【摘要】 为评价磁共振成像(MRI)在复杂性肛瘘术前精准诊断,指导个体化治疗的应用价值,选取120例复杂性肛瘘患者,随机分为观察组和对照组各60例。观察组术前采用MRI对肛瘘精准诊断后手术;对照组采用传统方法对肛瘘诊断后手术。比较两组一次性治愈率,术后并发症等情况。结果显示,观察组一次性手术治愈率为97%,明显高于对照组的82%,差异有统计学意义(P <0.05)。术后观察组肛门狭窄发生率为5%,低于对照组的7%,但差异无统计学意(P>0.05)。观察组疗程为25d短于对照组的36d,差异有统计学意义(P <0.05)。结果表明,MRI术前能精准判定肛瘘与肛门直肠的解剖关系,明确外口和内口的位置及瘘管走行。可减少术中不必要的损伤,达到术后恢复快,复发率低的目的。更多还原

【Abstract】 This study was to evaluate the accuracy diagnosis before surgery for complex anal fistula by using MRI,so as to direct personalized treatment,randomly divided 120 cases of this fistula into observation group(60 cases,performed surgery following MRI for accuracy diagnosing anal fistula)and control group(60 cases,while routine diagnostic method);then compared both groups’ primary curative rate,and postoperative complication,etc.As results,in primary curative rate(97% vs 82%),and in treatment course(25 d vs 36 d)observation group was significantly and respectively higher and shorter than control group(all,P<0.05);after surgery,even the incidence of anal stenosis in observation group was lower than control group(5% vs 7%),but there was no statistical difference(P >0.05).Results show that due to MRI accuracy judging the anatomic relationship of anal fistula and ano-rectum,and showing the location of outlet and inner-ora,as well as fistula vessels trend direction,thus it can make intraoperatively unnecessary trauma reduced,and promote postoperative recovery fastly,and recurrence rate declined.更多还原
