Reviewer's report:  
 
This cas e report give us a good education that doctors should be aware of possible ZES in 
patients with refractory peptic ulcers and severe GERD for a long time. In MEN1/ZES, severe 
eosphagitis with stricture can occur in 5 -10% patients. Endocopic balloon dilation  for treating 
benign esophageal stricture is also not a news. The more interest in this case is about treatments 
of MEN1/ZES. Though the pancreatic neuroendocrine tumor with weakly positive immunostain 
of gastrin was found in this case. It is not represent ed that the symptoms of ZES in this case was 
related to p -NET other than duodenal NET because most of p -NET in MEN -I is non -functional. 
Therefore, the treatment about this patient should be discussed into two directions. One is 
medical treatment. Due to mo re benign course and multiple lesions of MEN1/ZES, medical 
treatment for inhibiting acid to control symptoms is more important than surgery. So, the author 
should give us information about the medical treatment (like PPI dose and duration) before 
surgical and endocopic treatment. The second point is about surgery in MEN1/ZES. When to 
receive surgery and what kind of surgical method (local resection or pancreatoduodenectomy) is 
still unknown, so the author can disccus more detail about the decision of 
pancre atodudenectomy. Finally, i think this case give us the opinion that endoscopic dilation for 
treating esophageal stricture is useful after acid control in MEN1/ZES, but the need of 
combination of surgery is still under investigation.
