Title: 
Retrograde Coiled Spring Jejunal Intussusception in an Infant due to Foley
Catheter Gastrostomy: A Case Report
Version: 
1 
Date: 
13 Feb 2022
Reviewer's report:
The case is interesting, but it cannot be accepted in its current form until the
suggestions listed below have been heeded.
Abstract
- Page 2 Lines 28-29. "Stamm gastrostomy 
with a Foley catheter is a common
feeding tube procedure"
This statement should be clarified. Really, is Stamm gastrostomy commonly
performed with Foley catheters? Perhaps due to lack of avalability of other
feeding tubes due to their higher peice or their small size. In any case, they will
be carried out with Pezzer catheter. 
Foley catheters should only be used temporarily to avoid closure of the
gastrostomy site when the catheter has been accidentally lost and no other device
is available. 
Background
- Page 3
Brackground needs to be revised, in the same sense as the comments already
made in the abstract.
Lines 58-59. "In children, the use of Foley or Pezzer catheters as an open
gastrostomy tube with the Stamm technique is a common procedure [2, 4]". 
Citations 2 and 4 do not support the claim that the use of Foley or Pezzer
cathethers is common in children. In addition, citation 4 is from 1966. No
reference is made to any of the ASPEN enteral nutrition guidelines [1) Bankhead

Lines 60-62. In the complications it should be added that the migration of the
balloon can cause intestinal obstruction.
Lines 65-67. Comment that the way to avoid these complications due to catheter
mobilization is training, even in those that have an external fixation device.
Case presentation
- 
Page 5. Line 125. Please, note the brand and size of the gastrojejunostomy tube
placed in the patient.
Discussion and Conclusions
- 
Page 9. Lines 205-206. Please, add that it is essential that nursing has a training
program for families.
- 
Page 10. Lines 234-235 and 244-245. If there have been multiple consecutive
intussusceptions, it could be argued that if the mother had known the risks of
displacement of the gastrostomy tube, early warning would probably have
reduced the severity of the condition. Please make a comment.
- 
Page 11. Lines 270-271. Justify why a Foley catheter is used when performing
gastrostomy if it is not recommended?
- 
Page 12. 
Lines 277-278. This statement is totally true. Correct comments on lines 254-
256, and lines 270-271 that contradict them.
Lines 280-283. Please improve the conclusion.
