Background: Duodenoscope-related multidrug-resistant organism(MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 ***: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

我们回顾了目前关于土壤生物多样性及其在生态系统过程中的作用、对于人类目标的重要性及对胁迫和扰动的恢复能力等的研究进展。现存物种的数量远远大于人们已经描述的数量,即使是对于肉眼可见的分类群也是如此。而且也普遍缺乏在生物地理学上的综合描述。迫切需要在分类学和对新一代系统科学家培训上做更大努力。尤其是应当集中致力于就我们所知。对生态系统功能起关键作用的土壤生物类群方面。为了确定这种类群,需要对土壤生物区系的影响圈(sphere of Influence,SOI),如根的生物区系、有机物质破碎者(shredder)和土壤生物扰动者(bioturbator)加以识别,这些影响圈比如可能通过与植物的相互作用而控制着生态系统的过程。在这些SOI中,我们分析出了土壤有机体的功能类群。最迫切需要研究的问题是将物种按功能类群进行区分,并确定功能类群中的物种冗余。这种迫切性是根据为阐述与集约化农业、森林扰动、环境污染和全球环境变化有关的土壤功能丧失程度的需要而确定的。目前认为最处于危险的土壤生物区系是那些大型动物群的有机物破碎者、土壤生物扰动者、某些专门的细菌(如硝化细菌和固氮菌)以及形成真菌的菌根中贫乏物种的功能类群。在开展这些优先性研究时,需要使用长期的和大尺度的田间试验,以及地理统计学和地理信息系统等现代方法进行试验研究。
