Background: Posterior retroperitoneoscopic adrenalectomy (PRA) is an excellent surgical option for adrenal gland removal. The operation requires that surgeons learn a new approach with few similarities to anterior adrenalectomy. This study reports a large series of PRAs incorporated into surgical care using a team-model approach.
Study design: The prospective endocrine surgery database was queried to identify patients who underwent PRA during a recent 4-year period. Demographic, operative, and pathologic data were recorded. The authors' initial experiences with PRA (group 1) are compared with our contemporary experience (group 2).
Results: One hundred and eighteen PRAs were successfully performed (100 unilateral and 9 bilateral). Indications were pheochromocytoma in 21 patients, Cushing's syndrome or Cushing's disease in 22 patients, aldosteronoma in 22 patients, virilizing tumor in 3 patients, isolated metastasis in 28 patients, and nonfunctional mass in 19 patients. Forty-eight percent of patients had undergone earlier abdominal surgery. Forty-eight percent were obese (body mass index [calculated as kg/m(2)] ≥30). No significant differences were found in operative time (110 versus 118 minutes, p = 0.30), tumor size (2.59 versus 2.85 cm, p = 0.44), or body mass index (29.63 versus 29.93, p = 0.82) between groups 1 and 2. Both complications (15.9% versus 7.7%, p = 0.29) and conversion rates (9.5% versus 1.9%, p = 0.19) were lower in group 2, although this was not statistically significant.
Conclusions: PRA is a technique safely performed for a variety of adrenal lesions, is ideal for patients who have undergone earlier abdominal surgery, and is feasible in obese patients. Proficiency can be obtained during a short period, leading to low conversion and complication rates. This technique should be incorporated into the armamentarium of the endocrine surgeon. A team approach to learning new surgical techniques is effective.
