I learned that problem of system split is not unique in PLM world. Here is my favorite passage from there.

我发现系统分离的问题并不是PLM独有的。

The phary-esophagus passage could be restored by retaining the mucosa, pectoralis major myocutaneous flap, laryngotracheal flap, split skin flap, stomach transposition and colon interposition etc.

根据病变具体情况，应用局部黏膜牵拉缝合、裂层皮片、胸大肌肌皮瓣、喉气管黏膜瓣、胃、结肠等方法和材料可重建咽-食管通道。
