Congenital hyperinsulinism (CHI) is a cause of severe and persistent hypoglycaemia due to unregulated insulin secretion from pancreatic β-cells. Mutations in the ABCC8 and KCNJ11 genes are the most common cause of medically unresponsive CHI. Histologically there are three major subgroups, focal, diffuse and atypical. The pathophysiology of focal CHI is complex and involves a two hit process with the patient firstly inheriting a paternal ABCC8/KCNJ11 m...

Background: Congenital hyperinsulinism (CHI) is cause of severe hyperinsulinaemic hypoglycaemia in the neonatal and infancy periods. Histologically there are three major subgroups, diffuse, focal and atypical. Patients with diffuse CHI who are medically unresponsive will require a near total pancreatectomy. This has traditionally been performed using an open surgical approach.Aims: To report our experience of laparoscopic near total pancreatectomy for me...

Introduction: Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycaemia in infants and children. Histologically there are two subgroups, diffuse and focal. Fluorine-18-L dihydroxyphenylalanine positron emission tomography (18F-DOPA PET/CT) helps to differentiate focal from diffuse CHI.Objective and hypotheses: To evaluate the feasibility of using 18F-DOPA PET/CT for the diagnosis of focal or diffuse CHI u...

Introduction: Congenital hyperinsulinism (CHI) includes two major histological subtypes; diffuse and focal. Fluorine-18-L dihydroxyphenylalanine positron emission tomography (18F-DOPA PET/CT) has been established as a novel imagining technique to differentiate focal from diffuse CHI. However CT provides only limited soft tissue contrast and exposes the patient to a significant radiation dose. PET/MRI could provide images with an excellent soft tissue contrast, very ...
