Is 95% pancreatectomy the procedure of choice for treatment of persistent hyperinsulinemic hypoglycemia of the neonate?
A 95% pancreatectomy became the treatment of choice for persistent hyperinsulinemic hypoglycemia of the neonate (PHHN, Nesidioblastosis) at the author’s institution, when lesser resections failed to prevent hypoglycemia in 25% to 50% of cases. With few outcome data available in the literature, the authors reviewed their 25-year experience to assess the efficacy and the long-term consequences of this procedure. Since 1971, 27 infants underwent a 95% pancreatectomy for the treatment of PHHN. None had responded to medical treatment (glucose infusion, glucagon, octreotide, diazoxide), and two had 85% pancreatectomy that failed. The procedure consisted of resecting the pancreas including the uncinate process, leaving only the gland lying between the common bile duct (CBD) and the duodenum and a small rim of pancreas along the duodenal sweep. Hyperinsulinemia and hypoglycemia recurred in nine children (33%), all within 2 to 5 days. Seven of them were subsequently cured with near-total pancre
