Abstract

Background: Robot-assisted gastrectomy (RAG) for gastric cancer is still a controversial surgical technique for adequate tumor resection, lymphadenectomy, and postoperative outcome.

Methods: A meta-analysis analyzed updated clinical trials that have compared RAG with laparoscopy-assisted gastrectomy (LAG) to evaluate whether RAG is equivalent to LAG.

Results: Eight studies were included in the analysis, comprising 1,875 patients. RAG was associated with a longer operative time (p < 0.05), lower estimated blood loss (p < 0.05), and a longer distal margin (p < 0.05). RAG can be performed safely with lower estimated blood loss and a longer distal margin than with LAG. Complications, hospital stay, proximal margin, and harvested lymph nodes for RAG and LAG were similar.

Conclusions: RAG is as acceptable as LAG for obtaining safe complications and for performing radical gastrectomy.
