目的：探讨多层螺旋CT( MSCT)腹腔游离气体分布对上、下消化道穿孔的定位诊断价值。方法：分析54例消化道穿孔患者的MSCT资料，观察腹腔游离气体的分布特征，并与手术证实的穿孔部位进行对照分析。结果：上消化道穿孔患者MSCT腹腔游离气体在肝门、镰状韧带、圆韧带和胃十二指肠周围分布百分率均高于下消化道穿孔患者(P<0.05~P<0.01)，而下消化道穿孔患者腹腔游离气体在空回肠、肠系膜、阑尾和盆腔周围分布百分率均高于上消化道穿孔患者( P<0.05~P<0.01)。结论：MSCT图像上游离气体的分布有助于上、下消化道穿孔的鉴别，能够提高术前穿孔部位诊断的正确率。

Objective:To explore the value of the intraperitoneal free gas distribution of multislice CT(MSCT) in the positioning diagnosis of upper and lower gastrointestinal perforation. Methods:The distribution characteristics of intraperitoneal free gas in MSCT of 54 patients with gastrointestinal perforation were retrospectively analyzed, which was compared with surgical results. Results:The distribution proportions of MSCT intraperitoneal free gas in hepatic portal,falciform ligament,ligamentum teres hepatis and stomach and duodenum of the patients with upper gastrointestinal perforation were significantly higher than those of the patients with lower gastrointestinal perforation(P<0. 05 to P<0. 01). The distribution proportions of MSCT intraperitoneal free gas in jejunum and ileum, mesentery,appendix and pelvic cavity of the patients with upper gastrointestinal perforation were significantly lower than those of the patients with lower gastrointestinal perforation(P <0. 05 to P <0. 01). Conclusions:The distribution of the free gas in MSCT is conducive to identify the upper and lower gastrointestinal perforation,and can improve the diagnostic accuracy before operation.
