Insights
Biliary rupture is a rare cause of jaundice in infants. Emergency physicians can use bedside ultrasound to diagnose this serious condition in young patients with abdominal distention.
Area of Science:
- Pediatric Emergency Medicine
- Abdominal Imaging
- Gastroenterology
Background:
- Jaundice in infants is infrequent in emergency departments.
- Biliary rupture is a rare and under-described cause of infant jaundice.
- Prompt diagnosis is crucial for favorable outcomes.
Observation:
- A 5-month-old male presented with jaundice, abdominal distention, and irritability.
- Bedside ultrasound revealed moderate ascites.
- Further imaging suggested a rupture of the common bile duct.
Findings:
- Surgical exploration confirmed common bile duct rupture.
- Choledocholithiasis was identified as the likely cause.
- This case highlights a rare pediatric surgical emergency.
Implications:
- Emergency physicians should consider biliary rupture in infants with unexplained jaundice and abdominal distention.
- Bedside ultrasound is a valuable tool for initial assessment in the emergency department.
- Early recognition and intervention are critical for managing this rare condition.
Background:
Jaundiced infants are uncommon in most emergency departments (EDs). Biliary rupture remains one of the more rare and less described causes of this condition.
Case Report:
A 5-month-old male presented to our ED with scleral icterus, increasing abdominal distention, and increased irritability. A bedside ultrasound revealed a moderate amount of ascites and further imaging suggested he had a rupture of his common bile duct. Surgical exploration confirmed this and revealed the presence of choledocholithiasis, which was the likely cause of the rupture. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Biliary rupture remains a rare but serious condition in very young patients. Emergency physicians should consider bedside ultrasound as an adjunct in undifferentiated abdominal distention or jaundice in this patient population.
