Background: Grade B postoperative pancreatic fistula represents the largest fraction of postoperative pancreatic fistula. A subclassification of grade B postoperative pancreatic fistula has been recently proposed and seems to better stratify postoperative pancreatic fistula clinical and economic burden. Aim of this study was to validate, from a clinical and economic standpoint, grade B postoperative pancreatic fistula subclassification in patients submitted to pancreaticoduodenectomy.Methods: All consecutive patients who underwent pancreaticoduodenectomy and developed biochemical leak or postoperative pancreatic fistula were included. Grade B postoperative pancreatic fistula was subclassified into 3 categories (B1: persistent drainage >21 days, B2: pharmacological treatments; B3: interventional procedures). Postoperative pancreatic fistula clinical and economic burden was assessed by evaluating postoperative complications, length of hospital stay, and overall hospital costs.Results: Overall, 289 patients developed biochemical leak or postoperative pancreatic fistula. Of these, 34 had biochemical leak (12%), 25 had grade B1 postoperative pancreatic fistula (9%), 91 had grade B2 postoperative pancreatic fistula (31%), 94 had grade B3 postoperative pancreatic fistula (32%), and 45 experienced grade C postoperative pancreatic fistula (16%). The severity of postoperative complications significantly increased across biochemical leak and postoperative pancreatic fistula categories (P <.001), but it was comparable between biochemical leak and grade B1 postoperative pancreatic fistula. There was no significant difference in terms of length of hospital stay between patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000). Overall hospital costs were similar for patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000), whereas they significantly increased across all the other postoperative pancreatic fistula subgroups.Conclusion: A subclassification of grade B postoperative pancreatic fistula can better stratify the increasing clinical burden and economic impact of postoperative pancreatic fistula after pancreaticoduodenectomy. Grade B1 postoperative pancreatic fistula has minimal clinical and economic consequences and can be considered closer to a biochemical leak than to a grade B2 postoperative pancreatic fistula.

Abstract

Background: Grade B postoperative pancreatic fistula represents the largest fraction of postoperative pancreatic fistula. A subclassification of grade B postoperative pancreatic fistula has been recently proposed and seems to better stratify postoperative pancreatic fistula clinical and economic burden. Aim of this study was to validate, from a clinical and economic standpoint, grade B postoperative pancreatic fistula subclassification in patients submitted to pancreaticoduodenectomy.Methods: All consecutive patients who underwent pancreaticoduodenectomy and developed biochemical leak or postoperative pancreatic fistula were included. Grade B postoperative pancreatic fistula was subclassified into 3 categories (B1: persistent drainage >21 days, B2: pharmacological treatments; B3: interventional procedures). Postoperative pancreatic fistula clinical and economic burden was assessed by evaluating postoperative complications, length of hospital stay, and overall hospital costs.Results: Overall, 289 patients developed biochemical leak or postoperative pancreatic fistula. Of these, 34 had biochemical leak (12%), 25 had grade B1 postoperative pancreatic fistula (9%), 91 had grade B2 postoperative pancreatic fistula (31%), 94 had grade B3 postoperative pancreatic fistula (32%), and 45 experienced grade C postoperative pancreatic fistula (16%). The severity of postoperative complications significantly increased across biochemical leak and postoperative pancreatic fistula categories (P <.001), but it was comparable between biochemical leak and grade B1 postoperative pancreatic fistula. There was no significant difference in terms of length of hospital stay between patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000). Overall hospital costs were similar for patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000), whereas they significantly increased across all the other postoperative pancreatic fistula subgroups.Conclusion: A subclassification of grade B postoperative pancreatic fistula can better stratify the increasing clinical burden and economic impact of postoperative pancreatic fistula after pancreaticoduodenectomy. Grade B1 postoperative pancreatic fistula has minimal clinical and economic consequences and can be considered closer to a biochemical leak than to a grade B2 postoperative pancreatic fistula.
