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.
