Reviewer's report:  
 
The authors tried to introduce the usability of novel technique for repositioning a nasobiliary 
catheter from the mouth to nostril. Though this novel technique is very interesting, this study has 
some problem. The authors should clarify the following point s.   
 
 
1. Though I understand this study is retrospective fashion, it is necessary to explain how the 
patient was allocated (depend on time? operator? facility?)?  
 
 
2. Page 8, line 10: "Patients without sufficient~", how many patients were excluded? The 
authors should clarify the number of patients who were excluded in this study in each 
group.  
 
 
3. Page 9, line 42; "mean ± SDs", Were all continuous variables normally distributed? If 
not, continuous variables should be presented "median (range)". If continuous variables 
were normally distributed, t -test should be used.  
 
 
4. Page 10, line 35; I cannot understand the reason why difficult to use the new technique in 
two patients, anatomical reason? Please make it clear. How about Mallampati score of 
this two patient s?  How to tube reposition in this two patients?    
 
 
5. Page 11, line 53; "Appropriate depth", how to decide the "appropriate depth"?  
 
 
6. Page 13, line 21; Was this study approved by Ethics Committiee of each institutes?
