title: Effect of Billroth II or Roux-en-Y Reconstruction for the Gastrojejunostomy After Pancreaticoduodenectomy: Meta-analysis of Randomized Controlled Trials.
abstract: OBJECTIVE
  This study aimed to compare Billroth II with Roux-en-Y reconstruction after pancreaticoduodenectomy (PD).
  
  
  METHODS
  A literature search was carried out to identify all randomized controlled trials (RCTs) comparing postoperative complications of Billroth II versus Roux-en-Y reconstruction following PD published from 1 January 1990 to 31 August 2014. Pooled risk ratios (RRs) with 95 % confidence intervals (CIs) were calculated using fixed effects or random effects models
  
  
  RESULTS
  In total, three RCTs with 470 patients were included. Using International Study Group of Pancreatic Surgery (ISGPS) definitions, incidences of delayed gastric emptying (DGE) [grades B and C (3.9 versus 12.9 %; RR 0.30, 95 % CI 0.11-0.79; P = 0.01), DGE grade C (0.7 versus 9.6 %; RR 0.11, 95 % CI 0.02-0.61; P = 0.01)] were significantly lower in the Billroth II group than in the Roux-en-Y group, as was the length of hospital stay (weighted mean difference -4.72, 95 % CI -8.91, -0.53; P = 0.03).
  
  
  CONCLUSIONS
  Meta-analysis revealed that the incidence of DGE (grades B and C) after PD can be decreased by using Billroth II rather than Roux-en-Y reconstruction.
