Overview
Endoanal ultrasound used to know details of fistula anatomy, tracks, and the spinchters.This is used intraoperatively by surgeons to have better information of fistula. Accuracy of endoanal ultrasound is improved by injection of hydrogen peroxide into fistula tracks. Ultrasound has a limited use because probe can go 2 cm from the anus so it is poor at evaluating pathology beyond the sphincters.
Ultrasound
Endoanal ultrasound is cheaper but radiologist dependent modality.
- It is used to know details of fistula anatomy, tracks, and the sphincters.
- Endoanal ultrasound is also used intraoperatively to give surgeons more information at the time of examination with anesthesia.
- Accuracy of endoanal ultrasound is improved by injection of hydrogen peroxide into fistula tracks.
- Ultrasound has a limited use because probe can go 2 cm from the anus so it is poor at evaluating pathology beyond the sphincters (both laterally and above).[1][2][3]
