Robotic-assisted versus conventional laparoscopic-assisted total gastrectomy with D2 lymphadenectomy for advanced gastric cancer: short-term outcomes at a mono-institution
Abstract
Abstract Background Robotic-assisted surgery, a developed technology, is becoming more and more accepted by surgeons. However, the comparison between robotic-assisted total gastrectomy (RATG) and conventional laparoscopy-assisted total gastrectomy (LATG) for advanced gastric cancer (AGC) is seldom reported, or usually the sample sizes reported are small. The current research was designed to compare the short-term outcomes of RATG and LATG with D2 lymphadenectomy for AGC in a mono-institution from China. Methods A total of 205 patients from June 2015 to October 2018 were included in this study. Among them, 106 patients underwent LATG, and 99 patients underwent RATG. The patients’ clinicopathological characteristics, surgical performance and short-term outcomes were retrospectively analyzed. Results The clinicopathological characteristics showed no difference between the LATG group and the RATG group. However, compared with the LATG group, the operation time was longer (P = 0.000), and the operative blood loss (P = 0.000) and the volume of abdominal drainage was less (P = 0.000) in the RATG group. Moreover, the RATG took less time to remove abdominal drainage tube than LATG (P = 0.000). The plasma levels of CRP at 72 h post-operation was lower (P = 0.000), and the number of retrieved lymph nodes was more (P = 0.000) in the RATG group. Nevertheless, the postoperative length of stay (P = 0.890), the time to first flatus (P = 0.448), the postoperative complication (P = 0.915) and the visual analogue pain score at 24 h post-operation (P = 0.457) were comparable between the two groups. Conclusions RATG with D2 lymphadenectomy shows safety and feasibility for AGC and could be served as an alternative treatment for AGC in the future.
