Retrospective Analysis Of Robotic-assisted Versus Laparoscopic Anterior Resection For Rectal Cancer

Objectives:1、To compare the short-term results between robotic-assisted anterior resection(R-AR),and laparoscopic anterior resection(L-AR)in rectal cancer patients.2、Assess the safety and feasibility of Da Vinci robotic-assisted radical resection for rectal cancer Methods:The clinicopathological data of 250 patients with rectal cancer undergoing R-AR or L-AR in the first affiliated hospital of nanchang university from January 2016 to December 2017 were retrospectively analyzed.According to gender,age,ASA score,pathological T stage,pathological N stage and tumor differentiation degree,Finally,85 cases treated by R-AR group and 85 cases by L-AR group were enrolled.The short-term efficacy of the two groups was compared.Patient characteristics were not significantly different between the groups.Results:All patients successfully completed the surgery,no transfer to open surgery patients.Compared with L-AR,R-AR had similar soft diet(4.9±1.1days VS.4.8±1.2days,P=0.893)and length of stay(9.2±2.8 days VS.8.6±2.4 days,P=0.098),less blood loss(167±155ml VS.105±73 ml,P=0.004).Mean number of harvested lymph nodes was 13±5 in the R-LAR group and 14±5.0 in the L-LAR(P=0.386).There were also similar complication And severity of complication(P=0.398),the difference was not statistically significant.The postoperative pathological specimens in the robotic group were all intact,and 2 cases in the laparoscopic group were damaged.Conclusion:Compared with laparoscopic anterior,robotic anterior in rectal cancer could achieve similar short-term outcomes.Robotic surgery is safe and feasible in the treatment of rectal cancer patients.The short-term outcomes of the robotic proctectomy are better than those of the laparoscopic proctectomy in terms of trauma,bleeding and recovery of intestinal function,so it has a broad application prospect.
