摘要
目的:分析磁共振(MRI)成像肛瘘诊断征像分析对临床手术的应用价值。方法:选取收治并经手术确诊为肛瘘的60例患者为观察组,另选取60例进行健康体检的志愿者为对照组。两组均采用MRI扫描仪检测,比较两组MRI成像参数,比较观察组与对照组手术分型及肛瘘内口、外口及瘘管情况。结果:与对照组比较,观察组ADC值下降,主瘘管信号强度、支管信号强度上升,差异具有统计学意义(P<0.05)。MRI成像对肛瘘患者括约肌间型、经括约肌型、括约肌上型、括约肌外型、皮下型、复杂性的诊断准确率分别为86.96%、86.67%、90.00%、85.71%、66.67%、50.00%,MRI成像对肛瘘内口及瘘管诊断总准确率为85.00%,差异无统计学意义(P>0.05)。MRI成像对肛瘘患者括约内口、主瘘管、支管、外口、脓肿的诊断准确率分别为93.33%、95.35%、76.92%、95.12%、93.33%,MRI成像对肛瘘内口及瘘管诊断总准确率为92.99%,差异无统计学意义(P>0.05)。结论:MRI成像可对肛瘘患者分型的准确率较高,并且可以显示肛瘘内口、外口及瘘管位置、走形及数量,可为临床手术的治疗提供重要指导信息。
Objective To analyze the value of MRI imaging diagnosis of anal fistula in clinical surgery.Method Sixty patients who were diagnosed with anal fistula after surgery were selected as the observation group, and another 60 volunteers who underwent a physical examination in hospital were selected as the control group. Both groups were detected by MRI scanner, compared the MRI imaging parameters of the two groups, compared the observation group and the surgical classification, and the results of the internal or external fistula and fistula of the anal fistula. Results Compared with the control group, the ADC value of the observation group decreased, the signal intensity of the main fistula and the branch signal intensity increased, and the difference was statistically significant(P<0.05). The diagnostic accuracy of MRI imaging for the intersphincter type, transsphincter type, suprasphincter type, sphincter outer type, subcutaneous type, and complexity of anal fistula patients were 86.96%, 86.67%, 90.00%, 85.71%, 66.67%, and 50.00%, respectively. The total accuracy of MRI imaging in the diagnosis of the internal orifice and fistula of anal fistula was 85.00%(P>0.05). The diagnostic accuracy rates of MRI imaging for the internal sphincter, main fistula, branch, external orifice, and abscess in patients with anal fistula were 93.33%, 95.35%, 76.92%, 95.12%, and 93.33%, respectively. The total diagnostic accuracy of MRI imaging for the internal orifice and fistula of anal fistula The accuracy rate was 92.99%(P>0.05). Conclusion MRI imaging can classify patients with anal fistula with a high accuracy rate, and can display the position, shape and quantity of the internal opening, external opening and fistula of the anal fistula, which can provide important guidance information for the treatment of clinical surgery.
