Aim. To compare the clinical characteristics of acute pancreatitis (AP) and recurrent acute pancreatitis (ARP) in children. Method. From January 2011 to January 2021, a total of 275 pediatric patients with AP admitted to a tertiary teaching hospital were enrolled. Results. The median age of 275 children was 12.0 years. Among them, 55 cases were ARP. The leading causes of pediatric pancreatitis were biliary tract and virus infection. The percent of male in the AP group was higher than that in the ARP group. Viral infection in the AP group were higher than that in the ARP group, but anatomical abnormalities were lower than those in the ARP group. The incidence of pancreatic pseudocysts in the ARP group was higher than that in the AP group. The median interval time from AP to ARP was 3.0 months. Conclusion. The main causes of pediatric pancreatitis were biliary tract and virus infection in the study. AP caused by virus infection seems to be less likely to develop into ARP. Female and anatomical abnormality are risks of ARP. Children with ARP are more likely to be complicated with pancreatic pseudocyst. There was no difference in ICU admission or mortality between AP and ARP.

儿童急性胰腺炎和复发性急性胰腺炎：10 年回顾性研究

瞄准。比较儿童急性胰腺炎（AP）和复发性急性胰腺炎（ARP）的临床特点。方法。2011年1月至2021年1月，共有275名三级教学医院收治的AP儿科患者入组。结果. 275 名儿童的中位年龄为 12.0 岁。其中55例为ARP。小儿胰腺炎的主要原因是胆道和病毒感染。AP组男性比例高于ARP组。AP组病毒感染率高于ARP组，但解剖异常低于ARP组。ARP组胰腺假性囊肿的发生率高于AP组。从 AP 到 ARP 的中位间隔时间为 3.0 个月。结论. 在研究中，小儿胰腺炎的主要原因是胆道和病毒感染。病毒感染引起的AP似乎不太可能发展成ARP。女性和解剖异常是 ARP 的风险。患有 ARP 的儿童更容易并发胰腺假性囊肿。AP 和 ARP 在 ICU 入院率或死亡率方面没有差异。
