Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aims of our study were to define perioperative HI during laparoscopic adrenalectomy for pheochromocytoma, assess the incidence of perioperative HI, and identify predictive factors of perioperative HI in our group of patients.

Laparoscopic adrenalectomy

Preoperative staging in all cases consisted of computed tomography or/and magnetic resonance imaging. Prior to surgery, a routine panel of laboratory tests was carried out. The catecholamines metabolites (metanephrine, normetanephrine, and methoxytyramine) were measured from 24-hour urine collection. All patients were preoperatively treated with phenoxybenzamine or alternative doxazosin.Additionally, beta-blockers in case of coexisting tachycardia were given. In the morning of the operation, preinduction blood pressure was measured. Pneumoperitoneum was achieved by insufflating CO2 gas to an intraperitoneal pressure of 12 mmHg. The operative method in our department was laparoscopic transperitoneal lateral total adrenalectomy. Intraoperatively SBP and diastolic blood pressure (DBP) were measured and recorded every 10 minutes. To treat hypertensive and hypotensive episodes, intravenous doses of urapidil, ephedrine, nitrates, MgSO4, norepinephrine, or ß-blockers were administered.
