非创伤性下消化道穿孔的急诊影像学分析

To Explore the Emergency Image of Non Traumatic Lowe Digestive Tract Perforation

目的分析非创伤性下消化道穿孔的急诊影像学资料。方法回顾与分析60例经手术证实为下消化道穿孔患者的急诊影像学资料,分析腹部超声、MSCT以及立位腹部平片在下消化道穿孔诊断中的准确性。结果本组60例患者中,术前采取腹部超声检查38例,存在膈下游离气体9例,确诊消化道穿孔。术前采取立位腹部平片检查30例,存在膈下游离气体8例,确诊消化道穿孔。术前采取MSCT检查11例,腹腔发现游离气体10例,其中明确穿孔部位9例。增强扫描诊断下消化道穿孔所造成的腹腔游离气体的准确性优于立位腹部平片、腹部超声,P<0.05,差异具有统计学意义。结论对于下消化道穿孔患者采取腹部MSCT扫描,能及时发现下消化道穿孔所造成的腹腔游离气体。

Objective To Analysis the emergency image data of non-traumatic lower gastrointestinal perforation. Methods Retrospective analysis 60 patients with gastrointestinal perforation emergency imaging data confirmed by surgery, to explore the MSCT and orthostatic KUB following the diagnosis of gastrointestinal perforation veracity. Results 38 cases taken in abdominal ultrasound preoperative in 60 patients, 9 cases had free gas below the diaphragm, diagnosis of gastrointestinal perforation. 30 cases take upright abdominal plain film examination preoperative, 8 cases had free gas below the diaphragm, diagnosis of gastrointestinal perforation. 11 cases taken MSCT preoperative, 10 cases had free gas in intraperitoneal, 9 cases perforation explicitly. Enhanced MRI diagnostic lower gastrointestinal perforation caused free gas was better than upright KUB and abdominal ultrasound, P〈0.05, had difference statistical significance. Conclusion Take MSCT abdominal scanning for lower gastrointestinal perforation, can be found lower gastrointestinal perforation cause intraperitoneal free gas timely.
