Value of three-dimensional image reconstruction in robotic operation of massive pheochromocytoma and paraganglioma(Report of 11 cases)

Objective:To discuss the value of three-dimensional image reconstruction in robotic operation of pheochromocytoma/paraganglioma(PHEO/PGL).Methods:From July 2019 to January 2020,the clinical data of 11 patients with PHEO/PGL were retrospectively analyzed.This study included 5 male patients and 6 female patients and the median age was 44 years old(21 to 68 years old).The median value of maximum diameter of tumor was 7.1 cm(ranged 6.2 to 10.2 cm);with 8 cases on adrenal and 3 cases on other retroperitoneal space.All patients underwent four-phase enhanced CT scanning preoperatively.The two-dimensional CT images were collected and reconstructed into a three-dimensional images model through the VitaWorks system.With the help of these 3 D images,the size and location of the tumor,as well as the relationship between tumor and vessels and peripheral organs were observed directly,so that surgeons can locate tumor and plan the operation.Results:After three-dimensional reconstruction,the 3 D image clearly showed the location of tumor and its relationship with surrounding vessels and organs.All patients underwent robot assisted laparoscopic surgery without intra-operative conversion to open surgery.Conclusion:Three-dimensional image construction is valuable for surgery of massive PHEO/PGL and provides an objective basis for decision of surgeon to acquire better perioperative results.
