Reviewer's report:  
 
This is a clinically relevant and interesting case study with potential to advance the management 
of food bolus obstruction. The following comments  and suggestions should improve the 
manuscript.  
1. Page 4, etc please spell dysmotility (not dismotility).  
2. Page 5, more details of the patient's history would be helpful if possible, such as the frequency 
of previous bolus impactions, and how recent, h ow many in past 12 months, etc.  
3. Page 6, lines 21 & 22 would read better as: "steakhouse syndrome" has infrequently been 
associated with esophageal motility disorders....  
4. Page 6, line 23: estimated incidence (not esteemed).  
5. Page 7, line 16: suggest ive of ... (rather than 'significant for').  
6. Page 8, line 10: was a safe ... (rather than 'represents' a safe ...). As this is a single case report, 
I believe it is important to be cautious with the wording here; I'm sure the authors would not 
wish to be  seen to be extrapolating too much to other patients without, as they acknowledge, 
further research and validation. Hence in line 12 I suggest it "may" be recommended (rather than 
"should" be ...).
