However, the grade of restriction differs in each patient. It is currently unknown, how disparities between actual and predicted recipient total lung capacity (TLC), impact changes in lung function parameters and long-term outcomes following lung transplantation (LTx). </p><p class="ql-block">在间质性肺疾病(ILD)患者中,随着肺部的慢性萎缩,膈肌通常会上升。然而,每位患者的限制程度各不相同。目前尚不清楚,实际与预测的受体总肺容量(TLC)之间的差异如何影响肺移植(LTx)后肺功能参数的变化和长期结果。</p><p class="ql-block">Methods 方法</p><p class="ql-block">This retrospective study included 170 LTx for the patients with ILD performed in a European high-volume LTx center between 09/2011 and 12/2022. The preoperative median ratio of recipient actual to predicted (a/p) TLC was 0.55. Patients were stratified into two groups: low a/p TLC ratio group, corresponding to a more restricted chest cavity (&lt; 0.55: n = 85), and high a/p TLC ratio group, corresponding to a more preserved chest cavity (≥ 0.55: n = 85). Perioperative and long-term outcomes, including lung function and overall survival, were analyzed.</p><p class="ql-block">这项回顾性研究囊括了在2011年9月至2022年12月期间,在欧洲大型LTx中心进行的170例ILD患者LTx。术前受体实际与预测总肺容量(a/p)TLC的中值比率为0.55。患者被分为两组:低a/p TLC比率组,对应于更为受限的胸腔(&lt; 0.55:n = 85),以及高a/p TLC比率组,对应于保留更好的胸腔(≥ 0.55:n = 85)。分析了围手术期和长期结果,包括肺功能和总生存率。</p><p class="ql-block">Results 结果</p><p class="ql-block">Between the two groups, tracheostomy and re-intubation rates, length of mechanical ventilation, ICU-stay and hospital-stay were not significantly different. Although lung function measurements obtained early after LTx were better in the high a/p TLC ratio group, no significant differences were observed in the long term. 5-year overall survival was not significantly different between the two groups. </p><p class="ql-block">两组之间的气管切开和再次插管率、机械通气时间、ICU住院时间和住院时间没有显著差异。尽管LTx后早期获得的肺功能测量值在高a/p TLC比率组中更好,但长期来看没有显著差异。两组的5年总生存率没有显著差异。</p><p class="ql-block">Conclusions 结论</p><p class="ql-block">Although LTx for ILD patients with a restricted chest is considered technically more challenging, the perioperative course is similar to ILD patients with a preserved chest. In addition, no significant differences were observed between both groups in long-term lung function and overall survival, suggesting an improvement in chest wall compliance.</p><p class="ql-block">尽管对胸腔受限的ILD患者进行LTx在技术上更具挑战性,但围手术期过程与胸腔保留的ILD患者相似。此外,两组在长期肺功能和总生存率方面没有显著差异,这表明胸壁顺应性有所改善。</p><p class="ql-block">AI全文解析</p><p class="ql-block">这篇文章研究了 限制性胸腔(Restricted Chest) 对于间质性肺疾病(Interstitial Lung Disease, ILD)患者在肺移植后长期肺功能的影响。以下是文章的重点总结:</p><p class="ql-block">研究背景</p><p class="ql-block">1. 间质性肺疾病特点:</p><p class="ql-block">• ILD 是一种限制性肺病,会导致肺容量减少和膈肌升高。</p><p class="ql-block">• 胸腔限制性变化因患者而异,可能影响肺移植的手术难度和术后效果。</p><p class="ql-block">2. 研究目的:</p><p class="ql-block">• 探讨术前胸腔实际/预测总肺容量比值(actual/predicted TLC ratio, a/p TLC ratio)对肺移植术后肺功能和长期生存的影响。</p><p class="ql-block">• 验证限制性胸腔是否会导致术后不良结果。</p><p class="ql-block">研究方法</p><p class="ql-block">• 研究设计:</p><p class="ql-block">• 单中心回顾性研究,纳入 2011 年至 2022 年间进行肺移植的 170 名 ILD 患者。</p><p class="ql-block">• 根据术前 a/p TLC 比值分为两组:</p><p class="ql-block">• 低 a/p TLC 比值组 (&lt;0.55,表示胸腔更受限)。</p><p class="ql-block">• 高 a/p TLC 比值组 (≥0.55,表示胸腔保存较好)。</p><p class="ql-block">• 观察指标:</p><p class="ql-block">• 围手术期结果:如气管切开、再插管、机械通气时长、ICU 住院天数等。</p><p class="ql-block">• 长期结果:肺功能(FEV1 和 TLC 比值)、5 年总体生存率。</p><p class="ql-block">主要结果</p><p class="ql-block">1. 围手术期结果:</p><p class="ql-block">• 两组在气管切开率、再插管率、机械通气时间、ICU 和住院时间上没有显著差异。</p><p class="ql-block">• 低 a/p TLC 比值组的移植第二侧肺耗时略长,但差异不显著。</p><p class="ql-block">2. 肺功能变化:</p><p class="ql-block">• 术后早期(1-2 个月):</p><p class="ql-block">• 高 a/p TLC 比值组的肺功能(FEV1 和 TLC)显著优于低 a/p TLC 比值组。</p><p class="ql-block">• 术后长期(12 个月及以后):</p><p class="ql-block">• 两组间的肺功能无显著差异,表明低 a/p TLC 组的胸壁顺应性逐步改善。</p><p class="ql-block">3. 总体生存率:</p><p class="ql-block">• 两组的 5 年生存率相似(低组 71.5%,高组 71.2%),差异无统计学意义。</p><p class="ql-block">研究结论</p><p class="ql-block">• 技术挑战:</p><p class="ql-block">• ILD 患者中的严重限制性胸腔虽增加了手术的技术难度,但围手术期结果与保存较好的胸腔患者相当。</p><p class="ql-block">• 长期恢复:</p><p class="ql-block">• 胸壁顺应性在术后逐渐改善,即使在限制性胸腔患者中也无显著不良影响。</p><p class="ql-block">• 临床意义:</p><p class="ql-block">• 限制性胸腔不应被视为肺移植的绝对禁忌症。</p><p class="ql-block">• 未来需进一步研究胸壁重塑机制和优化术后管理。</p><p class="ql-block">局限性</p><p class="ql-block">1. 单中心研究,结果的普适性有限。</p><p class="ql-block">2. 回顾性设计存在潜在偏倚,样本量较小。</p><p class="ql-block">3. 未能全面评估不同移植中心的技术差异。</p><p class="ql-block">这项研究表明,即使在胸腔受限的 ILD 患者中,肺移植也能够取得与胸腔保存较好的患者相似的长期结果,提供了更多治疗信心。</p><p class="ql-block">喜欢SCI天天读的理由</p><p class="ql-block">陪您一起学习SCI医学论文</p><p class="ql-block">每天5分钟,让自己的英语牛逼起来</p><p class="ql-block">特殊福利让您惊喜连连</p><p class="ql-block">复制链接或点击原文链接,即可下载SCI原文</p><p class="ql-block">W248N03</p><p class="ql-block">链接: https://pan.baidu.com/s/1oPa5RX_u7L_ChRAhX3NMNQ?pwd=jvyy </p><p class="ql-block"><br></p><p class="ql-block">​</p>
