title: Laparoscopic Colectomy Versus Open Colectomy for Treatment of Transverse Colon Cancer: A Systematic Review and Meta-Analysis.
abstract: BACKGROUND
  The surgical management of transverse colon cancer (TCC) is still not standardized. The aim of this meta-analysis was to evaluate the effect of laparoscopic colectomy (LC) for treatment of TCC in terms of short-term and long-term outcomes compared with open colectomy.
  
  
  METHODS
  A systematic literature search with no limits was performed in PubMed and Embase. The last search was performed on September 15, 2016. The short-term outcomes included intraoperative outcomes, postoperative outcomes, and oncological surgical quality. The long-term outcomes included overall survival (OS) and disease-free survival (DFS).
  
  
  RESULTS
  Thirteen articles and one conference abstract published between 2010 and 2016 with a total of 1728 patients were enrolled in this meta-analysis. LC was associated with significant less estimated blood loss, fewer total postoperative complications, and shorter time to first flatus, time to liquid diet, length of hospital stay, and length of postoperative hospital stay. However, longer operative time was needed in LC. There was no statistically significant difference between the groups concerning the intraoperative complications, mortality, ileus, anastomotic leakage, bleeding, wound infection, abdominal infection, lymph nodes harvested, proximal resection margin, distal resection margin, OS, or DFS.
  
  
  CONCLUSIONS
  Our meta-analysis suggests that LC is a safe and feasible technique for TCC associated with less estimated blood loss, fewer total postoperative complications, quicker recovery of intestinal function, shorter length of hospital stay, and equivalent long-term outcomes. Furthermore, a large-scaled, prospective randomized controlled study is warranted to verify those results.
