PSEUDOCYSTS. A CASE PR ESENTATION

Reviewer’s report:  
 
General comment  
 
This report documented a case of multiple pancreatic pseudocysts presenting jaundice 
accompanied with Wirsung duct rupture without traumatic history.  
 
The reviewer wondered if the conclusion written in the Abstract can be drawn fro m this case 
presentation.  
 
 
Specific comments  
 
1) P3, L60 -63. The authors described EUS allows a sample of cyst fluid for testing amylase 
and cytology, essential to differentiate inflammatory pseudocysts from cystic neoplasms. 
However, they also stated in th e text that "IPMN could be considered because of the 
location of the mass in pancreas head….. Consequently pseudocyst diagnosis was 
hypothesized." The reviewer also feel the effect of EUS -FNA cyst fluid analysis can only 
"suggest" but not "conclude", as yo u finally concluded by laparotomy, not by EUS -FNA .  
 
2) P5, L85 -89. There are several tumor markers descriptions (CEA, CA19 -9, CA125, CgA, 
NSE). Please, add the normal range.  
 
3) P6, L101 -102. EUS confirmed the multiple pancreatic cystic lesions and fine n eedle 
aspiration ruled out the presence of neoplastic cells (Fig. 3).  
 
Do authors want to say cytology by EUS -FNA? or biopsy? Also, why you can say rule out? How 
accurate are the aspiration cytology or cyst fluid analysis for the diagnosis of pathological 
diagnosis. Authors should quote the literatures describing the sensitivity, specificity, accuracy…. 
of the cytology/fluid analysis of the pancreatic cystic lesions.  
 
4) P6, L105. What was the pathological diagnosis of "A large mass"?  
 
5) P8, L155. Managemen t of PFCs is  ….. to duct disruption. Current case also showed duct 
disruption, a cause of these pseudocysts suggested by authors. What caused the 
disruption?
