Laparoscopic Adrenalectomy

Abstract

Purpose We investigated the following issues regarding laparoscopic adrenalectomy: techniques and advantages, indications in adrenal diseases, and the special case of pheochromocytoma. Methods Qualified literature reports were reviewed and integrated with results of our initial experience with laparoscopic adrenalectomy. Results Most authors prefer a transperitoneal approach, but some (including ourselves) use the retroperitoneal approach. Laparoscopic adrenalectomy is as effective and safe as traditional surgery, but the associated morbidity was found to be much lower in laparoscopic series. The need for conversion to open surgery does not exceed 5% of all cases. Practically all adrenal masses can be managed by laparoscopy. The only clinical situations where laparoscopy is not recommended as first choice are large adrenal masses (>6 cm) and gross cortical carcinoma, which are related conditions. Laparoscopy is also indicated in pheochromocytoma. No mortality and an elevated hypertension cure rate (75–100%) have been reported. Hypertension and plasma volume contraction must be normalized prior to surgery. Special attention should be paid to possible severe blood pressure variations during surgery. Partial adrenalectomy has been recently proposed for bilateral and familial pheochromocytoma in order to avoid lifelong mineral corticoid replacement therapy. Conclusions Laparoscopic adrenalectomy currently represents the first surgical choice for adrenal masses. Only large lesions that are suspected to be malignant should not be electively submitted to this procedure. Pheochromocytoma can be safely and effectively treated with laparoscopic surgery; special care for related symptoms is required.
