Abstract:
Objective To evaluate the value of spiral CT volume reconstruetion(VR) technique in high complex anal fistula fistulography. Methods To analyze retrospectively internal openings and secondary tracts of 35 eases with high complex anal fistula verified by operation and follow-up above 3 months with VR,and compared with operation and outcome of follow-up. Results In 35 eases with high complex anal fistula, for detection of the presence of internal openings ,VR has a sensitivity of 72.7% ,a specificity of 100% ,a accuracy of 74.3% ,a positive predictive value of 100% ,and a negative predictive value of 18.1%. Secondary tracts have a sensitivity of 93.8% ,a specificity of 100.0% ,a accuracy of 94.6% ,a positive predictive value of 100.0% ,and a negative predictive value of 72.7%. Conclusion VR can demonstrate the 3D shape of fistula and is reliable in the diagnosis of internal openings and sec-ondary ducts, and is very valuable in the analysis of high complex anal fistula fistulography.
