The surgical approach to congenital hyperinsulinemia is also of great concern to parents. Depending on the histological type of the pancreas of the child, there are two main surgical procedures for congenital hyperinsulinemia: partial pancreatectomy and subtotal pancreatectomy. The former is indicated for children with focal CHI, where only the part of the pancreas containing the focal lesion is removed, and the prognosis is generally better for this type of patient. Subtotal pancreatectomy is indicated for children with diffuse CHI, requiring resection of approximately 95-97% of the pancreas. The surgical outcome and postoperative regression of children with this type of CHI are more complicated, and long-term clinical observation and follow-up are still needed after surgery.
