title: Near-total pancreatectomy for hyperinsulinism. Spontaneous remission of resultant diabetes.
abstract: Persistent hyperinsulinism in the newborn may warrant surgical intervention to prevent neurologic sequelae. Subtotal pancreatectomy may not be adequate, necessitating near-total pancreatectomy with subsequent development of diabetes mellitus. We report an infant with hyperinsulinemic hypoglycemia who underwent near-total pancreatectomy. The postoperative period was characterized by insulin-dependency and extreme insulin sensitivity. Clinical follow-up and C-peptide determinations showed a return of insulin secretory capacity permitting the discontinuation of insulin therapy after five months. This experience reaffirms the potential for a favorable outcome after near-total pancreatectomy in the newborn period for severe hyperinsulinism.
