Title: Bilateral vocal cord paralysis after endoscopic placement of fully covered self-expandable metal
stent for palliative treatment of malignant proximal esophageal obstruction: two case reports
Version: 1 Date: 03 May 2020
Reviewer's report:
Thank you for the clarifications and the corrections. Only a few corrections remain which can be made
easily
1. In the title,use of the phrase "about two cases" somehow does not seem appropriate. "Two case
reports" should be sufficient, i think
2. In the conclusions part within the abstract, the sentence "this represents a diagnosis and therapeutic
emergency" is grammatically wrong and unnecessary.
3. Please change "well described in the literature"  to "well described in literature".
