造影CT三维成像在肛瘘术前诊治中的应用

Application of Three-dimensional Imaging of Contrast CT in Preoperative Diagnosis and Treatment of Anal Fistula

目的观察造影CT三维成像在肛瘘术前诊治中的应用价值。方法对42例疑似肛瘘患者的临床资料进行回顾性分析。均于术前行瘘管造影CT平扫及三维重建,根据手术结果评估造影CT三维成像对肛瘘的诊断效能。结果肛肠专科体检对肛瘘分类诊断与手术结果符合率为59.52%显著低于造影CT三维成像与手术结果符合率100%(P<0.05)。造影CT三维成像对肛瘘分型诊断与手术结果符合率为90.48%。造影CT三维成像对肛瘘内口、支管和脓肿的术前诊断准确度分别为63.89%、89.47%、100%。结论造影CT三维成像在对肛瘘分类、分型及对肛瘘内口、支管和脓肿等方面术前诊断效果良好,对指导手术治疗有重要意义。

Objective To observe the application value of three-dimensional imaging of contrast CT in preoperative diagnosis and treatment of anal fistula. Methods The clinical data of 42 patients with suspected anal fistula were retrospectively analyzed. All patients were given fistulography CT plain scan and three-dimensional reconstruction before operation. The diagnostic efficacy of three-dimensional imaging of contrast CT in the diagnosis of anal fistula was evaluated. Results The coincidence rate of classification diagnosis of anal fistula and surgical results in anorectal physical examination was significantly lower than that of the three-dimensional imaging of contrast CT and surgical results(59.52% vs 100%)(P<0.05). The coincidence rate of classification diagnosis of anal fistula and surgical results was 90.48% in three-dimensional imaging of contrast CT.The preoperative diagnostic accuracies of three-dimensional imaging of contrast CT on the internal fistula, branches and abscess were 63.89%, 89.47% and 100% respectively.Conclusion Three-dimensional imaging of contrast CT has good preoperative diagnosis effects on the types and classification of anal fistula and the internal fistula, branches and abscess. And it has important significance in guiding surgical treatment.
