摘　　要：目的研讨不同诊断方案对复杂性肛瘘应用价值差异。方法选取2022年5月—2023年5月东营市河口区人民医院疑似复杂性肛瘘患者62例,以临床诊断结果检测为金标准,对所有患者开展常规磁共振扫描与磁共振平扫联合弥散加权成像扫描诊断,比较不同诊断方案的诊断效能以及诊断符合率。结果62例疑似复杂性肛瘘患者经临床诊断确诊54例。磁共振平扫联合弥散加权成像扫描诊断的诊断灵敏度、特异度、准确度均高于常规磁共振扫描诊断,差异均有统计学意义(P均<0.05)。磁共振平扫联合弥散加权成像扫描诊断在低位复杂性肛瘘检出率100.00%(43/43)与高位复杂性肛瘘检出率90.91%(10/11)均高于常规磁共振扫描诊断的低位复杂性肛瘘检出率81.40%(35/43)与高位复杂性肛瘘检出率45.45%(5/11),差异均有统计学意义(χ^(2)=8.821、5.238,P均<0.05)。结论常规磁共振扫描与磁共振平扫联合弥散加权成像扫描在临床一定诊断意义,但对于复杂性肛瘘疾病,磁共振平扫联合弥散加权成像扫描疾病检出率更高。Objective To study the difference of application value of different diagnostic schemes for complex anal fistula.Methods A total of 62 suspected complex anal fistula patients from Hekou District People's Hospital in Dongying City from May 2022 to May 2023 were selected.Clinical diagnostic results were used as the gold standard to conduct routine magnetic resonance imaging(MRI)scans and MRI plain scans combined with diffusion-weighted imaging(DWI)scans for all patients.The diagnostic efficacy and accuracy of different diagnostic schemes were compared.Results Sixty-two suspected patients with complex anal fistula were clinically diagnosed and 54 cases were confirmed.The diagnostic sensitivity,specificity,and accuracy of magnetic resonance plain scan combined with diffusion-weighted imaging scan were higher than those of conventional magnetic resonance scan,respectively,the differences were statistically significant(all P<0.05).The detection rates of low complexity anal fistula and high complexity anal fistula diagnosed by magnetic resonance plain scan combined with diffusion-weighted imaging scan were 100.00%(43/43)and 90.91%(10/11),respectively,higher than those diagnosed by conventional magnetic resonance scan,which were 81.40%(35/43)and 45.45%(5/11),respectively,the differences were statistically significant(χ^(2)=8.821,5.238,both P<0.05).Conclusion Conventional magnetic resonance scan and magnetic resonance plain scan combined with diffusion-weighted imaging scan have certain clinical diagnostic significance,but for complex anal fistula diseases,the latter is recommended to ensure the detection rate of the disease,and can be used as the first diagnosis of complex anal fistula.
