Abstract

Objective: Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) are the commonly preferred methods of anastomosis after pancreaticoduodenectomy (PD). The ideal choice of anastomosis remains a matter of debate. Data Sources: Articles published until end of March 2006 comparing PJ and PG after PD were searched. Study Selection: Two reviewers independently assessed quality and eligibility of the studies and extracted data for further analysis. Meta-analysis was performed with a random-effects model by using weighted odds ratios. Data Extraction and Synthesis: Sixteen articles were included; meta-analysis of 3 randomized controlled trials (RCT) revealed no significant difference between PJ and PG regarding overall postoperative complications, pancreatic fistula, intra-abdominal fluid collection, or mortality. On the contrary, analysis of 13 nonrandomized observational clinical studies (OCSs) showed significant results in favor of PG for the outcome parameters with a reduction of pancreatic fistula and mortality in favor of PG. Conclusions: All OCSs reported superiority of PG over PJ, most likely influenced by publication bias. In contrast, all RCTs failed to show advantage of a particular technique, suggesting that both PJ and PG provide equally good results. This meta-analysis yet again highlights the singular importance of performing well-designed RCTs and the role of evidence-based medicine in guiding modern surgical practice.
