Long-term complication following subtotal pancreatectomy for nesidioblastosis: a case report.

Nesidioblastosis is the most common cause of neonatal hypoglycemia. Although medical therapy has been attempted, it is generally accepted that these infants should undergo a subtotal to near total pancreatectomy with splenic preservation. Complications from this procedure have been few, most commonly those associated with decreased insulin production (diabetes). We describe a case of a young, white male who presented with complaints of hematemesis and melena 18 years following subtotal pancreatectomy for nesidioblastosis.
