The term “nesidioblastosis” has been used to denote histopathological findings such as neogenesis from pancreatic ductal epithelium in parallel with β-cell hyperplasia and hypertrophy (1). This entity was first described in children and neonates and is characterized by endogenous hyperinsulinemic hypoglycemia. The incidence rate in adults ranges between 0.5 and 7 %. The pathophysiological mechanisms in adults are ill-defined.

The preoperative distinction between insulinoma and nesidioblastosis is of primordial importance since the therapeutical strategies are different, ranging from a enucleation in the case of insulinoma up to a 70–80 % pancreatectomy in the case of nesidioblastosis. Clinically, the distinction between insulinoma and nesidioblastosis is not always possible.

Preoperative imaging including MRI, CT, and endosonography is not diagnostic in adult nesidioblastosis, and invasive investigation using selective arterial calcium stimulation and venous sampling (ASVS) is...
