Objectives:
The aim of this study was to evaluate outcomes of transperitoneal and retroperitoneal approaches in laparoscopic adrenalectomy (LA) for pheochromocytoma.
Methods:
We retrospectively compared the results of transperitoneal LA (TLA) with that of retroperitoneal LA (RLA) in 99 patients with unilateral pheochromocytoma (<6 cm in diameter). Age of patients ranged from 20 to 63 years (42 men and 57 women; 56 in right and 43 in left). The mean operation time, blood loss, mean hospital stay after operation, fluctuation range of blood pressure, blood pressure after operation, complication, mortalities, and recurrences were considered.
Results:
There were significant differences between RLA and TLA in terms of duration of surgery 84 ± 17 minutes versus 117 ± 24 minutes (p < 0.05), intraoperative blood loss 200 ± 22.5 ml versus 340 ± 41.7 ml (p < 0.05), mean hospital stay after operation 4.8 ± 1.6 days versus 7.8 ± 2.2 days (p < 0.05), and complication 12.5% versus 6.7% (p < 0.05). There was no significant difference between RLA and TLA in terms of fluctuation range of blood pressure (p > 0.05) and blood pressure after operation (p > 0.05). There were no mortalities or recurrences of tumors in all patients during follow-up.
Conclusions:
Compared with TLA, RLA is safer, more quick, and effective for patients with unilateral pheochromocytoma (< 6 cm in diameter).
