Laparoscopic adrenalectomy: a report of the first experience in iran.

Purpose: To report the first experience in laparoscopic adrenalectomy and to study its efficacy and safety in the treatment of different adrenal diseases. Materials and Methods: From March 1997 to July 2001, 11 patients underwent laparoscopic adrenalectomy through transperitoneal approach, five of whom were males and 6 were females. Their mean age was 35.5 (range 28 to52) years. Lesion was located on the left side in 6 patients and on the right side in 5. All necessary evaluations were done preoperatively including CT scan, MRI, MIBG scan, and endocrine tests such as ACTH, cortisol, mineralocorticoid, 17-hydroxyprogesterone, and urinary VMA. Three (5, 10, and 12 mm) trocars were used in left laparoscopic adrenalectomy and three or four (12, 10, 5, and 5 mm) trocars were applied in right laparoscopic adrenalectomy. All the patients were followed up for three months with physical examination and paraclinical tests. Results: Mean operative time (including anesthesia and surgery) was 205±65.95 (range 130 to 310) minutes. No significant difference was seen between the operative time in the left side and the right side adrenalectomy (p=0.5). Mean hospitalization was 5.54±3.4 (range 3 to15) days. Mean size of mass was 5.45±1.7 (range 2 to 8) cm. Blood transfusion was performed in 2 patients and open surgery was conducted for one because of extensive adhesions. No mortality was reported. During a 3-month follow-up, hormonal tests and blood pressure were normal for all the patients, with no medical treatment being required. Conclusion: Our study demonstrated that transperitoneal laparoscopic adrenalectomy is an effective and safe approach in the treatment of adrenal masses with the least morbidity.
