Laparoscopic adrenalectomy in pheochromocytomas

BACKGROUND: The aim of this study was to evaluate 17 patients undergoing laparoscopic adrenalectomy for the treatment of pheochromocytoma by transperitoneal anterior approach. METHODS: Seventeen patients underwent laparoscopic adrenalectomy for pheochromocytoma between January 1994 and May 2002. Ten females (58.8%) and 7 males (41.2%) were operated on; 14 patients (82.3%) had sporadic pheochromocytoma and 3 (17.7%) were familiar cases. Mean age was 42 yr (range 25-72 yr). All patients were treated pre-operatively with alpha-blockers. Seven patients (41.2%) underwent right adrenalectomy; 9 (52.9%) underwent left adrenalectomy and 1 (5.9%) bilateral adrenalectomy. RESULTS: No conversion to open surgery occurred and no mortality was observed. The right-side adrenalectomy required a mean operative time of 86 min (range 45-120), the left-side procedure a mean operative time of 116 min (range 80-140) and the bilateral one 219 min. In two patients (11.8%), a laparoscopic cholecystectomy and ovariectomy, respectively, were performed without changing the position of the patient on the operating table. Only 1 patient (5.9%) presented significant intraoperative hypertension, and arrhythmia resolved by medical therapy. No other intraoperative and post-operative complications were reported. Mean hospital stay was 3 days (range 2-8 days). At mean follow-up of 48 months (range 6-96 months), regression of symptoms and control of blood pressure were obtained without additional treatment in all patients. No recurrences were reported. CONCLUSION: In our experience, adrenal pheochromocytoma can be treated safely and effectively by laparoscopic transperitoneal anterior approach.
