First Experience of Single Port Robotic Areolar (SPRA) Thyroidectomy and Modified Radical Neck Dissection (MRND)

摘要

Background and Objectives: After introducing the single-port robotic surgical system (da-Vinci SP), thyroid surgeries using da-Vinci SP are becoming more popular. Although many methods have been designed for thyroidectomy using the da-Vinci SP, there are very few reports on methods that can perform not only thyroidectomy but also lateral cervical lymph node dissection. In this study, we want to report the first clinical experience with SPRA-MRND (Single Port Robotic Areolar-Modified Radical Neck dissection), using right breast access. Materials and Methods: From April 2024 to January 2025, a total of 24 robotic MRNDs were performed, of which 11 were SPRA-MRNDs. The remaining 13 were performed using conventional BABA surgery. The two data sets were compared through retrospective medical record analysis. Results: There were no significant differences regarding patient characteristics, pathologic variables and oncologic outcomes between the two groups. However, SPRA group showed significantly shorter operation time (182.1 ± 27.5 vs. 213.1 ± 31.5 min, p = 0.017), higher immediate postoperative calcium level (calcium: 8.7 ± 0.5 vs. 8.0 ± 0.8 mg/dL, p = 0.014) and lower drainage amount (98.1 ± 33.2 vs. 146.4 ± 43.2 mL, p = 0.005). Conclusions: Our initial experience has shown that SPRA-MRND is performed safely. We propose SPRA-MRND as a good method for minimally invasive robotic surgery.
