Objectives: The aim of this study was to describe the epidemiological characteristics of acute recurrent pancreatitis (ARP) among children who were admitted at Childrens Hospital 2, Ho Chi Minh City, Vietnam, from May 2014 to May 2019. Methods: Authors presented Case series study. Results: A total of 33 cases met the criteria for study inclusion. The mean age of first onset 7.3 ± 4.4 years (range, 1.415 years), the male to female ratio was 18:15 (1.2:1). The median number of ARP admissions per patient was 3 (range, 214), and the median time between ARP-related hospitalization was 168 days (range, 82240 days). The chief complaint upon hospitalization was abdominal pain, accounting for 96.9% of cases, vomiting in 87.9% of cases, and severe ARP was observed in 24% of cases. All patients underwent magnetic resonance cholangiopancreatography (MRCP), and abdominal computed tomography (CT) scans. Genetic testing was performed in 14 of 33 cases, and 5 cases had at least 1 mutation, whereas 9 were negative. The most common etiology of ARP was biliary tract disease, in 17 cases (51.5%; 11 choledochal cysts, 6 gallstones), abnormalities of the pancreas were observed in 18.2% (abnormalities of pancreatic structures in 3 cases), hypertriglyceridemia and metabolic disease were observed in 6.1% of cases, and genetic mutations were identified in 15.2% of cases. Conclusion: ARP is not a rare disease, and ARP patients may be admitted to the hospital many times. The chief complaints resulting in hospitalization were abdominal pain and vomiting. The most common causes were biliary tract diseases (bile duct cysts in 33.3% and gallstones in 18.2% of cases), with abnormalities of the pancreatic structure identified in 9.1% of cases, and genetic mutations detected in 15.2% of patients.
