Research On The Application Of MRI In Clinical Diagnosis Of High Anal Fistula

Objective:To observe the consistency of high anal fistula clinical symptoms and signs, MRI examination and operation results, propose objective index for the diagnosis of high anal fistula, and to observe the relationship with perianal muscles.Methods:the operation as golden standard, the accuracy of diagnosis, clinical signs of MRI in the diagnosis of high anal fistula, the detection of primary in the mouth, secondary internal opening results; the range and degree of statistical anal ring hardening; according to MRI findings of statistical anal muscle and scope of high anal fistula involving the statistical high anal fistula; Parks and MRI classification; statistics of high anal fistula incidence of men and women; the results using SPSS17.0statistical software for χ2test and Fisher exact probability analysis method, according to the P<0.05standards considered statistically significant differences.Results:there was no significant difference in clinical diagnosis, MRI in the diagnosis of high anal fistula, the detection of primary in the mouth, in the mouth of the secondary results; high anal fistula after primary inner mouth; constituent ratio had no difference in anorectal ring stiffness; high anal fistula Parks typing to transsphincteric fistula, MRI type4and type5; high anal fistula incidence in male was higher than that of women.Conclusion:the clinical signs and MRI examination in the diagnosis of high anal fistula results no differences, the preoperative MRI examination can make the patients fully understand the relationship of fistula and perianal muscles and perianal clearance.
