Abstract：
BACKGROUND: Comparative data on D2-robotic gastrectomy (RG) vs D2-open gastrectomy (OG) are lacking in the Literature. Aim of this paper is to compare RG to OG with a focus on D2-lymphadenectomy.
METHODS: Data of patients undergoing D2-OG or RG for gastric cancer were retrieved from the international IMIGASTRIC prospective database and compared.
RESULTS: A total of 1469 patients were selected for inclusion in the study. After 1:1 propensity score matching, a total of 580 patients were matched and included in the final analysis, 290 in each group, RG vs OG. RG had longer operation time (210 vs 330 min, p < 0.0001), reduced intraoperative blood loss (155 vs 119.7 ml, p < 0.0001), time to liquid diet (4.4 vs 3 days, p < 0.0001) and to peristalsis (2.4 vs 2 days, p < 0.0001), and length of postoperative stay (11 vs 8 days, p < 0.0001). Morbidity rate was higher in OG (24.1% vs 16.2%, p = 0.017).
CONCLUSIONS: RG significantly expedites recovery and reduces the risk of complications compared to OG. However, long-term survival is similar.

摘要：
背景：文献中缺乏D2机器人胃切除术（RG）与D2开腹胃切除术（OG）的比较数据。本文的目的是比较RG与OG，重点是D2淋巴结清扫术。
方法：从国际IMIGASTRIC前瞻性数据库中检索并比较接受D2-OG或RG胃癌患者的数据。
结果：共选择1469例患者纳入研究。1:1倾向评分匹配后，共580例患者进行匹配，并纳入最终分析，每组290人，RGvsOG。RG的手术时间更长（210对330分钟，p<0.0001),术中失血减少（155vs119.7ml，p<0.0001),流质饮食时间（4.4vs3天，p<0.0001)和蠕动(2.4vs2天，p<0.0001),和术后住院时间（11vs8天，p<0.0001)。OG发病率较高(24.1%vs16.2%,p=0.017)。
结论：与OG相比，RG可显著加速康复并降低并发症的风险。然而,长期生存是相似的。
