Title: Title # Endoscopic nasobiliary drainage-based saline-injection ultrasound: an  imaging
technique for remnant stone detection after retrograde cholangiopancreatography
Version: 6 Date: 26 May 2022
Reviewer's report:
In clinical practice, ML is often used for treatment of bile duct stones.
Thus, authors should not exclude the cases with ML in this study.
I mentioned that the author needs to distinguish between stone and debris, and analyze the data
which excluding debris at the CBD if possible.
If authors couldn’t analyze the data neither excluding debris or comparing the detection rate of
CBD stone with or without using ML, previous form including cases with using ML (revised 1
data)  was considered as suitable data for this article.
Thank you for your effort.
