Selective arterial calcium stimulation (SACST) with hepatic venous sampling was performed in 5 patients (3 female, 2 male; age range, 53–73 y) with recurrent endogenous hyperinsulinemic hypoglycemia caused by metastatic insulinoma between January 2004 and December 2014. The biochemical results of SACST confirmed functional hepatic metastases alone (n = 3), peripancreatic lymph-node and hepatic metastases (n = 1), and occult insulinoma in the pancreatic bed (n = 1), thereby helping to guide management. SACST may be useful to determine the extent of functional metastatic insulinoma, particularly within the liver, and may provide clinicians with additional information to help guide the multidisciplinary management of patients with recurrent endogenous hyperinsulinemic hypoglycemia.
