摘　　要：目的探索螺旋CT三维重建在基层医院复杂性肛瘘诊断中的价值。方法选取2020年6月-2022年6月我院收治的复杂性肛瘘患者98例,患者术前均给予MRI和螺旋CT三维重建技术检查,以手术结果作为金标准,分析螺旋CT三维重建技术对复杂性肛瘘内口、瘘管诊断的准确性以及肛瘘分级诊断的准确性。结果98例患者术中明确诊断为复杂性肛瘘,其中Ⅰ级、Ⅱ级、Ⅲ级分别为51例、36例、11例,共发现112个内口、132条瘘管。MRI、螺旋CT三维重建对复杂性肛瘘诊断准确率均为100.00%,对分级诊断准确率分别为98.98%、96.94%,对肛瘘内口、瘘管诊断准确率分别为93.75%、96.21%和91.96%、94.70%。以手术结果作为金标准,螺旋CT三维重建技术与MRI对复杂性肛瘘内口定位、瘘管检出、分级诊断准确性比较,差异无统计学意义(P>0.05)。结论螺旋CT三维重建技术对诊断复杂性肛瘘以及肛瘘分级有较高的准确性,同时可以明确肛瘘内口和瘘管的走行,有利于手术方案制定及实施,值得基层医院应用。Objective To explore the value of spiral CT three-dimensional reconstruction technique in the diagnosis of complex anal fistula in primary hospitals.Methods A total of 98 patients with complex anal fistula admitted to our hospital from June 2020 to June 2022 were selected.All patients were examined by MRI and spiral CT three-dimensional reconstruction technique.The surgical results were used as the gold standard to analyze the accuracy of spiral CT three-dimensional reconstruction technique in the diagnosis of complex anal fistula internal orifice and fistula and the accuracy of anal fistula classification.Result Of 98 patients were diagnosed with complex anal fistula during operation,including 51 cases of gradeⅠ,36 cases of gradeⅡand 11 cases of gradeⅢ,respectively.A total of 112 internal openings and 132 fistulas were found.The diagnostic accuracy of MRI and spiral CT three-dimensional reconstruction for complex anal fistula was 100.00%,and the accuracy of grading diagnosis was 98.98%and 96.94%,respectively;the diagnostic accuracy of internal orifice and fistula of anal fistula was 93.75%,96.21%and 91.96%,94.70%,respectively.With the surgical results as the gold standard,there was no significant difference in the accuracy of spiral CT three-dimensional reconstruction and MRI in the location of internal opening,fistula detection and grading diagnosis of complex anal fistula(P>0.05).Conclusion Spiral CT three-dimensional reconstruction technology has high accuracy in the diagnosis of complex anal fistula and anal fistula classification.At the same time,it can clarify the course of anal fistula and fistula,which is conducive to the formulation and implementation of surgical plans and is worthy of application in primary hospitals.
