Abstract: Background: Due to variations in location and size, laparoscopic surgery for paraaortic or paracaval neurogenic tumors is challenging. We evaluated the surgical outcomes, as well as surgical tips and tricks. Methods: Between 2000 and 2015, 25 procedures were performed in 24 patients. One patient underwent second surgery due to the recurrence of paraganglioma. Data were collected on the tumor diameter, tumor location, perioperative outcomes, pathology, and last known disease status. Regarding the operative procedures, we reviewed the operative charts or videos to identify surgical tips and tricks. Results: The median tumor diameter was 5.0 cm (range, 1.5-10). The tumor location was suprahilar in 10, hilar in 6, and infrahilar in 9. Regarding the approach, a transperitoneal approach was selected in 24 cases and retroperitoneal approach in 1. The median operative time and blood loss were 208 minutes (range, 73-513) and 10 mL (range, 0-1,020), respectively. No patient required blood transfusion or conversion to open surgery. Pathological examination revealed paraganglioma in 12, ganglioneuroma in 7, and schwannoma in 6. At the last follow-up, 23 patients were free of disease, while one patient developed metastatic multiple recurrence of paraganglioma 54 months after the second laparoscopic surgery. A review of the surgical records revealed several tips and tricks, including taping the vena cava/ renal vein (n=2) being helpful for detaching a retrocaval tumor from these great vessels, or rotating the kidney to provide a favorable operative view of tumors behind the renal hilum (n=2). In recent cases, 3D-CT was helpful for preoperative planning. Conclusion: Laparoscopic resection of paraaortic or paracaval neurogenic tumors is feasible in experienced hands. Surgeons should be familiar with detaching maneuvers around great vessels and the mobilization of adjacent organs. Careful preoperative planning is mandatory.
