Surgical Technique and Perioperative Outcomes Following Single-Port Robotic Adrenalectomy: A Single Institutional Experience.

Objective: To describe a single institution's experience with single-port robotic adrenalectomy (SP-RA) and report perioperative outcomes. Materials and Methods: This is a retrospective, single-center study of adult patients who underwent SP-RA between January 2019 and April 2022 by a single surgeon using an IRB-approved institutional database. Patient demographics, perioperative data, surgical pathology, and postoperative outcomes were assessed. Results: Nineteen patients were identified who underwent SP-RA by a single surgeon over the period reviewed. One patient underwent bilateral SP-RA for bilateral adrenal masses, totaling 20 SP-RA procedures performed. Mean operative time was 80.7 ± 22.9 minutes and mean length of stay was 33.1 ± 27.9 hours. Two minor complications (Clavien-Dindo <IIIa) occurred, and one major complication (Clavien-Dindo ≥IIIa) occurred at a mean follow-up of 107.8 ± 159.0 days after surgery. Among 20 surgical specimens, mean mass diameter was 5.2 ± 3.9 cm with one positive margin reported on final pathology (5%). Conclusion: SP-RA provides an effective approach for the surgical management of select adrenal masses with low risk for perioperative complications. Additional studies with increased sample size are needed to validate our findings and to determine the costs associated with performing SP-RA.
