Reviewer ’s report  
 
Title: Therapeutic outcomes of endoscopic papillectomy for ampullary neoplasms: retrospective  
analysis of a multicenter study  
 
Version: 0 Date: 14 Feb 2017  
 
Reviewer: Gian Luca Baiocchi  
 
Reviewer's report:  
 
The main take -home messages are: 1) complication and mortality after endoscopic papillectomy 
should be taken into account/ 2) overall success rate is not 100%. thus, I would expect that 
patients with poorer general conditions are the mos t interested for this technique. Would You 
comment? Or You consider the first endoscopic approach such as a "diagnostic rather that a 
therapeutic passage?
