Abstract
PURPOSE: To explore the laparoscopic technique with the retroperitoneal approach for complex adrenal tumors. PATIENTS AND METHODS: The clinical data of 11 patients with complex adrenal tumors from July 2017 to July 2018 were analyzed retrospectively. Among them, there were 4 males and 7 females, 4 with adrenal myelolipomas, 3 with adrenal pheochromocytomas, 2 with adrenal cysts, 1 with adrenocortical adenoma and 1 with adrenal ganglioneuroma. The average tumor diameter was 6.5 ± 1.2 cm, and the average age of the patients was 48 ± 13 years. RESULTS: All the operations were successfully completed. The average operation time was 95 ± 15 min, the average amount of blood loss was 50 ± 15 mL, and the average postoperative hospital stay was 2.6 ± 1.3 days. No tumor recurrence was found after 1 year of follow-up. CONCLUSION: Retroperitoneal laparoscopic surgery is effective for the treatment of complex adrenal tumors, but it requires good surgical skills. Surgeons skilled in laparoscopic technology can safely carry out retroperitoneal laparoscopic surgery for complex adrenal tumors.
