Bronchiectasis is a significant cause of morbidity. Surgical resection is a treatment option, but its main outcomes regarding quality of life (QOL) and physiologic consequences have not been addressed previously, to our knowledge. We aimed to evaluate the effect of surgical procedures on QOL, exercise capacity, and lung function in patients with bronchiectasis in whom medical treatment was unsuccessful.
Patients with noncystic fibrosis in whom medical treatment was unsuccessful and who were candidates for lung resection were enrolled in a prospective study. The main measurements before lung resection and 9 months afterward were QOL according to the Short Form 36 Health Survey and World Health Organization Quality of Life Questionnaires, lung function test results, and the results of maximal cardiopulmonary exercise testing on a cycle ergometer.
Of 61 patients who were evaluated, 53 (50.9% male, age 41.3 ± 12.9 years) underwent surgical resection (83% lobectomies), and 44 completed the 9-month follow-up. At baseline, they had low QOL scores, mild obstruction, and diminished exercise capacity. After resection, 2 patients died and adverse events occurred in 24.5%. QOL scores improved remarkably at the 9-month measurements, achieving values considered normal for the general population in most dimensions. Functionally, resection caused mild reduction of lung volume; nevertheless, exercise capacity was not decreased. In fact, 52% of the patients improved their exercise performance. Multiple linear regression analysis showed that low QOL before resection was an important predictor of QOL improvement after resection (p = 0.0001).
Lung resection promotes a significant improvement in the QOL of patients with noncystic fibrosis bronchiectasis without compromising their exercise capacity.
支气管扩张症是一种重要的发病原因。手术切除是一种治疗选择,但据我们所知,其主要的生活质量(QOL)和生理后果尚未得到解决。我们旨在评估手术对治疗无效的支气管扩张症患者的 QOL、运动能力和肺功能的影响。
我们招募了患有非囊性纤维化且药物治疗无效且适合肺切除术的患者进行前瞻性研究。肺切除术前和术后 9 个月的主要测量指标包括:根据短型 36 健康调查和世界卫生组织生活质量问卷评估的 QOL,肺功能测试结果以及在循环测功仪上进行的最大心肺运动测试的结果。
在接受评估的 61 例患者中,有 53 例(50.9%为男性,年龄 41.3±12.9 岁)接受了手术切除(83%为肺叶切除术),其中 44 例完成了 9 个月的随访。基线时,他们的 QOL 评分较低,存在轻度阻塞和运动能力下降。切除后,有 2 例患者死亡,24.5%的患者发生了不良事件。9 个月时的 QOL 评分显著改善,大多数维度达到了一般人群的正常值。在功能上,切除导致肺容积轻度减少;然而,运动能力并未下降。实际上,有 52%的患者提高了运动能力。多元线性回归分析表明,切除前的低 QOL 是切除后 QOL 改善的重要预测指标(p = 0.0001)。
肺切除可显著改善非囊性纤维化支气管扩张症患者的 QOL,而不会降低其运动能力。
