Reviewer's report: 
General 
------------------------------------------------------------------------------- 
Major Compulsory Revisions (that the author must respond to before a decision on publication can be reached) 
In the abstract and the discussion the retrospective nature of the study has to be declared. 
The authors have to provide interpretation for the high prevalence of ascites in their non cirrhotic patients 
with portal vein thrombosis and its clinical significance 
------------------------------------------------------------------------------- 
Minor Essential Revisions (such as missing labels on figures, or the wrong use of a term, which the author can be trusted to correct) 
Methodology of thrombophilic screening is not given. Von Willebrand factor is not a thrombophlic risk factor. 
The screening is incomplete (i.e. mutation 20210 of prothrombin has not been investigated). These 
limitations have to appear in the text. 
Check spelling errors in table 1 
In my opinion the section laboratory findings does not add more and should be deleted as well as table III 
Discussion : 
Delete from line 2 to line 9 Delete the sentence on sigmoidoscopic examination 
------------------------------------------------------------------------------- 
Discretionary Revisions (which the author can choose to ignore) 
 Accept after minor essential revisions What next?: 
 An article of limited interest Level of interest: 
 Needs some language corrections before being published Quality of written English: 
 No, the manuscript does not need to be seen by a statistician. Statistical review:
