1 食管内支架应用的历史1983年 Frimberger 首先报告了用食管内支架治疗吞咽困难的病人。其后,Domschke 等进行了动物实验和临床方面的研究。目前,此项技术已广泛地应用于临床。我国九十年代开始也逐步开展了此项技术,如于永征、王懿铎先后报告利用硅胶内支架治疗晚期食管癌和食管气管瘘,取得了满意效果。最初内支架大多是以硅胶为主要原料制成的,其弹性小,因唾液、食物残渣等在食管粘膜与支架间长期滞留,使局部粘膜溃烂,且支架易脱落。后来各种金属支架不断问世。如:膨胀式金属螺旋管支架、自展式 Z 形支架(Gi-antruco-Z stent)及被覆支架、自展式网状金属支架(wall-stent)、球囊扩张金属网状支架(streeker stent)、自膨式 ultra-flex 支架等。金属网状支架解决了塑料支架所致唾液、食物
1 History of Esophageal Stent Applications 1983 Frimberger first reported on the use of esophageal stents to treat dysphagia patients. Later, Domschke et al. conducted animal experiments and clinical studies. At present, this technology has been widely used in clinical practice. Since the 1990s, this technology has been gradually developed in China. For example, Yu Yongzheng and Wang Hao have reported using silicone stents to treat advanced esophageal cancer and esophageal tracheal fistula, and have achieved satisfactory results. Most of the initial stents were made of silicone as the main raw material, and their elasticity was small. Due to saliva, food residues, etc., they stayed between the esophageal mucosa and the stent for a long time, causing local mucosal ulceration and easy to fall off the stent. Later, various metal stents came out. Such as: expandable metal spiral tube stent, self-propagating Z-shaped stent (Gi-antruco-Z stent) and covered stent, self-expanding metal stent (wall-stent), metal stent stent stent (streeker stent stent stent ) Self-expanding ultra-flex stents. Metal mesh stent solves saliva and food caused by plastic stent
