Objective:The study compared laparoscopy-assisted gastrectomy(LAG) with open gastrectomy(OG) in the management of advanced gastric cancer(AGC).Methods:Literature search was performed in the Medline,Embase,and Cochrane Library databases to identify control studies that compared LAG and OG for AGC.A meta-analysis was conducted to examine the surgical safety and oncologic adequacy,using the random-effect model.Results:Seven eligible studies including 815 patients were analyzed.LAG was associated with less blood loss,less use of analgesics,shorter time of flatus and periods of hospital stay,but longer time of operation.The incidence of most complications was similar between the two groups.However,LAG was associated with a lower rate of pulmonary infection(odds ratio(OR) 0.19;95% confidence interval(CI) 0.05 to 0.68;P0.05),overall mortality(OR 0.65;95% CI 0.39 to 1.10;P>0.05),cancer-related mortality(OR 0.64;95% CI 0.32 to 1.25;P>0.05),or recurrence(OR 0.62;95% CI 0.33 to 1.16;P>0.05).Conclusions:LAG could be performed safely for AGC with adequate lymphadenectomy and has several short-term advantages compared with conventional OG.No differences were found in long-term outcomes.However,these results should be validated in large randomized controlled studies(RCTs) with sufficient follow-up.
