Abstract
Introduction. Congenital hyperinsulinism (CHI) is an inherited disease characterized by severe persistent hypoglycemia in the neonatal period due to insulin hypersecretion and rapid development of neurologic and systemic disorders. There are two main CHI forms: a diffuse one when hyper functioning of beta-cells affect the whole pancreas, and a focal one, characterized by an area of intact parenchyma. Currently, surgery is an acknowledged approach in focal forms, while in diffuse CHI forms surgical treatment is prescribed only in severe pharmacoresistant cases.Material and methods. A total of 11 patents with CHI, aged 1.5 - 26 months, had laparoscopic pancreatic resections at the department of pediatric surgery of Russian Medical Academy of Continuous Professional Education. All patients were examined , treated and prepared for surgery at the Endocrinology Research Centre ( Moscow). The focal CHI form was diagnosed in 3 children; the diffuse one - in 8 patients. In the focal CHI form, a focal resection was done: laparoscopic corpocaudal resection of the pancreas – 2 patients; resection of the pancreatic head with Roux–en-Y pancreaticojejunostomosis - 1 child. All children with diffused disease had laparoscopic near-total (98%) pancreatectomy.Results. In all cases, there were no intraoperative complications. Stenosis of the distal common bile duct developed in one child after the resection of pancreatic head which required a laparoscopic cholecystoduodenoanastomosis. There were no other complications. Two children with focal CHI were reported to recover completely; one patient suffered of hypoglycemia attacks not related to the increased insulin production. In diffuse cases, a stable euglycemia was achieved in 2 patients; 3 children had recurrent hypoglycemia attacks which required Somatostatin analogue therapy. One patient developed diabetes mellitus. In this case, follow-up period lasted for 2 months which is too short to assess the endocrinological outcome.Conclusion. The article presents the first Russian experience of laparoscopic pancreas resection in children with CHI. The laparoscopic approachcan be successfully applied in the surgical treatment of children with CHI.
