Laparoscopic adrenal surgery in a Brazilian center.
OBJECTIVE
The laparoscopic approach to the adrenal gland was first reported in 1992. Since then, many publications about this issue have come from Europe, Japan, and North America. We reviewed our 7-year experience with laparoscopic adrenal surgery. This is the first large series presented from Latin America.


METHODS
Laparoscopic adrenalectomy was carried out in 61 female and 33 male patients between January 1994 and February 2001. Their ages ranged from 1 to 72 (42.8 +/- 16.4 years) years. Ten patients (10.6%) were 20 years or younger, 10 (10.6%) had unilateral tumors >4 cm, 22 (23.4%) had a Body Mass Index >/= 30, and 10 (10.6%) had had previous open upper abdominal surgery. The size of the lesion ranged from 1 to 9 cm (2.9 +/- 4 cm). Ninety-seven operations were performed, of which 91 were unilateral and 6 were bilateral, adding up to 103 adrenalectomies. Among the 97 procedures, the lateral transperitoneal approach was employed in 94 cases, whereas a lateral retroperitoneal approach enabled 3 adrenalectomies.


RESULTS
Unilateral procedures lasted 117 +/- 43.7 minutes (range 45-250 minutes); bilateral procedures lasted 186 +/- 91.6 minutes (range 100-345 minutes). Five operations (5.1%) were converted to open surgery. Twenty patients (21.3%) suffered complications, 8 (8.5%) being intraoperative and 12 (12.8%) postoperative. Six cases (6.4%) were considered major complications. No deaths occurred. The blood transfusion rate was 4.2%. The hospital stay averaged 6.1 +/- 15.3 days (range 1-140 days). The follow-up period was 17 +/- 12.6 months (range 1-60 months).


CONCLUSIONS
Laparoscopic adrenalectomy is feasible and has excellent results in properly selected patients.
