Abstract:
Objective To establish a three-dimensional visualization model of complex anal fistula based on high-resolution mag-netic resonance imaging(HR-MRI),and to explore its feasibility and clinical application value.Methods The clinical and imaging data of 26 patients with complex anal fistula were analyzed retrospectively,and a three-dimensional visualization model based on HR-MRI images was established.The Parks typing,internal orifice,external orifice,branch fistula and abscess were evaluated by radiolo-gists and anorectal surgeons in HR-MRI images and the three-dimensional visualization model,and the SPSS 22.0 software was used to analyze the assessment results against the clinical surgery one by one.Results A total of 26 patients had 17 trans sphincteric fis-tulas,7 inter sphincteric fistulas,and 2 suprasphincteric fistulas,and the accuracy of Parks typing based on HR-MRI images and three-dimensional visualization model was 100％;26 patients had a total of 33 internal orifices,and the evaluation of internal orifices based on HR-MRI images was better than that of three-dimensional visualization model(P=0.180 vs P=0.022);15 patients had a total of 32 external orifices,and the evaluation of external orifices based on three-dimensional visualization model was better than that of HR-MRI images(P=0.791 vs P=0.049);20 patients had perianal abscesses,and the evaluations based on HR-MRI images and three-dimensional visualization model were both highly accurate(P=0.549 vs P=0.625);18 patients with branch fistula,the evaluation of branch fistula based on three-dimensional visualization model was significantly better than that of HR-MRI images(P=1.000 vs P＜0.001).Conclusion Based on three-dimensional visualization model of HR-MRI,the evaluation of complex anal fistula Parks typing,external orifice,branch fistula and abscess is more accurate,which is worthy of further research and promotion.
