Traumatic Pancreatic Injury
in paediatric patientsJoint Hospital Surgical Grand
Round Oct 2013Dr WB Wong Tuen Mun Hospital
Epidemiology
4th most common solid organ injury following spleen, liver and kidneys
3 to 12% of all trauma admissions Causes: Bicycle handlebar Motor vehicle accident Horse kicking Penetrating injuries
http://www.cobywootenlaw.com/bicycle-accidents/
Diagnosis History, physical examination, X-ray Serum markers Contrast CT scan ERCP and MRCP Exploratory laparotomy Suspected associated injuries Hypotension Peritonitis
Use of CT
Associated injuries Uncertain sensitivity for ductal
injuries Features of ductal injury: 50% laceration through the gland Complete gland transection Presence of early peripancreatic fluid
collection
ERCP and MRCP
ERCP Diagnose ductal injury Pancreatic stent Difficult procedure in paediatric patients Risk of procedure
MRCP Non-invasive Use of secretin
Surgical exploration
Indicator of ductal injuries: Direct visualizaion of injury Complete transection of
gland Laceration of greater than
½ of gland Central perforation Severe maceration http://www.trauma.org/index.php/main/image/

American Assoication for the Surgery of Trauma Classification
Pancreas Injury ScaleGrade Type of Injury Description of Injury I Hematoma Minor contusion without duct injury Laceration Superficial laceration without duct injury
II Hematoma Major contusion without duct injury or tissue loss Laceration Major laceration without duct injury or tissue loss
III Laceration Distal transection or parenchymal injury with duct involvement
IV Laceration Proximal transection or parenchymal injury involving ampulla
V Laceration Massive disruption of pancreatic head
*Advance one grade for multiple injuries up to grade III
Management
Conservative management for Grade I and II
Operative management for ductal injuries
Grade III: Distal pancreatectomy +/- spleen preservation
Grade IV: Pancreaticojejunostomy Grade V: Pancreaticoduodenectomy
Paediatric patients Trivial injury Delayed presentation Isolated injury Low mortality Operative morbidity Incidental splenectomy Bowel obstruction Abscess Fistula

Modifed LUCAS Classification
Class I Simple superficial contusion or peripheral laceration with minimal parenchymal damage, any portion of the pancreas can be affected, but intact main pancreatic duct
Class II Deep laceration, perforation or transection of the neck, body or tail of the pancreas, with or without pancreatic duct injury
Class III Severe crush, perforation or transection of the head of the pancreas, with or without pancreatic duct injury
Class IV Combined pancreaticoduodenal injuries
(a) Minor pancreatic injury
(b) Severe pancreatic and also duct injury
Classification by Smego
Grade I Contusion/ haematoma, intact capsule, no parenchymal injury
Grade II Parenchymal injury without major duct injury
Grade III Parenchymal disruption, presumed major ductal injury
Grade IV Massive parenchymal disruption
