Retroperitoneal laparoscopic adrenalectomy: clinical experience in 52 procedures.
OBJECTIVE
Laparoscopic adrenalectomy has become an effective option for removal of small adrenal tumors. The aim of this prospective study was to evaluate the retroperitoneal approach with regard to intraoperative complications, morbidity, and length of hospital stay.


METHODS
Between September 1996 and October 1999, we performed 52 laparoscopic adrenalectomies (31 left, 21 right) for benign lesions by a retroperitoneal approach in 44 patients (27 women, 17 men) with a mean age of 46.9 years (range 17 to 74). The average adrenal tumor size was 32 mm (range 10 to 63). All procedures required four trocars and a mean operative time of 135 minutes (range 75 to 240).


RESULTS
There was no mortality, conversion rate to open surgery was 1.9%, and estimated blood loss was 80 mL (range 30 to 200). With a mean follow-up of 16 months, morbidity was 17.2%, which included intraoperative complications (5. 7%) with two vascular injuries, and postoperative complications (11. 5%) with wound infections, deep hematoma, and parietal dehiscence. Average length of hospital stay was 5 days with a mean analgesic consumption of 2 days (range 1 to 5).


CONCLUSIONS
The retroperitoneal approach in laparoscopic adrenalectomy appears to be a minimally invasive and safe therapeutic option that may become the standard for unilateral or bilateral adrenal tumors not larger than 7 cm. However, a learning curve in laparoscopy is indispensable before starting this type of procedure.
