Immunoparalysis After Pancreaticoduodenectomy

By 2030, pancreatic adenocarcinoma could become the second leading cause of cancer-related death in France. To date, Pancreaticoduodenectomy (PD) is the standard treatment for resectable adenocarcinoma of the pancreatic head. Despite advances in perioperative care, morbidity remains high, and the occurrence of postoperative complications can negatively impact patient's oncologic prognosis. Sepsis is the leading cause of postoperative death following PD and it remains mainly associated with the development of a clinically-relevant postoperative pancreatic fistula (CR-POPF). More recently, post-pancreatectomy acute pancreatitis (PPAP) has been defined as a very early complication after pancreatic resection. PPAP is an ischemic and inflammatory condition of the pancreatic remnant that may be responsible for nearly half of CR-POPFs. CR-PPAP can lead to sepsis with multiorgan failure and necrotizing pancreatitis, which are with CR-POPF the two main indications for reoperation and completion pancreatectomy. Despite the major impact of severe pancreatic complications on mortality after PD, no reliable early biomarker currently exists to predict their occurence. Immunoparalysis refers to the functional impairment of immune cells with monocytes showing altered capacity of cell presentation. In classical models of inflammation such as acute pancreatitis, sepsis and surgery, the initial systemic inflammatory response syndrome is simultaneously accompanied by a compensatory anti-infla…
