后路显微椎间盘镜的发展及临床应用现状

Progress of microendoscopic discectomy and clinical applications

后路显微椎间盘镜技术(microendoscopic discectomy,MED)实质是"开窗"术式与内窥镜技术的整合。该微创技术是目前治疗腰椎间盘突出症较为成熟的技术之一。本文从其发展历史、技术优势、操作特点、适应证、禁忌证、并发症、发展趋势等方面对MED技术进行了详细介绍,同时探讨了目前MED技术存在的问题及其今后的研究发展方向。旨在阐述MED技术及其拓展技术在治疗腰椎间盘突出症方面有其独特微创优势,是腰椎微创技术发展方向之一,在内镜技术迅速发展的形势下值得临床继续大力推广使用。

Microendoscopic discectomy（ MED） is the integration of endoscopy and conventional discectomy in essence,which is one of relatively mature technologies of treatment of lumbar disc herniation. In this paper,the history,advantages,operating characteristics,indication,contraindications,development trends of MED are described in detail,and current problems and future research and development directions of MED are also discussed. The purpose is to emphasize that MED and expand technology have its unique minimally invative advantages in the treatment of lumbar disc herniation,and are one of development directions of lumbar minimally invasive surgery,both of which are worthwhile to be continually and extensively promoted in clinical applications with the rapid development of endoscopic techniques.
