The authors describe their experience of EUS-FNA of pancreatic cysts with
diameters ≤ 3 cm. Although interesting, there are some points that need to be
clarified. 
MAJOR POINTS
1. Did EUS-FNA results significantly change the clinical decision of these
patients? To answer this question, clinical characteristics prior to EUS-FNA
such as CT/MRI findings, serum tumor markers, etc, must be described.
Although the cyst diameters were ≤ 3 cm, if patients already had high-risk or
worrisome features, then EUS-FNA would not have been necessary.
2. In addition to comment 1, the reasons for undergoing EUS-FNA in such
patients should be added.
3. When mural nodules, thick septa, thickened walls, or masses were present, did
you perform additional FNA/B of these lesions?
4. In Table 1, the size of the mural nodule/mass should be described.
5. Did you perform contrast-enhanced EUS?
6. In the Supplementary Table, formal pathology according to WHO
classification should be given.
MINOR POINTS
1. Page 8, line 177. 'WFs' should be spelled out as 'worrisome features.'
