PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: I had the pleasure to review the manuscript entitled
""Combined laparoscopic lymphadenectomy of lateral pelvic and inguinal nodal
metastases using indocyanine green fluorescence imaging guidance in low rectal
cancer after preoperative chemoradiotherapy: A case report"". I would like to
invite the authors to revise their manuscript considering the following points:
- There is no background information or description of the problem in the
abstract to support the study rationale. You have only mentioned the study
objectives in your abstract. I would add one or two sentences as the lead of the
abstract to provide an introduction to the main study topic, to highlight the gap in
knowledge and the motivation or rationale for the study for the abstract readers. 
- What is ""left lateral lymph node"". In anatomic stationing of the lymph nodes,
I am not familiar with ""left lateral"" position. Please use anatomic descriptors.
Based on the provided MR images, probably you mean ""left external iliac
lymph node/lymphadenopathy"".
- The conclusion section of your abstract only repeats your study findings with
no definite interpretation. It needs to be revised thoroughly. I suggest providing a
statement that mentions the overarching clinical implications of your findings
and explains why your findings are relevant/important and how they can shape
future research.
- Please provide more sequences of MR images, including fluid sensitive
sequence. Also, please have more radiologic description for the figure legends,
including the name of the sequence presented, the plane, whether they are post-
contrast or non-contrast, etc.
- More details of the technologic aspects of imaging, including the Tesla strength
of the MR machine, the vendor, contrast used, etc is appreciated. 
- Please provide the size of the lymphadenopathy before and after
chemoradiation.
- What was the SUV max of the lesion and lymphadenothy in PET/CT? You
may use term of ""hypermetabolism"" instead of FDG accumulation.
- Reference # 9 and 18 do not have page numbers.
REQUESTED REVISIONS: 
As above"
