Reviewer’s report:  
 
Abstract - 
 
1"(also referred to as heterotopic pancreas, pancreatic heterotopia, accessory pancreas, aberrant 
pancreas, or pancreatic rest)" is repeated both in abstract and  the main text. The same can be 
omitted from the abstract to make the crisp and abstract like.  
 
2.Line 20 "low hemoglobin level, i.e. 109 g/L (10.9 g/dL)" one cane be omitted. Just 10.9 G/dL 
will suffice.  
 
3. line 23   "Large" must be followed by its size, i t could have been measured and written the 
size with the marking at least in one image.  
 
4. Line 27 "involving muscular layer" . Which muscle layer, muscularis mucosae, circular  or 
longitudinal needs to be mentioned and same to be marked on histological im age. When the post 
polypectomy image is   not in consonance with the description.  
 
5 page 27 -28- Only one arrow in the image two picture low and high power microscopic view.  
 
The muscle layer in a pedunculated polyp whereis nor marked on histology  
 
6.Conclusi on. Same as last conclusion - abstract conclusion can be short.  
 
Our case report reveals very rare cause of obscure gastrointestinal bleeding accompanied with 
episodes of abdominal pain - an ectopic pancreas located in ileum. Although ileal polyp was 
located  by magnetic resonance enterography and later by retrograde enteroscopy, diagnosis of 
ectopic pancreas could not be made until polypectomy and histopathological examination  
  
7.Key wards - Perfect  
 
Main Text - 
 
8 line 17 -- Suggested "recurrent"   to obscured GI bleed to be added.  
 
9. Line 37 - He had pain at left upper abdominal pain but the lesion is located at right lower part 
on MR study. The authors have no explained the diagonally opposite finding. Needs expla nation.  
A mention no lump was palpable will be appropriate.  
 
10 Line 40 Haemoglobin in L or dL as mentioned point two. How ever  I do not have any serious 
objection  
 
11. The polyp size is changing in size. MRI, Enteroscopy and biopsy specimen.  So MR 
measur ed size will be better and other part of the text only polyp is suggested.  
 
12. Page -4 --20 CC adrenalin saline injected. Looks a large volume for small bowel. The image 
B is not showing the same. Please reconcile.  
 
13. Images are the brain and heart of case  reports.  Enteroscopic view are the real images in this 
case.. The author should have given few more images. At least one more view showing the 
pedicle with the endo -loop have been most appropriate.  
 
Discussion - It is written well. Two aspect needed high l ight. One the location of ectopic 
pancreatic tissue in terms of which layer of the small bowel. And the second is the ectopic  
pancreas tissue and bleeding.
