  1. Management of Spleen/Liver Trauma George W. Holcomb, III, M.D., MBA Surgeon-in-Chief Children’s Mercy Hospital Kansas City, MO

  2. Mechanisms for Intra-abdominal Trauma • Motor vehicle collisions • Automobile vs pedestrian accidents • Falls • ATV • Handlebar injury from bicycle • Sports • Non-accidental trauma

  3. Frequency of Pediatric Blunt Abdominal Injuries • Spleen 27% • Kidney 27% • Liver 15% • Pancreas 2%

  4. Splenic Trauma • Diagnosis: • Plain abdominal film • Unreliable and nonspecific • Triad of radiographic findings in acute splenic rupture • Left diaphragmatic elevation • Left lower lobe atelectasis • Left pleural effusion Radiograph demonstrates a left pleural effusion, left basilar atelectasis, and inferomedial displacement of the splenic flexure (arrow)

  5. Splenic Trauma • Diagnosis: • FAST • Focused Abdominal Sonography for Trauma • Bedside study for unstable patient • 15% false-negative • May miss up to 25% of liver and spleen injuries • Compared to CT only 63% sensitive for detecting free fluid Fluid in the subphrenic space and splenorenal recess can be detected. The image shown demonstrates blood (arrow) between the spleen (S) and diaphragm (D).

  6. Splenic Trauma • Diagnosis: • CT with IV contrast • Noninvasive, highly accurate, easily identifies and quantifies extent of injury, for stable patient only A: Hemoperitoneum with a liver laceration (arrow) and a shattered spleen is seen.

  7. AAST Splenic Injury Scale *Advance one grade for multiple injuries, up to grade III Moore EE, Cogbill TH, Jurkovich GJ, et al

  8. AAST Splenic Injury Scale 17-yo boy injured on an ATV. Grade I injury with subcapsular fluid occupying less than 10% of spleen’s surface area.

  9. AAST Splenic Injury Scale 17-yo girl injured in an MVC. Grade II injury with laceration involving less than 3 cm of parenchymal depth

  10. AAST Splenic Injury Scale 18-yo boy injured playing football. Lacerations involving more than 3 cm of parenchymal depth radiating from splenic hilum -grade III laceration

  11. AAST Splenic Injury Scale 16-yo boy injured playing hockey. Fractured spleen involving more than 25%, Grade IV splenic laceration

  12. AAST Splenic Injury Scale 12-yo boy pedestrian struck by MV. Fractured spleen with hilar devascularization. Grade V injury.

  13. Splenic Trauma • Complications • Pseudoaneurysms • Often asymptomatic and resolve over time • If treatment required, angiographic embolization may be used • Also occur in liver trauma • Splenic pseudoaneurysm (arrowheads) after nonoperative treatment of blunt splenic injury. • Successful angiographic embolization The microcatheter used to deploy the coils is marked by the arrowheads and the embolic coils are marked by the arrows. 

  14. Splenic Trauma • Complications • Pseudocysts • Rare: 0.44% • May become large and painful • Tx: laparoscopic excision and marsupialization

  15. Splenic Trauma • Immunocompetence • Vaccination practices vary • Adult trauma evidence supports immunocompetence in healed grade IV injuries

  16. Splenic Trauma • If splenectomy is indicated • Pt requires vaccinations prior to discharge • Streptococcus pneumoniae • Pneumovax 23 • Haemophilus influenzae type B • Hib vaccine • Neisseria meningitidis • Quadravalent meningococcal/diphtheria conjugate • Prophylactic antibiotics controversial • Most centers use penicillin

  17. Splenic Trauma • Treatment • Nonoperative failure rate 2% • Risks for increased nonoperative failure rate • Bicycle-related injury mechanism • More than one solid organ injury • Peaks at 4 hrs, declines at 36hrs after admission

  18. Contrast Blush - Spleen Blunt Splenic Injury • 216 Pts – 7 yrs • 26 Pts – Contrast blush on CT scan • Lower HgB • More likely to need op (22% vs 4%) • Not a definite indication for operation, but indicates subset of pts who have active bleeding and may need transfusion and/or operation

  19. Liver Trauma • Blunt trauma is most common cause of injury to liver • High risk due to: • Large organ, friable parenchyma, ligamentous attachments

  20. AAST Liver Injury Grading Grade I Grade IV

  21. Types of Injury • Parenchymal damage/laceration • Subcapsular hematoma/contusion • Hepatic vascular disruption – contrast extravasation • Bile duct injury

  22. Diagnosis • Physical exam – • ±tachycardia, ±hypotention, peritoneal irritation • FAST – • better for unstable patients not stable enough for CT1 • CT w contrast • determine grade and look for active extravasation 1Coley et al. J Trauma 2000

  23. Contrast Blush - Liver • 105 pts – blunt liver injury – 6 yrs • 75 pts – Grade III – V • 22 pts – Contrast blush • transfusion req. • mortality (23% vs 4%) • ISS also • Mortality may be related to the other injuries

  24. Indication for Intervention • Operate for continued blood loss with hypotension, tachycardia, decreased urine output, decreasing Hg unresponsive to IVF and pRBC • Operative rates • 3-11% for multiple injuries • 0-3% for isolated liver injury • Angioembolization – not used as commonly as in adults

  25. Bile Duct Injury • With nonoperative management, 4% risk of persistent bile leak • HIDA with delayed images if bile duct injury suspected • ERCP with decompression and stenting – can be diagnostic and therapeutic

  26. 72 pts • 30 – Liver • 44 – Spleen • Liver vs spleen – • Longer recovery period • Nine complications • Greater use of resources J PediatrSurg 43:2264-2267, 2008

  27. APSA Guidelines APSA guidelines for hemodynamically stable children with isolated spleen or liver injury From Stylianos S, and APSA Trauma Committee: Evidence-based guidelines for resource utilization in children with isolated spleen or liver injury. J PediatrSurg 35:164-169, 2000

  28. Prospective study all pts with BSLI • No exclusions • Bedrest : Grade I – II inj – 1 night • Grade III – V inj – 2 nights J PediatrSurg 46:173-177, 2011

  29. Prospective Study - BSLI • 131 pts (spleen only 72, liver only 55 • 1 splenectomy (Grade V inj) • Transfusions – 24 (18 due to BSLI) • Mean injury grade – 2.6 • Mean bed rest – 1.6 days • Need for bed rest limiting factor in duration of hospital in 86 pts (66%) J PediatrSurg 46:173-177, 2011

  30. Prospective Study – BSLI An abbreviated protocol of 1 night for Grade I – II injuries and 2 nights for Grade III or higher in hemodynamically stable pts is safe and significantly decreases hospitalization c/w previous APSA recommendations.

  31. Solid Organ Injury • Treatment • > 90% of hemodynamically stable pts successfully managed non-operatively • Less than 10% require transfusion
