Reviewer’s report
Title:

choledocholithiasis patients with a negative computed tomography
Version: 
2 
Date: 
21 Jan 2022
Reviewer's report:
1. Most comments were replied well. 
2. Author revised discussion section (page 14 line 2-16) for explaining high
adverse event in this study. Since aim of this study is to elucidate EUS-first
strategy in high-probability choledocholithiasis patients. I suggest to shorten the
length of this section.
