Reviewer’s report
Title: 
May chronic cough in chronic obstructive pulmonary disease be a
contraindication of Percutaneous Endoscopic Gastrostomy placement: a case
report
Version: 
4 
Date: 
19 May 2020
Reviewer's report:
This is a fluently written report on a case of interest to surgeons and
gastroenterologists.
I do agree with the authors conclusion.
I have three questions that I suggest the authors to address:
1) The details of the PEG method used in this report is missing. The PEG can be
performed by a pull or push technique. Was there an endoscopic control at the
end of the operative intervention? Were the operating surgeons sure that the
gastric part of the PEG tube was inside the stomach?
2) Complications occurring within 30 days are usually classified as operative
complications, according to Clavian Dindo. Was the complication a
postoperative complication or due the patient's pulmonary problem only?
3) Why was the second operative intervention conducted by the same method as
the first? Was there any discussion on using open or laparoscopy assisted
methods instead?
Are the methods appropriate and well described?
If not, please specify what is required in your comments to the authors.
No
Does the work include the necessary controls?
If not, please specify which controls are required in your comments to the
authors.
No
Are the conclusions drawn adequately supported by the data shown?
If not, please explain in your comments to the authors.
Yes
Are you able to assess any statistics in the manuscript or would you
recommend an additional statistical review?
If an additional statistical review is recommended, please specify what aspects
require further assessment in your comments to the editors.
