用游离结肠段插补或移植重建颈段食管有一些缺点,如:结肠从皮下经过时外形难看;若从胸骨后和纵隔通过,结肠因血管梗塞坏死时可以致命;移植时需做较复杂的颈部血管吻合。作者们提出一种新方法,用10只猴进行了实验。具体方法为经上腹正中切口,将左结肠血管和边缘血管与横、降结肠分离开后行双重结扎,结扎血管与肠壁间的所有小分支直至升结肠的近远端处,然后再从肠系膜上把左结肠血管、边缘血管向下分离到升结肠的近端作为血管蒂。切除所有失去血运的横、降结肠,再把一段带长血管蒂的结肠切下。从胸骨前钝性分离出一皮下隧道到颈部。
Interfering with the free colon segment or transplanting the cervical esophagus has some drawbacks, such as: the shape of the colon as it passes from the skin; if passed from the back of the sternum and the mediastinum, the colon can be fatal due to necrosis of the vessel; transplantation requires more complicated Cervical anastomosis. The authors propose a new method to experiment with 10 monkeys. The specific method for the median abdominal incision, the left colon and peripheral blood vessels and transverse and descending colon separated after double ligation, ligation of blood vessels and intestinal wall between all small branches up to the proximal and distal ascending colon, and then from On the mesentery, the left colonic vessels and the marginal vessels are separated downward to the proximal end of the ascending colon as the pedicle. Cut off all the blood loss of the transverse, descending colon, and then cut a long pedicle of the colon. Blunt pre-sphincter isolated a subcutaneous tunnel to the neck.
