Abstract

Abstract: Introduction: This review acquaints neonatal clinicians using point‐of‐care ultrasound with a range of pathological bowel ultrasound findings, with the aim to promote utility of this skill as a diagnostic assessment tool in diseased neonatal intestinal states. Overview: A range of normal and pathological bowel ultrasound findings are illustrated with case examples from our neonatal intensive care unit. The technical challenges of lack of familiarity with sonographic appearance of bowel (healthy and diseased), occurrence of gas artefacts and requirements of high‐resolution linear transducer probes are described to allow the development of skills amongst neonatologists trained in point‐of‐care ultrasound. Plain abdominal radiography continues to remain the standard investigation to differentiate benign bowel states such as continuous positive airway pressure (CPAP) belly syndrome in preterm infants from life‐threatening pathological intestinal states such as necrotising enterocolitis. Although plain radiography is the gold standard modality in the evaluation of neonatal diseased bowel states, real‐time point‐of‐care bowel ultrasound performed in conjunction can provide valuable information on bowel peristalsis, bowel wall thickness and bowel vascularity. Abnormal configuration of superior mesenteric vessels on colour Doppler can alert the clinician to the diagnosis of neonatal intestinal malrotation‐a time critical emergency. Conclusion: Further research is needed to explore true‐negative and true‐positive predictive values of bowel ultrasound. However, with expansion of knowledge, appropriate training of techniques, neonatologists will be able to enhance their diagnostic acumen by performing point‐of‐care bowel ultrasound in conjunction with plain radiography in the evaluation of broad array of neonatal intestinal states.
