Known and documented factors attributable to ERCP-related complications include the experience and technique of the endoscopist as well as anatomic and pathologic factors pertaining to the papilla. In an effort to minimize trauma, facilitate deep entry to the biliary system, and improve the efficiency of therapeutic ERCP, new cannulation, sphincterotomy, and guide wire devices have been developed, based on principles of safe and successful therapeutic ERCP learned over the years. By totally re-engineering familiar accessories into smaller, more flexible, and more versatile devices, the 0.025-inch guide wire-based DASH system attempts to minimize the trauma at deep CBD cannulation and thereby increase the safety and success of achieving deep cannulation and sphincterotomy. Limited clinical experience to date suggests that the DASH system can provide full-function ERCP while reducing risks and costs. Attention to cannulation has led to the development of the RX Biliary System which provides the endoscopist and the assistant with increased control of the guide wire and exchange compared with traditional devices, resulting in less stress, less hand and wrist force used for contrast injection, and easier guide wire management, all of which have been shown in clinical trials to improve the speed and efficiency of ERCP while reducing complications.
已知的与内镜逆行胰胆管造影(ERCP)相关并发症的可归因因素和已记录因素包括内镜医师的经验和技术以及与乳头相关的解剖学和病理学因素。为了尽量减少创伤、便于深入进入胆道系统并提高治疗性ERCP的效率,基于多年来学到的安全且成功的治疗性ERCP原则,已开发出新型插管、括约肌切开术和导丝装置。通过将熟悉的附件完全重新设计成更小、更灵活且用途更广的装置,基于0.025英寸导丝的DASH系统试图在深入胆总管插管时尽量减少创伤,从而提高实现深入插管和括约肌切开术的安全性和成功率。迄今为止有限的临床经验表明,DASH系统在降低风险和成本的同时可提供全功能的ERCP。对插管的关注促使了RX胆道系统的开发,与传统装置相比,该系统为内镜医师和助手提供了对导丝和交换更强的控制能力,从而减轻压力、减少造影剂注射时手部和腕部用力,并更便于导丝管理,所有这些在临床试验中均已证明可提高ERCP的速度和效率,同时减少并发症。
