Management of traumatic pancreatic pseudocysts in children.

Eight children with pancreatic injuries after blunt abdominal trauma are presented. One patient with pancreatitis without complications was treated successfully with medication; seven (87.5%) developed pseudocysts, which resolved spontaneously with conservative treatment in four cases (57.1%). Non-resolving pseudocysts in 3 patients finally required surgical intervention. Pseudocysts that resolve spontaneously and those that require surgical intervention can be distinguished. The two groups showed different time sequences in both serum amylase values and pseudocyst size. Analyses of these clinical data revealed three factors with significant predictive value. On the basis of these findings, a new management strategy for traumatic pancreatic pseudocysts in children is proposed. The cyst is likely to resolve spontaneously in cases showing any two or more of the following factors: (1) cyst presentation after day 6; (2) maximum serum amylase below 1,600 IU/l; and (3) serum amylase below 600 IU/l on day 20. However, early surgical intervention is required in the presence of two or more of the following: (1) cyst presentation before day 4; (2) maximum serum amylase above 1,900 IU/l; or (3) serum amylase above 1,200 IU/l on day 20.
