食管缺损(包括因食管癌切除后的缺损,或因化学性灼伤后造成的颈段、胸段、或颈胸段食管狭窄或闭锁)的修复,至今仍然是一个比较复杂而难度较高的外科治疗问题。过去应用将胃带蒂上徙,空肠或结肠上徙,或应用皮管修复等方法均有一定的缺点,易造成远端肠段坏死,导致手术失败。近年来,由于显微外科技术的发展,已有可能通过肠系膜血管吻合而进行空肠的游离移植,或将部分空肠带蒂,远段空肠进行小血管吻合术式来供应新的血循环,以修复颈段或颈胸段的食管 Esophageal defects, including those due to resection of esophageal cancer, or cervical, thoracic, or cervical esophageal stenosis or atresia following chemical burns, are still a relatively complex and difficult surgical procedure Treatment problems. In the past the application of the stomach to pedicle tremor, jejunum or colon migration, or the application of skin repair and other methods have certain shortcomings, easy to cause necrosis of distal bowel, leading to surgical failure. In recent years, due to the development of microsurgical techniques, it has been possible to perform free transplantation of jejunum via mesenteric vascular anastomosis or to provide a new blood circulation by pedicle jejunal pedicle and distal jejunum to repair new blood circulation Segment or neck thoracic esophagus
