ARTIFICIAL ESOPHAGUS

摘要

An artificial esophagus characterized by comprising a tube having a layer of microfibrillar collagen on its outer side. It is capable of retaining over a certain period the effect characteristic of collagen such that esophageal epithelium regeneration is accelerated in a defective region of the esophagus to thereby effect esophageal neogenesis. It is decomposed and absorbed by the body in accordance with the neogenesis and thus leaves no foreign substance. It does not require an operator to use a complicated suturing technique. It is free from bleeding or air leakage from the suture, and facilitates stent removal after esophageal reconstruction.
