Disease-specific survival of patients minimal involvement of the main pancreatic duct (min-mix-IPMN), extensive involvement of the main pancreatic duct (ex-mix-IPMN), branch-duct type IPMN (BD-IPMN), and main-duct type IPMN (MD-IPMN). The 5- and 10-year survival rates after resection were 97% and 97%, respectively, in min-mix-IPMN patients, better than those of ex-mix-IPMN patients (83% and 83%, respectively; P = .046), but similar to those of BD-IPMN patients (95% and 94%, respectively; P = .67). Survival rates of MD-IPMN did not differ from those of ex-mix-IPMN (5-year, 69% vs 83%; 10-year, 69% vs 83%; P = .40).
