Abstract:
Objective:To compare the short-term and long-term outcome between robotic gastrectomy and laparoscopic gastrectomy.
Methods:The clinical data of 517 patients who had received robotic gastectomy and laparoscopic gastrectomy between December 2011 and December 2013 at Department of General Surgery, Chinese People′s Liberation Army General Hospital was collected. After propensity score matching, 70 patients in robotic gastectomy and 70 patients in laparoscopic gastectomy were identified. Perioperative outcome and overall survival were compared between the two groups using t test, χ2 test, Kaplan-Meier curve and Log-rank test, respectively. Prognosis factors were analyzed by Cox′s proportional hazards regression.
Results:There were comparable baseline characteristics between patients in robotic group (RG) and those in laparoscopic group (LG). The conversion rate for RG and LG were 5.7% and 4.3% respectively (P=1.000). Compared with LG, RG had similar lymph node retrieval (25.5±7.2 vs. 24.5±8.3, t=0.770, P=0.443) and less blood loss ((147.0±96.8) ml vs. (188.0±111.2) ml, t=-2.326, P=0.021). There were also similar complications (χ2=0.233, P=0.629) and severity of complications (W=70.500, P=0.053). Although there tended to be early mobility, early flatus and less hospital stay for patients in RG group, the difference between RG and LG was not statistically significant. The 3-year survival rate was 72.9% and 60.0% for patients in RG and patients in LG (P=0.578). Multivariable analysis revealed gender (HR=2.529, 95% CI: 1.042 to 6.140, P=0.040), neoadjuvant chemotherapy (HR=0.272, 95% CI: 0.104 to 0.710, P=0.008) and vascular invasion (HR=2.135, 95% CI: 1.027 to 4.438, P=0.042) were independent prognostic factors.
Conclusion:Compared with laparoscopic gastrectomy, robotic gastectomy could achieve similar short-term and long-term outcomes.
