Reviewer’s report:  
 
This is an interesting case of a large Brunner's glang harmatoma  being treated as a pedunculated 
polyp with hard snare polypecto my. The authors concluded that the pedunculated large Brunner's 
glang harmatoma can be hard snare polypectomy with good safety.  
 
 
Major issues:  
 
Several reports disscues about the endoscopi c and surgical treatment for large Brunner's glang 
harmatoma. The recent work added few new information. They authors need to perform minimal 
review and disscue the difference between two methods ( including clinical outcomes, advance 
events, indications, and contraindications). How to determinate the right methods for the 
patients?  They need to summarize as a Table and updated the new reports as the report  of 
Frenkel (Hindawi Case Reports in Surgery Volume 2017, Article ID 6940649, 7 pages

In the past, the terms Brunner gland hyperplasia, Brunner gland hamartoma, and Brunner gland 
adenoma have been used interchangeably causing some confusion in the pathologic classification 
of these lesions.Brunner gland hyperplastic  polyps are usually small (0.5 cm -1.5 cm), 
asymptomatic, and discovered incidentally during upper endoscopy performed for other reasons. 
Brunner gland hamartomas are larger (.2 cm), and when symptomatic, present as gastrointestinal 
(GI) hemorrhage or intes tinal obstruction, often requiring endoscopic or surgical resection.The 
concept of Brunner gland adenoma is very contro - versial and still a matter of ongoing debate.In 
fact, prior reports of several large Brunner gland proliferative lesions without defini tive evidence 
of cytologic atypia that were reported as Brunner gland adenomas,5,7 in retrospect, represent 
examples of Brunner gland hyperplastic polyps or Brunner gland hamartomas. Brunner gland 
hyperplastic nodules/polyps and Brunner gland hamartomas ar e now believed to represent a 
morphologic continuum of benign hyperplastic/proliferative lesions of Brunner glands. As such, 
the term Brunner gland hyperplasia/hamartoma has been proposed for describing these 
nonneoplastic lesions.(Arch Pathol Lab Med. 201 9;143:370 -385; doi: 10.5858/ arpa.2018 -0034 -
RA) The authors need to check this with their pathologist.  
 
The authors believe that the endoscopic resection should been much safer if they  had performed 
a EUS(page 5 line 23 -25). Why ? The authors need to disc uss the importance of EUS.
