Reviewer's report:  
 
The authors report a case of intestinal perforation  in a young patient on PD for  ix years and 
repeated episodes of peritonitis. They hypothetize that the cause of perforation are the num ber of  
that weren´t adequately treated peritonitis . The authors must improve the text and the 
conclusion, which in my opinion is inconsistent.  
 
I think they must answer the following questions:  
 
Line  29    . It's important to know the origin of ESRD beca use patients with amyloidosis and 
ADPKD for example have a higher incidence of intestinal perforation .  
 
Line 30 "A peritoneal dialysis catheter was placed in August 2012"  
 
Since peritoneal catheter can be a cause of intestinal perforation the side  at the catheter inserted 
must be mentioned. The Fig 1 doesn´t clarify this point.  
 
Line 32" Repeated episodes of dialysis associated peritonitis had not been regularly treated"  
 
I can´t understand what the authors mean  
 
Lines 62 -63 "Perforation may  also occur in association with chronic peritoneal dialysis, with its 
repeated episodes of peritonitis and friction of catheters, which can damage the intestinal wall. "
