Abstract

Background: The oncologic validity of laparoscopic-assisted distal gastrectomy (LADG) in the treatment of advanced gastric cancer (AGC) remains controversial. This study is a systematic review and meta-analysis of the available evidence. Materials and Methods: A comprehensive search was performed between 2008 and 2014 to identify comparative studies evaluating morbidity/mortality, oncologic surgery-related outcomes, recurrence and survival rates. Data synthesis and statistical analysis were carried out using RevMan 5.2 software. Results: Eight studies with a total of 1456 patients were included in this analysis. The complication rate was lower in LADG [odds ratio (OR) 0.59; 95% confidence interval (CI) = 0.42-0.83; P <0.002]. The in-hospital mortality rate was comparable (OR 1.22; 95% CI = 0.28-5-29, P = 0.79). There was no significant difference in the number of harvested lymph nodes, resection margins, cancer recurrence rate, cancer-related mortality or overall and disease-free survival (OS and DFS, respectively) rates between the laparoscopic and the open groups (P > 0.05). Conclusion: The current study supports the view that LADG for AGC is a feasible, safe and effective procedure in selected patients. Adequate lymphadenectomy, resection margins, recurrence, cancer-related mortality and long-term outcomes appear equivalent to open distal gastrectomy (ODG).
