Potential pitfalls in the management of primary pancreatic cystic neoplasms

Primary pancreatic cystic neoplasms (PCN) have been increasingly recognized over the last 2 decades, mainly as a result of the widespread use of modern imaging techniques in patients with abdominal complaints. Biological behavior and management greatly differ between subgroups of PCN. Accurate preoperative diagnosis is required to select the optimal management strategy for each individual patient with PCN. An in-depth knowledge of the biological, imaging, macroscopic/microscopic features, and laboratory findings of each subtype of PCN is required on the part of the clinician, in order to select a cost-effective diagnostic evaluation of the patient. Clinical judgment is also required on the part of the surgeon to select the optimal procedure and to avoid severe pitfalls in the surgical management of these neoplasms.
