Abstract
OBJECTIVE: Morbid obesity is proinflammatory has been associated with adverse clinical outcomes in acute pancreatitis (AP) among adults. Obesity is increasingly prevalent in children and hence, we sought to evaluate the impact of morbid obesity on the clinical outcomes of AP using a large paediatric population-based cohort. METHODS: We analysed the US Kids' Inpatient Database between years 2003 and 2016 to include all patients (age ≤ 21 years) with a primary diagnosis of AP using specific ICD-9-CM and ICD-10-CM codes. We compared clinical outcomes between children without obesity (controls) and those with morbid obesity (cases). The primary outcome was severe AP (2012 revised Atlanta classification) and secondary outcomes included healthcare resource utilization (length of stay and hospital costs). RESULTS: Among 36 698 paediatric AP hospitalizations, 1275 (3.5%) were found to have morbid obesity. From 2003 to 2016, the proportion of children with morbid obesity among AP patients increased from 1.3% to 5.5% (P < .001). More than half (54%) of the children with morbid obesity were presented with cholelithiasis as contributive aetiology. The prevalence of severe AP was significantly higher in morbid obesity (7.3% vs 3.8%, P < .001). Multivariate analysis revealed that morbid obesity was increasingly associated with severe AP (OR 1.79, 95% CI 1.4, 2.26), prolonged hospitalization (by 0.41 days, P = .03), and higher hospital costs (by $1596, P < .001). CONCLUSION: Unlike adult population, there is a lack of other confounding comorbidities in children and this national-level analysis shows that morbid obesity independently prognosticates adverse clinical outcomes in paediatric AP.
