Total pancreatectomy in a case of nesidioblastosis due to persisting hyperinsulinism following subtotal pancreatectomy.

Abstract

Hypoglycemia with hyperinsulinism persisted in a newborn weighing 6410 g despite treatment with high doses of diazoxide and glucagon, as well as infusions of glucose and somatostatin. A subtotal pancreatectomy was performed after nesidioblastosis had been diagnosed on the basis of the laboratory findings. Due to the persistence of therapy-resistant hypoglycemia, a total pancreatectomy preserving the duodenum and the bile duct was done 6 weeks later. With insulin and pancreatic enzyme substitution the now 6-year, 9-month-old child has shown normal, age, appropriate development.
