Abstract

Introduction

Despite the theoretical advantages of Robotic gastrectomy (RG) over laparoscopic gastrectomy (LG), the benefit of RG compared to LG remains controversial. To address this controversy, we evaluated the outcomes of RG compared to LG in the high-volume gastric cancer center.

Materials and methods

This single-center retrospective cohort study enrolled patients of RG and LG from January 2013 to December 2017 using propensity score matching. Results of operation, and overall survival were analyzed.

Results

For RG, 268 patients were enrolled, and 733 patients with LG were matched. The four gastric methods were matched at the following ratios; Distal gastrectomy (RG: 35.8 % vs LG: 38.7 %), Total gastrectomy (RG: 16.0 % vs LG: 13.9 %), Pylorus-preserving gastrectomy (RG: 46.3 % vs LG: 44.7 %), Proximal gastrectomy (RG: 1.9 % vs LG: 2.6 %) The median number of retrieved lymph nodes (RG: 36.0 vs LG: 37.0, p = 0.247) and supra-pancreatic lymph nodes (RG: 8.0 vs LG: 7.0, p = 0.647), showed no difference. No difference was observed in complications (RG: 21.3 % vs LG: 21.4 %, p = 1.000), and severe complications (RG: 13.1 % vs LG: 12.7 %, p = 0.961) The 5-year overall survival was not significantly different (RG: 94.8 % vs LG: 93.1 %, hazard ratio: 0.76, 95 % confidence interval: 0.41–1.40, p = 0.379).

Conclusion

Our study observed no advantage in RG compared to LG regarding short-term and oncologic outcomes. To take advantage of RG, developing new articulating efficient devices would be necessary.

倾向评分匹配方法下机器人和腹腔镜胃切除术的临床效果：韩国某大容量胃癌中心5年数据

尽管机器人胃切除术（RG）在理论上优于腹腔镜胃切除术（LG），但与腹腔镜胃切除术相比，机器人胃切除术的益处仍然存在争议。为了解决这一争议，我们在大容量胃癌中心评估了RG与LG的结果。材料与方法本研究采用倾向评分匹配方法，于2013年1月至2017年12月对RG和LG患者进行单中心回顾性队列研究。分析手术结果及总生存率。结果RG组入组268例，LG组匹配733例。四种胃法按以下比例配对；远端胃切除术（RG: 35.8% vs LG: 38.7%）、全胃切除术（RG: 16.0% vs LG: 13.9%）、保幽门胃切除术（RG: 46.3% vs LG: 44.7%）、近端胃切除术（RG: 1.9% vs LG: 2.6%）淋巴结清扫中位数（RG: 36.0 vs LG: 37.0, p = 0.247）和胰上淋巴结清扫中位数（RG: 8.0 vs LG: 7.0, p = 0.647）差异无统计学意义。并发症（RG: 21.3% vs LG: 21.4%, p = 1.000）和严重并发症（RG: 13.1% vs LG: 12.7%, p = 0.961） 5年总生存率无显著差异（RG: 94.8% vs LG: 93.1%，风险比：0.76,95%可信区间：0.41-1.40,p = 0.379）。结论：本研究未观察到RG与LG在短期和肿瘤预后方面的优势。为了充分利用RG，有必要开发新的高效关节装置。
