Reviewer’s report
Title: 
A surgically treated case of severe upper gastrointestinal hemorrhage with
gastritis cystica polyposa
Version: 
0 
Date: 
15 Oct 2020
Reviewer's report:
This case presented severe gastric bleeding from GCP which could not be
controlled by endoscopic hemostasis or IVR and surgical resection was needed.
Although this is a rare and an interesting case, I have some comments.
This patients had been taking steroids for a long time. The author should
discuss about the effect of steroids on the bleeding.
After endoscopic hemostasis by clipping, when was the repeated endoscopy
performed? On the same day of hemostasis?
"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" means that the bleeding was stopped
spontaneously when the IVR was about to be started? Was the IVR difficult to
perform because the bleeding was stopped spontaneously and the bleeding cite
became unclear? If so, I cannot understand why surgical resection was performed
soon. In general, surgical resection is considered when the bleeding is recurrent
and difficult to control by endoscopic hemostasis or IVR.
In Table 1, hemostasis via surgery was performed in four cases. In these cases,
was an endoscopic hemostasis tried at first? How many cases were reported in
which the bleeding was difficult to control by endoscopic hemostasis at first and
was controlled by surgical resection?
