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: 21 Oct 2022
Reviewer's report:
Thank you for giving me the opportunity to review this manuscript
The authors present a study about a very interesting topic and should be commended for their
project.
They aimed to describes The clinical impact of single-incision laparoscopic surgery (SILS) for
descending colon cancer (DCC)  using PSM. These cases highlighted that the SILS appears safe
and feasible and can provide satisfactory oncological outcomes for patients with DCC.
The topic is interesting and suitable for publication in BMC Gastroenterology.
Results
Table 1 and 2 can be inserted in the same table .
For 137 consecutive patients with stage I–III DCC who underwent SILS or MPLS at two
high-volume multidisciplinary tertiary hospitals between April 2008 and December 2018, the
authors should produce 2 tables related to Univariate and multivariate analyses of risk factors
related to recurrence-free survival and overall survival after propensity score matching using
the suitable covariates that can impact the long term outcomes of the patients using the best
pronostic as reference ( Operative findings, Postoperative complications, Pathological features
and oncological outcomes, Demographic characteristics ). Using a Cox proportional hazard
model of multivariate analysis will be useful for the calculation of independent prognostic
factors. Variables with P < 0.05 by univariate analysis should be subjected to multivariate
analyses. Each test should be two tailed.
