背景:胸导管(TD)和乳糜池(CC)的地形和形态特征表现出高度的变异性。材料与方法:PubMed,Scopus,Embase,WebofScience,科克伦图书馆,和GoogleScholar进行了搜索,以确定所有研究,其中包括有关TD和CC的形态计量学和地形特征的信息。结果:TD终止的最常见位置是左静脉角,合并患病率为45.29%(95%CI:25.51-65.81%)。此外,TD最常见的是单血管终止(合并患病率=78.41%;95%CI:70.91-85.09%).然而,它分为两个或两个以上的终止分支在大约四分之一的情况下。CC的合并患病率为55.49%(95%CI:26.79-82.53%)。结论:我们的荟萃分析揭示了TD和CC解剖结构的显着变异性,特别是关于TD终止模式。尽管单船终止占主导地位,近四分之一的案件表现出分支,突出了TD解剖结构的复杂性。这些发现证明了详细的解剖学知识对于外科医生的重要性,以最大程度地减少头部和颈部意外受伤的风险。还有胸外科手术.我们的研究提供了可以提高手术安全性和疗效的重要见解,最终改善患者预后。
Background: The thoracic duct (TD) and the cisterna chyli (CC) exhibit a high degree of variability in their topographical and morphometric properties. Materials and Methods: PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar were searched to identify all studies that included information regarding the morphometric and topographical characteristics of the TD and CC. Results: The most frequent location of the TD termination was the left venous angle, with a pooled prevalence of 45.29% (95% CI: 25.51-65.81%). Moreover, the TD terminated most commonly as a single vessel (pooled prevalence = 78.41%; 95% CI: 70.91-85.09%). However, it divides into two or more terminating branches in approximately a quarter of the cases. The pooled prevalence of the CC was found to be 55.49% (95% CI: 26.79-82.53%). Conclusions: Our meta-analysis reveals significant variability in the anatomy of the TD and CC, particularly regarding TD termination patterns. Despite the predominance of single-vessel terminations, almost a quarter of cases exhibit branching, highlighting the complexity of the anatomy of the TD. These findings demonstrate the importance of detailed anatomical knowledge for surgeons to minimize the risk of accidental injury during head and neck, as well as thoracic surgeries. Our study provides essential insights that can enhance surgical safety and efficacy, ultimately improving patient outcomes.
