Title: The Application of magnetic anchoring traction device in assisting donor liver bench
surgery in classic orthotopic liver transplantation
Version: 2 Date: 09 May 2022
Reviewer:  Francesca Marcon
Reviewer's report:
I read with great interest this paper on the use of MAT devices to help in liver back table
preparation for implantation. Although I understand the enthusiasm generated by 30 minutes
saved in preparing the liver, I do not see any true advantage in using this type of device: the
rate of injuries is almost the same, and particularly no injuries were reported during the arterial
preparation, which is the most delicate part of the back bech and could jeopardise the entire liver
transplant procedure and thus patient's safety.
I also have to question about the methodology. The grafts were assigned to the two groups
according Authors' preferences and without a randomization, which could have led to biases.
Also, is there any particular reason why you used only DCD and not DBD too? You did not
specified if these grafts were eventually refused for transplantation because of ?cirrhosis ?others,
and went for research only?
And finally, if we agree that this device could partially overcome staff shortage, we must always
bear in mind that this can never replace a good mentoring from an experienced surgeon to a
more junior one. And if this last is not able to properly expose the vessels or the tissue, probably
s/he should be taught better instead of being replaced by a magnetic device.
