Safety and Efficacy of EUS-RFA in Pancreatic Insulinoma (EUSRFAINSU)

May 8, 2026 updated by: Per Hedenström, Sahlgrenska University Hospital

Transcutaneous and EUS-guided radiofrequency ablation are both modern modalities to apply in the managemnet of various malignancies.

In the current study the investigators aim to study the technical feasibility, patient safety and clinical efficacy of EUS-RFA for the treatment of pancreatic insulinoma.

Intervention / Treatment

Detailed Description

Patients (P): Alla patients referred to Sahlgrenska University Hospital for the diagnostic work-up and management of a suspected pancreatic insulinoma.

Intervention (I): EUS-RFA

Control group (C): Patients with insulinoma treated with conventional surgery during the time frame 2018-2025 (historic controls).

Outcome (O):

  • Technical feasibility
  • Patient safety
  • Clinical efficacy (follow-up with biochemistry and imaging at 3, 6, 12, and 24 months post-EUS-RFA).
