Reviewer's report:
PEER REVIEWER ASSESSMENTS:
OBJECTIVE - Full research articles: is there a clear objective that addresses a testable research
question(s) (brief or other article types: is there a clear objective)?Yes - there is a clear objective
DESIGN - Is the current approach (including controls and analysis protocols) appropriate for the
objective?Yes - the approach is appropriate

PEER REVIEWER COMMENTS:GENERAL COMMENTS:
-This is an interesting paper about a rare condition which too often is diagnosed late. Even ifnumbers are small and it is a retrospective series, the authors highlighted the points of interest thatcan be used in clinical practice:- They tried to identify factors responsible for delayed diagnosis and findings which may indicatethe possible diagnosis at earlier stage- They could explain better why children did not undergo MRI/MRCP instead of a CT scan,considering that doesn't give radiation and it has a higher sensitivity.
REQUESTED REVISIONS:
- They could explain better why patients undergo this sequence of imaging modalities, also after
referral to tertiary center.- Underline the best way in the clinical practice when there is a suspicion of CS.- Improve language.
