Comparison of Perioperative Outcomes Using the da Vinci S, Si, X, and Xi Robotic Platforms for BABA Robotic Thyroidectomy

Abstract

Background and Objectives: Robotic thyroidectomy via the bilateral axillo-breast approach (BABA), first introduced in Korea in 2008, has become a standard method of thyroid removal worldwide. The introduction of robotic surgical systems has enabled more patients to benefit from BABA robotic thyroidectomy, with good postoperative and excellent cosmetic results. To date, no studies have compared the benefits of the four currently available da Vinci robotic systems (S, Si, X, and Xi) for BABA robotic thyroidectomy. To determine the da Vinci model most suitable for BABA robotic thyroidectomy, the present study compared the perioperative outcomes in patients who underwent BABA robotic thyroidectomy using the four da Vinci models. Materials and Methods: This retrospective study evaluated outcomes in patients (n = 750) who underwent BABA robotic thyroidectomy using the four da Vinci systems from 2013 to 2019. The clinicopathologic data, including operation time, were compared. Substudy A compared the da Vinci models S and Si from 2013 to 2017, and substudy B compared models Si, X, and Xi from 2018 to 2019. Results: Substudy A, comparing the da Vinci S and Si systems, found no statistically significant differences between the two groups, whereas substudy B found that operation time was shorter in patients who underwent BABA robotic thyroidectomy with the da Vinci Xi system than with the Si and X systems. Conclusions: The da Vinci model Xi system can benefit patients undergoing BABA robotic thyroidectomy by shortening the operation time.

Comparison of surgical outcomes of da Vinci surgical systems X and Xi: A single‐center study

“…During robotic thyroidectomy surgery, the Xi system required a shorter operative time than the X system. 9 As the robotic arms of the X system are fixed to the patient-side cart, access to the patient's head is impaired. However, Bergmann et al 10 reported no serious complications associated with either system during rectal surgery.…”

Comparison of Surgical Outcomes of da Vinci Surgical Systems X and Xi: A Single-center Study

“…The X and Xi systems have been compared for other types of surgery. During robotic thyroidectomy surgery, the Xi system required a shorter operative time than the X system [9]. As the robotic arms of the X system are xed to the patient-side cart, access to the patient's head is impaired.…”

Using the da Vinci X® - System for Esophageal Surgery

“…Compared to the da Vinci® Xi system which is considered the high-end model, the more affordable da Vinci® X system has some limitations. 31 The robotic arms are directly mounted to the patient cart whereas the arms of the Xi systems are mounted to an overhead boom offering more flexibility. Based upon our experience, the potential disadvantages of the da Vinci X are not clinically relevant.…”
