Title: Role of endoscopic ultrasonography for differential diagnosis of upper gastrointestinal
submucosal lesions
Version: 0 Date: 10 Jul 2021
Reviewer's report:
The article is a well written retrospective study on EUS based SMLs assessment. However this
just does not add anything to current knowledge.
According to author report, the only news
would be this:  "Additionally, the maximum diameters of the lesions were compared and the
results suggested that the mean maximum diameter of stromal tumors was significantly greater
than that of leiomyomas. This may provide a certain reference for differentiation between the
two types of SMLs "
Comparing the size of leiomiomas and GIST as a discriminating feature is misleading
considering the first are mostly esophageal and the second were mainly gastric. Esophageal
lesions are likely to cause early symptoms compared to gastric lesions being investigated and
diagnosed earlier. It is a matter of location more than size.
A part from the clearly misleading statment on lesion size in suggesting one etiology more than
the other, all other conclusions are already well known. I would at least expect info on contrast,
elastography, needles... maybe that could have been more interesting.
