| 目的 探讨端扫式凸阵腔内探头联合高频探头经会阴部超声术前检查在肛瘘诊断中的临床价值。方法 对临床拟诊肛瘘的87例患者术前进行超声检查,频率5～12MHz的线阵探头结合触诊和视诊检查外口和瘘管,频率3～10MHz端扫式凸阵腔内探头经会阴检查内口和瘘管,确定肛瘘类型和位置,Kappa检验分析超声与手术结果的一致性。结果 87例超声诊断肛瘘和手术结果一致性高,超声诊断肛瘘及其分型、内口、瘘管、外口的准确率分别是75.86%、81.61%、80.64%、83.17%、87.23%,和手术结果一致性高(Kappa=0.344,0.344,0.298,0.407,0.626;p值均为0.000)；端扫式凸阵腔内探头经会阴诊断肛瘘全部表现为高回声外括约肌的中断缺损,并与低回声的瘘管相连。结论 端扫式凸阵腔内探头联合高频探头经会阴超声检查肛瘘具有较高的临床价值,是超声检查肛瘘方法的有力补充。 |

| Objective To explore the clinical value of end-fire endoprobe transperineal ultrasonography combined with high-frequency’s in preoperative diagnosing anal fistula.Methods 87 patients with clinical anal fistula underwent ultrasound examination before operation .The external opening and fistula were traditionally observed with linear transducer of 5-12MHz combined with palpation and visual examination, and the internal opening and fistula were transperineally examined with end-fire endoprobe of 3-10MHz. All cases’s ultrasonography preoperatively diagnosed the classification and location of anal fistula, the results of ultrasound and intraoperation findings was analyzed by Kappa test.Results In 87 patients ,there were high consistency between ultrasound diagnosing of anal fistula and the intraoperation finds. The accuracy of ultrasound diagnosing of anal fistula and its classification, internal opening, fistula, internal opening were 75.86%, 81.61%, 80.64%, 83.17% and 87.23%,respectively. There was high consistency with intraoperation findings(Kappa = 0.344, 0.344, 0.298,0.407 and 0.626 respectively, P = 0.000). The internal opening was shown as defect of high echoes in the external sphincter,and the defect connected with low echo fistula.Conclusion The end-fire endoprobe transperineal ultrasonography combined with high-frequency’s is valuable in preoperative diagnosing in anal fistula, which is is a powerful supplement to the method of ultrasound examination. |
