title: [Antecolic versus retrocolic gastroenteric anastomosis for laparoscopic Roux-en-Y gastric bypass: a prospective randomized control trial].
abstract: OBJECTIVE
  To compare short-term postoperative outcomes between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass(LRYGB).
  
  
  METHODS
  Forty obesity patients were admitted into The First Affiliated Hospital of Jinan University from March 2008 to July 2010. All patients were randomly assigned to undergo antecolic (group A, 20 cases) and retrocolic (group B, 20 cases) gastroenteric anastomosis. Short-term outcomes were compared.
  
  
  RESULTS
  LRYGB procedures were successfully performed in all the 40 patients. There were no significant differences between the two groups in estimated blood loss during surgery, time to flatus passage, time to resumption of oral intake, or length of postoperative hospital stay. The operation time was longer in group B than that in group A [(163.4±28.1) min vs.(131.8±22.7) min, P<0.05]. There were no patients developed internal hernia or anastomotic leakage in either group. Comparison of short-term gastrointestinal symptoms after surgery showed no statistical significance.
  
  
  CONCLUSIONS
  Although retrocolic procedure may be closer to anatomical structure, antecolic and retrocolic anastomosis have comparable short-term outcomes after surgery. Further study is warranted to investigate long-term outcomes.
