目的探讨三维超声可视化渲染重建在肛瘘诊断中的应用价值。方法回顾性分析在我院经手术确诊为肛瘘患者67例的超声资料,术前均行二维超声检查及三维超声可视化渲染重建,将三维超声诊断结果和术中所见进行比较。结果 (1)定位内口63例,内口位于括约肌间齿状线处57例,位于括约肌间齿状线处以上6例;(2)定位主管65例,其中括约肌间瘘32例,经括约肌瘘27例,括约肌上瘘6例;定位支管41例,支管走行变化多样。结论三维超声可视化可以较清晰地显示内口及瘘管的主管、支管的走行情况,为临床治疗肛瘘提供影像学依据。
Objective To explore the value of three-dimensional visualized visualization reconstruction in the diagnosis of anal fistula. Methods The clinical data of 67 cases of anal fistula surgically diagnosed in our hospital were retrospectively analyzed. Two-dimensional ultrasonography and three-dimensional visualized reconstruction were performed preoperatively. The results of three-dimensional ultrasonography were compared with those of intraoperative findings. Results (1) 63 cases were located in the inner mouth, the inner mouth was located in the sphincter of 57 cases, located in the sphincter of more than 6 cases; (2) 65 cases of localization director, including sphincter of the fistula in 32 cases, Fistula in 27 cases, sphincter fistula in 6 cases; positioning branch in 41 cases, branch walk varied. Conclusion Three-dimensional visualization of ultrasound can clearly show the inner tube and the fistula of the superficial and branch of the walking conditions for the clinical treatment of anal fistula to provide imaging basis.
