Perioperative management during laparoscopic resection of large pheochromocytomas: A single-institution retrospective study.

Compared with small-sized pheochromocytomas, laparoscopic resection of medium-sized pheochromocytomas requires vigilant monitoring and resolution of hemodynamic fluctuations. Patients with very large pheochromocytomas are at greater risk of intraoperative bleeding and may benefit from the ensured availability of blood products and intensive postoperative monitoring.
