Title: The endoscopic ultrasound probe findings in prediction of esophageal variceal recurrence 
after endoscopic variceal eradication therapies in cirrhotic patients: A cohort prospective stud y 
Version: 0 Date: 23 Dec 201 8   
Reviewer:  Chen Shuan Chung  
Reviewer's report:  
The aim of this study was to evaluate the endoscopic ultrasound features in the prediction of 
recurrence of esophageal varices following endoscopic eradication in a prospective cohort. It is 
an interesting retrospective study, but some revisions are sugges ted before consideration for 
publication in the journal BMC Gastroenterology.  
 
1. Page 4, line 22: "...as soon as early intervention treatment possible in order to prevention 
esophageal variceal rebleeding" => should be in order to "prevent", not "prevent ion" 
2. This study defined eradication of EV as endoscopic normal esophageal mucosa or lesions 
lack a varicose appearance. Why not use EUP after endoscopic treatment to define 
eradication ? Because it would be "residual" rather than recurrence of EV after 
endoscopic treatment.  
3. Why use the cut -off value "14" for Child -Pugh score as one of the exclusion criteria?  
4. What was the timing and surveillance period of EUP after endoscopic eradication ?
