BACKGROUND: Pediatric acute pancreatitis (AP) is rare but increasing. Severe AP is associated with higher morbidity and mortality. However, there are no universally accepted prognostic criteria for AP. METHODS: This retrospective study included children with AP admitted to an intensive care unit (ICU) of our tertiary pediatric center between January 2009 and December 2018. The severity of organ dysfunction in AP was assessed according to the modified Atlanta criteria using the Pediatric Sequential Organ Failure Assessment (pSOFA) and Computed Tomography Severity Index (CTSI). RESULTS: Seventy acute episodes of AP were evaluated in 55 children with primary pancreatitis. In addition, secondary AP was diagnosed in 15 patients originally admitted to ICU for different indications. Mild AP [no organ dysfunction, normal computed tomography (CT) finding] was the most prevalent (64/85 episodes in 49 children), followed by moderate AP (15 children; pSOFA 2-9 points, CTSI 3-4 points on admission). Severe AP (pSOFA 4-17 points, CTSI 6-10 points) was diagnosed in 6 children with traumatic or secondary AP. The most frequent etiologies of primary AP episodes were idiopathic (39%) and biliary (31%). Children with idiopathic AP had frequent relapses and comorbidities. Hereditary AP was typically mild, but presented with high pancreatic enzyme levels and recurrence rates. Admission at ICU and an interval without enteral nutrition (EN) were relatively short in drug-induced AP and relatively long in secondary and traumatic AP. Endoscopic retrograde cholangiopancreatography (ERCP) was performed in 13 patients with biliary AP and in 4 patients with traumatic AP. No AP-related death was observed. CONCLUSION: pSOFA score accurately reflects the severity and prognosis of AP in children.
