Abstract
Objective: To investigate the feasibility and safety of interventional embolization combined with robotic surgery for adrenal pheochromocytoma. Methods: A retrospective analysis was conducted on clinical data from three patients with adrenal pheochromocytoma who underwent interventional embolization combined with robotic surgery at Tianjin First Central Hospital from June 2022 to March 2024. All patients underwent preoperative adrenal artery embolization followed by robot-assisted laparoscopic adrenalectomy. Clinical data including operative time, intraoperative blood loss, postoperative drainage tube duration, postoperative hospital stay, pathological findings, and follow-up results were collected. Focusing on its impact on maintaining perioperative (particularly intraoperative) hemodynamic stability, and to evaluate its effect on reducing intraoperative blood loss. Results: Among the three patients, one was male and two were female, with ages of 50, 76, and 46 years, respectively. Pheochromocytomas were located on the left side in two cases and on the right side in one case. The maximum tumor diameters were 6.0 cm, 6.2 cm, and 5.8 cm, respectively. All three procedures were successful without conversion to open surgery. The operative times were 117, 181, and 127 minutes, respectively. Intraoperative blood loss was 100 ml, 50 ml, and 30 ml, respectively, with no intraoperative blood transfusion required. Postoperative drainage tube durations were 4, 4, and 3 days, respectively. Postoperative hospital stays were 7, 6, and 6 days, respectively. One patient experienced a hypertensive episode after embolization, while the other two experienced hypertensive episodes during embolization, all of which were controlled with medication. During robotic surgery, all three patients maintained stable blood pressure, and no other surgery-related complications were observed. Complete resection of the adrenal tumors was achieved in all cases. During robotic surgery, a significant reduction in adrenal blood supply was noted. Postoperatively, two patients developed hypotension, which stabilized after norepinephrine infusion. Follow-up ranged from 10 to 30 months, with a median follow-up of 22 months. All patients maintained stable blood pressure levels, with no tumor recurrence or complications observed. Conclusions: Preoperative interventional embolization combined with robot-assisted surgery for pheochromocytoma is safe and feasible. It contributes to maintaining intraoperative hemodynamic stability while reducing tumor blood supply, thereby decreasing perioperative blood loss and potentially lowering surgical difficulty.
