Clinical appraisal and data extraction were conducted independently by 2 reviewers. A meta-analysis was performed using a random effects model.RESULTS： Outcomes of 1611 procedures from 4 randomized controlled trials and 12 retrospective studies were analyzed. Compared to CODG, LADG was a longer procedure （weighted mean difference [WMD] 54.3; 95% confidence interval [CI] 38.8 to 69.8; P 〈 0.001）, but was associated with a lower associated morbidity （odds ratio [OR] 0.54; 95% CI 0.37 to 0.77; P 〈 0.001）; this was most significant for postoperative ileus （OR 0.27; 95% CI 0.09 to 0.84; P = 0.02）. There was no significant difference between the two groups in anastomotic, pulmonary, and wound complications and mortality. Duration from surgery to first passage of flatus was faster （WMD -0.68; 95% CI -0.85 to -0.50; P 〈 0.001） and the frequency of additional analgesic requirement （WMD -1.36; 95% CI -2.44 to -0.28; P = 0.01）, and duration of hospital stay （WMD -5.51; 95% CI -7.61 to -3,42; P 〈 0,001） were significantly lower after LADG, However, a significantly higher number of lymph nodes were dissected by CODG （WMD -4.35; 95% CI -5.73 to -2.98; P 〈 0.001）. CONCLUSION： LADG for early gastric cancer is associated with a lower morbidity, less pain, faster bowel function recovery, and shorter hospital stay.展开更多
