The aims are to determine: – The risk of deterioration in the long term (main objective); – Morphological factors predicting deterioration (secondary aim) – Subgroups of patients at risk of deterioration based on their sociodemographic, clinical, morphological and molecular characteristics (secondary aim). null France Individuals Patients population Male Female Young Adult (19 to 24 years) Adult (25 to 44 years) Middle Aged (45 to 64 years) Aged (65 to 79 years) Aged, 80 and over (80 years and more) – IPMN only in the secondary ducts; – No signs of malignant transformation of IPMN lesions; – Main pancreatic duct no more than 6 mm in diameter; – Presence of residual IPMN lesions in the secondary ducts for patients with a history of IPMN surgical resection. All patients with diagnosed secondary-duct IPMN before TEAM-P study was begun may be included.
