探讨术前高频超声检查腹股沟斜疝与直疝的诊断价值。

选取2018年6月至2019年6月东方市人民医院行腹股沟疝手术的患者372例，所有患者先行系统外科查体、X线腹透，在使用超声诊断仪进行鉴别诊断。分析腹股沟斜疝与直疝的鉴别点；比较患者术前超声诊断、术前外科查体诊断与手术结果；比较术前超声诊断与术前外科查体的准确性、特异性、假阴性、阳性预测值、敏感性。

372例患者手术判定斜疝304例，直疝68例；超声诊断准确率与手术结果无明显差异（P>0.05）；外科查体准确率低于手术结果准确率（P<0.05）；超声诊断的准确性、特异性、阳性预测值、敏感性均高于外科查体，假阴性低于外科查体（P<0.05）。

腹股沟斜疝与直疝采用术前高频超声检查诊断具有可重复、无创、快捷、操作简单、显像清晰等优点，诊断结果较准确，疝的类型可准确鉴别，为手术中疝口的寻找提供较为准确的指导，为手术提供可靠的依据。

To explore the diagnostic value of preoperative high frequency ultrasound examination in indirect and direct inguinal hernia.

A total of 372 patients who underwent inguinal hernia surgery from June 2018 to June 2019 in Dongfang People's Hospital were selected. All patients underwent systematic surgical examination, X-ray abdominal dialysis, and differential diagnosis using ultrasonic diagnostic equipment. The differential points of indirect inguinal hernia and direct inguinal hernia were analyzed; the preoperative ultrasound diagnosis, preoperative surgical examination and surgical results were compared; the accuracy, specificity, false negative, positive predicted value, and sensitivity of preoperative ultrasound diagnosis and preoperative surgical examination were compared.

Among the 372 patients, 304 cases were diagnosed as indirect hernias and 68 cases as direct hernias by the operation. There was no significant difference between the accuracy of ultrasound diagnosis and the results of surgery (P>0.05); the accuracy of surgical examination was lower than that of surgery results (P<0.05). The accuracy, specificity, positive predictive value, and sensitivity of ultrasound diagnosis were higher than those of surgical examinations, and false negatives were lower than those of surgical examinations (P<0.05).

Preoperative high-frequency ultrasound diagnosis of indirect and direct inguinal hernia has the advantages of reproducibility, non-invasiveness, quickness, simple operation, and clear imaging, etc. The diagnosis result is more accurate, and the type of hernia can be accurately identified. And it provides more accurate guidance for hernia defect finding and a reliable basis for surgery.
