#4523 Preoperative evaluation of tumour border using radiomics and its surgical guidance in pancreatic neuroendocrine tumours

Introduction: Pancreatic neuroendocrine tumours are a heterogeneous group of tumours originating from peptidergic neurons and neuroendocrine cells with variable survival outcomes. Surgical resection is the mainstay of treatment. However, there is an ambiguous insight into the real need to execute the standard surgery in small pancreatic neuroendocrine tumours. The tumour border is a powerful determinant of survival prognosis in many tumours and is often used as a safety guarantee for parenchyma-sparing resections. However, there are no studies evaluating tumour border with or without preoperative imaging in pNETs.

#4430 Long-term prognosis of parenchyma-sparing vs. oncologic resections for distal pancreatic non-functional neuroendocrine tumours ≤ 3cm: A real-world data study (CSPAC-NEN-5)

Introduction: Studies show that parenchyma-sparing resections (PSR) for small, non-functional pancreatic neuroendocrine tumours (NF-pNETs) provide long-term outcomes similar to oncologic resections (OR). However, these studies have not fully considered location-based differences in surgical approach and lymphatic drainage.

#3123 Arterial calcium-stimulated venous sampling to reveal insulinoma in case of pancreatic multiple neuroendocrine neoplasms

Introduction: Insulinoma is a functioning pancreatic neuroendocrine tumor (pNET) that produces insulin and causes clinical symptoms of severe hypoglycemia. The arterial calcium stimulation with hepatic venous sampling (ASVS) can localize the insulin-producing tumor and help to avoid the excessive volume of surgery in case of multiple pancreatic neuroendocrine tumors.

#2931 One-Stage Middle-Preserving Pancreatectomy: Indications and Outcomes

Introduction: Parenchyma-sparing surgical techniques are used in pancreatic surgery to preserve organ function. Middle-preserving pancreatectomy (MPP) may be an alternative to total pancreatectomy (TP) in benign/borderline disease that does not affect pancreatic body.
