COMPLICATION, GASTRIC CANCER
Laparoscopic surgery has become an essential surgical option to treat patients with gastric cancer over the past two decadesRobotic surgery systems have been widely used to overcome the restrictions of laparoscopic surgery technologyThe earlier da Vinci Si and Xi systems (Intuitive Surgical Inc.) also allowed reduced-port surgery using a single-site system. However, less experienced surgeons found the docking to be challenging, which limited the widespread uptake of these systems. Thus, the da Vinci SP system was developed as a single-port-based multichannel cannula that maintains the advantages of conventional robotic surgical systems, such as high-resolution three-dimensional images and wristed anti-tremor action. Therefore, da Vinci SP is a promising system that combines robotic surgery with a reduced-port approach.This prospective study aimed to confirm the applicability of reduced-port distal gastrectomy using the da Vinci SP system in patients with gastric cancer. We used surgical outcomes and early complication rates to assess the safety and feasibility of da Vinci SP robotic distal gastrectomy (SPRDG). Furthermore, we describe our initial experiences and surgical techniques to increase the potential application of the da Vinci SP robotic system.
