[Retracted] The Value of Transrectal Ultrasound in the Preoperative Diagnosis of Complex Anal Fistula (CAF): Based on a Retrospective Cohort Study

<div>Ultrasonographic images of intraluminal rectal probe in typical cases. Note: (a) the echo of ≥2 fistulas can be seen, and the fistula passes above the deep part of the external sphincter; (b) the longitudinal section of the fistula shows a thin banded low echo, and the transverse section is round; (c) the echo of the branch can be seen between the fistulas; (d) strong echo gas shadow can be seen in the cavity. One end of the branch is blind, and the other is connected to the main tube.</div>
