[Somatostatin in a case of neonatal hyperinsulinism caused by focal adenomatosis of the head of pancreas].

The use of somatostatin in the treatment of a newborn infant with hyperinsulinism is reported. When administered alone, somatostatin was only able to prevent hypoglycemia for a short period of time, whereas the addition of a constant infusion of glucagon allowed successful control of the patient's hypoglycemia. As hyperinsulinism relapsed after a subtotal pancreatectomy, a trial was carried out with a somatostatin analog, which has an expected longer duration of action. It led to a significant rise in the blood glucose level but failed to prevent safely hypoglycemia even when 4 injections were performed daily.
