RESUMEN
Objective To evaluate the postoperative complications and safety of pancreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD).Methods Medline,EMBASE,Science Direct,Springer link,CBM,Cnki,Wan fang and VIP database were retrieved by computer search between 1st January 2004 and 31st March 2014 to collect all the RCT articles on pancreaticojejunostomy versus pancreaticogastrostomy after pancreaticoduodenectomy.The quality of the included trials was studied by assessing the inclusive and exclusive criteria (the PRISMA statement) by 2 researchers independently,then the data were extracted and analyzed using the RevMan 5.2.10 software.Results A total of 6 prospective randomized controlled trials which involved 976 patents were included in the study.There were significant differences between PG and PJ in terms of postoperative pancreatic fistula (RR:0.51 ; 95 ％ CI:0.37-0.70 ; P ＜ 0.0001),intra-abdominal fluid collection (RR:0.55 ; 95 ％ CI:0.34-0.89; P =0.01),and postoperative biliary fistula (RR:0.14; 95％ CI:0.03-0.59; P =0.0008).There was no significant difference in postoperative complications,mortality,delayed gastric emptying,postoperative hemorrhage,reoperation and length of hospital stay (P ＞ 0.05).Conclusions Pancreaticogastrostomy after pancreaticoduodenectomy is superior to pancreaticojejunostomy in safety and practicability.However,large,multicenter prospective randomized controlled trials are still needed to confirm the findings of this meta-anlaysis.
