Abstract:
Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.
