摘要
目的:评价CT对闭合性腹部外伤所致胰腺损伤的临床诊断价值。方法:回顾性分析15例经手术证实的闭合性腹部外伤所致胰腺损伤的CT征象。结果:15例闭合性腹部外伤所致胰腺损伤中,胰腺挫伤5例,胰腺完全性断裂6例,胰腺不完全性断裂1例,胰腺出血3例。胰腺内出血、水肿,胰腺增粗是胰腺挫伤的直接征象;胰腺外形不连续、平扫或增强时垂直胰腺长轴的低密度、线条状影是胰腺断裂的直接征象。胰周积液、网膜囊积血积液,肾前筋膜增厚,腹腔积液是胰腺损伤的间接征象。结论:CT检查对胰腺损伤的诊断价值较大,CT增强比平扫更能明确胰腺的断裂;CT检查对于主胰管的断裂的诊断价值有待进一步研究。
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, hematoeele and effusion of omental bursa, prerenal fascia dtickening 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.
