This is a nicely written paper about ERCP procedures safety for  elderly. The issue is becoming 
more and more important since number of elderly people is increasing and also the need for 
ERCP for them.  
The main problem with the study is that no deep sedation is used even if many of the patients 
were in poor condition. That, in my opinion, should not happen nowadays. If the paper is 
accepted for publication, this matter should be highlighted and discussed.  
- In background line 10 sphincterotomy word should be corrected  
- In chapter "ERCP: procedures, success rate and com plications" it is mentioned that in 22 
patients , cannulation was not successful.  They only give a reason for that for 6 out of 22
