机械性肠梗阻多层螺旋CT诊断及其临床意义

Multi-slice Spiral CT Diagnosis and Its Clinical Significance for Mechanical Intestinal Obstruction

目的探讨多层螺旋CT(MSCT)对机械性肠梗阻的诊断价值及其临床意义。方法回顾分析2008年6月～2011年2月我院经手术及病理检查证实为机械性肠梗阻58例患者的MSCT扫描结果。结果 MSCT初诊与手术病理或全愈随访复查相符54例,敏感性94.3%,特异性91.3%,准确率93.1%。引起梗阻的主要病因有肠粘连、肠肿瘤、肠扭转、肠套叠、结石及粪石等。不同原因引起机械性肠梗阻的MSCT影像表现各具特征。结论 MSCT对机械性肠梗阻诊断及鉴别诊断具有重要的临床意义。

Objective To investigate the value and clinical significance of muhi-slice spiral CT （ MSCT ） in the diagnosis of mechanical intestinal obstruction. Methods From June 2008 to February 2011,58 patients with mechanical intestinal obstruction determined by surgery and pathology in our hospital were retrospected and their MSCT scan results were analyzed. Results 54 patient＇ s MSCT results were consistent with surgery and pathology or follow-up examination after cure. Sensitivity and accuracy were 94.3%,91.3% and 93.1%, respectively. The main causes of intestinal obstruction included adhesions, intestinal cancer, volvulus, intussusception, stones and bezoars and so on. MSCT imaging performance had each characteristics associated with different causes of mechanical intestinal obstruction. Conclusion MSCT has important clinical significance for diagnosis and differential diagnosis of mechanical intestinal obstruction.
