IntroductionLaparoscopic adrenalectomy (LA) is a safe minimally invasive approach for treatment of pheochromocytoma (PHEO). Posterior retroperitoneoscopic adrenalectomy (PRA) is an alternative minimally invasive technique; however, there is a lack of data regarding the appropriateness of this approach in patients with PHEO.MethodsOur endocrine surgery database was queried to identify patients who underwent LA or PRA for PHEO. Patient and tumor characteristics, as well as operative details and postoperative course were compared between the 2 groups.ResultsLA or PRA was attempted in 46 patients with PHEO (23 LA, 23 PRA). There were no differences in age, BMI, or tumor size between these groups. PRA was associated with significantly reduced operative times (99 min vs 145 min, P < .001), estimated blood loss (8.4 cc vs 123.8 cc, P = .02), and postoperative length of stay (1.9 nights vs 3.1 nights, P < .01). There was no significant difference in rates of conversion to an open procedure or perioperative complications between these groups.ConclusionLA and PRA are both safe and effective approaches in patients with PHEO. In our experience, PRA results in decreased operative times, blood loss, and postoperative length of stay compared with LA. PRA has become our preferred approach for patients with PHEO.Copyright © 2011 Mosby, Inc. All rights reserved.
