Wire localized breast biopsy (WLB) is the most commonly performed procedure for the removal of non-palpable breast cancer. It is associated with patient discomfort and high re-excision rates. Intraoperative ultrasound (IOUS) is an alternative technique that may improve patient experience and have lower re-excision rates.
A retrospective, single surgeon experience with IOUS is compared with WLB. Case matching for variables known to impact re-excision rates is performed. Fisher's exact test was performed for categorical variables, and a T-test for continuous variables.
28 patients underwent IOUS and WLB. Re-excision rates were the same in patients undergoing IOUS and WLB (10.7% vs 0%; p = 0.24). The calculated resection ratio was lower with IOUS than WLB (2.99 vs 3.46; p = 0.37), but did not reach statistical significance.
In selected patients, intra-operative ultrasound can be performed with a favourable re-excision rate, and comparable amounts of tissue compared to wire localized breast biopsy.
经皮导丝定位乳腺活检（WLB）是最常用于切除不可触及乳腺癌的方法。它会导致患者不适和高切检率。术中超声（IOUS）是一种替代技术，它可能会改善患者的体验并降低切检率。
回顾性比较了单外科医生使用 IOUS 和 WLB 的经验。对已知影响切检率的变量进行病例匹配。对于分类变量使用 Fisher 确切检验，对于连续变量使用 T 检验。
28 例患者接受了 IOUS 和 WLB。IOUS 和 WLB 患者的切检率相同（10.7% vs 0%；p=0.24）。IOUS 组的切除比例低于 WLB 组（2.99 比 3.46；p=0.37），但无统计学意义。
在选择的患者中，与经皮导丝定位乳腺活检相比，术中超声可实现有利的切检率和相当数量的组织切除。
