Reviewer ’s report

abdominal pain

Reviewer’s report:  
 
The authors describe a case of ectopic pancreas in the ileum presenting as obscure 
gastrointestinal bleeding and episodes of abdominal pai n. The case is interesting, however, it's 
not the first one to report the association between gastrointestinal bleeding and ectopic pancreas 
located in the ileum. Besides, some points should be raised from the authors:  
 
--In abstract "59 -year-old man had 9 months history of intermittent melena", but in case 
presentation "A 59 -year-old man had 3 months history of intermittent melena", please clarify.  
 
-There are some spelling and grammatical mistakes in the manuscript, which needs correction.  
 
-The title is no t very suitable for this case, its scope is too broad and not attractive.  
 
-There are several case reports about obscure gastrointestinal bleeding caused by ectopic 
pancreas, such as Korean J Gastroenterol. 2013; 62(3):165 -8., Quant Imaging Med Surg.2015; 
5(5):783 -6. and Clin Endosc. 2012; 45(3):194 -7. These studies should be summarized and 
presented in the Discussion section.  
 
-Discussion should be enriched by discussing clinical presentation, investigations, treatment, 
prognosis and complications as availa ble in the literature about ectopic pancreas.
