- Endoanal ultrasound is also used intraoperatively to give surgeons more information at the time of examination with anesthesia.
- Accuracy of endoanal ultrasound can be improved by injection of hydrogen peroxide into fistula tracks.
- Ultrasound has a limited field of view (about 2 cm from the anal probe) and is poor at evaluating pathology beyond the sphincters (both laterally and above).
