| 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 |
| 2 | Endoscopic ultrasound-guided vascular interventions: Current insights and emerging techniques显示文摘Endoscopic ultrasound(EUS)is one of the significant breakthroughs in the field of advanced endoscopy.In the last two decades,EUS has evolved from a diagnostic tool to a real-time therapeutic modality.The luminal gastrointestinal(GI)tract provides a unique opportunity to access multiple vascular structures,especially in the mediastinum and abdomen,thus permitting a variety of EUS-guided vascular interventions.The addition of the doppler and contrast-enhanced capability to EUS has further helped provide real-time visualization of blood flow in vessels through the GI tract.EUS-guided vascular interventions rely on standard endoscopic accessories and interventional tools such as fine-needle aspiration needles and fine-needle biopsy.EUS allows the visualization of various structures in real-time by differentiating tissue densities and vascularity,thus,avoiding radiation exposure.EUS-guided techniques also allow real-time microscopic examination after target biopsy.Furthermore,many necessary interventions can be done during the same procedure after diagnosis.This article provides an overview of EUS-guided vascular interventions such as variceal,non-variceal bleeding interventions,EUSguided portal vein(PV)access with the formation of an intrahepatic portosystemic shunt,and techniques related to diagnosis of GI malignancies.Furthermore,we discuss current insights and future outlook of therapeutic modalities like PV embolization,PV sampling,angiography,drug administration,and portal pressure measurement. | Rupinder Mann Hemant Goyal Abhilash Perisetti Saurabh Chandan Sumant Inamdar Benjamin Tharian | 2021 | World Journal of Gastroenterology2021，27，40： | 4 |
