Purpose: To compare outcomes of robotic adrenalectomy with conventional laparoscopic adrenalectomy.
Materials and Methods: This retrospective study included 63 patients who underwent robotic or laparoscopic adrenalectomy between March 2005 and April 2016, with all operations performed using a transperitoneal approach. Outcomes were compared in the 29 patients who underwent robotic adrenalectomy and the 34 who underwent conventional laparoscopic adrenalectomy.
Results: Mean age (53.1±12.2 years vs. 51.4±15.1 years, p=0.631) and body mass index (25.9±3.8 kg/m2 vs. 25.2±3.5 kg/m2, p=0.461) were similar in the robotic and laparoscopic groups. A significant percentage of patients in the robotic group had undergone prior abdominal surgery (38% vs. 12%, p=0.015). Mean tumor sizes (3.0±1.5 cm vs. 3.7±2.7 cm, p=0.134) and the percentage of incidentalomas (75.9% vs. 73.5%, p=0.354) were similar in the robotic and laparoscopic groups. There were no statistical significance between-group differences in tumor size, operative time, estimated blood loss, perioperative hemoglobin change, length of hospital stay, and complication rates. Pathologic diagnosis showed that pheochromocytoma (21% vs. 3%) and metastatic tumor (24% vs. 6%) were more frequent in the robotic than in the laparoscopic group (p=0.019). Subgroup analysis of patients with low tumor volume (≤6.8 cm3) showed that operation time was significantly shorter in the robotic than in the laparoscopic group (p=0.045).
Conclusions : Robotic adrenalectomy is feasible, with outcomes comparable to those of laparoscopic adrenalectomy.
