Imaging of acute abdominal emergencies in infants and children

Neonatal Gastrointestinal Emergencies: A Radiological Review

BACKGROUND

Abdominal emergencies in neonates require surgical management in almost all cases and complications may include bowel perforation, sepsis, shock, and even death. Radiological imaging has become a very important aid in the clinical setting as it shortens time to diagnosis.

OBJECTIVE

The objective of this review is to discuss the more prevalent neonatal gastrointestinal emergencies, review appropriate imaging options, and illustrate common radiological presentations of these entities.

CONCLUSION

Despite advancements in imaging techniques, it is important to keep in mind that neonates have a higher susceptibility to the adverse effects of ionizing radiation, and therefore radiography and ultrasonography remain the main diagnostic modalities for ruling out the diseases with the worst prognosis. Other modalities (fluoroscopy, computed tomography, and magnetic resonance imaging) may have limited use in very specific conditions. All providers in an emergency department should be familiar with the basic radiological findings that may indicate a gastrointestinal emergency, especially in health institutions that do not have 24-h radiologist coverage.

Sonography of acute appendicitis and its mimics in children

The diagnosis of acute right lower quadrant pain in a pediatric population is challenging. Acute appendicitis is the most common cause of an acute surgical abdomen. The common mimics of acute appendicitis are acute gastrointestinal and gynecologic diseases. This article reviews the sonographic findings of the spectrum of common acute abdominal emergencies in children with a focus on imaging clues to a specific diagnosis. This awareness can impact on diagnostic accuracy and impact patient management.

Understanding neonatal bowel obstruction: building knowledge to advance practice

Providing care to neonates with bowel obstruction requires a basic understanding of gastrointestinal (GI) anatomy and functional landmarks as well as knowledge of the pathophysiology associated with intestinal blockage. Early recognition and prompt diagnosis necessitate astute assessment of common presenting symptoms and accurate interpretation of diagnostic investigations. Initial medical management is focused primarily on gastric decompression and maintenance of fluid and electrolyte balance. This article describes features of the neonatal GI tract and discusses common causes of neonatal bowel obstruction.
