Comparison of short outcomes between laparoscopic and experienced robotic gastrectomy: A meta-analysis and systematic review

OBJECTIVE: The purpose of this meta-analysis is to compare the short-term outcomes between experienced robotic gastrectomy (RG) and laparoscopic gastrectomy (LG). MATERIALS AND METHODS: We searched the PubMed, Springer Link, Elsevier, and Embase databases for articles published in English before June 2015 using an electronic literature search and including cross-referenced articles. Three studies were eligible for the meta-analysis. The outcomes evaluated were operation time, estimated blood loss, harvested lymph nodes, complication, and postoperative hospital stay. RESULTS: Of a total of 562 patients, 165 underwent RG and 397 underwent LG. Operation time was significantly longer in the RG group [weighted mean difference (WMD): 21.49, 95% confidence interval (CI): 12.48-30.50, P < 0.00001). Estimated blood loss, harvested lymph nodes, complication, and postoperative hospital stay were similar between the two groups. CONCLUSION: Experienced RG has similar short-term outcomes to LG that is performed by sophisticated laparoscopic surgeons, except for operation time.
