Pancreas cystic neoplasm consist of about 30% of all resected pancreatic tumor. There is a trend towards increasing resection of pancreatic cystic neoplasms. This trend may be explained by the increased use of imaging studies and advancements in imaging technologies. In addition, routine health checkup is becoming more popular which inevitably leads to increased incidental detection of cystic neoplasms. The prevalence of asymptomatic pancreatic cystic neoplasm is reported to be up to 19.6%
Intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), and serous cystic neoplasm (SCN) are representative true cystic neoplasms. The malignancy rate of IPMN can be as high as 60% and that of MCN is known to be between 15 to 30%. On the other hand, SNCs are known to be mostly benign and the malignancy in SCN is very rare. Because of this difference in malignancy potential, differentiating these cystic tumors on preoperative image studies is very important in order not to overtreat SCNs nor to undertreat IPMNs or MCNs.
The prevalence of SNC is 1 to 2% of all pancreatic tumors and 10 to 29% of pancreatic cystic tumors. Because of the benign nature of SCN, the observation policy is usually adequate. However, there are certain circumstances that require surgical resections for SCN. The reasons for surgical resection of SCNs is very simple and rather straight forward.
Although very uncommon, there are case reports indicating possible malignant transformation of SCNs. In cases where malignancy is suspected resection is required. In addition, SCNs that cause mechanical symptoms such as pain, bowel obstruction, biliary obstruction, or pancreatitis needs to be resected as a mean to relieve the patient of the symptoms.
Beside to the indications mentioned above, the resection of SCNs are more commonly caused by atypical radiologic findings that make differentiation of SCN from other malignant or borderline cystic tumors very difficult.
In this lecture, we will review the relative infrequent serous cystic neoplasm in overall. Further, clinical and radiologic features of the SCNs that undergo resection.
