[Clinical characteristics and prognosis of 227 children with acute pancreatitis].

OBJECTIVE

To analyze the clinical characteristics and prognosis of acute pancreatitis (AP) in children, and provide reference for clinical prevention and treatment of AP in children.

METHODS

Based on the electronic medical record system of the Affiliated Hospital of Zunyi Medical University, the clinical data of children with AP in the hospital from January 2011 to December 2020 were retrospectively analyzed. According to the severity of the disease, the children were divided into mild acute pancreatitis (MAP) group and severe acute pancreatitis (SAP) group. The general data, laboratory tests and outcomes indicators of the two groups were collected and compared. The epidemiological characteristics of children with AP were analyzed. Multivariate Logistic regression was used to analyze the risk factors of SAP in children.

RESULTS

A total of 227 children with AP were enrolled, including 161 in MAP group and 66 in SAP group. The median age of children with AP was 12.00 (8.00, 16.00) years old, and 126 cases (55.51%) were male. The main initial clinical symptoms were abdominal pain, nausea, vomiting and abdominal distension (97.36%, 61.67% and 14.10%, respectively), 21 cases (9.25%) were admitted to intensive care unit (ICU), and 4 cases (1.76%) died in hospital due to sepsis, multiple organ dysfunction or traumatic shock. The epidemiological characteristics showed that the first onset age of AP was mainly 7-17 years old (85.02%); the main etiologies were biliary tract disease (29.96%), viral infection (29.07%) and idiopathic factors (19.82%). From 2011 to 2020, the number of children with AP showed a fluctuating trend, and from 2018 to 2020, the number of children with AP increased for three consecutive years. Compared with MAP group, the age of SAP group was significantly older, the proportion of female, the proportion of rural source, acute physiology and chronic health evaluation II (APACHE II), body mass index (BMI), and the levels of white blood cell count (WBC), C-reactive protein (CRP), hospitalization expenses, the proportion of AP caused by traumatic factors and drug factors in SAP group were significantly higher (all P < 0.05). The level of blood calcium and the proportion of AP caused by virus infection were significantly lower, and the length of hospital stay in SAP group was significantly longer (all P < 0.05). The multivariate Logistic regression analysis showed that APACHE II score [odds ratio (OR) = 1.495, 95% confidence interval (95%CI) was 1.293-1.728] and age (OR = 1.352, 95%CI was 1.182-1.546) were closely related to SAP in children (all P < 0.001).

CONCLUSIONS

Children with AP mostly occurs in preschool and adolescence, and the overall mortality is relatively low; biliary tract disease, viral infection and idiopathic factors are common causes; APACHE II score and age may be risk factors for SAP in children.
