Abstract:In 2025, the International Association of Pancreatology (IAP), in collaboration with the American Pancreatic Association, European Pancreatic Club, Indian Pancreas Club, and Japan Pancreas Society, released the International Association of Pancreatology revised guidelines on acute pancreatitis 2025. This edition represents a comprehensive revision of the 2013 guidelines, based on high-quality evidence accumulated over the past decade, particularly randomized controlled trials. The guidelines encompass 18 key areas-including pain management, fluid therapy, nutritional support, management of infected necrosis, complication control, discharge and follow-up, and recurrence prevention-offering a total of 96 recommendations that emphasize individualized treatment. These updates provide important guidance for standardizing clinical practice and improving outcomes in acute pancreatitis, while also indicating future research directions such as the development of targeted therapies. However, some recommendations remain limited by lower evidence quality, uncertain applicability in specific clinical settings, and insufficient consideration of economic burden and cost-effectiveness.
