Abstract:
Objective To systematically evaluate the postoperative pancreatic fistula rate,overall postoperative morbidity rate,overall postoperative mortality rate and length of stay in external stent group versus no stent group for pancreaticcoduodenectomy.Methods The Cochrane Library,PubMed,Embase and CBM data bases were searched to identify randomized controlled trials that compared the effectiveness of external stent versus no stent for pancreaticcoduodenectany.Meta-analysis was performed using the software RevMan 5.2.Results Four trials with 416 patients comparing external stent with no stent were included,the external stent group with 207 patients and the no stent group with 209 patients.The Meta-analysis revealed that,compared the external stent group with the no stent group,the rate of postoperative pancreatic fistula was significantly reduced in the external stent group [RR =0.57,95％ CI(0.41,0.80),P =0.001],especially for the patinets of pancreatic diameter ≤ 3.0 mm[RR =0.55,95 ％ CI(0.37,0.82),P =0.003] and soft pancreatic [RR =0.67,95 ％ CI(0.45,0.99),P =0.040],the overall postoperative morbidity rate of external stent group versus.no stent group was reduced[RR =0.79,95 ％ CI (0.64,0.98),P =0.030],and length of stay was shortened [WMD =-3.98,95％ CI(-6.42,-1.54),P =0.001].There was no difference between the two groups regarding the postoperative pancreatic fistula rate of diameter ＞ 3.0 mm [RR =0.37,95 ％ CI(0.08,1.83),P =0.220],and the overall postoperative mortality rate [RR =0.86,95 ％ CI(0.28,2.65),P =0.800].Conclusions Exental stent significantly reduced the postoperative pancreatic fistula rate and overall postoperative morbidity rate 、shortened the length of stay,and thus it can be identified as a preferable option for Pancreaticcoduodenectomy.
