Title: Large common bile duct stones in high-risk elderly patients: Immediate endoscopic stone
removal or elective stone removal? A single-center retrospective study
Version: 1 Date: 26 Aug 2023
Reviewer's report:
This is a very well-written study and the details are nicely described.
I believe this paper is worthy of publication after addressing the following issues:
1.  The cannulation techniques are described in the methods section but not detailed in the
results section.  For example, how many patients needed advanced techniques in each group,
e.g. double-wire techniques.  This might affect the adverse events for each group.
2.  The table lists that about 70% had native papillae.  Only the patients with native papillae
should be included in the study.  Those with prior interventions should not be included.
3.  While the stone clearance rate is higher in the delayed group, the number of ERCPs required
for each group to achieve stone clearance should be detailed.
