Post-traumatic pancreatico-dural fistula: Case report and management challenges()

Pancreatic injury can occur following high-energy blunt trauma to the torso. Although several types of pancreatic fistulas have been described in literature, we report to our knowledge, the first case of a pancreatico-dural fistula of traumatic origin. A 20-year-old male sustained a severe blow to the thoraco-abdominal region in the setting of a motorcycle accident. A total body scan revealed an AAST (American Association for the Surgery of Trauma) grade 4 splenic injury. A laparotomy with splenectomy and abdominal packing was performed. This was later followed by thoracolumbar instrumentation for posterior fixation of a T11–T12 transdiscal type C fracture with anterior subluxation of T11, according to the AO classification. Subsequent management was complicated by the persistence of a pseudomeningocele despite multiple surgical drainage procedures and a concomitant increase in retroperitoneal fluid collections. High levels of amylase and lipase in the pseudomeningocele fluid confirmed the presence of a pancreatico-dural fistula, due to a Wirsung duct rupture. This case report illiustrates the challenges in the management of this rare condition.
