Editorial
Te term incidentalomas means a non-symptomatic lesion, detected during imaging or
biochemical studies for unrelated causes. Te constant improving of high-quality imaging has
increased the number of asymptomatic solid or cystic masses that can be detected. Te most
common incidentalomas described in literature are located in the adrenal gland, thyroid, liver, heart
and prostate. Teir prevalence and their management are well described and largely accepted [1].
Among these, Pancreatic Incidentalomas (PI) are becoming more and more common, but data
regarding their prevalence and treatment strategy are still poor and consequently some aspects of
their management are still debated.
According to the current literature, PI prevalence is 10% in the adult population, reaching 30%
in the elderly [2]. Tey are usually detected during workups for non-pancreatic symptoms or follow-
ups for other malignant pathologies.
The biological nature of PIs is represented by a wide range of neoplasms: Pancreatic Ductal
Adenocarcinoma (PDAC), Intraductal Papillary Mucinous Neoplasms (IPMN), Mucinous Cystic
Neoplasms (MCN), Serous Cystadenomas (SCA), Non-Functional Neuroendocrine Tumors (NET),
Acinar Cell Carcinoma (ACC) and Solid Pseudopapillary Neoplasm (SPPN) [3,4]. In a case series
published by Lahat et al. [1] PDAC was the most common finding among PIs, followed by IPMN
and MCN.
Although they present with no symptoms related, these lesions can be premalignant or even
already malignant. PIs could be categorized into solid and cystic lesions. Cystic PIs frequently
show a benign or premalignant nature while solid PIs are usually considered malignant masses.
According to recent studies, size >20 mm and biliary dilatation are related to malignancy and, when
simultaneously present, the frequency of malignancy is above 90% [5]. It is important to underline
that pancreatic adenocarcinomas located in the head of the gland are more frequently
symptomatic than body and tail neoplasms. They are responsible for jaundice, main pancreatic
duct dilatation and its related symptoms such as endocrine and exocrine pancreatic insufficiency.
The detection of asymptomatic lesions represents also a significant issue in those individuals
with strong family history of PDAC. These are patients with an inherited predisposition, like
Peutz-Jeghers syndrome, family breast and ovarian cancer and hereditary nonpolyposis colorectal
cancer, who could benefit a screening program. Canto et al. [6] recently demonstrated that
screening programs for these asymptomatic patients could easily detect small pancreatic lesions. In
these cases MRI and endoscopic ultrasonography detect PIs better than CT [6].
Since not all lesions have malignant potential, the operative strategy could be complex and
surgeons must consider the risks and benefits of performing a potentially morbid operation for a
possible benign condition [7].
It is well-known that surgical treatment for pancreatic lesions is characterized by high rate of
mortality and morbidity. Mortality after a pancreaticoduodenectomy (PD) procedure is reported
as 1% to 3% in high volume centers and up until 10% in smaller ones [8], while morbidity
concerns about 30% to 40% of patients [9]. The most frequent sources of postoperative morbidity
include postoperative hemorrhage, delayed gastric emptying, postoperative pancreatic fistula and
intra-abdominal abscess [10].
