Title: Clinical outcomes of endoscopic removal of foreign bodies from the upper gastrointestinal
tract
Version: 1 Date: 27 Jul 2021

Reviewer's report:
Dear Authors,
I have read with interest the enclosed manuscript dealing with endoscopic management of
foreign body ingestion in adult patients.
I found several issues that should be addressed in order to increase the overall quality of your
manuscript.
- The study included only adult (> 18-year-old) patients. I suggest to clearly state this choice
in the text and abstract.
- The introduction and discussion should refer to the most updated guidelines (ESGE and ASGE
at least)
- risk factors for adverse events included patients' age, foreign bodies' size and shape, and
impaction time. It is not clearly stated in the text if the authors tested also the location of foreign
body impaction (esophagus vs. stomach. vs. duodenum). I suggest to include this variable in the
univariate and multivariate analysis.
- I suggest assessing wheater airways intubation, overtube or transparent hood have a protective
role for adverse event.
- In the final paragraph of the conclusion, the Authors state "In addition, endoscopic procedures
in elderly patients and those with sharp foreign bodies may prevent adverse events." I failed to
understand if this sentence is supported by study results.
