<abstract xmlns="http://www.w3.org/1999/xhtml"> Background: Laparoscopic adrenalectomy (LA) is the preferred approach to adrenal gland tumors.Objective: To evaluate the perioperative and functional outcomes of transperitoneal LA.Methods: We retrospectively reviewed data of all consecutive patients who underwent transperitoneal LA at our institution between April 2000 and December 2011.Results: Two hundred two patients with mean age of 46 years were included in the study. There were 109 left, 89 right, and 4 bilateral tumors. Preoperative diagnosis included 126 aldosterone-producing adenomas (APA), 33 patients with Cushing syndrome, 19 pheochromocytomas, 20 nonfunctional tumors, and 4 adrenal metastases. Mean tumor size was 3.3 cm (range 0.4-22 cm). Mean operative time was 109 min and estimated blood loss 90 mL for unilateral adrenalectomy; and 195 min and 300 mL for bilateral adrenalectomy. Four patients with pheochromocytoma required transfusion and 2 required conversion to an open approach. Seven intraoperative complications and 18 30-day postoperative complications occurred. These included 5 major complications (Clavien-Dindo grade 3-5). Ninety-seven percent of APA patients had normal serum potassium levels after surgery. Among the patients with functioning endocrine tumors, complete resolution rate from secondary hypertension was significantly higher in the pheochromocytoma group compared with those with APA or Cushing syndrome (82% vs. 48% vs. 68% respectively, p = 0.02). Mean follow up was 35.2 months.Conclusion: LA is the treatment of choice for most adrenal gland tumors with excellent outcomes and low complication rates. There was a high chance for complete resolution of secondary hypertension after surgery for pheochromocytoma.</abstract>
