OHSU的发现有助于改善如何筛查慢性胃灼热或初期食道癌患者 http://www.dxy.cn/bbs/post/view? ... amp;tpg=1&age=0 OHSU findings may improve how people with chronic heartburn, precancer of the esophagus are screened OHSU Digestive Health Center researchers are first to reveal that using a 'skinny scope' in an office setting is cheaper, technically feasible, diagnostically accurate and less risky than the gold standard -- sedated upper endoscopy 奥勒冈州保健科学大学(OHSU)检查结果可能改善那些带有胃灼热、食道癌前病变的人群是如何被屏蔽的情况。OHSU消化卫生中心的研究员们最先揭示:跟金标准—需镇静的上消化道内窥镜检查比较,在办公环境中使用一种膜状窥镜有诸多优点,便宜,技术上可行,诊断上准确,并且风险更小。 Resarchers in the Oregon Health & Science University Digestive Health Center are first to report that screening people with chronic heartburn or pre-cancer of the esophagus in an office setting using a "skinny scope" is as accurate, less expensive and less risky than a traditional sedated screening in a procedure room ?and patients prefer it. The findings are published online and in print in this month's issue of the American Journal of Gastroenterology. OHSU消化卫生中心的研究员们首先报导,在办公环境中使用一种膜状窥镜,用来筛选带有胃灼热、食道癌前病变的人群,与在操作间进行实施传统的需镇静下的上消化道内窥镜检查相比,具有一样的精确性,更便宜的价格,更小的风险;更重要的是病人倾向于前者。这项研究结果发表在网络上,并且在美国胃肠病学杂志的月刊上出版。 The study, led by principal investigator Blair A. Jobe, M.D., a surgeon in the OHSU Digestive Health Center and member of the OHSU Cancer Institute, found that study participants preferred unsedated, small-caliber upper endoscopy, commonly referred to as the skinny scope, to the standard screening method for upper digestive disease, sedated upper endoscopy. l 这项研究策划者是首席研究员Blair A. Jobe博士,OHSU消化卫生中心的外科医生,成员由OHSU癌症学会组成。研究发现参与者更喜欢不需镇静的小口径上消化道内窥镜检查,通常指向的是膜状窥镜,而不喜欢用于上消化道疾病检查的标准筛选方法,也就是镇静的上消化道内窥镜。 Study participants in Jobe's Esophageal Care Clinic listed a number of reasons for preferring the skinny scope, including not having to undergo anesthesia, not missing a day of work and not having to arrange for transportation to and from home. But the best benefit, according to at least one study participant, was the ability to watch the entire procedure in real time on a color monitor and receive immediate feedback from the clinician. 在Jobe食道关怀诊所的研究参与者,列举了倾向于膜状窥镜的一些理由,包括不必经受麻醉,不会错过一天的工作,不必安排前往和回家的运送。但是根据至少一个研究参与者的意见,最受益的是能够实时在一个彩色监视器上看到整个操作程序,然后可以立即从临床医师那里得到反馈信息。 "There was no pain. My wife and I watched the entire thing. I found it informative and appreciated not having to wait for the anesthesia to wear off to learn the results," said Dennis Murphy, 58, Tigard, Ore. Murphy was diagnosed with Barrett's esophagus, a precursor to cancer, four years ago. As part of the study protocol, he underwent both procedures on separate occasions. At the end of the study, he said he preferred the skinny scope and would request it at his next checkup. 58岁的丹尼斯(俄勒冈州,Tigard市)说“没有痛苦,我的妻子和我一起观察了整个过程,我发现它能提供资料信息,更感激地是不用等着被麻醉,不用消磨时间去获悉结果”四年前,Mrphy先生被诊断为巴雷特(氏)食管,一种癌前病变。根据研究的部分诊断记录,他在不同的场合接受过上述两种检查。当研究结束时,他说他倾向于接受膜状窥镜检查,在他下次复查时他会要求进行该种检查。 With approximately 10 million Americans struggling with chronic heartburn, also known as GERD (gastroesophageal reflux disease) ?a condition closely associated with the development of one of the most lethal forms of cancer: esophageal cancer ?the need for a cost-effective screening and surveillance system was long apparent to Jobe, who also is an associate professor of surgery in the OHSU School of Medicine, Portland Veterans Affairs Medical Center. 大约有一千万的美国人正和慢性胃灼热病抗争,这种病又叫胃食管返流疾病(GERD),是和一种最致命的癌症—食道癌发展密切相关的情况,对于Jobe而言,需要一种成本-效益筛选方法和监护系统一直是显而易见的。Jobe是OHSU医学院外科学和波特兰退伍军人事宜医学中心的副教授。 "However, given the relative rarity of esophageal cancer compared with the high prevalence of GERD," Jobe explained. "Routine screening within the general population using traditional upper endoscopy would be too costly." “然而,考虑到与GERD高患病率相比,食道癌的相对稀少,”Jobe解释道“在一般人群中使用传统的上消化道内窥镜进行常规筛选花费将会太昂贵了 Eager to find an economically viable means of screening and monitoring this patient population, Jobe and colleagues endeavored to devise a method that would reduce the cost, inconvenience and complications associated with sedated endoscopy ?and they succeeded. 迫切于找到一种经济的筛选方法来监视患病人群,Jobe和他的同事们尽力去发明一种方法,能够降低与镇静内窥镜相关的花费、不便、复杂性,最终他们成功了. "This trial has established that unsedated small-caliber endoscopy used in an office setting is technically feasible, well-tolerated and accurate in the screening and diagnosis of Barrett's esophagus. It's a more personal approach and represents the potential to eliminate the infrastructure and costs required for intravenous sedation. It's also more immediate. As soon as you're done, you can tell the patient what you've found." 这项试验已经被证明,用于办公环境的不需要麻醉的小口径内窥镜,在筛选和诊断巴雷特(氏)食管方面,技术上是可行的,病人容易忍受,诊断准确。它是更加个体化的途径,体现出消除用于静脉麻醉的下部结构和花费的潜力。它也更加具有即时性。一做完检查,你就可以告诉病人你发现了什么。 To perform a sedated upper endoscopy, an endoscope, 9.8 mm in diameter, is passed through the mouth and throat to the esophagus, stomach and small intestine. The procedure requires the resources and infrastructure of an outpatient procedure unit, two assistants, intravenous sedation and post-procedure monitoring, with a total cost in the thousands of dollars. And, as with any procedure for which the patient is sedated, the risk of complications, though rare, is higher. 为了执行一个需麻醉的上消化道内窥镜检查,一个直径9.8米的内窥镜通过口腔、喉部然后到达食道、胃和小肠。这个程序需要资源和病人体外操作单元的下部结构,两个助手,静脉麻醉,以及操作后的监护,整个花费下来要成千上万美元。此外,对麻醉后的病人的任何操作,并发症的风险,尽管稀少,但是要高于不需麻醉的检查。 By comparison, the skinny scope procedure is performed by a single clinician in an office setting and does not require sedation. Patients inhale a topical anesthetic that numbs their nasal passages and throat. The clinician then passes a smaller-caliber endoscope, 4.9 mm in diameter, through the nose, pharynx and throat. The cost for this procedure is in the hundreds of dollars. 相比之下,膜状窥镜操作起来只需要一位临床医师,在工作环境中进行,不需要镇静。病人吸入一种局部麻醉药,能够麻醉他们的鼻道和喉部。临床医师这时就可以将更小口径的内窥镜(直径4.9毫米)通过鼻子、咽、喉。这项操作的费用才几百美元。 Only a handful of centers in the United States routinely employ the skinny scope as part of clinical practice. According to Jobe, this is due in part to the perception that the unsedated skinny scope increases patient anxiety and discomfort. In addition, some endoscopists, unfamiliar with the nasal approach, may lack the skills necessary to perform it. And, up until recently, endoscopes were not long enough to examine the entire upper digestive tract. i 在美国,仅仅少数几个中心常规开展这种膜状窥镜检查。根据Jobe的观点,这部分是由于不麻醉的膜状窥镜给病人增加了焦虑和不舒服的感觉。此外,一些内镜师,不熟悉鼻道途径,可能缺少实行的必须技术。直到最近,内窥镜不再足够用于整个上消化道检查。 One hundred thirty-four men and women with long-standing histories of GERD symptoms and acid-reducing medication use were enrolled in this randomized, cross-over trial. Ninety-eight percent of subjects successfully completed unsedated small-caliber endoscopy (skinny scope) in an office setting. More than 70 percent of participants said they would choose the unsedated skinny scope over the conventional approach on a subsequent endoscopy. The prevalence of Barrett's esophagus discovered by both approaches was equal and there were no undetected cases of cancer. 134名长期患有GERD综合征的、采用胃酸减少疗法的男、女患者,注册进入这个随机、交叉试验。受试者中98名在工作环境成功完成了不需麻醉的小口径内窥镜检查(膜状窥镜)。超过70%的参与者说,他们会选择不需要麻醉的膜状窥镜检查,而不选择依赖后来的内窥镜的传统途径检查。巴雷特(氏)食管的患病率,通过上述两种途径是一致的,并且没有未被发现的癌症案例。 \ 下面是全文,有几个请指教:skinny scope 奥勒冈州保健科学大学(OHSU)检查结果可能改善那些带有胃灼热、食道癌前病变的人群是如何被屏蔽的情况。OHSU消化卫生中心的研究员们最先揭示:跟金标准—需镇静的上消化道内窥镜检查比较,在办公环境中使用一种膜状窥镜有诸多优点,便宜,技术上可行,诊断上准确,并且风险更小。 mEKnk5Y%Q OHSU消化卫生中心的研究员们首先报导,在办公环境中使用一种膜状窥镜,用来筛选带有胃灼热、食道癌前病变的人群,与在操作间进行实施传统的需镇静下的上消化道内窥镜检查相比,具有一样的精确性,更便宜的价格,更小的风险;更重要的是病人倾向于前者。这项研究结果发表在网络上,并且在美国胃肠病学杂志的月刊上出版。 这项研究策划者是首席研究员Blair A.
