Respiratory tract fistulas (or fistulae) are abnormal communications between the respiratory system and the digestive tract or the adjacent organs. The origin can be congenital or, more frequently, iatrogenic and the clinical presentation is heterogeneous. Respiratory tract fistulas can lead to severely reduced health-related quality of life and short survival. Therapy mainly relies on endoscopic surgical interventions but patients often require prolonged hospitalization and may develop complications. Therefore, more conservative regenerative medicine approaches, mainly based on lipotransfer, have also been investigated. Adipose tissue can be delivered either as unprocessed tissue, or after enzymatic treatment to derive the cellular stromal vascular fraction. In the current narrative review, we provide an overview of the main tissue/cell-based clinical studies for the management of various types of respiratory tract fistulas or injuries. Clinical experience is limited, as most of the studies were performed on a small number of patients. Albeit a conclusive proof of efficacy cannot be drawn, the reviewed studies suggest that grafting of adipose tissue-derived material may represent a minimally invasive and conservative treatment option, alternative to more aggressive surgical procedures. Knowledge on safety and tolerability acquired in prior studies can lead to the design of future, larger trials that may exploit innovative procedures for tissue processing to further improve the clinical outcome.

再生医学方法治疗呼吸道瘘

呼吸道瘘是呼吸系统与消化道或邻近器官之间的异常通讯。起源可能是先天性的,或更常见的是医源性的,临床表现是异质的。呼吸道瘘管可导致与健康相关的生活质量严重下降和生存期短。治疗主要依靠内窥镜手术干预,但患者通常需要长期住院,并可能出现并发症。因此,还研究了主要基于脂质转移的更保守的再生医学方法。脂肪组织可以未处理的组织形式进行输送,也可以经过酶处理后传递到细胞基质血管中。在目前的叙述性评论中,我们概述了基于主要组织/细胞的临床研究,以管理各种类型的呼吸道瘘管或损伤。临床经验有限,因为大多数研究是针对少数患者进行的。尽管无法得出确切的疗效证明,但已审查的研究表明,脂肪组织来源的材料的移植可能代表了一种微创和保守的治疗选择,替代了更具侵略性的外科手术方法。先前研究中获得的有关安全性和耐受性的知识可能会导致设计未来的大型试验,这些试验可能会利用创新的组织加工程序来进一步改善临床结果。因为大多数研究都是针对少数患者进行的。尽管无法得出确切的疗效证明,但已审查的研究表明,脂肪组织来源的材料的移植可能代表了一种微创和保守的治疗选择,替代了更具侵略性的外科手术方法。先前研究中获得的有关安全性和耐受性的知识可能会导致设计未来的大型试验,这些试验可能会利用创新的组织加工程序来进一步改善临床结果。因为大多数研究都是针对少数患者进行的。尽管无法得出确切的疗效证明,但已审查的研究表明,脂肪组织来源的材料的移植可能代表了一种微创和保守的治疗选择,替代了更具侵略性的外科手术方法。先前研究中获得的有关安全性和耐受性的知识可能会导致设计未来的大型试验,这些试验可能会利用创新的组织加工程序来进一步改善临床结果。
