Background: Postoperative pancreatic fistula is currently the most frequent complications after duodenopancreatectomy. There are currently no RCT comparing two of the most frequently used method of pancreato-enteric anastomosis (invaginating pancreatogastric anastomosis versus Blumgart anastomosis)~Hypothesis: in patients with resectable pancreatic and periampullary tumors, performing a Blumgart (AB) anastomosis for pancreatoenteric reconstruction after duodenopancreatectomy decreases the rate of postoperative pancreatic fistula (PPF) compared to to pancreatogastric anastomosis.~Main goal: To comparatively evaluate the rate of PPF in patients with pancreatic and periampullary tumors undergoing cephalic duodenopancreatectomy after reconstruction with Blumgart anastomosis or pancreatogastric anastomosis.
A national, multicenter, randomized, prospective, parallel group clinical study to evaluate two therapeutic strategies (invaginating pancreatogastric anastomosis versus Blumgart anastomosis).
