BMI = body mass index. ASA = American Society of Anesthesiologists’ risk class

^*Benign pancreatic tumor includes intraductal papillary mucinous neoplasms, mucinous cystic neoplasms and serous cystadenomas

^**Normal pancreas indicates operation was performed for pathology elsewhere and pancreas was removed to ensure negative margins.
