RTG is a safe and feasible surgical procedure for the treatment of GC with acceptable morbidity and mortality. More complications were observed for RTG, indicating that RTG is more invasive than RDG. Age >= 70 years and surgeons' experience <= 25 cases were identified as independent risk factors for overall complication in patients undergoing robotic gastrectomy for gastric cancer.
Background This study was designed to compare the postoperative complications after Robotic total gastrectomy (RTG) and robotic distal gastrectomy (RDG) and to systematically evaluate the safety and feasibility of RTG for the treatment of gastric cancer (GC). Methods Patients with GC who underwent RTG or RDG for curative intent between March 2010 and August 2019 were analyzed. We used propensity score matching (PSM) to reduce selection bias. The morbidity and mortality within 30 days after surgery between the RTG and the RDG groups were compared. Results According to Clavien-Dindo (C-D) classification, the morbidity and mortality of the RTG group were comparable to those of the RDG group. Subgroup analyses showed no significant difference between the RTG and RDG groups in all stratified parameters (all P > .05). Multivariate analysis revealed that age >= 70 years (P = .002) and surgeons' experience <= 25 cases (P = .013) were independent risk factors for overall complication. Surgeons' experience <= 25 cases (P = .010) was identified as an independent risk factor for severe complication. Conclusion RTG is a safe and feasible surgical procedure for the treatment of GC with acceptable morbidity and mortality. More complications were observed for RTG, indicating that RTG is more invasive than RDG.
