Purpose: This meta-analysis was carried out to evaluate whether Robotic-assisted gastrectomy (RAG) could be safer and more effective than conventional laparoscopically assisted gastrectomy (LAG) for gastric cancer.
Methods: We searched two operation types (RAG and LAG) in Pubmed, Embase and The Cochrane Library, and manual searches were performed up to April 30th, 2016. Six non-randomized control trials were included. Outcomes evaluated were operation time, number of retrieved LN, blood loss, length of the resection margin, complications, postoperative hospital stay.
Results: 2454 patients in six studies were included (731 patients in RAG group and 1723 patients in LAG group). Operation time was significantly shorter in LAG group (WMD 37.92(95% C .I. 33.25 to 42.60) mins ; p<0.00001). Blood loss volume and postoperative stay were less in RAG group (the former p=0.008; the later p=0.01). The differences of the length of distal resection margin were slight between the two groups (p<0.00001). The number of retrieved lymph nodes, length of the proximal resection margin and postoperative complications were similar in both groups.
Conclusions: We may conclude that RAG is a safe and comfortable treatment for gastric cancer patients instead of LAG. Major research of RAG in the future should focus on evaluating long-term therapeutic effect and reducing cost.
