Continuous suture of the pancreatic stump and Braun enteroenterostomy in pancreaticoduodenectomy

AIM:To investigate a new modification of pancreaticoduodenectomy(PD)-a mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy.METHODS:Two hundred and three patients underwent PD from 2009 to 2014 and were classified into two groups:Group A(98 patients),who received PD with a mesh-like running suturing for the pancreatic remnant,and Braun's enteroenterostomy; and Group B(105 patients),who received standard PD.Demographic data,intraoperative findings,postoperative morbidity and perioperative mortality between the two groups were compared by univariate and multivariate analysis.RESULTS:Demographic characteristics between Group A and Group B were comparable.There were no significant differences between the two groups concerning perioperative mortality,and operative blood loss,as well as the incidence of the postoperative morbidity,including reoperation,bile leakage,intraabdominal fluid collection or infection,and postoperative bleeding.Clinically relevant postoperative pancreatic fistula(POPF) and delayed gastric emptying(DGE) were identified more frequently in Group B than in Group A.Technique A(PD with a mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy) was independently associated with decreased clinicallyrelevant POPF and DGE,with an odds ratio of 0.266(95%CI:0.109-0.654,P =0.004) for clinically relevant POPF and 0.073(95%CI:0.010-0.578,P =0.013) for clinically relevant DGE.CONCLUSION:An additional mesh-like running suturing of the pancreatic remnant and Braun's enteroenterostomy during PD decreases the incidence of postoperative complications and is beneficial for patients.
