The short-term efficacy of 3D versus 2D laparoscopic radical resection for rectal cancer: A meta analysis

Abstract

Objective To systematically review the short-term clinical efficacy of 3D versus 2D laparoscopic radical resection for rectal cancer. Methods Such databases as PubMed, The Cochrane Library, Web of Science, EMbase, CNKI, WanFang and VIP were electronically searched for published articles at home and abroad on the short-term clinical efficacy of 3D versus 2D laparoscopic radical resection for rectal cancer from the database establishment to March 1st, 2019, and collected relevant literature references. Meta-analysis was performed using RevMan 5.2 software. Results A total of 1 169 patients were included in 11 studies (2 randomized controlled trials, RCTs, 9 nRCTs), including 601 patients in the 3D laparoscopic group and 568 patients in the 2D laparoscopic group. Blood loss (P 0.05). There was no evidence of publication bias in studies used for operation time (P=0.693). Conclusion Compared with 2D laparoscopic rectal cancer surgery, 3D laparoscopic surgery can also achieve radical resection of rectal cancer, and has the advantages of shorter operation time, less intraoperative blood loss, lower postoperative complications, shorter hospital stay, and more harvested lymph node.
