多层螺旋CT平扫对闭合性肠及肠系膜损伤的诊断

The diagnostic value of Multislice Spiral CT plain scan in bowel and mesenteric closed injury

目的分析闭合性肠及肠系膜损伤的多层螺旋CT表现特征,评价其对闭合性肠及肠系膜损伤的诊断价值。方法回顾性分析32例经手术证实的肠及肠系膜损伤患者的多层螺旋CT表现,分析病变部位、范围、形态、密度改变,并根据Janzen方法对病变严重程度分级。结果肠壁增厚25例;肠系膜区脂肪呈云雾状密度增高32例;肠系膜血肿24例;腹腔、腹膜后和肠间积液、积血28例;腹腔游离积气21例。结论肠及肠系膜损伤的CT表现有一定的特征性,是早期诊断闭合性肠及肠系膜损伤的重要手段。

Objective To study the characteristic of bowel and mesenteric closed injury by multisliee spiral computed tomography （MSCT）,and evaluate the value of MSCT in diagnosis for bowel and mesenterie closed injury. Methods All of 32 cases with bowel and mesenteric closed injury proved by surgery were analyzed retrospectively. All cases were analyzed the location, extent, form and density of the lesion, and the severity of lesion was graded according to Janzen methods. Results Twenty-five cases showed thickening bowel wall, 32 cases showed increased density in mesentery with cloudy shadow, 24 cases demonstrated mesenteric hematoma, free fluid and blood in the abdominal cavity or between the bowel was displayed in 28 cases, and free gas in the abdominal cavity was showed in 21 cases. Conclusion There are certain characteristic MSCT manifestations of bowel and mesentery trauma, and MSCT is an important method in diagnosis of bowel and mesenteric closed injury.
