Transperitoneal, transmesocolic approach for laparoscopic excision of an extra-adrenal pheochromocytoma

Laparoscopic surgery is an established treatment modality for adrenal disease, especially pheochromocytomas. We describe the successful excision of an extra-adrenal pheochromocytoma using a novel transperitoneal, transmesocolic approach. The tumor was located inferior to the left renal hilum in the para-aortic region and was found bulging through the descending mesocolon at laparoscopy. The tumor was removed without mobilization of the descending colon.
