多排螺旋CT在急性肠梗阻诊断中的应用(附20例分析)

Application MDCT in diagnosing acute bowel obstruction(with a report of 20 cases)

目的探讨多排螺旋CT对急性肠梗阻的诊断价值。方法搜集经手术病理证实的20例急性肠梗阻病例,且均做过CT检查,对其CT征象进行分析和研究。结果20例急性场梗阻病人CT术前诊断18例,CT报告梗阻部位正确的为17例,病因诊断正确的为16例,与手术结果对照,符合率分别为94.4%和88.8%。结论多排螺旋CT对急性肠梗阻的部位、病因的诊断率高,可做为肠梗阻首选检查方法之一。

Objective To evaluate the value of multidetecter computed tomography （MDCT） in the diagnosis of acute bowel obstruction. Methods CT signs were analyzed in 20 patients with acute bowel obstruction which had been pathologically confirmed through operation and CT examination. Results 18 cases had been diagnosed by CT before operations. The obstructive parts were accurately reported in 17 cases, and the causes of acute bowel obstruction were confirmed in 16 cases by CT. Conclusion As MDCT has high diagnostic rate for finding the site and cause of obstruction （94.4% and 88.8% respectively） , it can be the first choice in diagnosing acute bowel obstruction.
