| 2 | Diffusion-weighted magnetic resonance imaging to predict response of hepatocellular carcinoma to chemoembolization显示文摘AIM: To investigate whether intra-procedural diffusion- weighted magnetic resonance imaging can predict response of hepatocellular carcinoma (HCC) during trans- catheter arterial chemoembolization (TACE). METHODS: Sixteen patients (15 male), aged 59 ±11 years (range: 42-81 years) underwent a total of 21 separate treatments for unresectable HCC in a hybrid magnetic resonance/interventional radiology suite. Ana- tomical imaging and diffusion-weighted imaging (b = 0, 500 s/mm2) were performed on a 1.5-T unit. Tumor enhancement and apparent diffusion coefficient (ADC, mm2/s) values were assessed immediately before and at 1 and 3 mo after TACE. We calculated the percent change (PC) in ADC values at all time points. We compared follow-up ADC values to baseline values using a paired t test (α = 0.05). RESULTS: The intra-procedural sensitivity, specificity, and positive and negative predictive values (%) for detecting a complete or partial 1-mo tumor response using ADC PC thresholds of ±5%, ±10%, and ±15% were 77, 67, 91, and 40; 54, 67, 88, and 25; and 46, 100, 100, and 30, respectively. There was no clear predictive value for the 3-mo follow-up. Compared to baseline, the immediate post-procedure and 1-mo mean ADC values both increased; the latter obtaining statistical significance (1.48 ± 0.29 mm2/s vs 1.65 ± 0.35 × 10-3 mm2/s, P < 0.014). CONCLUSION: Intra-procedural ADC changes of > 15% predicted 1-mo anatomical HCC response with the greatest accuracy, and can provide valuable feedback at the time of TACE. | Johnathan C Chung Neel K Naik Robert J Lewandowski Mary F Mulcahy Laura M Kulik Kent T Sato Robert K Ryu Riad Salem Andrew C Larson Reed A Omary | 2010 | World Journal of Gastroenterology2010，16，25： | 13 |
| 3 | 澳大利亚临床共识指南:儿童卒中的诊断和急性期处理显示文摘卒中是导致儿童死亡的十大原因之一,幸存的致残患儿将面临几十年的残疾生活,给患儿及其家庭带来了巨大负担。由于安全性和有效性的证据有限,以及诊断的延误,目前卒中患儿无法接受再灌注治疗。儿童卒中诊断和急性期处理的澳大利亚临床共识指南,旨在最大限度地减少临床诊疗中的不确定性,并记录与成人卒中不同的危险因素、病因和假性卒中情况的最佳证据。临床问题的阐述来自于对2007年至2017年数据库的系统检索,但仅限于英语和儿科研究。该指南应用SIGN方法和国家健康与医学研究委员会系统对证据进行筛选和分类,通过推荐、评估、发展和评价系统(GRADE系统)对推荐进行强弱分级。该指南提供了60多项基于证据的推荐,以帮助参与院前和急症处理的临床医师快速识别儿童卒中,选择最合适的初步检查方案来确定诊断、明确病因,并选择最恰当的干预措施以挽救脑组织、预防复发。同时,指南也提供了颅内压和先天性心脏病管理方面的推荐。该指南的实施需要将院前和急诊系统重组,包括建立区域性卒中网络,建立儿科卒中疾病编码,快速MRI,以及对能够提供再灌注治疗的初级儿科卒中中心进行认证。该指南能够审核治疗的基准时间线,获得急性期的干预措施及预后判断。它还将促进澳大利亚儿童卒中登记的发展,并与国际登记处建立数据联系,以便准确收集卒中发病率、治疗和结果相关的数据。 | Medley TL Miteff C Andrews I Ware T Cheung M Monagle P Mandelstam S Wray A Pridmore C Troedson C Dale RC Fahey M Sinclair A Walsh P Stojanovski S Macka MT 徐佳丽(译) 吴川杰(译) 肖潇(译) 吕俊萱(译) 张博维(译) 吉训明(译) | 2019 | 中国脑血管病杂志2019，16，4： | 9 |
| 4 | 在结肠和直肠的癌症的淋巴节点收获: 当前的考虑显示文摘 The prognostic significance of identifying lymph node(LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease.An established body of evidence exists,demonstrating an association between a higher total LN count and improved survival,particularly for node negative colon cancer.In node positive disease,however,the lymph node ratios may represent a better prognostic indicator,although the impact of this on clinical treatment has yet to be universally established.By extension,strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging.However,debate prevails as to whether or not these extrapolations are clinically relevant,particularly when very high LN counts are sought.Current guidelines recommend a minimum of 12 nodes harvested as the standard of care,yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival.Findings from modern treatments,including down-staging in rectal cancer using pre-operative chemoradiotherapy,paradoxically suggest that lower LN count,or indeed complete absence of LNs,are associated with improved survival;implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate.The pursuit of a sufficient LN harvest represents good clinical practice;however,recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little in? uence on modern approaches to treatment. | James R McDonald Andrew G Renehan Sarah T O’Dwyer Najib Y Haboubi | 2012 | World Journal of Gastrointestinal Surgery2012，4，1： | 8 |

