Reviewer’s report
Title: Needle tract seeding recurrence of pancreatic cancer in the gastric wall with paragastric lymph
node metastasis after endoscopic ultrasound-guided fine needle aspiration followed by pancreatectomy:
a case report and literature review.
Version: 0 Date: 05 Dec 2019
Reviewer: Kosuke Minaga
Reviewer's report:
The authors described a case of needle tract seeding after EUS-FNA for pancreatic cancer. The case
was intereting. I have some concerns regarding this manuscript.
1.  Was a pancreatic tumor invading the stomach on a preoperative CT image of pancreatic cancer? In
the CT image of Fig.1, the tumor of the pancreatic body and the stomach wall were very close, and the
possibility of direct invasion cannot be denied.
2. Please describe the product name of the EUS-FNA needle used for the diagnosis of the pancreatic
cancer.
3.  English  grammar  of  the  abstract  is  incorrect  in  several  places  and  should  be  submitted  for
proofreading.
Are the methods appropriate and well described?
If not, please specify what is required in your comments to the authors.
