Pancreatogastrostomy vs pancreatojejunostomy after pancreaticoduodenectomy: An updated meta-analysis of RCTs and our experience.

Abstract

BACKGROUNDPancreatoduodenectomy (PD) is one of the most important operations in hepatobiliary and pancreatic surgery.AIMTo evaluate the advantages and disadvantages of pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG).METHODSThis meta-analysis was performed using Review Manager 5.3. All clinical randomized controlled trials, in which patients underwent PD with pancreatico-digestive tract reconstruction via PJ or PG, were included.RESULTSThe search of PubMed, Wanfang Data, EMBASE, and the Cochrane Library provided 125 citations. After further analysis, 11 trials were included from nine counties. In all, 909 patients underwent PG and 856 underwent PJ. Meta-analysis showed that pancreatic fistula (PF) was a significantly lower morbidity in the PG group than in the PJ group (odds ratio [OR] = 0.67, 95% confidence interval [CI]: 0.53-0.86, P = 0.002); however, grades B and C PF was not significantly different between the two groups (OR = 0.61, 95%CI: 0.34-1.09, P = 0.09). Postoperative hemorrhage showed a significantly lower morbidity in the PJ group than in the PG group (OR = 1.47, 95%CI: 1.05-2.06, P = 0.03). Delayed gastric emptying was not significantly different between the two groups (OR = 1.09, 95%CI: 0.83-1.41, P = 0.54).CONCLUSIONThere is no difference in the incidence of grades B and C PF between the two groups. However, postoperative bleeding is significantly higher in PG than in PJ. Binding PJ or binding PG is a safe and secure technique according to our decades of experience.
