**Abstract**

The incidence of acute pancreatitis is increasing in children and it should be considered as part of differential diagnosis in case of abdominal pain. The etiology of acute pancreatitis in this subpopulation is related to several conditions and risk factors, such as drugs, obesity, infections, trauma and anatomic abnormalities. In older children abdominal pain is the first symptom in more than 90% of cases, where as in younger children vomiting represents an early clinical manifestation. Diagnosis is based on laboratory investigation, such as serum levels of lipase, and imaging findings (ultrasonography, CT scanning or MRI) such as detecting edema, hemorrage or necrosis of pancreatic parenchyma or in peripancreatic fat. Treatments for adults and children are similar. Rapid and accurate assessment of the severity of pancreatitis is absolutely indicated for selecting the appropriate treatment and predicting the prognosis.
