Safety and Short-term Efficacy of Laparoscopic Assisted Distal Gastrectomy versus Open Distal Gastrectomy in D2 Radical Surgeries for Locally Advanced Distal Gastric Cancer:A Meta-analysis / 中国医科大学学报

ABSTRACT

Objective To conduct a Meta?analysis to compare the safety and short?term efficacy of laparoscopic assisted distal gastrectomy (LADG)and open distal gastrectomy(ODG)in D2 radical surgeries for locally advanced distal gastric cancer. Methods The literatures from Janurary,1990 to August,2014 on the evaluation of safety and short?term efficacy of LADG versus ODG in D2 radical surgeries for locally advanced distal gastric cancer were collected. The quality of the enrolled articles was evaluated and the software Revman 5.2 was adopted to analyze the cura?tive effect. Results Totally 25 articles met the inclusion criteria,including 5 044 patients with treatment of D2 radical surgeries for locally advanced distal gastric cancer. There was no significant difference in the cleaning number of lymph nodes between LADG and ODG in patients undergoing D2 radical surgeries for locally advanced distal gastric cancer. The operation time was longer for LADG than ODG,but the postoperative evaluation in?dexes such as the intraoperative blood loss and the short?term efficacy of LADG were superior to ODG. Conclusion In the treatment of locally ad?vanced distal gastric cancer,there were differences in the safety and short?term efficacy between LADG and ODG,and surgeons should give concern to these differences in clinical practice to select appropriate surgical approaches. Further research is still needed to explore the long?term efficacy.
