1Assessment of the diagnostic performance and interobserver variability of endocytoscopy in Barrett's esophagus:A pilot ex-vivo study显示文摘AIM:To investigate a classification of endocytoscopy(ECS)images in Barrett’s esophagus(BE)and evaluate its diagnostic performance and interobserver variability.METHODS:ECS was applied to surveillance endoscopic mucosal resection(EMR)specimens of BE ex-vivo.The mucosal surface of specimen was stained with 1%methylene blue and surveyed with a catheter-type endocytoscope.We selected still images that were most representative of the endoscopically suspect lesion and matched with the final histopathological diagnosis to accomplish accurate correlation.The diagnostic performance and inter-observer variability of the new classification scheme were assessed in a blinded fashion by physicians with expertise in both BE and ECS and inexperienced physicians with no prior exposure to ECS.RESULTS:Three staff physicians and 22 gastroenterology fellows classified eight randomly assigned unknown still ECS pictures(two images per each classification)into one of four histopathologic categories as follows:(1)BEC1-squamous epithelium;(2)BEC2-BE without dysplasia;(3)BEC3-BE with dysplasia;and(4)BEC4-esophageal adenocarcinoma(EAC)in BE.Accuracy of diagnosis in staff physicians and clinical fellows were,respectively,100%and 99.4%for BEC1,95.8%and83.0%for BEC2,91.7%and 83.0%for BEC3,and95.8%and 98.3%for BEC4.Interobserver agreement of the faculty physicians and fellows in classifying each category were 0.932 and 0.897,respectively.CONCLUSION:This is the first study to investigate classification system of ECS in BE.This ex-vivo pilot study demonstrated acceptable diagnostic accuracy and excellent interobserver agreement.Yutaka Tomizawa Prasad G Iyer Louis M Wongkeesong Navtej S Buttar Lori S Lutzke Tsung-Teh Wu Kenneth K Wang 2013World Journal of Gastroenterology2013,19,46:2

9回肠储袋肛管吻合术后储袋扭转:对其发生率、诊断和治疗结局的系统综述显示文摘背景:结直肠切除加回肠储袋肛管吻合术(IPAA)是难治性溃疡性结肠炎和家族性腺瘤性息肉病的标准外科术式。然而,储袋扭转时有发生,尽管发生率很低。本研究旨在探讨IPAA患者术后储袋扭转的发生率、临床表现和治疗。方法:于2018年8月10日通过医学文献图书馆系统检索已发表的文献,由两名独立的研究人员分别进行文献筛选、数据提取、方法学质量评估。同时,检索美国Mayo Clinic 2008年1月至2018年8月间的电子病历发现了1例储袋扭转病例。结果:一项报道了IPAA长期结局的大样本研究显示,储袋扭转发生率为0.18%(3/1700)。本研究共纳入22例储袋扭转患者进行分析,其中18例原发疾病为溃疡性结肠炎。全组病例中位年龄32岁,女性占73%。IPAA术后出现储袋扭转的中位时间为36个月,出现首发症状至诊断储袋扭转的中位时间为24小时。腹痛是最常报道的症状(76%)。多数病例是经腹部CT作出初步诊断(76%,13/17)。11例患者行内镜治疗,仅1例(9%)成功。20例患者行手术治疗,最常采用的手术方式是储袋固定术和储袋切除术。5例(25%)患者接受了再次IPAA手术。结论:储袋扭转是IPAA术后一种罕见但严重的并发症,出现梗阻症状时应考虑储袋扭转的可能。内镜治疗成功率非常低;如果能早期诊断、早期手术,手术治疗疗效确切。Muhammad Jawoosh Samir Haffar Parakkal Deepak Alyssa Meyers Amy L.Lightner David W.Larson Laura H.Raffals MHassan Murad Navtej Buttar Fateh Bazerbachi 2019Gastroenterology Report2019,7,6:1
