Two-finger digital rectal examination for the diagnosis of anal fistula: protocol for a randomized controlled trial.

ABSTRACT:

Background

Anal fistula is an anorectal infectious disease caused by a perianal abscess or perianal disease. Accurate anorectal examinations are of great significance. The two-finger digital rectal examination (TF-DRE) has been used in clinical practice, with a lack of comprehensive research on the value of the TF-DRE in the diagnosis of anal fistula. This study will compare the difference in the diagnostic value of the TF-DRE, traditional digital rectal examination (DRE), and anorectal ultrasonography in the diagnosis of anal fistula.

Methods

For patients who meet the inclusion criteria, a TF-DRE will be performed to explore the number and location of the external and internal orifices, the number of fistulas, and the relationship between the fistula and the perianal sphinc
