The reprocessing of flexible gastrointestinal endoscopes is time-consuming and expensive. Endoscopically transmitted infections due to insufficient disinfection are already of clinical importance. A new developed prototype of a flexible, fiberoptic gastroscope was tested in a prospective open randomized trial to evaluate the function. reprocessing and hygienical safety of this disposable, sheathed endoscopic system and was compared with a standard gastroscope. This new endoscopical system utilizes a disposable sheath to cover and protect all working surfaces of the endoscope from contamination. A prospective, randomized trial was performed in our unit to compare the disposable gastroscope (G-F100) with a standard-gastroscope of the newest Generation (GIF-Q 30). Visual analog rating scales were used to record evaluations of endoscope performance and reprocessing by endoscopists and reprocessing personnel. We recorded the time of reprocessing, the time to perform the procedures, depth of insertion, total instrument downtime and any problems which occurred during the procedure. Microbiological swabs were taken from each endoscope. 40 procedures (20 standard, 20 sheathed) were performed. The sheathed gastroscope 8.9 min versus 7.1 min. The overall instrument downtime was significantly shortened by the endosheath (9.8 min versus 47.5 min with the standard gastroscope). The disposable gastroscope-system permits an increase of procedure-frequency up to a factor of 2.9. The standard gastroscope was preferred by the endoscopists and the reprocessing personnel. No microbiological contaminations of the sheathed or the standard gastroscopes could be demonstrated, and no leak of the sheaths was recorded after gastroscopy. The disposable gastroscope has important advantages of decreased instrument turn-around time and potentially increased staff and patient safety.
软性胃肠道内窥镜的再处理既耗时又昂贵。因消毒不充分导致的内窥镜传播感染已具有临床重要性。一种新开发的软性光纤胃镜原型在一项前瞻性开放随机试验中进行了测试，以评估这种一次性带鞘内窥镜系统的功能、再处理情况和卫生安全性，并与标准胃镜进行比较。这种新的内窥镜系统使用一次性护套来覆盖和保护内窥镜的所有工作表面免受污染。我们单位进行了一项前瞻性随机试验，将一次性胃镜（G-F100）与最新一代的标准胃镜（GIF-Q 30）进行比较。使用视觉模拟评分量表记录内镜医师和再处理人员对内镜性能和再处理的评估。我们记录了再处理时间、操作时间、插入深度、仪器总停机时间以及操作过程中出现的任何问题。从每个内窥镜上采集微生物拭子。共进行了40例操作（20例使用标准胃镜，20例使用带鞘胃镜）。带鞘胃镜的再处理时间为8.9分钟，而标准胃镜为7.1分钟。带鞘胃镜使整体仪器停机时间显著缩短（带鞘胃镜为9.8分钟，标准胃镜为47.5分钟）。一次性胃镜系统可使操作频率提高至2.9倍。内镜医师和再处理人员更喜欢标准胃镜。未发现带鞘胃镜或标准胃镜有微生物污染，胃镜检查后也未记录到护套泄漏。一次性胃镜具有减少仪器周转时间以及可能提高工作人员和患者安全性的重要优势。
