摘　　要：目的:探讨超声显像(US)对远端回肠和结肠梗阻的诊断价值。方法:统计60例拟诊小肠远端梗阻(small bowel obstruction,SBO)和结肠梗阻(LBO)患者的US所见与腹部X-线平片(abdominal X-ravplainfilm,AXR)及手术结果,将US所见有无梗阻及梗阻水平与AXR比较,评价其诊断价值。结果:45例证实梗阻,US正确识别梗阻44例(97.8％)、肯定病因为36例(80.0％),US诊断梗阻的灵敏性为97.8％、特异性为80％,AXR的上述值分别为79％和53％。结论:US在决定有无SBO和LBO及原因时有应用价值。Objective: To evaluate the usefulness of US in determining the site and cause of small and large bowel obstruction. Methods: US findings in 60 patients with suspected distal small bowel or colonic obstruction were observed whether they were correlated with final surgical and radiological diagnosis. The diagnostic value of US was compared with abdominal X-ray (AXR) plain films for the presence and level of obstruction. Results: Forty-five patients were confirmed to be obstructed. US correctly identified obstruction in 44/ 45 and the cause in 36/45(80%). Overall sensitivity of US for obstruction was 98% and specifictity 80% .compared with 79% and 53% respectively for AXR. Conclusions: US is useful in determining the presence and cause of distal ileal and colonic obstruction.
