#4418 Endoscopic ultrasound-guided radiofrequency ablation is a safe and efficient treatment of symptomatic insulinomas – A single centre experience of 14 patients

Introduction: The vast majority of insulinomas are benign and less than 20 mm. Surgery is considered as standard treatment, but complications are significant. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) represents a novel and minimally invasive approach.

#4382 Sensitivity of endoscopic ultrasound in detecting small gastrointestinal neuroendocrine tumours

Introduction: Small gastrointestinal neuroendocrine tumours (GI-NETs) are often difficult to detect using conventional imaging modalities, leading to delayed diagnosis and suboptimal treatment outcomes. Endoscopic ultrasound (EUS) has emerged as a promising tool for the early detection and precise localisation of these tumours. However, its sensitivity in identifying small lesions remains to be thoroughly evaluated.

#4377 Characteristics of endoscopic ultrasonography in patients with gastrointestinal and pancreatic neuroendocrine tumours

Introduction: Neuroendocrine tumours are most commonly found in the gastrointestinal tract. With the development of endoscopic ultrasound, the incidence of GEP-NENs has increased year by year.

#4350 Cytoendoscopy for determining the depth of invasion and metastasis of rectal neuroendocrine tumours

Introduction: Rectal neuroendocrine tumours (rNETs) are relatively common submucosal tumours, but even low-grade rNETs can metastasise. The significance of endocytology (EC) in the clinical evaluation of rNETs has not been reported.

#4118 Adverse events after endoscopic ultrasound-guided fine-needle aspiration and fine-needle biopsy in pancreatic neuroendocrine tumors: A systematic review

Introduction: Pathological analysis of pancreatic neuroendocrine tumors (pNET) is essential for predicting tumor behaviour and patient management. Although endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the established practice for retrieving tissue, fine-needle biopsy (EUS-FNB) offers possibilities for additional analyses including tumor grading. This systematic review provides a comprehensive evaluation of EUS-FNA and EUS-FNB-related adverse events in pNET.
