Abstract

Objective: To report the outcomes of transperitoneal robotic adrenalectomy (RA) procedures in five initial cases performed at two institutions.
Methods: Between March 2012 and November 2014, five patients underwent RA. A transperitoneal approach was taken by using the da Vinci-S four-arm surgical robot. Outcomes were assessed retrospectively.
Results: Mean patient age was 42.6±5.1 (range: 34-47) years. Mean body mass index was 30.5±4.5 (range: 23.2-35.2) kg/m². Median tumour size detected on radiological imaging was 3.1±1.7 (range: 1.2-6.0) cm. Mean operation time was 129.0±12.4 (range: 120-150) minutes and median estimated blood loss was 100.0±119.3 (range: 50-350) ml. No intraoperative or perioperative complications occurred according to the modified Clavien complication scale. Median duration of hospital stay was 2.0±1.7 (range: 2-6) days. The fourth robotic arm was used in two patients. Histopathology results demonstrated: metastasis of renal cell carcinoma occurred in 1 case, adrenal cortical adenoma in 2 cases, pheochromocytoma in 1 case, and hyperplasia in 1 case. After a median follow-up of 17.0±15.0 (range: 3-40) months, no local recurrence was detected.
Conclusion: RA is a safe minimally invasive surgical approach that has excellent surgical and oncological outcomes in the treatment of adrenal masses <7 cm in size.
