Meta-analysis of pancreaticogastrostomy versus pancreaticojejunostomy on occurrences of postoperative pancreatic fistula after pancreaticoduodenectomy

Background/Objective: Pancreatic fistula (PF) is the most common and challenging complication after pancreaticoduodenectomy (PD). This meta-analysis aimed to evaluate the impact of pancreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) on occurrences of postoperative PF. Methods: A systematic literature search in the Medline, EMBASE, OVID, and Cochrane databases was performed to identify all eligible randomized controlled trials (RCTs). Pooled estimates were presented with 95% confidence intervals (CI). Results: Six RCTs involving 1005 patients met the inclusion criteria. The incidence of PF [odds ratio (OR) 0.58, 95% CI, 0.42-0.81; p = 0.001], intra-abdominal abscess or collections (OR 0.43, 95% CI, 0.28-0.65; p < 0.001), and biliary fistula (OR 0.28, 95% CI, 0.11-0.74; p = 0.01) were found to be significantly lower in the PG group than in the PJ group. There was no significant difference in overall morbidity, other complications, hospital mortality, or length of hospital stay between the two groups. Conclusion: The meta-analysis showed that PG following PD represents a safe procedure associated with fewer PFs compared with PJ. Copyright (C) 2015, Asian Surgical Association.
