摘要
目的评价多层螺旋CT对非创伤性下消化道穿孔的诊断价值。方法回顾性分析35例经手术证实的非创伤性下消化道穿孔的CT表现。结果 35例中,19例X线腹平片发现腹部游离气体,阳性率为54.3%(19/35),MSCT中,31例见游离气体影,阳性率达88.6%(31/35)。二者对游离气体发现的差异具有统计学意义(P=0.04),CT定位正确率达83.9%(26/31)。病因诊断方面,术前正确诊断29例,诊断正确率达82.9%(29/35)。结论 MSCT对于非创伤性下消化道穿孔具有较高的诊断价值。
Objective To evaluate the diagnose value of multi-slice CT(MSCT) in non-traumatic small lower gastrointestinal tract perforation.Materials and Methods The CT imaging findings of 35 patients with lower gastrointestinal tract perforation were reviewed retrospectively. Results In the 35 patients, plain abdominal radiographs depicted free air in 54.3% of patients (19/35) and MSCT depicted free air in 88.6% (31/35) of patients. Statistically significant differences were detected between them (P=0.04).The sites of perforation were correctly preoperative diagnosed in 83.9% (26/31) of the patients on CT imaging.And the cause of perforation were correctly preoperative diagnosed in 82.9% (29/35) of the patients. Conclusion CT is useful in the diagnose of non-traumatic lower gastrointestinal tract perforation.
