Pediatric pancreatic pseudocysts (PPPs) are mainly caused by acute and chronic pancreatitis, pancreatic trauma, and pancreatic duct obstruction, but are relatively rare in pediatric patients. Trauma and pancreatitis account for 60 % and 30 % of pancreatic pseudocysts (PPs), respectively, while unknown causes account for 10 %.1 Rupture of the pancreatic parenchyma or pancreatic duct after blunt pancreatic trauma can lead to the accumulation of leaked pancreatic fluid, exudate, necrotic tissue, and blood in the retroperitoneal space, which can stimulate inflammatory responses of the tissues around the pancreas and hyperplasia of fibrous connective tissue, resulting in fibrous effusion wrapped in a pseudomembrane (incidence of up to 44 %).2 At present, the therapeutic principle for PPPs mainly refers to the guidelines for adult PP, which include conservative treatment, ultrasound-guided percutaneous drainage, traditional surgery (internal and external drainage with cyst excision), and endoscopic- or laparoscopic-guided drainage. However, it is crucial to select an appropriate treatment regimen based on the condition of the patient and disease etiology. Here, the outcomes and treatment experiences of 62 PPPs at the Children's Hospital of the Zhejiang University School of Medicine were retrospectively reviewed.
