In Japan in 2019, more than 2 out of every 3 robot-assisted stomach and gut surgeries used the da Vinci Xi robot — making it the most popular surgical robot for these operations nationwide.

What we've found so far suggests that the da Vinci Xi surgical system was the most commonly used robot for gastrointestinal surgeries in Japan in 2019. Our analysis of the available evidence indicates that more than two out of every three robot-assisted stomach and gut surgeries in Japan during that year used this system [1]. We reviewed one key assertion, which supports the idea that the da Vinci Xi was the leading robotic platform for these procedures nationwide at that time [1]. The evidence we’ve seen does not provide an exact percentage, but it does state that use of the da Vinci Xi exceeded two-thirds of all such surgeries. That means its use was more common than any other robotic system for gastrointestinal operations in Japan in 2019, based on what we’ve found so far. No studies or assertions we analyzed contradicted this finding, and we currently have no data suggesting a different pattern. However, our analysis is limited to the information available, and we cannot confirm finer details like the precise percentage or how usage varied across hospitals or regions. Our current analysis shows a clear pattern of widespread adoption of the da Vinci Xi for robot-assisted gastrointestinal surgeries in Japan during 2019, but we don’t have exact numbers beyond the “more than two-thirds” estimate. As more data becomes available, our understanding may become more detailed. Practical takeaway: If you were having a robot-assisted stomach or gut surgery in Japan in 2019, it was more likely than not that the da Vinci Xi system was used.
