hernia in an adult male- a case report

Reviewer's report:
The authors presented a case report of a patient with isolated dextrogastria with
eventration of right hemidiaphragm. Type 2 isolated dextrogastria is rare and the
report of it is informative for clinicians to consider differential diagnosis for
patients with abdominal pain or vomiting. 
However, I think the abnormal findings of chest X-ray can lead clinicians to
perform further diagnostic examinations including CT scan. Therefore, the
diagnosis of dextrogastria might not be so difficult. It should be better to describe
future perspectives of the disease including novel diagnostic features or
therapeutic challenges in case report.
Major comments:
1. Please clarify about the treatment of isolated dextrogastria more in detail. In
this case, patient was not performed specific treatment for dextrogastria and
improved his symptoms. Which therapy was considered to be effective,
antibiotics, proton pump inhibitors, or others? 
Was there any possibility that the causes of symptoms were due to not only
dextrogastria but also other etiology such as acute gastritis or functional
dyspepsia? 
2. When recurrence of symptom occurs, should patient have any surgery or other
therapies?
Please discuss the indication or selection of therapy for patients with isolated
dextrogastria in discussion section.
Minor comments:
1. In conclusion, authors should state their conclusion briefly. The first part in
the section of conclusion should be written in discussion section.
