#4507 Biliary complications for metastatic patients with neuroendocrine tumours of the pancreatic head and their influence on survival: Is it necessary to change the current management?

Introduction: Neuroendocrine tumours of the pancreatic head (NETPH) can be associated with local complications. At the metastatic stage, surgery of the primary tumour (PT) is not a standard of care. But the biliary complications (BC) due to the untreated NETPH may complicate the management and deteriorate the prognosis.

#4463 Evaluating multi-visceral resection for locally advanced and metastatic pancreatic neuroendocrine tumours (PNETs): Feasibility, safety and complications

Introduction: Pancreatic neuroendocrine tumours (PNETs) are rare but clinically significant neoplasms. Surgery can play a significant role in the multimodal treatment of PNETs. Multi-visceral resection involving organs in the left upper quadrant (LUQ) can be used with curative or cytoreductive intent in selected cases.

#4441 Gastric neuroendocrine neoplasms in younger patients: A retrospective single-centre study

Introduction: Gastric neuroendocrine neoplasms (gNENs) are rare neoplasms arising from stomach enterochromaffin-like (ECL) cells. Type I gNENs are the most common type, typically indolent and arising in the context of chronic atrophic gastritis (CAG). While type I gNENs are generally diagnosed in pts over 50, their occurrence in younger pts raises concern about the onset of CAG-related complications at an earlier age, potentially affecting tumour growth and clinical outcomes. Young-oriented studies on type I gNETs are still lacking in literature.

#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.

#4367 Comparative analysis of post-pancreatic surgical complications in elderly versus younger patients with inactive neuroendocrine pancreatic tumours

Introduction: The management of small, asymptomatic non-functional pancreatic neuroendocrine neoplasms (NF-pNENs) is contentious, with two main approaches: surgical resection and "watch-and-wait." Current guidelines recommend monitoring NF-pNENs under 2 cm based on retrospective data, although recent U.S. studies suggest improved survival with surgery for 1-2 cm NF-pNENs. Some suggest the "watch-and-wait" approach for older patients, though its efficacy is unclear.
