Pectus carinatum (PC) is the second most common deformity of the anterior chest wall, resulting in detrimental effects on body image and quality of life. This study evaluated the safety, effectiveness, and factors associated with the treatment of PC using a sandwiched bar and screw fixation system, first performed in Vietnam at the University Medical Center Ho Chi Minh City in 2016.
This retrospective cohort study was conducted from March 2016 to February 2023 in patients with PC and PC-mixed pectus excavatum (PE) deformities. All patients underwent corrective surgery using the sandwiched bar and screw fixation system. Data were collected on demographic characteristics, operative time, length of hospital stay, Haller Index (HI), and postoperative complications. The effectiveness of the procedure was evaluated based on changes in the HI. Statistical analyses were performed using paired t-tests to compare preoperative and postoperative HI values, and multivariate linear regression was used to identify factors associated with postoperative outcomes.
Of the 39 consecutive patients, 12 (30.8%) had symmetric PC, 10 (25.6%) asymmetric PC, and 17 (43.6%) had PC with an excavatum complex. The mean operative time was 68.1 ± 35.8 min, and the length of stay was 5.3 ± 1.1 days. The preoperative and postoperative Haller index (HI) values were 1.96 ± 0.13 and 2.49 ± 0.14, respectively ( < 0.001). Independent variables correlated to postoperative HI included the asymmetry index absolute value (coefficient () = 0.649, < 0.001) and angle of sternal rotation ( = -0.008, < 0.001). The percentage of patients with good outcomes was 97.4%. No serious procedure-related complications were observed.
Minimally invasive repair using the sandwiched bar and screw fixation system is an effective and safe treatment for PC. Sternal rotation and asymmetry index contribute to its effectiveness by correlating to postoperative HI.
鸡胸是前胸壁第二常见的畸形，会对身体形象和生活质量产生不利影响。本研究评估了2016年在越南胡志明市大学医学中心首次使用夹棒和螺钉固定系统治疗鸡胸的安全性、有效性及相关因素。
本回顾性队列研究于2016年3月至2023年2月对患有鸡胸及鸡胸合并漏斗胸畸形的患者进行。所有患者均采用夹棒和螺钉固定系统进行矫正手术。收集了人口统计学特征、手术时间、住院时间、哈勒指数（HI）和术后并发症的数据。根据HI的变化评估手术效果。采用配对t检验比较术前和术后HI值进行统计分析，并使用多元线性回归确定与术后结果相关的因素。
在39例连续患者中，12例（30.8%）为对称鸡胸，10例（25.6%）为不对称鸡胸，17例（43.6%）为鸡胸合并漏斗胸畸形。平均手术时间为68.1±35.8分钟，住院时间为5.3±1.1天。术前和术后哈勒指数（HI）值分别为1.96±0.13和2.49±0.14（<0.001）。与术后HI相关的独立变量包括不对称指数绝对值（系数（）=0.649，<0.001）和胸骨旋转角度（=-0.008，<0.001）。良好结局患者的比例为97.4%。未观察到严重的手术相关并发症。
使用夹棒和螺钉固定系统的微创修复是治疗鸡胸的一种有效且安全的方法。胸骨旋转和不对称指数通过与术后HI相关而有助于其有效性。
