case report

Reviewer's report:  
 
35-36  "Repeated peritonitis (more than 4 weeks) due to the peritoneal dialysis had not been 
regularly". What are the words in the brackets referred to?. It's still missing pivotal info 
concerning the peritonitis episodes and their characteri zation/management.  
 
36-37 it has not been reported the analysis which were performed on the fluid noted at the exit -
site. Why, for instance , might it be not an exudative drainage? a pure leakage does not involve 
inflammatory features and it shows a very high quantity of glucose according to the instilled 
peritoneal solution.  
 
Fig. 1 (a,b) --&gt; the presence of abdominal radiography is not mentioned.  
 
80-82 "The main methods of catheter insertion are the Moncrief and Popovich technique and the 
peritoneal wall -anchor technique; both techniques have been used in  a low percentage (0.2%) of 
patients".  
 
Nowadays the modalities of PD catheter insertion are n umerous and the choice depends mostly 
on the experience of the specific center (percutaneous, semi -surgical, surgical...).  
 
The Moncrief -Popovich technique (catheter embedding) consists of inserting PD catheter far in 
advance of anticipated need. Instead o f bringing the external limb of the catheter out to the 
surface, it is embedded under the skin in the subcutaneous space. When the patient needs to start 
dialysis, the external limb is brought to the outside through a small incision. This technique can 
be incorporated into any of the insertion approaches. Thus, it is not a specific modality of PD 
catheter placement rather a "special access techniques" and it is not so widely employed. the 
PWAT is an ancillary technique, too. It is performed either by laparo scopy or open surgery in 
order to eliminate the movement of the catheter in the peritoneal cavity. It is widely used in 
Japan, but it is not introduced worldwide.  
 
So, the statement is not appropriate. Furthermore, the sentence seems to be contradictory in 
itself.  
 
80-93 what do the Authors want to point out (that te perforation in this case is due to pd 
discontinuation?) The perforation due to the presence of unused PD catheter is reported very 
rarely. Did the patient interrupt the PD anytime due to the pe ritonitis episodes?  
 
Anyway, the Authors should clarify and state clearly why do they believe that it does exist a 
correlation between the past peritonitis episodes and the perforation? On what basis is the 
assumption suggested?  
 
What is the alleged link ( even indirect) of cause and effect?  
 
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.
