粘连性肠梗阻及其亚型的CT诊断

CT Diagnosis of Adhesive Intestinal Obstruction and Subtype

目的探讨多层螺旋CT对粘连性肠梗阻分型的诊断价值。方法回顾性分析经手术、病理证实的18例粘连性肠梗阻病例的CT图像。结果 18例肠梗阻(100%)诊断明确,其中4例肠壁坏死均有CT直接征象支持。10例(55.6%)的CT表现能明确肠梗阻分型,3例广泛粘连性肠梗阻回肠远段见明显"小肠粪性纤维素征"。结论多层螺旋计算机扫描能够提供部分粘连性肠梗阻的粘连类型,使临床诊断明确、具体,指导临床选择一个更加适合的治疗方式。

Objective To evaluate the diagnostic value of spiral CT of bowel obstruction and subtype.Methods CT signs in 18 cases of patients with adhesive intestinal obstruction proved by surgery were analyzed retrospectively.Results The proportions of correct diagnosis of intestinal obstruction for spiral CT were 100%,4 cases of strangulated intestinal obstruction with bowel necrosis have CT signs apparently.10 patients（55.6%）CT manifestations can display subtypes of bowel obstruction,3 cases with extensive adhesive obstruction show ＂small bowel feces sign＂ obviously.Conclusion CT can diagnose adhesive intestinal obstruction correctly,and give more adhesion information of the subtypes of adhesive obstruction to clinician for suitable clinical treatment.
