Usefulness of Endoscopic Retrograde Cholangiopancreatography in the Diagnosis and Treatment of Traumatic Pancreatic Injury in Children

Pediatric trauma patients are increasing, and trauma is the leading cause of death in children. Pancreatic injury is known as the fourth most common solid organ injury, but the diagnosis of pancreatic injury is often delayed due to the retroperitoneal location of the pancreas and the low sensitivity and specificity of diagnostic tests. Endoscopic retrograde cholangiopancreatography (ERCP) is an important test for the diagnosis and treatment of various biliary tract and pancreatic diseases. However, cases of performing ERCP in traumatic pancreatic injury in children have been rarely reported. Thus, we aimed to evaluate the usefulness of ERCP in traumatic pancreatic injury in children. Between January 1983 and December 2022, pediatric patients under the age of 18 who were treated for traumatic pancreatic injury at a single institution were recruited and retrospectively analyzed. Patient characteristics and clinical outcomes were assessed. Thirty-one patients were enrolled in this study. Among them, 15 (48.4%) patients underwent ERCP. The time to diet was significantly longer in the ERCP group. There were no statistically significant differences in other characteristics between the ERCP and the non-ERCP group. In nine (60%) patients of the ERCP group, ERCP was used for therapeutic intervention or as a decision-making tool for surgery, and was used to resolve pancreas-related complications. ERCP may be useful for the diagnosis and treatment of traumatic pancreatic injury in children. In addition, ERCP can be safely applied in children, and complications related to ERCP also may not increase. When obscure pancreatic injury is suspected, it is necessary to consider performing ERCP.
