INTRODUCTION Breast conserving surgery of impalpable breast lesions requires safe and effective localisation techniques. Wire localisation has traditionally been used, but has limitations. Newer techniques are now being introduced to mitigate this. The iBRA-NET group aims to robustly evaluate these new techniques in well-designed prospective studies. We report the first phase of this evaluation, a survey to establish current practice and service provision of breast localisation techniques in the UK. METHODS A national practice questionnaire was designed using 'SurveyMonkey®' and was circulated to UK breast surgeons via the Association of Breast Surgery and the Mammary Fold. The questionnaire was live from 6th October 2018 to 6th April 2019. Only one response per unit was requested to reflect the unit's practice. RESULTS Complete responses were received from 98 breast units across the UK. Wires were the mostly commonly used localisation technique (n = 82) with fewer units using Magseed® (n = 9), Radioguided Occult Lesion Localisation (n = 5) and Radioiodine Seed Localisation (n = 2). There was significant variation in practice and logistics involved. Frequent delays and theatre overruns were reported in 39 and 16 units, respectively. The median satisfaction score of the current technique was 7 out of 10. The main perceived limitation of existing localisation methods was logistics affecting theatre scheduling and the main barrier to introducing a new technique was cost. CONCLUSION Wires are currently the most commonly used localisation technique but are associated with significant logistical issues. Newer techniques may offer a better solution but will need robust evaluation before they are adopted to ensure safety and efficacy.

无法触及的乳房病变定位，后勤挑战：英国 iBRA-NET 国家实践问卷的结果。

介绍 无法触及的乳房病变的保乳手术需要安全有效的定位技术。传统上使用线定位，但有局限性。现在正在引入更新的技术来缓解这种情况。iBRA-NET 小组旨在通过精心设计的前瞻性研究有力地评估这些新技术。我们报告了此评估的第一阶段，这是一项旨在建立英国乳房定位技术的当前实践和服务提供的调查。方法 使用“SurveyMonkey®”设计了一份全国实践问卷，并通过乳腺外科协会和乳腺褶皱协会分发给英国的乳腺外科医生。问卷于 2018 年 10 月 6 日至 2019 年 4 月 6 日进行。每个单元仅要求一份回复以反映该单元的实践。结果 全英国 98 个乳房单位收到了完整的答复。导线是最常用的定位技术 (n = 82)，使用 Magseed® (n = 9)、Radioguided Occult Lesion Localization (n = 5) 和 Radioiodine Seed Localization (n = 2) 的单位较少。所涉及的实践和后勤工作存在重大差异。分别报告了 39 个和 16 个单元的频繁延误和剧院超支。当前技术的满意度中位数为 7 分（满分 10 分）。现有本地化方法的主要感知限制是影响剧院调度的物流，而引入新技术的主要障碍是成本。结论 电线是目前最常用的定位技术，但与重大的后勤问题相关。
