Reviewer's report:
Thank you for giving me an opportunity to review this article. I can read your paper with
great interest. In recent years, the results of treatment for pancreaticobiliary malignancies have
been improving, and the number of cases detected at an early stage has been increasing.
Therefore, patients who have undergone pancreaticoduodenectomy and choledochojejunostomy
are increasingly surviving long term after surgery. In such long-term survivors, cholangitis due
to CJS is an important problem that significantly interferes with the patient's quality of life. BE-
ERCP in patients with CJS is indeed a very beneficial treatment. However, even after technically
successful treatment, stenosis may recur.
I have some comments regarding the manuscript.
Comments
#1
The authors discussed the usefulness of interventional EUS in patients with CJS. Therefore,
please provide the percentage of cases in which interventional EUS was performed to treat CJS
during the current study period, if any. Do the authors give priority to BE-ERCP or interventional
EUS in patients with CJS? If necessary, modify the figure 3 (patients flow).
#2
I would like to know what rescue treatment was provided for the three cases of technical failure.
#3
The number of stenosis recurrences in the present study was 12. I would like to know more
about the clinical course of these 12 cases. It seems that there were cases in which metallic stents
were placed, but were finally the stents removed in all cases? Or are there cases where the stents
(plastic or metallic) were periodically replaced? Please describe these 12 cases of restenosis in
more detail in the Result/Discussion section.
