Clinical analysis of 29 cases of chronic pancreatitis in children / 中华实用儿科临床杂志

ABSTRACT

Objective To investigate the etiology and clinical characteristics of chronic pancreatitis (CP) in children,so as to improve its diagnosis and treatment.Methods The etiology,clinical characteristics,radiological records and therapy were retrospectively analyzed in children with CP who were admitted to Beijing Children's Hospital Affiliated to Capital Medical University from July 2006 to May 2014.Results A total of 29 medical records of children with CP,including 19 male and 10 female,with a mean age of (8.5 ± 3.7) years,and the youngest case was a 2-year-old child,the oldest case was a 15-year-and-2-month-old child.The main etiological factor was idiopathic pancreatitis (51.7％,15/29 cases),and 9 cases were caused by anatomical anomalies (31.0％,9/29 cases).The main symptoms included abdominal pain (89.7％,26/29 cases),malnutrition (48.3％,14/29 cases),nausea and vomiting (31.0％,9/29 cases),and chest distress and dyspnea (17.2％,5/29 cases).The serum amylase level in 18 cases (62.1％) increased.The positive diagnostic rate of transabdominal ultrasound was 96.6％ (28/29 cases),and dilations of pancreatic ducts or/and intraductal stones were 82.8％ (24/29 cases).The positive rate by magnetic resonance cholangio-pancreatography (MRCP) for morphological changes in pancreas was 88.5％ (23/26 cases),and dilations of the pancreatic ducts were 80.8％ (21/26 cases).A total of 10 endoscopic retrograde cholangio-pancreatography (ERCP) procedures were performed on 6 children,and pancreatic ductal stenosis or dilations were detected in them.All the patients were treated conservatively at first,and then 7 cases of them had surgical therapy (oledochojejunostomy,choledochoduodenostomy,choledochocystectomy,etc.),aud 6 cases had stent insertion by ERCP.Conclusions The main causes of CP in children are idiopathic and anatomical anomaly,and its diagnosis is based on symptoms and imaging changes;surgical or endoscopic therapy can be used if internal therapy is not effective.
