AB008. Treatment of retroperitoneoscopic adrenalectomy for pheochromocytoma

Background: To evaluate the efficacy and safety of retroperitoneoscopic adrenalectomy for the treatment of pheochromocytoma.

Methods: The clinical data of 39 cases of adrenal pheochromocytoma were analyzed retrospectively. All of the cases underwent retroperitoneoscopic adrenalectomies for pheochromocytoma, including 16 cases of male and 23 cases of female. The ages of the patients were from 18 to 73 years and the average age was 43.3 years. Twenty tumors were on the 1eft side, and 19 were on the right. The mean tumor size was 4.45±0.97 cm in diameter (range, 3.0 to 8.0 cm).

Results: 37 operations were completed successfully. The mean operating time was 45.3±3.27 min (range, 30.0 to 110.0 min). Estimated blood loss was 66.7±14.45 mL. Mean hospital stay after operation was 5 days. Two cases were transferred to traditional open operation, because of the adhesion with the tail of the pancreas and the inferior vena cava. Thirty-eight cases were no transfusion during or after operation.

Conclusions: Before perform retroperitoneoscopic adrenalectomy, we need to investigate the CT carefully. As long as preoperative preparations are adequate and intraoperative manipulations are careful, adrenalectomy for pheochromocytoma could be safe in the minimally invasive retroperitoneoscopic way.
