#50 Clinical-morphology correlation in diagnostics and evaluating surgery results of pancreatic insulinoma and nesidiobastosis

Introduction: Organic hyperinsulinism syndrome (OHS) is revealed in 85% cases of pancreas insulinoma. Nesidioblastosis (NB) induces OHS in 15% of the cases. Surgical cure provides all symptoms of insulinoma disappearing, while cytoreductive operation results in considerable improvement of life quality. There is no intraoperative opportunity to reveal insulinoma grade, even if an urgent biopsy is performed. Thus, it is essential to determine the cause of OHS and to apply the surgical cure method during the preoperational period, thereby improving the long-term prognosis.
