Abstract
Objective: To discuss the diagnostic value of ultrasonography in perianal abscess and anal fistula. Method: through retrospectively analyzing clinical data of 80 cases of perianal abscess and anal fistula patients in our hospital from January 2010 to December 2011, compare the sensitivity (Se), specificity (Sp) and positive predictive value of transrectal ultrasonography and body surface ultrasonography. Results: Operation pathology of 80 cases of patients confirms that there are 35 cases of single perianal abscess (43.8%), transrectal ultrasonography and body surface ultrasonography diagnosis also confirm 35 cases; 2 cases of single anal fistula (2.5%), transrectal ultrasonography and body surface ultrasonography diagnosis also confirm 2 cases; 43 cases of abscess combined anal fistula (53.8%), body surface ultrasonography diagnosis confirms 39 cases of abscess and 36 cases of anal fistula transrectal ultrasonography diagnosis confirms 40 cases of abscess and 38 cases of anal fistula. There is no significant difference in Se, Sp and positive predictive value between two groups (p > 0.05). Conclusion: There is no significant difference in Se, Sp and positive predictive value of body surface ultrasonography diagnosis, but it can obviously relieve patients' pain.References
