PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: The authors report an interesting technique to
achieve luminal patency in a patient with oesophageal stricture following surgery
for atresia. The approach is novel and provides several benefits. It will be of
interest to the readership of the journal.
REQUESTED REVISIONS: 
General comments-
Referencing - use either superscripted numbers or numbers within brackets. The
current use of superscript numbers with a single bracket is unconventional.
Specific comments
P7 L2 - Repeated balloon dilation - why would repeated dilation be performed
for suture leakage?
P7 L4 - Anal lumen- Do you mean the lumen at the caudal end? The use of the
word "anal" to indicate the caudal end is confusing in this sentence.
P8 L15 - Severe stricture - use either "a severe stricture" or "severe strictures"
P9 L3 - Thick stricture site - I don't understand the expression, are you referring
to the thickness of the wall at the level of the stricture
Figure legends - "distant range", "close range" - do you mean the view from a
distant?
ADDITIONAL REQUESTS/SUGGESTIONS: 
Referencing - use either superscripted numbers or numbers within brackets. The
current use of superscript numbers with a single bracket is unconventional.
Please use words that are unambigous. Certain words (e.g. anal) when discussing
the anatomy may have multiple meanings.
