螺旋CT动态增强对肠梗阻的诊断价值

目的探讨螺旋CT对肠梗阻的诊断价值。方法回顾性分析52例经手术证实的肠梗阻病例的螺旋CT影像资料,并将其诊断结果与手术、病理结果进行对照分析。结果螺旋CT诊断肠梗阻的准确性100%,对肠梗阻部位判断的准确性约92.3%,肠梗阻病因判断的准确性约90.0%,对绞窄性肠梗阻诊断的准确率约94.2%;其中包括肠道肿瘤16例,粘连性肠梗阻18例,肠扭转7例,肠系膜血管栓塞2例,胆石性肠梗阻2例,粪石性肠梗阻1例,脐疝1例,腹股沟疝3例,阑尾炎5例,腹腔脓肿1例。结论螺旋CT在显示肠梗阻的存在、确定肠梗阻部位和梗阻原因以及对肠道血运状况判断方面具有很高的临床价值。

Spiral the CT evaluation of bowel obstruction

Objective To evaluate the diagnostic value of spiral CT of bowel obstruction.Methods All of 52 patients with bowel obstruction comfirmed by pathology underwent spiral CT examination were reviewed retrospectively,the diagnostic results of spiral CT were compared with operation and pathology results.Results The correct proportions of diagnosis of intestinal obstruction for spiral CT were 100%,obstructive locations 92.3%,the obstructive cause were 90.0%,the correct proportions of diagnosis of strangulated intestinal obstruction 94.2%.Including primary or secondary neoplasms(16/52),abhesions(18/52),bowel torsion(7/52),mesenteric vessal thrombosis(2/52),gallstone(2/52),faeces(1/52),hernias(3/52),appendicitis(5/52),celiac abscess(1/52).Conclusions Spiral CT has great clinical value for evaluating the site,level,and cause of obstruction,and the blood supply of the bowel obstruction.
