gastritis cystica polyposa

Reviewer's report:
This is an interesting case report regarding a very rare condition: gastric cystica
polyposa. In this case report authors describe a case of a 53 year-old man who
underwent distal gastrectomy and visited the emergency department for
hematemesis. Endoscopic hemostasis and interventional radiology were
ineffective and the patient underwent partial resection of the anastomosis site.
However, there is a major comment:
Major Comment:
1. In the case presentation, authors asserted that "The bleeding subsided when
IVR was performed, and re-bleeding was not observed during the IVR procedure
although endoscopic stimulation was applied to the predicted bleeding site.
Based on the discussions among physicians, surgeons, and radiologists, surgical
treatment was necessary ". It appears from the description that IVR was
effective, so why was surgical treatment performed? In the abstract authors
asserted that patients was unresponsive to IVR, but it seems the opposite in the
case presentation. Please explain 
better this crucial point.
