Abstract
BackgroundRobotic-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.MethodsA 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.ResultsThe 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.ConclusionsRATG with D2 lymphadenectomy shows safety and feasibility for AGC and could be served as an alternative treatment for AGC in the future.
Highlights
Robotic-assisted surgery, a developed technology, is becoming more and more accepted by surgeons
The robotic-assisted total gastrectomy (RATG) group was related with less operation blood loss (134.5 ± 12.9 vs. 152.8 ± 12.0 mL, P = 0.000) and longer operation time (203.9 ± 13.6 vs. 183.6 ± 12.1 min, P = 0.000) as compared with the laparoscopy-assisted total gastrectomy (LATG) group
The time to remove abdominal drainage tube was shorter in the RATG group than in the LATG group (6.0 (5.0–27.0) vs. 7.0 (4.0–28.0) days, P = 0.000)
Summary
Robotic-assisted surgery, a developed technology, is becoming more and more accepted by surgeons. 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. It is generally known that the most effective therapeutics for the patients with AGC is partial or total gastrectomy with D2 lymphadenectomy. The appliance of laparoscopy-assisted gastrectomy (LAG) in gastric cancer was initially reported by Kitano et al in 1994 [3]. Several researches have reported that LAG shows better shortterm outcomes and equivalent long-term oncological outcomes for AGC when compared to the open gastrectomy [8,9,10]. LAG has several demerits, including the lack of spatial stereoscopic visualization, straight rigid instruments, amplified hand trembling, long learning curve and high demand for assistants and camera holder [11]
