Penetrating injuries occur in 10% of pediatric trauma patients with injuries isolated to the pancreas in low velocity situations such as stab wounds and impalements. Injuries to the pancreas secondary to gunshot wounds often involve multiple systems, and the pancreas should be evaluated during operative exploration for penetrating injuries. The majority of pancreatic injuries in children occur after blunt trauma with handlebar injuries being the most common cause. 1 Child abuse, pedestrian struck, motor vehicle collision, and fall are other causes of pancreatic trauma with equivalent rates (10-20%). In a review comparing pancreatic injuries in children to adults, kids have a higher rate of injury secondary to bicycle accidents, are more likely to have isolated injuries, and have lower grade injuries than adults. 2
DiagnosisThe diagnosis of pancreatic injuries can be very difficult and usually starts with a high index of suspicion based on mechanism. A complete history and physical examination can be helpful, but physical examination findings are rare from most pancreatic injuries secondary to the retroperitoneal location of the pancreas and the higher frequency of isolated injuries in children. Laboratory values are often obtained though their significance in diagnosing and grading injury is questionable. Amylase and lipase are often used as a screening tool in patients with blunt abdominal trauma, though the sensitivity was only 84% in one study with a low positive predictive value related to the low prevalence of disease. 3 Another multicenter review revealed no correlation with grade of injury, length of stay, or mortality, 4 though one study did show a correlation of peak amylase level and major pancreatic injuries. 5 A variety of imaging modalities are available for evaluating the pancreas for injury. Computed tomography (CT) is often utilized for the workup of patients with abdominal trauma though historical studies reported low sensitivity and specificity for diagnosing pancreatic injury. 6 More recent studies examining multidetector CT have shown improved sensitivity and specificity for detecting pancreatic injury, though a multicenter study sponsored by the American Association for Trauma reported low sensitivity and high specificity for identifying pancreatic ductal injuries. 7,8 Additional imaging with magnetic resonance and endoscopic retrograde cholangiopancreatography are often used when ductal anatomy is difficult to ascertain. Studies evaluating the use of magnetic resonance imaging report favorable results, though the Keywords ► pancreatic injuries ► duodenal injuries ► blunt trauma ► pediatric Abstract Trauma is the leading cause of death in children of all ages. The most common site of injury in pediatric patients is the head followed by the extremities and the abdomen. Though less than 10% of admissions to the hospital are secondary to intra-abdominal injuries, mortality related to these injuries is not insignificant. Pancreatic and duodenal trauma occurs in 3 to 12% of the patients with abdom...
