Surgical safety and effectiveness of bilateral axillo-breast approach robotic thyroidectomy: a systematic review and meta-analysis

Efficacy and Safety of Robotic Bilateral Axillo-Breast Approach Versus Robotic Gasless Axillary Approach for Thyroidectomy: A Systematic Review and Meta-Analysis

OBJECTIVES

To evaluate the comparative efficacy and safety of robotic thyroidectomy techniques, including the robotic bilateral axillo-breast approach (BABA) and the robotic gasless axillary approach (GAA).

DATA SOURCES

A comprehensive literature search was conducted across 5 major electronic databases (PubMed, Embase, Cochrane Library, Web of Science, and Scopus) to identify relevant studies published until May 2024.

REVIEW METHODS

Analysis was conducted using RevMan 5.4 software with pooled mean and rate ratios calculated with 95% CIs.

RESULTS

A total of 73 studies, comprising 70 eligible for meta-analysis, were included. Compared with robotic GAA, robotic BABA was associated with significantly longer operative time (pooled mean: 64.65 min, 95% CI: 51.77-77.53, P<0.00001), increased hospital stay (pooled mean: 1.24 d, 95% CI: 0.92-1.56, P<0.00001), and higher intraoperative bleeding (pooled mean: 44.90 mL, 95% CI: 26.99-62.81, P<0.00001). While no significant differences were observed in the rates of hypoparathyroidism, recurrent laryngeal nerve palsy, chyle leakage, seroma, hematoma, or infection, the incidence of Horner syndrome was significantly higher in the BABA group (pooled risk ratio: 0.01, 95% CI: 0.00-0.05, P=0.003).

CONCLUSIONS

Robotic BABA was associated with longer operative times, increased hospital stays, and higher intraoperative bleeding compared with Robotic GAA, although both techniques demonstrated comparable safety profiles for most outcomes. The higher incidence of Horner syndrome with BABA should be considered when selecting the optimal surgical approach for thyroidectomy.

Robotic Revolution in Thyroid Surgery: An Umbrella Review of Clinical Outcomes

Objective

This umbrella review aims to evaluate the clinical outcomes of robotic-assisted thyroid surgery compared to traditional endoscopic and open surgical approaches.

Data Sources

We conducted a systematic search of PubMed, EMBASE, and Cochrane Database through August 2024.

Review Methods

We conducted a comprehensive analysis of systematic reviews and meta-analyses that compare robotic-assisted thyroid surgery with endoscopic or open methods. The primary outcomes assessed include surgical efficiency indicators, general postoperative complications, specific complications (nerve and endocrine), postoperative recovery and patient experience, and recurrence and long-term prognosis. The methodological quality of the included reviews was assessed using the AMSTAR2 tool.

Results

Of the 1987 articles retrieved, 21 were eligible. Robotic surgery, though associated with longer operative times, offers distinct advantages in terms of precision. Although robotic surgery shows some variation in central lymph node dissection and an increase in postoperative drainage, its safety is comparable to both open and endoscopic techniques. Additionally, robotic surgery demonstrates superior cosmetic outcomes and shorter hospital stays from multiple approaches, though its high costs remain a significant factor. In terms of recurrence and survival rates, no significant differences were observed between robotic and open surgery.

Conclusion

Robotic surgery choices should balance benefits, costs, and patient needs. As technology and skills improve, efficiency and cost-effectiveness may increase, expanding its clinical role.

Defining competencies in robotic thyroidectomy: development of a model assessing an expert operator's intraoperative performance skills and cognitive strategies

Background

The changing medical education environment emphasizes the need for time efficiency, increasing the demand for competency-based medical education to improve trainees' learning strategies. This study was performed to determine the competencies required for successful performance of robotic thyroidectomy (RT) and to determine the consensus of experts for performance of RT.

Methods

Data were collected through 12 semi-structured interviews with RT experts and 11 field observations. Cognitive task analysis was performed to determine the competencies required for experts to perform RT. A modified Delphi methodology was used to determine how 20 experts rated the importance of each item of RT performance on a Likert 7-point scale. The criteria for the Delphi consensus were set at a Cronbach's α≥0.80 with two survey rounds.

Results

After 11 field observations and 12 semi-structured interviews, 89 items were identified within six modules. These items were grouped into sub-modules according to their theme. The modified Delphi survey, involving 21 experts, reached the consensus standard during the second round (Cronbach's α=0.954), enabling the identification of the 64 most important items within six modules related to RT performance: midline incision to isthmectomy (MID module; n=8), lateral dissection (LAT module; n=7), preservation of inferior parathyroid glands (INF module; n=16), preservation of recurrent laryngeal nerve and dissection of the ligament of Berry (BER module; n=21), dissection of the thyroid upper pole (SUP module; n=10), and specimen removal and closure (END module; n=2).

Conclusions

This mixed-method study combining qualitative and quantitative methodology identified modules of core competencies required to perform RT. These modules can be used as a standard and objective guide to train surgeons to perform RT and evaluate outcomes.
