Reviewer’s report
Title: 
Submucosal oesophageal squamous cell carcinoma with lymph node
metastasis: A case report and literature review
Version: 
0 
Date:

Reviewer's report:
This is an interesting case of complex management of a rare presentation of
esophageal SCC that was ablated with ESD and further chemptherapy. 
To improve the paper quality may I recommend some learning notes to be
included in the discussion part:
A- Essence of resection of SEL : size , symptom , etc
B- Possibility of pre-operative staging including CT guided lymph node biopsy
C- Pre-oerative versus post operative chemo-radiotherapy in ESD candidates
