- Abstract
- The mortality of severe acute pancreatitis still ranges between 10% and 20%. Nowadays, infected pancreatic necrosis is the leading cause of death. Despite advances in intensive care therapy, however, early and worsening multi-system organ failure remains a source of substantial morbidity and still accounts for 20-50% of the deaths. News and hotspots - The three interrelated pathophysiological mechanisms underlying glandular necrosis include the premature intra-acinar activation of pancreatic pro-enzymes, an early pancreatic microcirculatory impairment, and the excessive stimulation of immune effector cells. In recent years, the systemic inflammatory response syndrome and the relevant cascades of inflammatory mediators have been implicated as the key factor in the emergence of remote tissue damage. Early multi-system organ failure that supervenes in the first week is typically associated with a sterile necrotizing process. The correlation between pathomorphological and clinical severity and the similarity between their respective pathophysiological mechanisms are not straightforward, however. There are no pathophysiological, clinical or economical data to support the practice of debridement of sterile necrosis to prevent or to control early multi-system organ failure. This issue has never been addressed in a controlled study. Besides intensive care support, non-surgical therapeutic modalities including urgent endoscopic sphincterotomy for impacted stones, antibiotic prophylaxis for the prevention of pancreatic infection and early jejunal nutrition have been specifically developed hopefully to attenuate multiple organ failure, to obviate the need of surgical drainage and to improve survival. Fine needle aspiration of necrotic areas must be incorporated in any conservative therapeutic strategy in order not to jeopardize those with infected necrosis that remains an absolute indication for drainage. Perspectives - There is ample experimental and pathophysiological evidence in favour of immunomodulatory therapy in severe acute pancreatitis. The administration of one or several antagonists of inflammatory mediators possibly combined with a protease inhibitor may at last provide the opportunity to interfere with the two major determinants of prognosis: the severity of multiple organ failure and the extent of necrotic areas that creates the culture medium for bacterial superinfection. These benefits remain to be substantiated in a controlled study, however. © 2003 Éditions scientifiques et médicales Elsevier SAS. Tous droits réservés.
