ABSTRACT
Hyperinsulinaemic hypoglycaemia [HHI] is the most frequent aetiology of recurrent severe hypoglycaemia in newborn and infant. This pathology arises the problem of early medical and surgical management to prevent brain damage. The aim of this work is to stress on the treatment emergency, to underline difficulties to distinguish damage. The aim of this work is to stress on the treatment emergency, to underline difficulties to distinguish between focal forms and diffuse forms, and to discuss our results with literature data. Our work is a retrospective study of 3 observations of symptomatic newborn HHI. Due to failure of glucose supplementation and medical treatment based on diazoxide and hydrocortisone, the 3 patients were operated between 50 and 107 days of life. Surgical exploration did not find any macroscopic pancreatic abnormality and intervention consisted of subtotal pancreatectomy [90-95 percent]. Anatomopathological study showed diffuse form in 2 cases and focal form in one case. After a follow up of 3 months to 2 years and a half the 3 patients have a normal glycaemia with no need to medical treatment. Yet 2 patients present brain damages .HHI is an emergency which needs a rapid medical management. Medical treatment failure should lead quickly to surgery to prevent neurological complications
