| 摘 要： | 目的 探讨腹部Ｂ超对早期绞窄性肠梗阻的诊断价值。方法 对７４例经手术或保守治疗证实的小肠梗阻患者进行分析。其中绞窄性肠梗阻１６例，单纯性肠梗阻５８例。对比研究临床物理学诊断、实验室检查（ＷＢＣ升高）、Ｘ线检查和腹部Ｂ超对绞窄性肠梗阻的诊断价值。比较各项指标的敏感性、特异性、阳性预测值、阴性预测值及符合率。结果 超声检测的敏感性为８１．３％（１３／１６），特异性为８９．７％（５２／５８），符合率为８

| Abstract: | Objective To investigate the diagnostic value of ultrasonography for early strangulation loop in intestinal obstruction.Methods Seventy four patients with small bowel obstruction were analyzed,out of which 16 were strangulated,and 58 were simple obstuction.The diagnostic value of clinical physical,laboratory (WBC>10 10 /L),X rays,and abdominal ultrasonographic examination for early strangulation were comparatively studied.Their sensitivity,specificity,positive predictive value,negative predictive value and efficiency were calculated respectively.Results The sensitivity,specificity,and efficiency of ultrasonography for strangulation was 81.3 %(13/16), 89.7 %(52/58),and 89.2 %;while those of X rays was 25.0 %, 94.8 %,and 79.7 %,respectively.The efficiency of clinical and laboratory examination is 75.7 % and 79.7 %.Conclusions Abdominal B type ultrasonography is of great value for early diagnosis of strangulated small bowel obstruction and should surely be taken as a routine examination. |
