Dear Sir  
 
 
 
The manuscript by Wetwittayakhlang et al. entitled "Re -bleeding and its predictors after capsule 
endoscopy in patients with obscure gastrointestinal bleeding in long -term follow -up" deals with a 
relevant problem faced in daily clinical pract ice. In fact, the re -bleeding after CE is crucial and 
every data about that are wellcome.  
 
 
Notably the authors find some clinical factor related to the rebleeding rate and stress the 
importance of enteroscopic intervention to reduce the probability of a se cond episode  
 
 
I think that the corrections of the previous referees and the answers improved the paper and 
clarfied all the concerns
