Pancreatic fistulae after a pancreatico-duodenectomy: are pancreatico-gastrostomies safer than pancreatico-jejunostomies? An expertise-based trial and propensity-score adjusted analysis

AbstractBackgroundA pancreatic fistula (PF) is a major contributor to morbidity and mortality after a pancreaticoduodenectomy (PD). There remains debate as to whether re-establishing pancreaticoenteric continuity by a pancreatico-gastrostomy (PG) can decrease the risk of a PF and complications compared with a pancreatico-jejunostomy (PJ). The outcomes of patients undergoing these reconstructions after a PD were compared.MethodPatients undergoing a PD between 1999 and 2011 were selected from a prospective database and having undergone either a PG or PJ reconstruction. A propensity-score adjusted multivariate logistic regression was performed to identify the effect of surgical technique on outcomes of PF, delayed gastric emptying (DGE) and total complications.ResultsTwenty-three out of 103 and 20 out of 103 (P = 0.49) patients had PF and 74 out of 103 and 55 out of 103 patients had all-grades DGE in the PG and PJ groups, respectively (P = 0.02). The groups did not differ with regards to Clavien–Dindo grade of complications (P = 0.29) but did differ with regards to the Comprehensive Complication Index (CCI) (38.4 versus 31.4 for PG versus PG, respectively, P = 0.02.) Propensity-score adjusted multivariate analysis showed no effect of PG on PF (P = 0.89), DGE grades B/C (P = 0.9) or CCI (P = 0.41). There remained an effect on all-grades of DGE (P = 0.012.)DiscussionPatients undergoing PG reconstruction had a similar rate of PF as those undergoing a PJ after a PD
