As noted by R1, this is a widely known result. Please carefully address the need for this paper and what it adds to already published articles

The study design was professional and the article was well written.

The conclusion was widely known, and there were not enough new fundings for this area.
You included gastroduodenal artery aneurysm and excluded pancreatico-duodenal artery aneurysm, right?
I think there is a difference in the treatment outcomes of aneurysm between true aneurysm and pseudoaneurysm. How about these variables included in the outcome analyisis?
I think the variables need to be more clear
for example,
1) pancreatitis should be defined and divided into acute and chronic pancreatitis.
2) pancreatic obstruction --> pancreatic duct obstruction
3) vessel obstruction --> artery or vein obstruction
systemic review of previously published reports
I think TAE and percutaneous thrombin injection are similar treatment options even though the access is different.
Anyway GDAA are treated by endovascular means about 90%, which included TAE, stenting.
It is notable current trend of GDAA treatment.

Being part of the collateral networks between the celiac (CA) and superior mesenteric (SMA) territories, aneurysms of pancreaticoduodenal and sometimes gastroduodenal artery were reported to be closely associated with concomitant stenotic/occlusive lesion of either CA or SMA. Embolization of GDAA in such cases may have to deal with the risk of visceral ischemia due to loss of vital collateral blood perfusion. Please address whether in this systemic review the presence of GDAAs were found to be related to concomitant CA/SMA lesion. Or, alternatively, please justify the decision not to include concomitant stenotic/occlusive lesion of either CA or SMA as one of the predisposing factors.
Nearly all the percentages of "TAE%", "surgery%", and "observation%" in the Tables do not add up to 100%, please clarify.
In the Discussion part, the authors should acknowledge the potential survivorship bias in the case reports.
