ABSTRACT
PURPOSE: Posterior retroperitoneoscopic adrenalectomy (PRA) for small adrenal tumors has recently been in the spotlight due to its several benefits. Compelling advantages for endoscopic surgeons include direct, safe, and fast approach to the adrenal gland without trespass to the intraperitoneal organ. This study reports our initial experiences of PRA for the management of adrenal tumors. METHODS: From December 2009 to August 2011, 63 patients underwent PRA for the management of adrenal tumor. Among these patients, laparoscopic adrenalectomy and robotic adrenalectomy were performed in 54 and nine patients, respectively. We retrospectively reviewed records of all surgical outcomes. RESULTS: Of the 54 patients, 22 were male and 32 were female, and mean age was 51.7±14.0 years. Mean body mass index was 24.6±3.6 kg/m² and mean dimension of the tumors was 2.66±1.36 cm. Six patients were diagnosed with Cushing's disease, 22 patients with primary aldosteronism, seven patients with pheochromocytoma, one patient with metastatic adrenal gland cancer, and 18 patients with nonfunctioning adrenal tumors. Mean operative time was 88.5±27.1 min, mean blood loss was 17.4±37.4 ml, and mean duration to first oral intake was 0.83±0.4 days. Mean number of postoperative analgesics used was 2.28±2.54, and mean postoperative hospital stay was 2.85±1.43 days. There was no open conversion during the operation and no post-operative complication. CONCLUSION: PRA is a safe and fast procedure. In experienced hands, PRA represents one of the ideal approaching methods in the adrenal gland surgery.

PURPOSE: A retroperitoneoscopic adrenalectomy is theoretically the ideal procedure for an adrenalectomy. However, it is not popular due to its technical difficulty. Herein, we report our experience with retroperitoneoscopic adrenalectomies and describe the difficulties encountered during the operations. METHODS: From November 1996 to October 1999, a total of 41 retroperitoneoscopic adrenalectomies were performed. Forty (40) patients had a unilateral adrenal tumor (size: 1?? cm): 21 aldosteronomas, 12 Cushing adenomas, 3 neurogenic tumors, 2 nonfunctioning adenomas, 1 vascular cyst, and 1 angiomyolipoma of the kidney. One (1) had bilateral hyperplasia. The operations were carried out in prone position in all cases with 3 trochars. RESULTS: Thirty five (35) operations were completed endoscopically. Five were converted to open procedures, and one was converted to a transperitoneal laparoscopic approach. The causes of conversion were 1 severe subcutaneous emphysema, 2 technical difficulties, 1 bleeding, 1 partial nephrectomy, and 1 missing tumor. The average operating time for the complete endoscopic adrenalectomies was 183 minutes in the first 14 cases and 142 minutes in the next 21 cases. There was no operative morbidity or mortality. The average hospital stay was 4.3 days in the first 14 cases and 2.8 days in the next 21 cases. CONCLUSION: A retroperitoneoscopic adrenalectomy is a less invasive procedure than any other adrenalectomy procedure, and its only disadvantage is technical difficulty. However, the technical difficulty can be overcome with increasing experience.
