Reviewer’ s report
Title: Gastric submucosal abscess caused by Edwardsiella tarda infection: a case report
Version: 2Date: 29 Aug 2020
Reviewer's report:The manuscript reports a patient with gastric submucosal abscess caused by Edwardsiella tarda
infection. The authors argue that EUS -guided drainage with antibiotic therapy might be effective
for treatment of gastric submucosal abscess.This case is interesting, but I have some comments.
My comments are as follows.
1)What is the route of E. tarda infection? Did the patient have any pets or ingest food containing E.tarda?2)Authors described "both blood and abscess cultures were positive for E. tarda" in the casepresentation section, but also described "blood culture and ascites revealed E. tarda" in thediscussion section. Which one is correct, abscess or ascites?3)Cholecystitis is more common in Japan as a primary disease of gastric wall abscess according tothe author's references. Did the patient have cholecystitis?4)Is E. tarda acid-tolerant organisms?5)After percutaneous drainage, the size of the gastric submucosal abscess was not changed. Howwas the symptom, leukocytosis and C-reactive protein level after percutaneous drainage?
I hope these comments will be helpful.
