多层螺旋CT扫描在急腹症胃肠道穿孔中的应用价值
摘 要 目的:探讨多层螺旋CT(MSCT)扫描在急腹症胃肠道穿孔中的应用价值。方法:对30例经手术证实的胃肠道穿孔患者的临床资料和影像学表现进行回顾性分析。结果:X线平片诊断胃肠道穿孔23例,诊断率为76.67%,表现为膈下游离气体。MSCT扫描诊断胃肠道穿孔30例,诊断率为100.00%,其中有16例为十二指肠球部前壁胃穿孔,8例为胃小弯前壁穿孔,6例为胃窦前壁穿孔,表现为腹腔内游离气体。结论:与X线平片检查相比较,MSCT扫描能更早、更准确地诊断胃肠道穿孔,并能为其定位和病因提供重要的诊断依据。

ABSTRACT Objective: To evaluate the application value of multi-slice spiral CT in acute abdomen with gastrointestinal perforation. Methods: The clinical data and imaging findings from 30 patients with gastrointestinal perforation confirmed by surgery were retrospectively analyzed. Results: Twenty-three cases were diagnosed as gastrointestinal perforation by X-ray plain film with diagnosis rate of 76.67% and appeared as the lower reaches of the gas from the diaphragm while 30 cases by multi-slice spiral CT scanning with diagnosis rate of 100%, in which there were 16 cases of patients with duodenal anterior wall of gastric perforation, 8 cases with gastric perforation and 6 cases with gastric sinus perforation. Conclusion: Compared with X-ray examination, multi-slice spiral CT scanning can early and accurately diagnose gastrointestinal perforation, and can provide important diagnostic basis for its location and etiology.

胃肠道穿孔是临床比较常见的一种急腹症,由于其发病快,病情进展迅速,临床上采取及时而有效的诊断方法就显得尤为重要。影像学检查对于诊断该病具有重要作用,但是部分患者因为穿孔部位太小,只有少量游离气体,在进行X线和超声检查时往往难以显示而呈假阴性,导致漏诊,而多层螺旋CT(MSCT)对腹腔内少量游离气体也具有很高的敏感性。CT判断穿孔部位主要依赖于阶段性肠壁增厚、局灶性肠壁缺损或邻近肠壁的游离气体[1]。MSCT 的出现为胃肠道穿孔提供了更精细、更准确和更全面的影像学检查手段,已成为胃肠道穿孔诊断最基本、最有效的影像学检查方法[2]。本文对30例经外科手术证实的胃肠道穿孔患者进行回顾性分析,观察其 MSCT 表现特征,旨在探讨 MSCT 在胃肠道穿孔中的临床应用价值,现将结果报道如下。
