Insights
Blunt abdominal trauma rarely causes bile duct injury. This case highlights endoscopic retrograde biliary drainage as a successful minimally invasive treatment for isolated pediatric bile duct stricture following trauma.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Trauma Surgery
Background:
- Bile duct injury (BDI) from blunt abdominal trauma is uncommon.
- BDIs typically occur with significant liver parenchymal damage.
- Isolated common bile duct strictures post-trauma are exceptionally rare in pediatric patients.
Observation:
- A 15-year-old male presented with jaundice.
- The jaundice was caused by an isolated common bile duct stricture.
- There was no associated liver injury.
Findings:
- Endoscopic retrograde biliary drainage (ERBD) was successfully performed.
- Jaundice resolved within 2 months of initiating ERBD.
- Despite restenosis and mild jaundice at 2-year follow-up, ERBD proved effective.
Implications:
- ERBD can be a primary, minimally invasive treatment option for pediatric posttraumatic biliary strictures.
- This approach may avoid more invasive surgical interventions.
- Further research into long-term outcomes of ERBD for pediatric biliary trauma is warranted.
Abstract:
Bile duct injury caused by blunt abdominal trauma is rare and usually associated with liver parenchymal injury. The authors report the case of a 15-year-old boy with jaundice caused by a posttraumatic isolated common bile duct stricture without associated liver injury. Endoscopic retrograde biliary drainage (ERBD) was performed and the jaundice disappeared 2 months after drainage commenced. Although restenosis and mild jaundice was revealed 2 years after injury, ERBD can be a first-line minimally invasive treatment of pediatric posttraumatic biliary stricture.
