Successful management of anal fistulas depends upon accurate assessment of the primary tract and any secondary extensions. Preoperative imaging has, to date, been disappointing.
A prospective study of 35 patients with a clinical diagnosis of fistula-in-ano was performed comparing magnetic resonance imaging with the independently documented operative findings. Magnetic resonance imaging was also compared with anal endosonography in 20 patients.
Magnetic resonance imaging is accurate and demonstrates pathology missed at surgery by experienced coloproctologists. Magnetic resonance imaging is superior to anal endosonography.
Magnetic resonance imaging is advocated as the method of choice when imaging is required for anal fistulas.
肛瘘的成功治疗取决于对主瘘管及任何继发延伸的准确评估。迄今为止，术前影像学检查的结果并不理想。
对35例临床诊断为肛瘘的患者进行前瞻性研究，将磁共振成像与独立记录的手术结果进行比较。还对20例患者的磁共振成像与肛门内超声检查进行了比较。
磁共振成像准确，能显示经验丰富的结直肠外科医生在手术中遗漏的病变。磁共振成像优于肛门内超声检查。
当需要对肛瘘进行影像学检查时，提倡使用磁共振成像作为首选方法。
