#3682 Endoscopic ultrasound-guided radiofrequency ablation of low-grade insulinomas

Introduction: Insulinomas are rare pancreatic neuroendocrine neoplasms that may cause significant symptoms and substantially reduce quality of life. In resectable patients, the current treatment recommendation is surgery with either enucleation or resection of all or parts of the gland. This treatment may be associated with high morbidity and long convalescence. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a new and minimally invasive treatment for patients with insulinomas.

#17 Diagnostic efficacy of the secretin stimulation test for the Zollinger-Ellison syndrome: an intra-individual comparison using different dosages in patients and controls

Introduction: The diagnosis of Zollinger-Ellison syndrome is suspected in patients with symptoms of gastric acid hypersecretion, i.e., peptic ulcer disease, malabsorption or diarrhea, or with elevated fasting serum gastrin levels. However, symptoms can be masked by the use of proton pump inhibitors and fasting serum gastrin values are not always conclusive. Therefore, the secretin stimulation test is advocated as the principal diagnostic tool to identify the Zollinger-Ellison syndrome.
