Title: Title # Endoscopic nasobiliary drainage-based saline-injection ultrasound: an  imaging
technique for remnant stone detection after retrograde cholangiopancreatography
Version: 4 Date: 10 Oct 2021
Reviewer's report:
hank you for opportunity of revised manuscript, the tile of “Endoscopic nasobiliary drainage-
based saline-injection ultrasound: an imaging technique for remnant stone detection after
retrograde cholangiopancreatography”. Authors described the usefulness of US examination
using ENBD tube saline injection. Although the exam of US with ENBD tube saline injection
were useful, authors couldn’t answer reviewer comments well. For example, author defined that
only stones larger than 5 mm are considered to be meaningful. If authors couldn’t analyze the
data excluding debris, authors should compare the detection rate of CBD stone with and without
using ML. The response for major 1 is also insufficient. Unfortunately, the contents of the article
were similar to previous report and generally it is difficult to understand the images and tables.
