^aNote that some studies include cystic asymptomatic pancreatic lesions only, whereas others include both solid and cystic; ^bMCN/SCN included together here; ^cStudy included only Whipple's by design. IPMN: Intraductal papillary mucinous neoplasm; MCN: Mucinous cystic neoplasms; SCA: Serous cystadenomas.
