AIM: to evaluate etiological agents involved in acute pancreatitis in children, as well as clinical, laboratory and radiological findings and the illness clinical course. PATIENTS AND METHODS: we reviewed the cases of acute pancreatitis diagnosed over the last 15 years. The criteria used for cases to be included were acute abdominal pain, elevated serum amylase levels and/or ultrasound abnormalities in the pancreatic area in conscious patients, and the last two criteria in unconscious patients. RESULTS: thirty-one children were included (average age 7.9 years, range 2-15; 55% males). Infection and gallstones were the most common causes (19 and 16 %, respectively). In all, 9.7% of cases were drug-related (valproic acid, L-asparaginase, azathioprine combined with high doses of methylprednisolone); 6.5% were traumatic in origin and another 6.5% was due to systemic diseases. In 35.5 % no cause was found (idiopathic). The most frequent symptoms were abdominal pain (90%) and emesis (38%). Amylase serum levels were elevated in all patients. Abdominal ultrasound scans were abnormal in 64%, with an increase in the pancreatic area in 48% and hypoechogenicity in 51%. Seven cases required surgical treatment (22%). Seven children had acute pancreatitis, and three of them died as a result of shock unrelated to pancreatitis. Relapse of disease occurred in 19% of patients. CONCLUSIONS: acute pancreatitis should always be considered in children with abdominal pain. There are a wide variety of etiological factors and in a high percentage of patients no underlying cause is found. Prognosis is variable owing to the heterogeneity of the clinical course of this illness in children.
