Title: Endoscopic ultrasonography guided cutting scar of esophageal stricture after endoscopic
injection sclerotherapy
Version: 0 Date: 12 Apr 2022
Reviewer's report:
In this article, the authors investigate the efficacy and safety of EUS guided cutting scar of
esophageal stricture after EIS. It is a challenging and interesting report. However, there are
some concerns about this article. 1. The tile could be EUS guided cutting scar of esophageal
stricture after EIS. 2. Objectiinve could be "To investigate efficacy and safety of EUS guiding
to cut scar of esophageal stricture after EIS. " 3. In the Methods, the authors did not present
the brand name of dualkife and the mode in case of using the knife. ( e.g. endocut 100W).  In
addition, the authors did not explain the procedures enough. 4. To screen the residual varices,
the authors could use the doppler EUS. It may be a dangerous method without using the doppler
method. 5. The authors should explain what is Stooler classification in the article. 6. The authors
should present the exact data(e.g., EF<50 %) in the exclusion criteria.7. Did the authors confirm
the scar lesion exactly? Please present the examples of one to twelve o'clock scars. 8. Most
cases are HBV patitents. Please explain the reasons. 9. In the table, please add the units of EIS
and ballooning time. 10. The endoscopic images are poor focus and have no arrows. 11. In
Conclusion, the sentences " This study ~" should be in the Dissccuion. 12. Extensive English
editing is necessary. 13. In conclusion, this study is interesting; however, the authors should
carefully consider this method's indication due to the risk of bleeding and perforation. It might
present a dangerous take-home message.
