Reviewer's report:
REVISION ASSESSMENT FROM THE ACADEMIC PEER REVIEWER: 
Has the author addressed your concerns sufficiently for you to now recommend
the work as a technically sound contribution? No
Reviewer comments: Thank you for the opportunity to review this revised
manuscript. 
The authors have detailed their responses to the original peer review comments
and have made efforts to improve the manuscript.
My comments are now mainly relating to style and wording:
1) The scientific content has been improved and the material broadened, in
addition to reformatting of the images. However, the way the case report is
approached in the write-up and in particular the wording of this would benefit
from further language review and potentially drafting assistance. The
background jumps straight in with little preamble to introduce the reader to the
topic or nature of the case report. The wording and word order is in places less
easy to understand.
2) Minor points regarding the title of the case report to help increase its
relevance and future use when the topic is being searched for a) good practice
would mean the title could include the words 'case report' to make it clear this is
the nature of the paper, and b) the authors might consider re-wording as per their
own summary at the end of the paper to make it clear that this EUS FNA is
helping diagnose UCC with duodenal metastases.
