UNLABELLED
Prepectoral breast reconstruction is increasingly popular. This study compares complications between 2 subpectoral and 1 prepectoral breast reconstruction technique.
METHODS
Between 2008 and 2015, 294 two-staged expander breast reconstructions in 213 patients were performed with 1 of 3 surgical techniques: (1) Prepectoral, (2) subpectoral with acellular dermal matrix (ADM) sling ("Classic"), or (3) subpectoral/subserratus expander placement without ADM ("No ADM"). Demographics, comorbidities, radiation therapy, and chemotherapy were assessed for correlation with Clavien IIIb score outcomes. Follow-up was a minimum of 6 months.
RESULTS
Surgical cohorts (n = 165 Prepectoral; n = 77 Classic; n = 52 No ADM) had comparable demographics except Classic had more cardiac disease ( = 0.03), No ADM had higher body mass index (BMI) ( = 0.01), and the Prepectoral group had more nipple-sparing mastectomies ( < 0.001). Univariate analysis showed higher expander complications with BMI ≥ 40 ( = 0.05), stage 4 breast cancer ( = 0.01), and contralateral prophylactic mastectomy ( = 0.1), whereas implant complications were associated with prior history of radiation ( < 0.01). There was more skin necrosis ( = 0.05) and overall expander complications ( = 0.01) in the Classic cohort, whereas the No ADM group trended toward the lowest expander complications among the 3. Multivariate analysis showed no difference in overall expander complication rates between the 3 groups matching demographics, mastectomy surgery, risks, and surgical technique.
CONCLUSIONS
Prepectoral and subpectoral Classic and No ADM breast reconstructions demonstrated comparable grade IIIb Clavien score complications. BMI > 40, stage 4 cancer, and contralateral prophylactic mastectomy were associated with adverse expander outcomes and a prior history of radiation therapy adversely impacted implant outcomes. Ninety-day follow-up for expander and implant complications may be a better National Surgical Quality Improvement Program measure.

胸肌前乳房重建越来越受欢迎。本研究比较了两种胸肌下和一种胸肌前乳房重建技术的并发症。
方法
2008年至2015年期间，对213例患者进行了294例两阶段扩张器乳房重建，采用三种手术技术之一：（1）胸肌前，（2）胸肌下带脱细胞真皮基质（ADM）吊带（“经典法”），或（3）胸肌下/锯肌下放置扩张器且无ADM（“无ADM法”）。评估人口统计学、合并症、放疗和化疗与Clavien IIIb评分结果的相关性。随访至少6个月。
结果
手术队列（胸肌前组n = 165；经典法组n = 77；无ADM法组n = 52）的人口统计学特征具有可比性，只是经典法组心脏病更多（P = 0.03），无ADM法组体重指数（BMI）更高（P = 0.01），且胸肌前组保乳手术更多（P < 0.001）。单因素分析显示，BMI≥40（P = 0.05）、IV期乳腺癌（P = 0.01）和对侧预防性乳房切除术（P = 0.1）时扩张器并发症更高，而植入物并发症与既往放疗史相关（P < 0.01）。经典法队列中皮肤坏死（P = 0.05）和总体扩张器并发症（P = 0.01）更多，而无ADM法组在三组中扩张器并发症趋向于最低。多因素分析显示，在匹配人口统计学、乳房切除术、风险和手术技术的情况下，三组之间总体扩张器并发症发生率无差异。
结论
胸肌前、胸肌下经典法和无ADM法乳房重建的Clavien IIIb评分并发症相当。BMI>40、IV期癌症和对侧预防性乳房切除术与扩张器不良结局相关，既往放疗史对植入物结局有不利影响。对扩张器和植入物并发症进行90天随访可能是更好的国家外科质量改进计划指标。
