Abstract
Background: Minimally invasive repair of pectus excavatum (MIRPE) improves clinical outcomes and chest wall morphology. However, asymmetry in patients with pectus excavatum (PE) remains as an important issue, even after surgery. Here, we evaluated the benefit of double-bar technique in achieving a symmetric chest wall.
Methods: This retrospective study included 79 patients with PE who underwent MIRPE between 2017 and 2021. The patients were divided into the double- or non-double-bar groups. Asymmetric degree (AD) and sternal rotation angle (SRA) were used to assess the severity of asymmetry based on computed tomography (CT) images. The primary outcome was the change in radiologic parameters. Secondary outcomes were clinical results, including hospital stay, pain scores, and complication rates. Subgroup analysis of patients with preoperative asymmetric PE was performed.
Results: Patients in the double-bar group (n=23) were younger than those in the non-double-bar group (n=56). Additionally, the double-bar group exhibited lower pain scores and shorter hospital stay. Based on radiological assessments, the double-bar group demonstrated a greater decrease in AD without compromising improvement in the Haller index (HI). The benefit of the double-bar technique was more obvious among patients with asymmetry with a preoperative AD >5%, resulting in a significant reduction in AD. In this subgroup, a better correction of sternal rotation was observed.
Conclusions: The double-bar technique may be a promising option for correcting asymmetry in patients with PE. Simplified AD and SRA radiologic assessments can be used to evaluate improvements in chest wall configuration.
