En Bloc Resection with Major Blood Vessel Reconstruction for Locally Invasive Retroperitoneal Paragangliomas: A 15-Year Experience with Literature Review

摘要

Retroperitoneal paragangliomas (PGs) are a rare subgroup of neuroendocrine tumors that are commonly located alongside the abdominal aorta. Complete tumor resection is thought to be restricted in patients with major blood vessel involvement. However, no study has specifically focused on aggressive surgical treatment in such patients. We evaluated the value of en bloc resection with major blood vessel reconstruction for locally invasive retroperitoneal PGs.
