Title: Primary isolated asymptomatic gastric tuberculosis of the cardia mimicking gastric stromal
tumor: a rare case report and literature review
Version: 0Date: 06 Jan 2020
Reviewer: Michael J. Bartel
Reviewer's report:
I read the case report with interest submitted by Dr Lv and colleagues delineating a case of gastric
tuberculosis.This is an interesting case report of a rare condition and a well-donemanuscript.Suggestions:1.Abstract-Add to abstract that the lesion was seen in layer 4 / muscularispropria 2.Background-Would rephrase the 2nd sentence to caner or lymphoma endoscopically"-The sentence "gastric tuberculosis occurs in the cardia" needs to be rephrase and please add thecitations 3.Case presentationLine 58, 59. Would add "muscularis propra" as explanation of the 4thlayerAnd would rephrase "uneven internal echo" to heterogeneous echoSuggest also that theauthors comment why they opted to do an ESD of a tumor in layer 4. It has been reported howeverit is still (in the US) quite uncommon. Is that commonly done by the authors and maybe theirstandard of practice? Also the "negative rolling sign" suggests a deeper invasion. Why was no fineneedle aspiration done?4.Discussion-There is quite some repetition / redundancy particularly inthe lines 105-122. Suggest to shorten substantially.
