目的:探讨胰腺撕裂伤的CT表现。方法:搜集18例经临床手术证实的胰腺撕裂伤病例资料,分析其CT平扫及增强表现。普通CT扫描层厚5mm,螺旋CT均行薄层多平面重组(MPR)。结果:胰腺内血肿3例,胰腺局限或弥漫性肿胀11例,网膜囊积液12例,胰周积液及左侧肾前筋膜增厚18例,平扫9例胰腺实质内可见低密度撕裂口,增强扫描所有病例胰腺实质内均可见低密度撕裂伤口,其中胰头5例,胰颈8例,胰腺体尾部5例。主胰管损伤CT诊断符合率70%。合并其他脏器损伤12例。结论:胰腺撕裂伤有较特征性的CT表现,CT薄层增强扫描可准确诊断胰腺撕裂伤。CT对主胰管损伤的判断有一定的限度。
Objective: To investigate CT findings of pancreatic laceration. Methods: Data of 18 cases of pancreatic laceration confirmed by clinical operation were collected and their CT scan and enhancement were analyzed. Common CT scan thickness 5mm, spiral CT thin layer multiplanar reconstruction (MPR). Results: 3 cases of pancreatic hematoma, pancreatic localized or diffuse swelling in 11 cases, 12 cases of omental effusion, peripancreatic fluid and left anterior fascia in 18 cases of thickening, 9 cases of pancreatic parenchyma visible low Density tear mouth, enhanced scan all cases of pancreatic parenchyma were seen low-density laceration wound, including 5 cases of pancreatic head, pancreatic neck in 8 cases, 5 cases of pancreatic body tail. The diagnosis of primary pancreatic duct injury coincidence rate of 70%. Combined with other organ injury in 12 cases. CONCLUSION: Pancreatic laceration has more characteristic CT findings. CT thin-section enhanced scanning can accurately diagnose pancreatic laceration. CT on the diagnosis of pancreatic duct injury to a certain extent.
