The clinical research of internal opening of anal fistula located by end-scan intracavity convex-array and high frequency linear array ultrasonic probe ZHANG Cuihong，YAN Youqing，CHEN Zhengguang*，MEI Jian. *Department of Radiology， Dongzhimen Hospital Affiliated to Beijing University of Traditional Chinese Medicine，Beijing 100700，China. ［Abstract］ Objective：To explore the clinical value of transvaginal or perineal ultrasound end-scan intracavity convex-array probe in locating the internal opening of anal fistula. Methods：Sixty-five patients with anal fistula were selected and ultrasound was performed by end-scan intracavity convex-array and high frequency linear array probe before operation. The location，size and number of fistula were recorded at the lithotomy position. The sensitivity，specificity and consistency of the two probes were compared with pathological results as the reference standard. Results：In 65 patients，85 internal openings and 91 fistulas were found during operation，including 68 internal openings and 70 fistulas detected by high frequency linear array probe and 79 internal openings and 82 fistulas by end-scan intracavity convex-array probe. There was a good consistency between the results of ultrasonography by end-scan intracavity convex-array probe and pathology （K=0.653），with sensitivity of 92.9% and 90.1%， specificity of 73.7% and 68.4% and conformity of 89.4% and 86.3% for internal openings and fistulas，respectively. The consistency was moderate between the results of ultrasonography by high frequency linear array probe and pathology （K=0.425），with sensitivity of 80.0% and 80.2%，specificity of 68.4% and 63.1% and conformity of 77.8% and 77.3% for internal openings and fistulas，respectively. Conclusions：The consistency is good between the results of ultrasonography by end-scan intracavity convex-array probe and pathology，with sensitivity and specificity higher than those of high frequency linear array probe. ［Key words］ Rectal fistula；Ultrasonography
［摘要］ 目的：探讨应用端扫式凸阵腔内探头经阴道或会阴部超声检查定位肛瘘内口的临床应用价值。 方法：选取 65 例肛瘘 患者，术前分别通过高频线阵探头与端扫式凸阵腔内探头检查，按照截石位 12 点时钟方法记录内口位置、大小及瘘管数量。 以手 术病理结果为参照标准，分析对比 2 种探头的诊断敏感度、特异度及其与病理结果的一致性。 结果：65 例手术共发现肛瘘内口 85 个 ，瘘 管 91 个 ；应 用 高 频 线 阵 超 声 探 头 术 前 共 诊 断 肛 瘘 内 口 68 个 ，瘘 管 70 个 ；应 用 端 扫 式 凸 阵 腔 内 探 头 术 前 共 诊 断 肛 瘘 内 口 79 个，瘘管 82 个。 端扫式凸阵腔内探头诊断肛瘘内口与手术病理结果的一致性较好（K=0.653），诊断肛瘘内口的敏感度 92.9%、 特异度 73.7%、符合率 89.4%，诊断瘘管的敏感度 90.1%、特异度 68.4%、符合率 86.3%。 高频线阵探头诊断肛瘘内口与手术病理结 果 的 一 致 性 一 般 （K=0.425），诊 断 肛 瘘 内 口 的 敏 感 度 80.0% 、 特 异 度 68.4% 、 符 合 率 77.8% ； 诊 断 瘘 管 的 敏 感 度 80.2% 、 特 异 度 63.1%、符合率 77.3%。 结论：端扫式凸阵腔内超声探头诊断肛瘘内口与手术病理结果一致性较好，其敏感度及特异度均优于高频 线阵探头。
