目的探讨腹部外伤致急性闭合性胰腺损伤的CT诊断及临床实用价值。方法回顾性分析21例经手术证实的胰腺损伤CT表现特点。结果胰腺损伤21例,其中胰腺局部或弥漫性增大9例,胰腺实质内斑片状低密区2例,斑点或斑片状高密度影5例,胰腺周围渗出、积液7例,肾前筋膜增厚5例,2例表现为胰腺局部增大密度轻微减低而漏诊,24 h后行增强CT复查,见局部密度不均匀减低,胰腺撕裂伤7例。结论 CT检查对于胰腺损伤是一种很有效的检查方法 ,CT平扫可显示胰腺的肿胀、出血,对胰腺断裂的显示,可行CT薄扫及增强扫描,可提高检出率。
Objective To investigate the CT diagnosis and clinical value of acute closed pancreas injury caused by abdominal trauma. Methods The CT features of 21 cases with confirmed pancreatic injury were retrospectively analyzed. Results There were 21 cases of pancreatic injury, including 9 cases of local or diffuse pancreatic enlargement, 2 cases of low-density plaque in the parenchyma of the pancreas, 5 cases of speckled or patchy high- Five cases of prerenal fascia thickening, 2 cases showed a slight decrease in the local increased density of the pancreas and missed diagnosis, 24 h after enhanced CT review, see the uneven reduction in local density, pancreatic laceration in 7 cases. Conclusion CT scan is a very effective method for the diagnosis of pancreatic injury. CT scan shows the swelling and hemorrhage of the pancreas, the display of pancreatic rupture, and the thin CT scanning and enhanced scanning. It can improve the detection rate.
