OBJECTIVE: Pancreatic cystic tumors are relatively rare tumors and only 1% of them are malignant. They are often asymptomatic and detected as incidental findings through diagnostic imaging. Currently there are no universal guide lines for the correct clinical approach to pancreatic cystic lesions. Cross-sectional imaging demonstrates some typical morphological features that determine the pre-operative diagnosis of the pancreatic cystic lesions (serous or mucinous cystadenoma, intraductal papillary mucinous neoplasms). In addition, endoscopic ultrasonography permits the collection and analysis of the fluid content. The aim of this paper is to describe our case load in the management of pancreatic cystic neoplasms and propose some criteria for choosing between surgical or conservative approaches.

PATIENTS AND METHODS: 12 patients with pancreatic cystic neoplasms were retrospectively evaluated. They were studied using cross-sectional imaging modalities (computed tomography and magnetic resonance); endoscopic ultrasonography was performed in 7 patients.

RESULTS: In each patient a careful evaluation of several factors (age, comorbidity, imaging features, symptoms, life expectancy) conditioned our clinical decision. Among our 12 patients, surgical resection was performed in 7 cases.

DISCUSSION: The treatment of pancreatic cystic lesions is still a dilemma because even in the presence of malignant potential, pancreatic surgery remains very complicated and demolitive.
Many factors need to be considered in the management of cystic pancreatic tumors. The most important include histological type, location, size, age and clinical condition of the patient.

CONCLUSIONS: A correct multidisciplinary pre-operative diagnosis is mandatory. Surgery should only be performed in selected cases.
