quick diagnosis and prognosis in various abdominal pathologies. In this review, we summarize normal gut US findings and concentrate on the specifications of diagnosing necrotizing enterocolitis.

Evidence:

A comprehensive literature search was conducted across numerous sources with relevant keywords along with the specified age group of 0–28 days of life.

Findings:

This review describes the normal gut US picture with the basic technicalities needed to master the art of point-of-care (POC) abdominal US. This modality is gaining importance due to its accuracy, applicability, safety, and affordability. Key findings include altered bowel perfusion, decreased peristalsis, and bowel wall thickening with better precision compared to abdominal X-ray (AXR). Many meta-analyses and narrative reviews have already demonstrated their usefulness. The high specificity and positive predictive value could make this tool a guide for early identification and prompt surgical intervention in the dreaded diagnosis of necrotizing enterocolitis.

Conclusion:

Emerging evidence and expertise in the field of abdominal US will make it a valuable tool for early diagnosis and prognosis of necrotizing enterocolitis.
