Results of 54 sonographic examinations of patients referred for suspected or known small intestinal obstruction were retrospectively correlated with surgical findings, and the diagnostic value of sonography regarding presence, level, and cause of obstruction was compared with that of plain abdominal radiography. The diagnosis of obstruction was correct in 89% of cases with sonography and in 71% with plain radiography. The level of obstruction was correctly predicted in 76% of cases with sonography and in 51% with plain radiography. The cause of obstruction was correctly predicted in 20% of cases with sonography and in 2% with plain radiography. The authors conclude that use of sonography in evaluating patients with bowel obstruction may be helpful in confirmation of the presence of obstruction, in determination of the level of obstruction, and in identification of the cause of obstruction.
对54例因疑似或已知小肠梗阻而转诊患者的超声检查结果进行回顾性分析，并与手术结果进行相关性分析，同时将超声检查在梗阻的存在、部位及病因方面的诊断价值与腹部平片进行比较。超声检查对梗阻的诊断正确率为89%，腹部平片为71%。超声检查对梗阻部位的正确预测率为76%，腹部平片为51%。超声检查对梗阻病因的正确预测率为20%，腹部平片为2%。作者得出结论，在评估肠梗阻患者时使用超声检查可能有助于确认梗阻的存在、确定梗阻部位以及识别梗阻病因。
