Title: Three-dimensional pelvic ultrasound is a practical tool for the assessment of anal fistula
Version: 3 Date: 11 Dec 2022
Reviewer's report:
The presented manuscript describes usefulness of the pelvic three-dimensional(3D) US for
assessing anal fistula. Pelvic ultrasonography is noninvasive, and if it can be proven to be
equivalent to MRI in positive results, it would be a great benefit to patients and to society.
However it requires some revisions as listed below.
1. The authors need to describe the indications for surgery in this study
2. How many experts performed the echo?  How many years has the expert been performing
echoes?  The authors are recommended to give detrails about the experts.
3. The authors are requested to define Accuracy rate.
