Retrospective Analysis

Reviewer's report:  
 
This is a relatively large scaled study in this research field about the enterotomy in children with 
VEOIBD.  
 
 
1. It would be better to describe whether genotypes of 22 patients were pathogenic variants or 
included variants of unknown significance.  
 
2. Please define the medical management in result 1 and table 1; did they mean 'before 
enterotomy' or 'throughout the study period'?  
How many patients experienced enterotomy after HSCT? Did you mean ten patients underwent 
HSCT before enterotomy (result 1 and table 1) and another 7 patients received HSCT after 
enterotomy (from result 5. follow -up)? How many patients among those 7 patients underwent 
repeated HSCT?  
In previous studies, HSCT showed a high cure rate. If 45% of patients underwent enterotomy 
despite HSCT, this result is quite different from other studies. Please discuss about the result.  
I understand that 7 patie nts experienced HSCT despite enterostomy. Please describe the time 
interval between enterotomy and HSCT.  
 
3. You may analyze the outcome by medical management before enterotomy, such as; a group 
with HSCT vs without HSCT; a group with biologics vs without b iologics.  
 
4. You can give more information about the clinical characteristics such as disease behaviors, 
locations, or type. They can be the important risk factors and outcome parameters. You may 
analyze the results according to the disease type, such as p enetrating/fistulous vs inflammatory 
type.  
It would be better to describe the status of mucosal inflammation and/or mucosal healing with 
basal and follow -up endoscopy and/or fecal calprotectin, if possible.  
 
5. In result 3, improvement of growth parameters at two time points might be due to other 
medical managements after enterotomy, such as biologics or HSCT. You should analyze these 
factors including time interval (follow -up periods) and other managements (including medicine -
free period after surgery) to e valuate the effect of enterotomy on growth because biologics and 
HSCT have shown good results in catch -up growth or relatively high remission rate.  
 
6. Can we know the rate of enterostomy closure and average time interval of it? This can be one 
of the outco mes and give additional information about the prognosis.  
 
- at line 6 in page 6; Please insert "median" and "interquartile range (IQR)" in the statement of 
"...12.0 months [5.0, 27.3]".  
 
- Please modify the title of tables so that they contain information i ndependently; for example, 
'Demographic characteristics of children with VEOIBD with IL10R deficiency'
