Abstract
Objective To investigate the clinical value of high frequency ultrasound in detecting foreign bodies in soft tissue.Methods From January 2016 to June 2016,215 hospitalized patients suspected of "soft tissue foreign body residue" and treated in Department of General Surgery,Shanghai Eighth Hospital Affiliated to Jiangsu University were selected.All patients underwent preoperative high frequency ultrasound examination.Ultrasound guided surgical exploration results as the gold standard,the clinical value of high frequency ultrasound in detecting different kinds of foreign bodies in soft tissue was analyzed.Results In 215 cases, 307 soft tissues were examined.There were 275 foreign bodies confirmed in the operation,and there were no foreign bodies confirmed in the 32 operation.Two hundred sixty-two positive foreign bodies were detected by high frequency ultrasound before operation, 3 were misdiagnosed, 45 foreign bodies were negative, and 16 were missed.The sensitivity was 94.2%,specificity was 90.6%,the missed diagnosis rate was 5.8%,the misdiagnosis rate was 9.4%,the accuracy was 93.8%,the positive likelihood ratio was 10.046,negative likelihood ratio was 0.064,Youden index was 0.848.Conclusion High frequency ultrasound is cheap,safe and efficient.It has high clinical value in the detection of foreign bodies in soft tissue.关键词
