Intraductal papillary mucinous neoplasms (IPMNs) can involve the main pancreatic duct (MD-IPMNs) or its secondary branches (BD-IPMNs) in a segmental of multifocal/diffuse fashion. Growing evidence indicates that BD-IPMNs are less likely to harbour cancer and in selected cases these lesions can be managed non operatively. For surgery, clarification is required on: (1) when to resect an IPMN; (2) which type of resection should be performed; and (3) how much pancreas should be resected. In recent years parenchyma-sparing resections as well as laparoscopic procedures have being performed more frequently by pancreatic surgeons in order to decrease the rate of postoperative pancreatic insufficiency and to minimize the surgical impact of these operations.

In this article the type and extension of surgical resections in patients with MD-IPMNs and BD-IPMNs are analyzed, evaluating perioperative and long-term outcomes.

Abstract

Intraductal papillary mucinous neoplasms (IPMNs) can involve the main pancreatic duct (MD-IPMNs) or its secondary branches (BD-IPMNs) in a segmental of multifocal/diffuse fashion. Growing evidence indicates that BD-IPMNs are less likely to harbour cancer and in selected cases these lesions can be managed non operatively. For surgery, clarification is required on: (1) when to resect an IPMN; (2) which type of resection should be performed; and (3) how much pancreas should be resected. In recent years parenchyma-sparing resections as well as laparoscopic procedures have being performed more frequently by pancreatic surgeons in order to decrease the rate of postoperative pancreatic insufficiency and to minimize the surgical impact of these operations. However, oncological radicality is of paramount importance, and extended resections up to total pancreatectomy may be necessary in the setting of IPMNs. In this article the type and extension of surgical resections in patients with MD-IPMNs and BD-IPMNs are analyzed, evaluating perioperative and long-term outcomes. The role of standard and parenchyma-sparing resections is discussed as well as different strategies in the case of multifocal neoplasms.
