Endoscopic ultrasound-guided ethanol ablation for the management of a symptomatic pancreatic insulinoma.

Introduction: pancreatic insulinoma is a sporadic, usually benign, frequently solitary tumor that is smaller than 20 mm. When it is functioning, patients present with symptoms of hypoglycemia secondary to insulin hypersecretion. The diagnosis is clinical, with biochemical and radiological confirmation. Surgery is the management of choice, although endoscopic ultrasound-guided ablation is currently being developed.
Material and Methods: we present a prospective case series of pancreatic insulinoma patients with symptoms of severe hypoglycemia, who were treated with endoscopic ultrasound-guided ethanol ablation as an alternative to surgical management.
Results: technical and clinical success was achieved in all cases and there were no complications associated with the procedure.
Conclusion: the treatment of symptomatic insulinoma by endoscopic ultrasound-guided ethanol ablation could be a safe and effective alternative to surgical management in non-surgical patients or those who refuse surgery.
