case report and literature review
Version: 
0 
Date: 
24 Jun 2021
Reviewer's report:
In case report, the author shown the only reported case with gastric outlet
obstruction secondary to gastroduodenal IgG4-RD. This case was confirmed to
be IgG4-RD after WIPPLE surgery. IgG4- Related Disease is indeed a Rare
Cause of Gastric Outlet Obstruction.
The authors could further improve the manuscript by addressing the following:
1.     After reviewing the literature, the author should put forward his own
suggestions: (1) If there are patients with unexplained duodenal stricture, gastric
outlet obstruction or gastrointestinal ulceration, what tests and examinations
should be performed to further exclude IgG4-RD; (2) What are the
recommended treatments for IgG4?
2.     How is the prognosis of patients with IgG4 disease? Is surgery the
recommended treatment, especially the WIPPLE surgery?
