RESUMO
Chronic pancreatitis is a focal or diffuse chronic inflammation and fibrosis of pancreatic tissue, which is progressive, persistent and irreversible.Chronic pancreatitis in children has its own characteristics of early onset and frequent occurrence, which greatly affects the nutritional status and quality of life of children.Recently, diagnosis and treatment of this severe inflammation gradually improved with a burgeoning technique: endoscopic retrograde cholangiopancreatography (ERCP), especially in the treatment of pediatric chronic pancreatitis.The detection rate of the disease has been increasing year by year.As an effective and safe procedure for the treatment of chronic pancreatitis in children, ERCP has replaced traditional surgery and become the first-line treatment method for pediatric chronic pancreatitis.
