Reviewer’s report
Title: 
Outcomes and survival of infants with congenital duodenal obstruction
following Kimura procedure with post-anastomosis jejunostomy feeding tube
Version:

Reviewer's report:
The authors analized in this retrospective study the benefit of a post-anastomosis
jejunostomy feeding tube (JFT) after Kimura procedure due to congenital
duodenal obstruction. They found beneficial effects with JFT compared to no
tube. Enteral feeding and full oral feeding was significantly earlier. Time of
parenteral nutrition was shorter with JFT.
Comments:
The Introduction is rather short and could be extended in explaining the problem
in more depth.
The two groups are rather heterogenous. Was the analysis performed in
correcting for confounders?
I was wondering how many surgeons operated on these children. Was one
surgeon performing all the JFT operations? This might be an additional
confounder.
