Point-of-Care Ultrasound in Acute Neonatal Ascites.

We present a 4-week-old neonate with acute onset of bloody stools and abdominal distention. Point-of-care ultrasound performed in the emergency department allowed for rapid diagnosis of a large amount of free intra-abdominal fluid, which together with the physical findings, prompted emergent operative exploration revealing chylous ascites. Although no areas of active volvulus were identified intraoperatively, findings in the case were suggestive of small bowel volvulus and deemed as the most likely etiology for this patient's presentation. In this report, we review the relevant aspects of ultrasonography for ascites and discuss the diagnosis of chylous ascites.
