 3. Line 120 what do you mean by "disposable"  
 
Are you using dissolvable clips or the routine metal clips?  
 
 4. Line 109 why not add the phrase " which is at the end of the TET which will be the most 
proximal s ite in the colon" after the word "station"  
 
 5. Line 146 -147 should you refer to the literature report by Long C et al in your response #13 to 
my prior review?  
 
6. Line 237 do you mean " There was no tube obstruction when the tube was flushed actively 
after administration of the drugs or the microbiota/FMT solutions" this is worded better
