We have read with interest the article published by Hondo N et al.1 At
present, there are several minimally invasive surgical methods for the
treatment of gastric cancer: Endoscopic mucosal resection (EMR) ,
Endoscopic submucosal dissection (ESD), Laparocopy-assisted radial
gastrectomy (LARG), and Robot-assisted radical gastrectomy (RARG). LARG
and RARG can not only be used for early gastric cancer, but also for the
treatment of advanced gastric cancer, and they have the advantage of a
wide range of surgical indications. Laparoscopic surgery also has some
drawbacks, including a two-dimensional surgical field of view and
limited operational freedom. In order to improve the above shortcomings,
the da Vinci robotic surgical system has emerged in response to the
times. The da Vinci surgical robot system is currently the most advanced
high-tech platform for minimally invasive surgery internationally. It
solves the limitations of traditional laparoscopy in terms of field of
view and operational flexibility, and breaks through the bottleneck of
limited development in traditional laparoscopic surgery. Although we
believe it is a very interesting topic, we would like to offer the
following points for your consideration.
