Abstract

Purpose: Predicting perioperative complications in high-risk elderly patients with lung cancer has become increasingly important as the population ages. This study investigated the relationship between preoperative diaphragmatic thickness (DT) and perioperative complications.

Methods: We enrolled 101 patients ≥ 75 years old who had undergone radical resection for primary lung cancer between 2013 and 2018. Bilateral DT was measured on axial and coronal computed tomography, and the mean DT (MDT) was calculated based on these measurements. Outcomes were assessed based on postoperative complications, defined as Clavien-Dindo classification ≥ 2.

Results: The MDT was 3.51 ± 1.00 mm. Thirteen patients who experienced postoperative respiratory complications had a significantly lower MDT than a higher MDT (p = 0.0390). Multivariate logistic regression analyses revealed that an MDT ≤ 3.63 mm was an independent factor associated with postoperative complications (odds ratio, 5.559).

Conclusions: Patients with a low MDT are at an increased risk of postoperative complications. Therefore, these patients require careful perioperative management.

老年非小细胞肺癌患者膈膜厚度与术后并发症的关系

目的：随着人口老龄化，预测老年高危肺癌患者围手术期并发症变得越来越重要。本研究探讨术前膈肌厚度（DT）与围手术期并发症的关系。方法：我们招募了101例≥75岁的患者，他们在2013年至2018年期间接受了原发性肺癌根治术。在轴位和冠状位ct上测量双侧DT，并根据这些测量计算平均DT （MDT）。根据术后并发症评估结果，定义为Clavien-Dindo分级≥2。结果：MDT为3.51±1.00 mm。13例出现术后呼吸系统并发症的患者MDT明显低于MDT较高的患者（p = 0.0390）。多因素logistic回归分析显示MDT≤3.63 mm是与术后并发症相关的独立因素（优势比为5.559）。结论：低MDT患者术后并发症的风险增加。因此，这些患者需要仔细的围手术期管理。

期刊介绍： Surgery Today is the official journal of the Japan Surgical Society. The main purpose of the journal is to provide a place for the publication of high-quality papers documenting recent advances and new developments in all fields of surgery, both clinical and experimental. The journal welcomes original papers, review articles, and short communications, as well as short technical reports("How to do it"). The "How to do it" section will includes short articles on methods or techniques recommended for practical surgery. Papers submitted to the journal are reviewed by an international editorial board. Field of interest: All fields of surgery.
