摘　　要：目的探讨肛周超声(端扫式腔内线阵、经直肠腔内360°旋转探头)在肛瘘诊断中的价值。方法采用日立HD15对42例肛瘘患者术前行肛周超声检查,外口探查均采用体表线阵探头扫查,腔内超声探查内口、主管及支管走行,将术后结果与术前超声结果对照,探讨端扫式腔内线阵探头与旋转式腔内探头对内口、主管、支管、肛瘘分型诊断的符合率。结果体表线阵探头诊断外口符合率为97.6%(41/42)。腔内线阵探头诊断肛瘘内口符合率97.6%(41/42),主管符合率97.6%(41/42),支管符合率93.1%(27/29),分型符合率分别为95.2%(40/42)(按病变程度)、97.6%(41/42)(Park法)。旋转探头诊断肛瘘内口符合率92.8%(39/42),主管符合率95.2%(40/42),支管符合率86.2%(25/29),分型符合率分别为92.8%(39/42)(按病变程度)、92.8%(39/42)(Park法)。腔内线阵扫查在判断肛瘘内口、主管、支管、分型与手术结果符合率均高于旋转式腔内扫描,但差异均无统计学意义(P>0.05)。结论端扫式腔内线阵探头、旋转腔内探头均能清楚显示瘘管走行方向,瘘管与肛门括约肌、肛提肌的关系,为临床医生制定手术方式提供更多依据。Objective To explore the value of linear endoprobe and rotating endoprobe in the diagnosis of anal fistula.Methods The preoperative analyzed about 42 cases of anal fistula patients with linear endoprobe and rotating endoprobe in Hitachi HD15.We used surface high frequency probe to examine external opening and linear endoprobe、rotating endoprobe to search for internal opening、the direction of main fistula and side fistula.The post operative results were compared with the preoperative ultrasound results and explored the coincidence rate of internal orifice、main tube、branch tube and fistula type.Results The coincidence rate of external opening was 97.6%(41/42)using high frequency probe.With the rectal cavity line array probe,the diagnosis coincidence rate were97.6%(41/42)(internal orifice),97.6%(41/42)(the main pipe),93.1%(27/29)(branch pipe),95.2%(40/42)(classification according to lesion degree),97.6%(41/42)(classification Park method).With the rotating probe,the diagnosis coincidence rate were 92.8%(39/42)(internal orifice),95.2%(40/42)(the main pipe),86.2%(25/29)(branch pipe),92.8%(39/42)(classification according to lesion degree),92.8%(39/42)(classification Park method).The result showed that the coincidence rate of intrarectal line scan in internal orifice,main pipe,branch pipe and anal fistula type compared with the rotation scan were higher,but the difference was not Statistical significance(P>0.05).Conclusion The linear endoprobe and rotating endoprobe can clearly show the direction of fistula and the relationship between the fistula and the anal sphincter and levator ani muscle,and provide valuable information for surgical strategy.
