| 6 | Endoscopic ultrasound in the diagnosis of cholangiocarcinoma as the etiology of biliary strictures:a systematic review and meta-analysis显示文摘Background and aim:Extrahepatic cholangiocarcinoma(CCA)typically presents as biliary strictures.Endoscopic ultrasound(EUS)-fine needle aspiration(FNA)may contribute to the diagnosis of CCA as the etiology of extrahepatic biliary strictures.Our aim was to study the uselfulness of EUS-FNA in diagnosing CCA as the etiology of biliary strictures.Patients and methods:In this meta-analysis,PUBMED and EMBASE databases were examined to find studies published to April 2014 where diagnostic correlation of CCA was available.Studies reporting only‘‘positive for malignancy’’were included in our analysis.The main outcome measurements were sensitivity,specificity and likelihood ratio.Results:Six studies were included,covering 196 patients.The overall pooled sensitivity and negative likelihood ratio(LR-)of EUS-FNA for diagnosis of CCA were 66%[95%confidence interval(CI)57-74%]and 0.34(95%CI 0.26-0.43),respectively.In five studies(146 patients),where a mass lesion was detected during EUS,the pooled sensitivity and LR-of EUS-FNA for diagnosis of CCA were 80%[95%CI 72-87%]and 0.20(95%CI 0.13-0.28),respectively.In the 49 patients with a negative brush cytology,the pooled sensitivity and LR-of EUS-FNA for diagnosis of CCA were 59%[95%CI 44-73%]and 0.41(95%CI 0.27-0.56),respectively.Conclusions:Our study suggests that EUS-FNA is useful in the evaluation of CCA as the etiology of biliary strictures.EUS-FNA may improve the diagnosis of CCA in patients with negative cytology and no mass on cross-sectional imaging. | Udayakumar Navaneethan Basile Njei Preethi G.K Venkatesh Vennisvasanth Lourdusamy Madhusudhan R Sanaka | 2015 | Gastroenterology Report2015，3，3： | 1 |

| 15 | Clinical indicators for progression of nonalcoholic steatohepatitis to cirrhosis显示文摘Non-alcoholic fatty liver disease(NAFLD),is a disease spectrum characterized by fat accumulation in hepatocytes presenting as hepatic steatosis to advance disease with active hepatic inflammation,known as nonalcoholic steatohepatitis.Chronic steatohepatitis will lead to progressive hepatic fibrosis causing cirrhosis and increased risk for developing hepatocellular carcinoma(HCC).Fatty liver disease prevalence has increased at alarming rates alongside obesity,diabetes and metabolic syndrome to become the second most common cause of cirrhosis after alcohol related liver disease worldwide.Given this rise in prevalence,it is becoming increasingly more important to find non-invasive methods to diagnose disease early and stage hepatic fibrosis.Providing clinicians with the tools to diagnose and treat the full spectrum of NAFLD will help prevent known complications such as cirrhosis and HCC and improve quality of life for the patients suffering from this disease.This article discusses the utility of current noninvasive liver function testing in the clinical progression of fatty liver disease along with the imaging modalities that are available.Additionally,we summarize available treatment options including targeted medical therapy through four different pathways,surgical or endoscopic intervention. | Tasur Kumar Seen Muntazir Sayed Muhammad Bilal Jonathan Vincent Reyes Priyanka Bhandari Vennis Lourdusamy Ahmed Al-khazraji Umer Syed Yasar Sattar Raghav Bansal | 2021 | World Journal of Gastroenterology2021，27，23： | 1 |
| 16 | Biomarkers in bile-complementing advanced endoscopic imaging in the diagnosis of indeterminate biliary strictures显示文摘Biliary strictures present a diagnostic challenge and a conundrum, particularly when an initial work up including abdominal imaging and endoscopic retrograde cholangiopancreatography based sampling are nondiagnostic. Advances in endoscopic imaging have helped us diagnose these strictures better. However, even with modern technology, some strictures remain a diagnostic challenge. The proximity of bile fluid to the bile duct epithelia makes it an attractive option to investigate for bio-markers, which might be representative of the functions/abnormal changes taking place in the biliary system. A number of biomarkers in bile have been discovered recently in approaching biliary strictures with their potential future diagnostic utility, further supported by the immunohistochemical analysis of the resected tissue specimens. Novel biliary biomarkers especially carcinoembryonic cell adhesion molecule 6 and neutrophil gelatinase-associated lipocalin seem promising in differentiating malignant from benign biliary strictures. Recent developments in lipidomic profiling of bile are also very promising. Biliary biomarkers appear to complement endoscopic imaging in diagnosing malignant etiologies of biliary stricture. Future studies addressing these biomarkers need to be incorporated to the current endoscopic techniques to determine the best approach in determining the etiology of biliary strictures. | Vennisvasanth Lourdusamy Benjamin Tharian Udayakumar Navaneethan | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，4： | 1 |

| 20 | 炎症性肠病患者中结直肠癌患者的切除率:基于人群的研究显示文摘背景与目的:炎症性肠病(IBD)患者结直肠癌的发生风险升高。本研究旨在分析美国IBD相关结直肠癌手术切除率的变化趋势。方法:我们收集了美国住院样本数据库1995-2012年间的相关病例资料。采用多因素Joinpoint回归模型分析年龄标化的IBD相关结直肠癌的手术切除率的时间变化趋势。主要结局指标是IBD相关结直肠癌的手术切除率。结果:共纳入1995-2012年间3,597,168例IBD出院病例,其中275,479例接受了结直肠癌切除手术。IBD人群中的结直肠癌切除率从1995年至2012年显著下降,各个年龄组的年切除例数均显著下降,18-39岁组、40-49岁组、50-74岁组和75岁以上组每100,000例IBD患者中结直肠癌年切除例数从1995年至2012年分别减少393、359、293和159例(均P<0.001);其中,近端结直肠癌年切除例数分别减少149、130、95和50例(均P<0.001),远端结直肠癌年切除例数分别减少104、123、123和82例(均P<0.001)。多因素Poisson回归分析显示,校正年龄和性别因素后,结直肠癌切除率从1995-2012年间年均下降了3.9%。结论:从1995-2012年间,IBD患者中的结直肠癌切除率逐年下降,且近端和远端结直肠癌切除率均呈现下降趋势。这一人群水平的下降趋势反应了美国IBD相关结直肠癌发病率的下降。 | Udayakumar Navaneethan Xiang Zhu Dennisdhilak Lourdusamy Vennisvasanth Lourdusamy Bo Shen Ravi Kiran | 2018 | Gastroenterology Report2018，6，4： | 0 |
