Title: Comparison of clinical outcomes of single-incision versus multi-port laparoscopic surgery
for descending colon cancer: a propensity score-matched analysis
Version: 1 Date: 02 Aug 2022
Reviewer:  Yasuhiro Ishiyama
Reviewer's report:
A study on SILS for transverse colon cancer. Short and long-term results are also described and
are considered very useful.
In terms of site of recurrence, SILS had 4 cases of liver metastasis and 2 cases of peritoneal
dissemination. On the other hand, there was no peritoneal dissemination in the MPLS group.
The discussion on this is interesting.
There is no statistically significant difference in N, but N1 (27.3%) and N2 (11.4%) are slightly
higher in the SILS group. It will be interesting to see what happens when classified as N1a,
N1b, and N2aN2b.
The title of the study should suggest a middle or oncological outcome, not just a short one, since
there are 42 months of follow-up.
In the overall cohort, the D3 lymph node dissection rate was significantly larger in the SILS
group before matching (p<0.001), but was not significant after matching (p=0.085)
#we need to consider this: is the surgeon the same for SILS and MPLS?
It would be better to include the Harzard ratio in the long-term results.
Is there a surgeon setting, etc.?
