Introduction: Organ preserving surgery(OPS) has been accepted for pancreatic neuroendocrine neoplasm(PNEN), particularly in a small and low malignant tumors.
Aim(s): The aim of this study was to analyze the surgical outcome after these OPS in our institute, especially focusing on the lymph-node metastasis and post operative locoregional recurrence.
Materials and methods: 48 consecutive patients with PNEN underwent operation between 2003 and 2015. Patients were retrospectively classified into one of two groups: Organ Preserving group (OPG) and Standard operation group (SOG). We have applied OPS based on size criteria with tumor size less than 1.5cm in non-functional PNEN and less than 2cm in insulinoma with no evident bulky lymph-node swelling on preoperative imaging.
