!!!NEW!!! CLINICAL FORUM !!!NEW!!!
to make the quarterly livelier and more beneficial for doctors and scientists !!!

On June the 1st, 2021 VSJ launches a new discussion platform in the journal.

We invite all MIS surgeons to rapidly submit for publication:
- small forms describing unusual clinical situations related to their practice,
- short clinical comments relating to any publications in VSJ, including the clinical situations described above
- brief communications of original studies deserving fast publication
- your personal opinions as part of a larger discussion on the VSJ publication
- letters concerning the topics described above

Clinical Forum gives you a means of rapid presentation of your findings in the medical databases, scientific citations on the international forum, and also an Impact Factor!

Introduction
To compare the outcomes of robot-assisted (RAGD2) and laparoscopy-assisted gastrectomy with D2 lymphadenectomy (LAGD2) for patients with gastric cancer.

Material and methods
Relevant articles published up to September 2020 were searched. The weighted mean difference (WMD) was used to pool continuous variables, while risk ratio (RR) was calculated for dichotomous outcomes.

Results
RAGD2 required a longer operating time (WMD = 29.78, 95% confidence interval (CI): 15.97–43.59) and had less operative blood loss (WMD = 31.93, 95% CI: 44.03 to 19.83), shorter time to first flatus (WMD = 0.13, 95% CI: 0.22 to 0.04), shorter time to liquid diet (WMD = 0.20, 95% CI: 0.28 to 0.12), and fewer severe complications (RR = 0.62, 95% CI: 0.43–0.90) and overall complications (RR = 0.75, 95% CI: 0.62–0.91) than LAGD2.

Conclusions
RAGD2 could be beneficial in reducing operative blood loss and postoperative complications relative to LAGD2.
