Pancreaticogastrostomy is superior to pancreaticojejunostomy for prevention of pancreatic fistula after pancreaticoduodenectomy: an updated meta-analysis of randomized controlled trials.

OBJECTIVE To review prospective randomized controlled trials to determine whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is associated with lower risks of mortality and pancreatic fistula after pancreaticoduodenectomy (PD). BACKGROUND Previous studies comparing reconstruction by PG and PJ reported conflicting results regarding the relative risks of mortality and pancreatic fistula after these procedures. METHODS MEDLINE, the Cochrane Trials Register, and EMBASE were searched for prospective randomized controlled trials comparing PG and PJ after PD, published up to November 2013. Meta-analysis was performed using Review Manager 5.0. RESULTS Seven trials were selected, including 562 patients who underwent PG and 559 who underwent PJ. The pancreatic fistula rate was significantly lower in the PG group than in the PJ group (63/562, 11.2% vs 84/559, 18.7%; odds ratio = 0.53; 95% confidence interval, 0.38-0.75; P = 0.0003). The overall mortality rate was 3.7% (18/489) in the PG group and 3.9% (19/487) in the PJ group (P = 0.68). The biliary fistula rate was significantly lower in the PG group than in the PJ group (8/400, 2.0% vs 19/392, 4.8%; odds ratio = 0.42; 95% confidence interval, 0.18-0.93; P = 0.03). CONCLUSIONS In PD, reconstruction by PG is associated with lower postoperative pancreatic and biliary fistula rates.
