Acute Pancreatitis in Children: It's Not Just a Simple Attack

Acute pancreatitis (AP) in children presents unique challenges distinct from adult manifestations, requiring specialized diagnostic and therapeutic approaches. Compared with adults, pediatric AP has lower mortality rates but still carries significant morbidity and potential long-term complications. This review examines current evidence on pediatric AP, highlighting recent advances in diagnosis, risk stratification, and management strategies. Current diagnostic approaches use serum lipase and amylase testing, along with various imaging modalities that have different diagnostic values. Recent research has identified promising biomarkers for predicting severe AP, including blood urea nitrogen, C-reactive protein, and specific cytokine signals. Emerging evidence suggests a role of gut microbiome dysbiosis in disease pathogenesis, opening new therapeutic possibilities targeting the gut-pancreas axis. Genetic factors, specifically pancreatitis risk genes, influence disease progression to recurrent and chronic pancreatitis. In this review, we summarize the consequences of an isolated AP episode in children. Our review highlights for the first time how AP can lead to significant long-term sequelae, including exocrine/nutritional deficiencies, endocrine pancreatic dysfunction, diabetes, recurrent pain, and decreased quality of life compared with healthy population controls. The goal of this review is to summarize advances in understanding of pediatric AP and to emphasize the importance of early recognition, appropriate risk stratification, and comprehensive follow-up after the first pediatric AP episode, while highlighting areas requiring future research to optimize patient outcomes.
