Title: 
Subtotal (segment II-VIII) hepatectomy for bilateral diffuse hepatolithiasis
with compensatory caudate lobe hypertrophy: A report of two cases
Version:

Reviewer's report:
The two clinical cases reported by the authors are 
extremely interesting. It is a
benign hepatic disease little known in the western world but problematic in the
eastern world.Only highly specialized centers are able to deal surgically with the
two cases represented and I congratulate the authors.
In this publication, the use of 3D reconstruction to better define the vascular
rapport of the only segment remaining with respect to the rest of the parenchyma
which has become atrophic is of extreme interest.
The only remark I make and on which the authors must respond is the use of the
following statement: "caudate lobe substitution". I have looked for this definition
in the current literature but I have not found a bibbiographical response. The
same authors in the paper refer to this definition without there being a
bibbiographical response. If the definition is the result of the authors' thought, I
think it is not convenient to create a new definition of segment I hypertrophy
without there being an important anatomical basis.
