Reviewer’s report
Title: 
Recurrent umbilical varix rupture with hemoperitoneum: a case report and
review of literature
Version: 
1 
Date: 
14 Nov 2021
Reviewer's report:
The authors presented a rare case of non-traumatic hemoperitoneum due to
intraabdominal varices rather than HCC rupture. This 
is an interesting case.
However, several points should be clarified:
1. Introduction: Varices is a complication of liver cirrhosis. Please cite some
article after "spontaneous varix rupture is a lethal complication of liver cirrhosis
patients, who had portal hypertension".
2. Case presentation: Can the author show the images of first time CT with "
atypical hepatic lesion at S4"
3. Can the author give the subtitle in the video? Because the non-Chinese
country may not understand the video.
