Grand Round Webinar: Pancreatitis in children: Why early diagnosis matters

Rising Threat in Paediatric Pancreatitis

Paediatric acute pancreatitis, inflammation of the pancreas causing intense abdominal pain, vomiting, and potential systemic complications, was long considered uncommon in children. Recent analyses from the Global Burden of Disease Study show incidence rising globally among those aged 0-24, with cases increasing from roughly 156,000 in 1990 to nearly 195,000 in 2021, and age-standardised rates edging up despite falling mortality thanks to improved care.

This uptick stems partly from heightened clinical awareness and diagnostic advances, including routine enzyme testing and imaging, which capture cases once overlooked. Contributing factors also include rising childhood obesity, which promotes gallstones and hypertriglyceridaemia, both established triggers. In some cohorts, obesity alters metabolic responses during attacks without necessarily worsening severity, yet it adds to the overall pool of at-risk children.

The condition affects children variably: biliary issues, genetic mutations like SPINK1 or PRSS1, infections, and anatomical defects rank among common causes, while many remain idiopathic. Up to a third of affected children experience multiple episodes, and recent longitudinal data highlight substantial risks—around 20% recur after one attack, with over a third of those advancing to chronic pancreatitis, marked by persistent pain, exocrine insufficiency, and endocrine failure.

Stakes are concrete: severe episodes can lead to necrosis, fluid collections, or organ failure, with hospital stays and intensive care needs. Progression to chronic forms imposes lifelong management costs, nutritional deficits, and heightened pancreatic cancer risk later. Inaction on early signs—often nonspecific abdominal pain—delays genetic or structural evaluations, missing windows for preventive steps like enzyme supplementation, which recent studies suggest cuts recurrence in some.

Tensions exist between over-diagnosis in mild cases and under-recognition in idiopathic ones, where pancreatitis may signal underlying conditions like early inflammatory bowel disease. Regional variations persist, with higher burdens in areas like Eastern Europe or South Asia linked to local risk profiles, though Western trends show steady increases tied to lifestyle factors. Mortality has declined overall, yet the growing incidence signals a mounting challenge for paediatric systems already stretched by obesity epidemics.
