Abstract: Abstract：Object To highlight the effectivity and safety of 3D-laparoscopic surgery to adrenal pheochromocytomas /paragangliomas. Methods 24 cases of adrenal pheochromocytomas and 11 paragangliomas proven pathologically from 2013 to 2015were treated by 3D-laparoscopic surgery. Endocrine secretion examinations , B-US , CT, MRI , 131ＩMIBG ,and octreotide were used to diagnose the diease. Patients took α-receptor blocker for 2-4 weeks preoperatively. 211 patients from 2003 to 2010 by 2D laparoscopic surgery were compared . Results All the operations were completed successfully. There were no major intraoperative complications. Mean tumor diameter in 3D group was (4.12±1.95)cm and (3.97±2.21)cm in 2D group , without significant difference (P>0.05). Mean estimated blood loss in 3D group was (57.8±35.3)ml and (84.6±56.3) ml in 2D group , without significant difference (P>0.05).Mean hospital stay after operation in 3D group was (3.9±1.3) d and (4.9±1.6) d in 2D group without significant difference (P>0.05) . Mean operating time in 3D group was (69±19)min and ( 97±29) min in 2D group, with significant difference (P <0.05).They were followed up for 3-30months. There were no recurrences of tumor .Conclusions 3D-laparoscopic surgery has obvious advantage in spatial location and the sense of depth for adrenal pheochromocytomas /paragangliomas ，which make the operation easier and shortens the operation time obviously.
