Title: Colonic Hematoma after Extracorporeal Shock Wave Litho tripsy for Pancreatic Stones: A 
case report  
 
Version: 1 Date: 31 May 2019  
 
Reviewer: Marianna Arvanitakis  
 
Reviewer's report:  
 
Interesting case. Some co mments:  
 
 
1. Page 7, line 5: There are many reports of splenic hematomaor rupture and it should be added 
in the discussion (Splenic rupture following ESWL for a pancreatic duct calculus.  
 
Leifsson BG, Borgström A, Ahlgren G. Dig Surg. 2001;18(3):229 -30) 
 
 
2. It would be interesting to show the CT images where the relationship between the stones and 
the hepatic flexure are shown, to see if the direction of the shock waves passes from the hepatic 
flexure. Moreover, the fluoroscopy image of the ESWL could be inter esting to show 
anteroposterior and oblique settings of the ESWL on the stones.  
 
 
3. Page 6/line 23: Perforation instead of performation   
 
 
4. Page 7, line 14: Change the sentence "This remind us that we should care for every difference 
appeared during the natur al course or the treatment of CP patients. Each symptom and compliant 
should be noticed to examine complication after P -ESWL." to "This observation underlines the 
importance of assessing thoroughly the patient after each ESWL procedure and taking into 
consideration every new symptoms or modification of a pre -existing (such as pain), in order to 
detect eventual ESWL -related complications".  
 
 
5. Page 3/line 7: "After the first P -ESWL session, the patient complained a new type of pain 
different from the previous  pain pattern." Change to "After the first P -ESWL session, the patient 
complained of a new type of pain different from the previous pain pattern".
