Early complications of pancreaticojejunostomy or pancreaticogastrostomy after pylorus preserving pancreaticoduodenectomy

Abstract

Objective To evaluate the early postoperative complications of pancreaticojejunostomy (PJ) or pancreaticogastrostomy (PG) following pylorus preserving pancreaticoduodenectomy (PPPD).Methods Clinical data of 97 patients undergoing PPPD,in Zhongshan Hospital,Fudan University from June 2011 to October 2012,were retrospectively analyed.Digestive tract continuity was established respectively by PG(n-45) or PJ(n =52) after PPPD.Results The demographic characteristics of both group were not significantly different.In the two groups,there were not statistically significant difference in those postoperative complications such as biliary fistula,introabdominal infection,bleeding,and the rc-admission rate.The rate of pancreatic fistula in PJ group was significantly higher than that in the PG group (28.85％ vs.6.67％,P =0.033).However,in PG group the incidence of delayed gastric emptying was significantly higher than that in the PJ group (22.22％ vs.5.77％,P =0.018),and the average length of stay was significantly longer than that in PJ group (19.28 ± 11.04 vs.15.09 ± 6.21 ; P =0.034).In PJ group,one patient died of pancreatic fistula and ensuing surgical site infection and intra-abdominal hemorrhage,there was no mortality in PG group.Conclusions After PPPD,PG and PJ are both safe ways of digestive tract reconstruction.But compared to PJ,PG can decreas the rate of pancreatic fistula but may increase the risk of postoperative delayed gastric emptying,and prolong postoperative hospital stay.
