Abstract

Objective: To analyze the effect of superficial high frequency ultrasound (HFUS) combined with transrectal ultrasound (ERUS) on the diagnostic accuracy of patients with perianal abscess. Methods: Sixty-three patients with perianal abscess were selected from June 2017 to August 2018. 48 cases of simple perianal abscess, 10 cases of anal fistula, and 5 cases of compound perianal abscess were confirmed by operation. Among them, 13 cases of perianal abscess were formed. There were 38 cases of perianal cyst formation and 12 cases of perianal abscess formation. The superficial HFUS, ERUS and superficial HFUS+ERUS tests were performed, and the accuracy of the above test methods was counted. Results: The accuracy of different types of perianal abscess was 92.06% higher than that of superficial HFUS 66.67% and ERUS 68.25% (P<0.05). The accuracy of combined diagnosis of perianal abscess in different periods was 90.48% higher than superficial HFUS 69.84%, ERUS 68.25 % was diagnosed alone (P < 0.05). Conclusion: The superficial HFUS combined with ERUS is applied to patients with perianal abscess, which can effectively improve the diagnostic accuracy and provide a scientific and reasonable reference and basis for clinical selection of surgical timing, planning of surgical procedures and observation of therapeutic effects.
