摘要
为探讨磁共振成像(MRI)在复杂性肛瘘诊断中的应用价值,对天津市人民医院收治的58例复杂性肛瘘患者术前进行一般检查和MRI检查,将术前一般检查结果及MRI检查结果与手术结果进行比较。结果显示,瘘管在T2WI像上表现为低信号,在T2WI像和T2WI抑脂像上表现为高信号;脓肿则表现为马蹄型或不规则型,在T1WI像上为低信号,T2WI像上为高信号;肛瘘的内口表现为点状强化或者直肠肛门内括约肌的连续性中断。术前一般检查对于肛瘘内口的位置以及主管和支管走行方向的诊断符合率分别为60.3%(35/58)、65.5%(38/58)和53.4%(31/58);而MRI对于肛瘘内口的位置以及主管和支管走行方向的诊断符合率分别为79.3%(46/58)、100%(58/58)和94.8%(55/58)。MRI对于复杂性肛瘘内口的位置以及主管和支管走行方向的诊断符合率明显高于术前一般检查,差异有统计学意义,均P〈O.05。结果表明,术前MRI检查能够清晰显示复杂性肛瘘内口、主管位置和支管的走向,与手术结果具有良好的一致性,具有极高的术前诊断价值,值得临床推广应用。
In order to explore the application value of magnetic resonance imaging(MRI) in the diagnosis of complex anal fistula,this study took both common inspect and MRI to 58 patients admitted in the people's hospital of Tianjin municipality hospital before operation, then compared examination results of both meth- ods and operative results.As results,T1WI inhibiting fat image of fistula was low signals,T2WI image and T2WI inhibiting fat image was high signals;image of abscess was horse-shaped or irregular,T^WI image was low signal,T2WI image was high signal;image of inner opening of fistula was point-like intensity,or continous interrupt of recto-anal internal sphincter;the common inspect before operation had diagnosis accordance rate in inner opening position as 60.3% (35/58), in main tract distribution as 65.5% (38/58), in branch distribution as 53.4 % ( 31/58), respectively; while, MRI, as 79.3% ( 46/58 ), as 100% ( 5 8/58), as 94.8 0/40 (55/58), respectively;apparently the diagnosis accordance rate of MRI in all three items was signifi- cantly higher than that of common inspeCt( P 〈0.05,at all).Results show that before operation MRI can clearly show the inner opening position,the distribution of main and branch tract,and better accordance with operative results,thus has the highest preoperative diagnosis value, it is worthy to be popularized to use clinically.
