CT diagnosis of pancreatic injury induced by blunt abdominal trauma(analysis of 15 cases)

Objective:To evaluate the clinical value of CT by analyzing the CT manifestations of the pancreatic injury induced by blunt abdominal trauma.Methods:The CT findings of 15 patients with surgical proved pancreatic injury induced by blunt abdominal trauma were reviewed retrospectively.Results:In our 15 patients, there were 5 patients with pancreatic contusion,6 cases with pancreas broken completely,1 case with pancrease broken incompletely and 3 cases with hemorrhage were also found.The direct CT signs of pancreatic contusion were hemorrhage,edema and thickening of pancreas;and the broken of pancreas shape,lower density line across the pancreas vertically on pre-and post-CT imaging were the direct signs of pancreas broken.The indirect CT signs of pancreatic contusion included peripancreatic effusion,hematocele and effusion of omental bursa,prerenal fascia thickening and effusion of abdominal cavity.Conclusion:The diagnostic value of the CT imaging is demonstrated for pancreatic injury,and broken pancreatic could be confirmed with contrast-enhanced CT better than non-enhanced CT.There is no diagnostic value with CT to make sure whether main pancreatic duct broken or not.
