RESUMO
Background: The Nuss procedure is currently the mainstream of pectus excavatum (PE) surgery; however, it is considered to be more difficult for asymmetric cases than for symmetric ones. Sternocostal elevation (SCE), which was performed at our hospital, is a surgical method that determines the extent of resection of the costal cartilage while comparing the left and right balance during surgery; thus, it is highly useful for correcting rib cage with strong asymmetry. Methods: Of the 256 patients who underwent SCE at our hospital between July 2014 and July 2022, 58 (22.7%) with asymmetric PE were retrospectively examined. However, patients with advanced scoliosis having a Cobb angle of 25° or higher were excluded; therefore, 51 (19.9%) patients were analyzed. Two indices and other measurements were evaluated to determine the success of correction for asymmetry using computed tomography (CT). Results: The difference between the left and right thoraxes, the Haller index, and the sternal torsion angle significantly improved. Furthermore, we herein set a new numerical index as an indicator of asymmetry improvement and to be used for a more standard thorax morphology; the difference between the left and right thoraxes/the average of the left and right thoraxes. That new index also significantly improved. Conclusions: SCE is considered a highly useful surgical method for asymmetric PE.
RESUMO
BACKGROUND: Fungal infections are rarely reported as a complication of bronchial thermoplasty (BT) in patients without immunosuppressive comorbidity. CASE PRESENTATION: A 19-year-old woman college student was admitted to our hospital owing to uncontrolled severe asthma despite using the maximum dose of steroid inhalation. She experienced asthmatic attacks more frequently while cheerleading, which is an extracurricular activity. She received BT because she wanted to continue cheerleading. After the second BT session, she developed more sputum and cough. During the third session, white secretion and saccular bronchodilation appeared in the left lower bronchus. Aspergillus fumigatus was detected in the culture of the bronchial lavage sample, and saccular bronchodilation in the affected bronchus was observed on computed tomography (CT). Five months after the start of oral itraconazole, her subjective symptoms as well as her CT findings improved. Her asthma condition improved enough for the patient to continue cheerleading without exacerbation. CONCLUSIONS: It is necessary to consider the possibility of respiratory tract infections including fungal infections after BT. Detailed observations of the entire bronchus and sample collection for microbial culture are highly recommended.
