AIM: To elucidate the current status of laparoscopy-assisted distal gastrectomy (LADG) with regard to its short-term outcomes by comparing it with conventional open distal gastrectomy (CODG). METHODS: Original articles published from January 1991 to August 2006 were searched in the MEDLINE, EMBASE, and Cochrane Controlled Trials Register. 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.
