Title: Endoscopic ultrasonography guided cutting scar of esophageal stricture after endoscopic
injection sclerotherapy
Version: 0 Date: 30 Apr 2022
Reviewer's report:
The authors showed that endoscopic incision guided by ultrasonic endoscopy was effective for
esophageal stricture due to EIS. The treatment method was interesting. However, the study's
methodology was not explained enough, which is a critical issue. Furthermore, there were lots
of grammatical errors in this manuscript. I have raised the following questions.
1) What are the hypothesis and aim of this study? Please clarify them in the introduction.
2) Are there any previous reports that showed the efficacy of EUS guided stricture cutting? In
other words, what is the novel point of this study?
3) How did you evaluate dysphagia? Did you use a validated questionnaire?
Please show the degree of stricture after treatment.
4) Please clarify how to identify EIS scar by EUS in the method section.
5) How did the EUS findings guide the incision by dualknife?
Did you decide the length of incision or depth of incision depending on the EUS findings?
6) What is the reason you chose the subject treated by EIS? Why were patients with esophageal
strictures due to other reasons (e.g., ESD) not included?
7) Please specifically write the limitations of the study.
8) To conclude that the EUS guided endoscopic incision is effective, a comparison between the
endoscopic incision with the EUS guide and without it is needed.
9) Please add the figure showing the stricture improved by the treatment.
10) There are too many grammatical errors, and some sentences are difficult to understand.
Please check carefully and consider rewriting.
