da Vinci robotic system versus laparoscopic surgery for colorectal cancer / 中华普通外科杂志

ABSTRACT

Objective To compare the surgical outcomes of RAC versus LAC for the surgery of sigmoid-rectal cancer.Methods In this study,19 patients received robotic assisted colectomy (RAC)and 37 patients received laparoscopic assisted colectomy (LAC).Results The duration of surgery was longer in the RAC group (240 ± 76) min vs.(177 ± 74) min,t =3.006,P =0.004.The blood loss was less in the RAC group (67 ±40) vs.(153 ±151) ml,t =-2.422,P=0.019.The time to tolerate solid food was shorter in the RAC group (6.1 ±2.2)d vs.(7.4 ±4.4)d,t =-1.329,P =0.189 and the postoperative hospital stay was shorter in the RAC group (8.5 ± 2.6) d vs.(10.0 ± 3.6) d,t =-1.577,P =0.121.Mobidity and number of lymph nodes harvested were similar in both groups.7 cases were converted to open surgery in LAC group but none in RAC group.Conclusion Compared to laparoscopic surgery,Robotic-assisted colorectomy was safe and associated with less blood losses,lower conversion rate to open surgery and faster recovery of bowel function.
