Adrenalectomy by Retroperitoneal Laparoendoscopic Single Site Surgery

BACKGROUND: Laparoscopic adrenalectomy is the current standard for treatment of benign adrenal disease. To reduce the invasiveness of surgery, new techniques have been recently proposed, such as mini-laparoscopy, natural orifice transluminal endoscopic surgery, and laparoendoscopic single site surgery (LESS). Herein, we describe one case of adrenalectomy by retroperitoneal LESS using conventional laparoscopic instruments and ports. CASE REPORT: A 52-year-old female patient with an incidental finding of a 3-cm mass in the left adrenal was referred to us. Preoperative blood concentrations of catecholamines, aldosterone, and cortisol, and urinary excretion of vanilmandelic acid were normal. She underwent an adrenalectomy by retroperitoneal LESS using conventional instruments and ports. Operative time and estimated blood loss were 82 minutes and <50cc, respectively. She was discharged 12 hours after surgery. No intra- or postoperative complications occurred. Pathological analysis of the specimen identified an adrenal cortical adenoma. CONCLUSION: Adrenalectomy by retroperitoneal LESS using conventional laparoscopic instruments is feasible. Further studies must be performed to evaluate safety, indications and benefits of this approach.
