MSCT在闭合性十二指肠损伤诊断的价值

Value of multislice CT in the diagnosis of closed duodenal injury

目的探讨MSCT在闭合性十二指肠损伤诊断中的应用价值。方法回顾性分析我院2006年1月～2012年10月经手术证实的13例闭合性十二指肠损伤病例的CT以及临床资料。结果11例见腹膜后和腹腔游离气体。8例CT增强扫描有5例（62.5％），5次观察到十二指肠肠壁破裂的破口及内容物外溢。13例均表现为十二指肠肠壁不同程度增厚，部分肠壁边缘模糊。13例均有腹腔、腹膜后积液及右侧肾周模糊、积液。4例肠系膜根部脂肪密度增高伴少许血肿形成。结论闭合性十二指肠损伤具有一定特征性的CT征象，CT薄层扫描、多平面重组及增强扫描能有效检查出闭合性十二指肠损伤，为临床诊断及治疗提供重要依据。

Objective To study the muhislice CT appearance of closed duodenal injury. Methods The CT of 13 patients with closed duodenal injury were retrospectively analyzed. Results CT findings included peritoneal, retroperitoneal and right perirenal fluid （13）, duodenal wall thickening （13）, free air in the celiac and retroperitoneal regions （11）, duodenal perforation （5）, mesenteric fat stranding and hematoma （4）. Conclusions Contrast-enhanced multislice CT with muhiplanar reconstruction provides valuable information for diagnosis of closed duodenal injury.
