The purpose of this study was to determine whether sonography provides additional clinical information in patients suspected of small bowel (SB) obstruction. During a period of 30 months, in a prospective setting, we evaluated with sonography 123 patients suspected of SB obstruction. Sonographic examinations of the entire abdomen were performed with state-of-the-art, real-time, grey-scale equipment. Fourteen patients were labelled 'gassy' and no added information was provided following abdominal ultrasound. Sonography confirmed the SB obstruction in 82 cases with 5 false positives, resulting in a specificity of 82.1 %. Sonographic examinations were negative in 27 cases with 4 false negatives and a sensitivity of 95 %. The accuracy was 91.7 % when the 'gassy' patients were excluded and 81.3 % overall. The aetiology of the ileus was detected by sonography in 13 cases of paralytic ileus (54.1 %) and in 57 cases of mechanical ileus (71.4 %). It is concluded that ultrasound, which is a non-invasive, portable and even bedside imaging procedure, appears accurate in confirming a SB obstruction and in determining the aetiology of SB obstruction.
本研究的目的是确定超声检查能否为疑似小肠梗阻的患者提供额外的临床信息。在30个月的时间里，我们对123例疑似小肠梗阻的患者进行了前瞻性超声评估。使用最先进的实时灰阶设备对整个腹部进行超声检查。14例被标记为“气体过多”，腹部超声检查后未提供额外信息。超声检查确诊82例小肠梗阻，其中5例假阳性，特异性为82.1%。27例超声检查为阴性，其中4例假阴性，敏感性为95%。排除“气体过多”的患者后，准确率为91.7%，总体准确率为81.3%。超声检查发现13例麻痹性肠梗阻（54.1%）和57例机械性肠梗阻（71.4%）的肠梗阻病因。结论是，超声作为一种非侵入性、便携甚至可在床边进行的成像检查方法，在确诊小肠梗阻和确定小肠梗阻病因方面似乎是准确的。
