Abstract OBJECTIVES The OrtenBodyOne scanner is a radiation-free, 3-dimensional imaging system recently developed for evaluation of the severity of pectus excavatum (PE). The goal of this study was to evaluate the utility of this new imaging system compared with that of computed tomography (CT) for the evaluation of the severity of PE. METHODS Patients treated for PE from April 2015 to January 2017 with available CT and OrtenBodyOne data were included. Correlations between indexes calculated from CT and from OrtenBodyOne were determined by applying the non-parametric Spearman correlation procedure with a Bonferroni correction to adjust for multiple comparisons. RESULTS Forty men (90.9%) and 4 women (9.1%), 20 with symmetrical (45.5%) and 24 with asymmetrical PE (54.5%), were included. The median age was 16.1 years (range 4.3–63.5 years). The following measures and indexes acquired using OrtenBodyOne and CT were significantly correlated: pectus depth (r = 0.84; P = 0.002), anthropometric index (r = 0.81; P = 0.002) and asymmetry index (r = 0.67; P = 0.002). The correlation between the CT Haller index and the external Haller index was only significant for symmetrical PE (r = 0.57; P = 0.008). CONCLUSIONS The OrtenBodyOne imaging system can be used to evaluate the severity of symmetrical PE using the external Haller index. Asymmetry and anthropometric indexes are more reliable for the evaluation of asymmetrical PE. Measures can be repeated throughout treatment while avoiding unnecessary irradiation.

The Impact

Background. There is high risk in the correction surgery of pectus excavatum with scoliosis because of the lack of the correction mechanism of pectus excavatum with scoliosis. This study performed a comprehensive analysis about the impact that pectus excavatum had on scoliosis and elaborated its biomechanical mechanism in pectus excavatum patients with scoliosis. Methods. 37 pectus excavatum patients were selected. According to age, Haller index of pectus excavatum, offset coefficient, vertical position, sternal torsion angle, and asymmetric index, 37 patients were, respectively, divided into 2 compared groups. The result was statistically calculated. Results. The scoliosis incidence and severity did not correlate with Haller index, offset coefficient, vertical position, sternal torsion angle, and asymmetric index of pectus excavatum, and there was no statistical significance between the two compared groups. Conclusions. The incidence and severity of scoliosis in PE patients with scoliosis have nothing to do with the geometric parameters of pectus excavatum but correlate with age. The scoliosis will aggravate with the increase of age. The heart may provide an asymmetric horizontal force to push the spines to the right. The mechanism of how the biomechanical factors exert influences on spines needs to be further investigated to keep the spine stable.

Abstract Introduction The Nuss procedure is the most common and preferred operative correction of pectus excavatum. Surgeon preference and patient factors can result in variations in Nuss procedure technique. We hypothesize that certain techniques are associated with increased risk of complications. Materials and Methods We performed a single-center retrospective review of Nuss operations from 2016 to 2020. Variations in intraoperative techniques included sternal elevator (SE) use, number of bars placed, and usage of bilateral stabilizing sutures. Patient demographics, intraoperative data, and postoperative outcomes were reported as median with interquartile ranges or percentages. Statistical significance (p < 0.05) was determined with Wilcoxon's rank-sum and chi-square tests. Multivariate analysis was performed to control for introduction of intercostal nerve cryoablation and surgeon volume, and reported as odds ratio with 95% confidence interval. Results Two hundred and sixty-five patients were identified. Patients repaired with two bars were older with a larger Haller index (HI). Patient demographics were not significantly different for SE or stabilizing suture use. Placement of two bars was associated with significantly increased risk of readmission. Similarly, SE use was associated with increased risk of pleural effusion and readmission. Finally, the use of bilateral stabilizing sutures resulted in less frequent slipped bars without statistical significance. Conclusion Older patients with a larger HI were more likely to need two bars placed to repair pectus excavatum. Placement of multiple bars and SE use are associated with significantly higher odds of certain complications.

Introduction: Pectus excavatum (PEX) is a depression of the sternum which can physically constrict the heart and cause abnormal ECGs. The Nuss operation is a minimally invasive technique for PEX repair. Hypothesis: As right (RA) and left atria (LA) are compressed in PEX, axes of P, QRS, and T waves are abnormal and the Nuss operation normalizes them. We also took the Haller index (HI) into to account. Methods: 17 PEX patients (14 male, 12±6 years) underwent CT and ECG before and after the Nuss operation. Results: All Nuss operations were successful, and HI was significantly improved from 5.62±2.29 to 3.29±0.65 (P=0.0002). There were no significant differences before and after surgery for electrical axes of P waves (46±20 vs 65±55, P=0.20), and QRS waves (75±33 vs 76±23, P=0.72), but T waves were greater thereafter (22±27 vs 40±19, P=0.001). Correlation coefficients (CC) between the degree of axes of P, QRS and T waves, and HI before operation were -0.23, -0.06, and 0.11, respectively. These values after operation were -0.25, -0.06, and 0.19, respectively. As HI is an indirect indicator of heart compression, we evaluated the degree of RA and LA compression qualitatively as none, mild, and moderate/more. Of 17 patients, 5 had moderate/more compression of RA and/or LA by PEX (group 1); the remaining 12 did not show compression (group 2). Only P wave values were significantly smaller in group 1 than 2 before surgery, but these differences disappeared after surgery. In both groups, degree of axes of T waves was significantly greater after the operation. Conclusion: In patients with PEX, axes of T waves after the Nuss operation became significant greater than before the operation in patients with moderate or more compression of RA and/or LA by PEX. For P waves, this was smaller before the operation in those with compression but this was improved by the Nuss operation. P and T wave axes but not QRS could be therefore non-invasive indicators of Nuss operation success in addition to gross PEX appearance.
