Critical to realizing increasing benefits of enteral nutrition are techniques for feeding tube placement. Feeding tubes can be placed by bedside, endoscopic, fluoroscopic, and surgical methods. This review encompasses noteworthy studies on endoscopic approaches to enteral feeding published from January 2005 to the present.
Studies involving placement of nasoenteric feeding tubes include description of new methods for endoscopic nasoenteric feeding tube placement using a push technique with a stiffened tube, a modification of the 'drag and pull' method using a distal suture tie, and placement using an ultrathin transnasal endoscopic technique compared with fluoroscopic placement. Recent studies involving percutaneous endoscopic gastrostomy tube placement have demonstrated equivalent outcomes of endoscopic and fluoroscopic approaches, description of unsedated placement using transnasal technique, and risk of percutaneous endoscopic gastrostomy site metastasis in head and neck cancer patients. Studies on percutaneous jejunal feeding tubes demonstrate: high complication rate and short functional duration of percutaneous endoscopic gastrojejunostomy and reported outcomes of direct percutaneous endoscopic jejunostomy placement.
Enteral nutrition access can be obtained by a variety of methods depending on local expertise and resources. Endoscopic approaches have equivalent or better outcomes than other methods; however, these methods may still have limitations and distinct complications.
实现肠内营养效益不断提高的关键在于喂养管放置技术。喂养管可通过床边、内镜、透视及手术方法放置。本综述涵盖了2005年1月至今发表的关于肠内喂养内镜方法的重要研究。
涉及鼻肠喂养管放置的研究包括使用带加强管的推送技术进行内镜鼻肠喂养管放置的新方法描述、使用远端缝线结扎对“拖和拉”方法的改进,以及与透视放置相比使用超薄经鼻内镜技术进行的放置。近期涉及经皮内镜下胃造口管放置的研究表明,内镜和透视方法的结果相当,描述了使用经鼻技术在未镇静状态下的放置,以及头颈部癌症患者经皮内镜下胃造口部位转移的风险。关于经皮空肠喂养管的研究表明:经皮内镜下胃空肠造口术的并发症发生率高且功能持续时间短,以及直接经皮内镜下空肠造口术放置的报告结果。
根据当地的专业知识和资源,可通过多种方法获得肠内营养通路。内镜方法比其他方法具有相当或更好的结果;然而,这些方法可能仍有局限性和独特的并发症。
