| 1 | Video capsule endoscopy vs double-balloon enteroscopy in the diagnosis of small bowel bleeding:A systematic review and metaanalysis显示文摘AIM To compare the diagnostic accuracy of video capsule endoscopy(VCE) and double-balloon enteroscopy(DBE) in cases of obscure gastrointestinal bleeding(OGIB) of vascular origin.METHODS MEDLINE(via PubMed), LILACS(via BVS) and Cochrane/CENTRAL virtual databases were searched for studies dated before 2017. We identified prospective and retrospective studies, including observational, cohort, single-blinded and multicenter studies, comparing VCE and DBE for the diagnosis of OGIB, and data of all the vascular sources of bleeding were collected. All patients were subjected to the same gold standard method. Relevant data were then extracted from each included study using a standardized extraction form. We calculated study variables(sensitivity, specificity, prevalence, positive and negative predictive values and accuracy) and performed a meta-analysis using Meta-Disc software.RESULTS In the per-patient analysis, 17 studies(1477 lesions) were included. We identified3150 exams(1722 VCE and 1428 DBE) in 2043 patients and identified 2248 sources of bleeding, 1467 of which were from vascular lesions. Of these lesions, 864(58.5%) were diagnosed by VCE, and 613(41.5%) were diagnosed by DBE. The pretest probability for bleeding of vascular origin was 54.34%. The sensitivity of DBE was 84%(95%CI: 0.82-0.86; heterogeneity: 78.00%), and the specificity was92%(95%CI: 0.89-0.94; heterogeneity: 92.0%). For DBE, the positive likelihood ratio was 11.29(95%CI: 4.83-26.40; heterogeneity: 91.6%), and the negative likelihood ratio was 0.20(95%CI: 0.15-0.27; heterogeneity: 67.3%). Performing DBE after CE increased the diagnostic yield of vascular lesion by 7%, from 83% to90%.CONCLUSION The diagnostic accuracy of detecting small bowel bleeding from a vascular source is increased with the use of an isolated video capsule endoscope compared with isolated DBE. However, concomitant use increases the detection rate of the bleeding source. | Hélcio Pedrosa Brito Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura Wanderley Marques Bernardo Dalton Marques Chaves Rogério Kuga Ethan Dwane Maahs Robson Kiyoshi Ishida Eduardo Turiani Hourneaux de Moura Eduardo Guimaraes Hourneaux de Moura | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，12： | 10 |
| 2 | Microscopic colitis:A large retrospective analysis from a health maintenance organization experience显示文摘AIM:To examine the demographic data on a large multi-ethnic population of patients with microscopic colitis (MC) in Southern California and to determine the association of MC with inflammatory bowel disease (IBD) and colorectal cancer.METHODS: All patients diagnosed with MC by colonic biopsy from 1996-2005 were identified utilizing a pathology database. All biopsies were reviewed by experienced pathologists utilizing standard histologic criteria. Patients' medical records were reviewed and data regarding patient age, co-morbidities, sex, ethnicity, and medications were analyzed. An age-and sexmatched standard control group was also generated. Chi-square test was used to evaluate the associations of co-morbidities between lymphocytic colitis (LC), collagenous colitis (CC) and the control group.RESULTS: A total of 547 cases of MC were identif ied,376 patients with LC and 171 patients with CC. The female/male ratio was 3:1 in CC and 2.7:1 in LC patients. Celiac disease (P<0.001), irritable bowel syndrome (IBS) (P<0.001), and thyroid diseases (P<0.001) were found to have a higher occurrence in MC compared to the control group. No statistical differences in the occurrence of colorectal cancer, diabetes and IBD were found between the MC group and the control group.CONCLUSION: This is the largest group of patients with MC known to the authors that has been studied to date. Conditions such as celiac disease, IBS, and thyroid diseases were found to be related to MC. Furthermore, neither an increased risk of colorectal cancer nor IBD was associated with MC in this study. | Kevin T Kao Benito A Pedraza Amy C McClune David A Rios Yi-Qiong Mao Robert H Zuch Michael H Kanter Sony Wirio Chris N Conteas | 2009 | World Journal of Gastroenterology2009，15，25： | 5 |
