Title:Acetic acid - indigo carmine chromoendoscopy for delineating early gastric
cancers: its usefulness according to the histologic type
Version: 1Date:12 December 2009
Reviewer: Ralf Jakobs
Reviewer's report:
Major compulsory revisisons: none
Minor essentials revision:
This is a well-defined report on the use of a special technique of
chromoendoscopy combininy acetic acid and indigocarmine for the delineation of
early gastric cancers.
Methods used are appropriate but authors should more clarify the technical
details (e.g., concentration of inidigo carmine solution, volume of solution used
for chromoendoscopy; type of catheter).
Data seem to be valid and sound and the manuscript is adhering to relevant
standards for reporting.
The discussion is focused on chromoendoscopy. In the past two years all of the
major endoscopy manufacturers have brought new “virtual “ techniques (e.g.,
NBI, FICE, I-SCAN) on the market and all are equipped with high resolution
video techniques like HDTV-standard. Author should therefore discuss their
results in comparison to the meanwhile published reports comparing
chromoendoscopy with virtual techniques.
Finally, the authors clearly acknowlegdge any work upon which they are building,
the abstract is addressing the content of the study and the writing is acceptable.
Level of interest: An article of importance in its field
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a
statistician.
Declaration of competing interests:
I declare that I have no competing interests.
