| 1 | 采用电凝增强的“哑铃样”自膨式金属支架在内镜超声引导下实施一步法胰周积液引流:有无荧光辅助的结局比较显示文摘背景:荧光透视技术常用于胰周积液(PFC)的内镜引流。电凝增强的“哑铃样”自膨式金属支架(ELAMS)可实现“一步法”操作,并有可能无需荧光透视。本研究比较了在有或没有荧光透视的协助下,ELAMS的治疗结果。方法:纳入2014年1月至2017年2月间行囊肿胃吻合术的PFC患者。基于有无采用荧光透视将入组病例分为两组。技术成功,定义为术中顺利置入ELAMS;临床成功,定义为术后临床症状缓解或8周后CT显示胰腺囊肿缩小75%以上。记录出血、支架移位、感染等不良事件。结果:研究期间共有21例患者采用ELAMS进行PFC引流,其中男性13例。平均年龄(51.6±14.2)岁。13例患者为包裹性坏死,8例为胰腺假性囊肿。PFC平均直径(11.3±3.3)cm。7例(33%)患者术中采用了荧光透视,手术时间显著延长[(43.1±10.4)min vs(33.3±10.5)min,P=0.025];手术时间的延长不受PFC大小、部位和类型的影响。荧光透视并没有影响技术成功率,所有21例患者均成功置入ELAMS。相比荧光下操作,无荧光操作的临床缓解率(91%vs 71%,P=0.52)和影像缓解率(57%vs 71%,P=0.65)的差异均无统计学意义。无荧光操作患者中有3例出现了支架移位/误置。结论:囊肿胃吻合术中放置ELAMS无需荧光透视。无荧光操作可以显著缩短手术时间,而且并不影响技术成功率和临床成功率。 | Babatunde Olaiya Parit Mekaroonkamol Bai-Wen Li Julia Massaad Cicily TVachaparambil Jennifer Xu Vladamir Lamm Hui Luo Shan-Shan Shen Hui-Min Chen Steve Keilin Field FWillingham Qiang Cai | 2020 | Gastroenterology Report2020，8，6： | 0 |
| 2 | Cannulation time is a more accurate measure of cannulation difficulty in endoscopic retrograde cholangiopancreatography than the number of attempts显示文摘Background:Cannulation of the common bile duct(CBD)is the initial and sometime challenging step in endoscopic retrograde cholangiopancreatography(ERCP)procedure.Endoscopists often use cannulation attempts and cannulation time to grade cannulation difficulty,but a standard system has yet to be established.The objective of this study was to compare cannulation times with numbers of cannulation attempts,as measures of cannulation difficulty.Methods:We conducted a prospective study in a tertiary referral center,enrolling 58 patients who were undergoing ERCP for a variety of indications.Cannulation time and the number of cannulation attempts were recorded for each patient.A subset of 14 ERCPs had two observers assessing attempts at cannulation.Cannulation time,number of attempts and inter-observer variability in assessment of attempts were compared and studied.Results:The degree of agreement between two the methods(cannulation times and number of cannulation attempts)was unacceptable.There were considerable discrepancies between attempt tallies from two observers but the mean difference was statistically insignificant.Conclusion:The grade of cannulation difficulty for a given ERCP procedure may differ when different methods are used(total cannulation time vs number of attempts);thus,grading by different methods should not be used interchangeably.Cannulation time is a more objective and more accurate assessment tool for grading cannulation difficulty than the number of attempts to cannulate the papilla. | Chenlu Tian Anthony Gamboa Biswashree Chaudhury Field FWillingham Steve Keilin Qiang Cai | 2013 | Gastroenterology Report2013，1，3： | 0 |
