Reviewer's report:
I enjoyed reading this study entitled “Endoscopic nasobiliary drainage-based saline-
injection ultrasound: a novel imaging technique for remnant stone detection after retrograde
cholangiopancreatography”.
This study is interesting to show the efficacy of ENBD saline-injection US to detect remnant
stones.
However, there are some concerns about this study. The following comments should be
addressed.
#In Table 1-3, no unit were listed.
