This study compared the short- and long-term outcomes of robotic total gastrectomy (RTG) and conventional laparoscopic total gastrectomy (LTG) in patients with clinical stage I/IIA gastric cancer. The results showed that RTG reduced the risk of complications compared to LTG, although the operative time was longer. Overall survival was equivalent between the two approaches.
Background The robotic approach is especially promising for challenging surgeries, such as total gastrectomy. However, it remains unclear whether robotic total gastrectomy (RTG) is superior to conventional laparoscopic total gastrectomy (LTG). The present study aimed to clarify the impact of RTG on short- and long-term outcomes for patients with clinical stage I/IIA gastric cancer. Methods This study included 98 patients with clinical stage I/IIA gastric cancer who underwent minimally invasive total gastrectomy from October 2013 to December 2020 at the Shizuoka Cancer Center. The short- and long-term outcomes of RTG were compared with those of LTG. Results This study included 36 RTG and 58 LTG patients. RTG was associated with a significantly longer operative time than LTG (p = 0.023). All complications tended to be lower in the RTG group than in the LTG group (2.8% and 15.5%, respectively; p = 0.083). There were no patients with anastomotic leakage in the RTG group. The multivariate analysis identified LTG as the only independent risk factor for postoperative complications (odds ratio, 6.620; 95% confidence interval, 1.132-126.4; p = 0.034). The survival of the RTG and LTG groups was equivalent. Conclusions RTG reduced the risk of complications compared to LTG. Patients treated using the two approaches showed equivalent survival.
