The present best practice for performing esophageal reconstruction using colon tissue was investigated in this review. The left colon has advantages in that it has less variation in blood supply and a smaller diameter than the right colon; however, the rate of graft necrosis is higher for the left colon. Additional microvascular anastomosis, which is unnecessary in most cases, may be able to resolve these issues. The colon graft should be reconstructed in an isoperistaltic fashion whenever possible in order to prevent regurgitation and improve food transit. The posterior mediastinum has the advantage of being the shortest route, but it also has the major disadvantage that graft necrosis can be severe or fatal if it occurs. In palliative or advanced cases, a retrosternal or subcutaneous route is preferred, because the posterior mediastinum is a tumor bed. However, in these cases partial excision of the manubrium and the left clavicula should be considered to release compression of the graft at the thoracic inlet. Consequently, the selection of the colon graft should be flexible and be based on the inspection of blood supply and the length needed, and thereafter microvessel anastomosis should be added in cases where graft ischemia might occur.
本研究旨在探讨目前使用结肠组织进行食管重建的最佳实践。左结肠具有以下优点:其血供变异较小,直径小于右结肠;但左结肠的移植物坏死率更高。在大多数情况下,无需进行额外的微血管吻合术,这可能有助于解决这些问题。只要可能,结肠移植物应采用等蠕动方式重建,以防止反流和改善食物通过。后纵隔的优点是最短的路径,但它也有一个主要的缺点,即如果发生移植物坏死,可能会很严重甚至致命。在姑息性或晚期病例中,胸骨后或皮下途径是首选,因为后纵隔是肿瘤床。然而,在这些情况下,应考虑部分切除胸骨柄和左锁骨,以释放对胸廓入口处移植物的压迫。因此,结肠移植物的选择应具有灵活性,并应根据血供和所需长度进行检查,此后,如果可能发生移植物缺血,应添加微血管吻合术。
