The aim of this randomized controlled study is to compare the efficacy of biodegradable internal pancreatic stenting versus no stenting in patients undergoing pancreatoduodenectomy (PD), focusing on a possible superiority association of the device in preventing clinically relevant postoperative pancreatic fistula (CR-POPF). Patients undergoing PD will be randomized into two arms: * arm 1: a biodegradable internal pancreatic stent will be placed at the level of the pancreatic anastomosis * arm 2: no pancreatic stent will be placed at the level of the pancreatic anastomosis The rate of occurrence of CR-POPF will be compared between the two arms.
