| 1 | Bilateral vs unilateral placement of metal stents for inoperable highgrade hilar biliary strictures: A systemic review and meta-analysis显示文摘BACKGROUND Bilateral vs unilateral biliary stenting is used for palliation in malignant biliary obstruction.No clear data is available to compare the efficacy and safety of bilateral biliary stenting over unilateral stenting.AIM To assess the efficacy and safety of bilateral vs unilateral biliary drainage in inoperable malignant hilar obstruction.METHODS PubMed,Embase,Scopus,and Cochrane databases,as well as secondary sources(bibliographic review of selected articles and major GI proceedings),were searched through January 2019.The primary outcome was the re-intervention rate.Secondary outcomes were a technical success,early and late complications,and stent malfunction rate.Pooled odds ratio(OR)and 95%confidence interval(CI)were calculated for each outcome.RESULTS A total of 9 studies were included(2 prospective Randomized Controlled Study,5 retrospective studies,and 2 abstracts),involving 782 patients with malignant hilar obstruction.Bilateral stenting had significantly lower re-intervention rate compared with unilateral drainage(OR=0.59,95%CI:0.40-0.87,P=0.009).There was no difference in the technical success rate(OR=0.7,CI:0.42-1.17,P=0.17),early complication rate(OR=1.56,CI:0.31-7.75,P=0.59),late complication rate(OR=0.91,CI:0.58-1.41,P=0.56)and stent malfunction(OR=0.69,CI:0.42-1.12,P=0.14)between bilateral and unilateral stenting for malignant hilar biliary strictures.CONCLUSION Bilateral biliary drainage had a lower re-intervention rate as compared to unilateral drainage for high grade inoperable malignant biliary strictures,with no significant difference in technical success,and early or late complication rates. | Munish Ashat Sumant Arora Jagpal S Klair Christopher A Childs Arvind R Murali Frederick C Johlin | 2019 | World Journal of Gastroenterology2019，25，34： | 5 |

| 18 | Impact of vitamin D on the hospitalization rate of Crohn's disease patients seen at a tertiary care center显示文摘AIM To study the association between vitamin D level and hospitalization rate in Crohn's disease(CD) patients.METHODS We designed a retrospective cohort study using adult patients(> 19 years) with CD followed for at least one year at our inflammatory bowel disease center. Vitamin D levels were divided into: low mean vitamin D level(< 30 ng/m L) vs appropriate mean vitamin D level(30-100 ng/m L). Generalized Poisson Regression Models(GPR) for Rate Data were used to estimate partially adjusted and fully adjusted incidence rate ratios(IRR) of hospitalization among CD patients. We also examined IRRs for vitamin D level as a continuous variable.RESULTS Of the 880 CD patients, 196 patients with vitamin D level during the observation period were included. Partially adjusted model demonstrated that CD patients with a low mean vitamin D level were almost twice more likely to be admitted(IRR = 1.76, 95%CI: 1.38-2.24) compared to those with an appropriate vitamin D level. The fully adjusted model confirmed this association(IRR = 1.44, 95%CI: 1.11-1.87). Partially adjusted model with vitamin D level as a continuous variable demonstrated,higher mean vitamin D level was associated with a 3% lower likelihood of admission with every unit(ng/m L) rise in mean vitamin D level(IRR = 0.97, 95%CI: 0.96-0.98). The fully adjusted model confirmed this association(IRR = 0.98, 95%CI: 0.97-0.99). CONCLUSION Normal or adequate vitamin D stores may be protective in the clinical course of CD. However, this role needs to be further characterized and understood. | Krishna VR Venkata Sumant S Arora Feng-Long Xie Talha A Malik | 2017 | World Journal of Gastroenterology2017，23，14： | 1 |