| 6 | Tryptophan:A gut microbiota-derived metabolites regulating inflammation显示文摘Inflammatory bowel diseases(IBD), which comprise Crohn's disease and ulcerative colitis, are chronic intestinal disorders with an increased prevalence and incidence over the last decade in many different regions over the world. The etiology of IBD is still not well defined, but evidence suggest that it results from per-turbation of the homeostasis between the intestinal microbiota and the mucosal immune system, with the involvement of both genetic and environmental factors. Genome wide association studies, which involve large-scale genome-wide screening of potential polymorphism, have identified several mutations associated with IBD. Among them, Card9, a gene encoding an adapter molecule involved in innate immune response to fungi(via type C-lectin sensing) through the activation of IL-22 signaling pathway, has been identified as one IBD susceptible genes. Dietary compounds, which represent a source of energy and metabolites for gut bacteria, are also appreciated to be important actors in the etiology of IBD, for example by altering gut microbiota composition and by regulating the generation of short chain fatty acids. A noteworthy study published in the June 2016 issue of Nature Medicine by Lamas and colleagues investigates the interaction between Card9 and the gut microbiota in the generation of the microbiota-derived tryptophan metabolite. This study highlights the role of tryptophan in dampening intestinal inflammation in susceptible hosts. | Lucie Etienne-Mesmin Benoit Chassaing Andrew T Gewirtz | 2017 | World Journal of Gastrointestinal Pharmacology and Therapeutics2017，8，1： | 7 |
| 7 | Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death. | Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee | 2016 | World Journal of Gastroenterology2016，22，25： | 7 |

| 10 | Novel ecosystems created by coal mines in central Queensland’s Bowen Basin显示文摘Introduction:Open-cut coal mining began in central Queensland’s Bowen Basin approximately 50 years ago.Over this period of time,mine rehabilitators have used a variety of tree,shrub,and groundcover species to create‘novel ecosystems’to stabilise soils and provide vegetative cover for pre-supposed final end-land uses.We examine post-mining rehabilitation from multiple soil and vegetation monitoring activities in the Bowen Basin to assess the similarity of landforms,plant composition,and trends in plant diversity compared to unmined reference communities.Methods:Rehabilitated spoil dumps and reference sites were assessed using soil and vegetation data contained in compliance monitoring reports from Goonyella Riverside,Moura,Oaky Creek,Rolleston,and Blackwater mines.Slopes,soil chemistry,and plant species mixes of rehabilitation aged from 2 to 22 years were compared to selected reference communities.Results:Mines in this region have generally proposed one of two post-rehabilitation end-land uses:either pasture for cattle grazing or reconstructed native communities which potentially provide native fauna habitat.Landform data from a selection of these mine sites suggest that when their rehabilitation was compared to nearby reference sites median slope values were between 2.5 and 7 times steeper and soil pH,electrical conductivity,and phosphorus levels were significantly higher.The steeply sloped landforms,poor soil characteristics,depauperate native species pool,and uniform presence of exotic pasture grasses in the rehabilitation indicate that most of these newly created ecosystems should not be used for cattle grazing and also have few natural values.Conclusions:Legislative and community expectations have changed progressively over time and,although much of the rehabilitation is currently dominated by an assemblage of exotic buffel grass(Cenchrus ciliaris)and Acacia spp.,recent environmental authorities suggest these‘novel ecosystems’will be judged against native reference sites.Upon completion of mining activities the resilience of these new ecosystems to drought,fire,and grazing will need to be demonstrated prior to lease relinquishment. | Peter D Erskine Andrew T Fletcher | 2013 | Ecological Processes2013，2，1： | 5 |
| 11 | Crohn’s and colitis in children and adolescents显示文摘Crohn's disease and ulcerative colitis can be grouped as the inflammatory bowel diseases(IBD).These conditions have become increasingly common in recent years,including in children and young people.Although much is known about aspects of the pathogenesis of these diseases,the precise aetiology is not yet understood,and there remains no cure.Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life,including in infancy.Pain,diarrhoea and weight loss are typical symptoms of paediatric Crohn's disease whereas bloody diarrhoea is more typical of colitis in children.However,atypical symptoms may occur in both conditions:these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum.Growth and nutrition are commonly compromised at diagnosis in both Crohn's disease and colitis.Consideration of possible IBD and completion of appropriate investi-gations are essential to ensure prompt diagnosis,thereby avoiding the consequences of diagnostic delay.Patterns of disease including location and progression of IBD in childhood differ substantially from adultonset disease.Various treatment options are available for children and adolescents with IBD.Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn's disease.Medical and surgical therapies need to considered within the context of a growing and developing child.The overall management of these chronic conditions in children should include multi-disciplinary expertise,with focus upon maintaining control of gut inflammation,optimising nutrition,growth and quality of life,whilst preventing disease or treatment-related complications. | Andrew S Day Oren Ledder Steven T Leach Daniel A Lemberg | 2012 | World Journal of Gastroenterology2012，18，41： | 4 |

| 13 | Serrated neoplasia of the colorectum显示文摘Serrated polyps of the colorectum form a group of related lesions which include aberrant crypt foci (ACF), conventional hyperplastic polyps, mixed (admixed) polyps, serrated adenomas and sessile serrated adenomas. In recent years the molecular differences between these morphologically similar lesions have been highlighted, and their differing biological potential has been realised. In particular, the sessile serrated adenoma has become recognised as the precursor lesion to a group of sporadic colorectal carcinomas characterised by morphological and molecular features distinct from conventional adenomas. These recent findings have challenged the long held paradigm that all colorectal carcinomas arise via the traditional adenoma-carcinoma sequence. In addition, they present a major challenge for the early detection and management of colorectal cancer, which is no longer regarded as a homogeneous entity. | Nathan T Harvey Andrew Ruszkiewicz | 2007 | World Journal of Gastroenterology2007，13，28： | 4 |
| 14 | Critical analysis of feeding jejunostomy following resection of upper gastrointestinal malignancies显示文摘AIM To assess nutritional recovery,particularly regarding feeding jejunostomy tube(FJT)utilization,following upper gastrointestinal resection for malignancy. METHODS A retrospective review was performed of a prospectively-maintained database of adult patients who underwent esophagectomy or gastrectomy(subtotal or total)for cancer with curative intent,from January 2001 to June 2014. Patient demographics,the approach to esophagectomy,the extent of gastrectomy,FJT placement and utilization at discharge,administration of parenteral nutrition(PN),and complications were evaluated. All patients were followed for at least ninety days or until death.RESULTS The 287 patients underwent upper GI resection,comprised of 182 esophagectomy(n=107 transhiatal,58.7%; n=56 Ivor-Lewis,30.7%)and 105 gastrectomy [n=63 subtotal(SG),60.0%; n=42 total(TG),40.0%]. 181 of 182 esophagectomy patients underwent FJT,compared with 47 of 105 gastrectomy patients(99.5% vs 44.8%,P < 0.0001),of whom most had undergone TG(n=39,92.9% vs n=8 SG,12.9%,P < 0.0001). Median length of stay was similar between esophagectomy and gastrectomy groups(14.7 d vs 17.1 d,P=0.076). Upon discharge,87 esophagectomy patients(48.1%)were taking enteral feeds,with 53(29.3%)fully and 34(18.8%)partially dependent. Meanwhile,20 of 39 TG patients(51.3%)were either fully(n=3,7.7%)or partially(n=17,43.6%)dependent on tube feeds,compared with 5 of 8 SG patients(10.6%),all of whom were partially dependent. Gastrectomy patients were significantly less likely to be fully dependent on tube feeds at discharge compared to esophagectomy patients(6.4% vs 29.3%,P=0.0006). PN was administered despite FJT placement more often following gastrectomy than esophagectomy(n=11,23.4% vs n=7,3.9%,P=0.0001). FJT-specific complications requiring reoperation within 30 d of resection occurred more commonly in the gastrectomy group(n=6),all after TG,compared to 1 esophagectomy patient(12.8% vs 0.6%,P=0.0003). Six of 7 patients(85.7%)who experienced tube-related complications required PN.CONCLUSION Nutritional recovery following esophagectomy and gastrectomy is distinct. Operations are associated with unique complication profiles. Nutritional supplementation alternative to jejunostomy should be considered in particular scenarios. | Andrew M Blakely Saad Ajmal Rachel E Sargent Thomas T Ng Thomas J Miner | 2017 | World Journal of Gastrointestinal Surgery2017，9，2： | 4 |

| 16 | Gastric intestinal metaplasia is associated with gastric dysplasia but is inversely correlated with esophageal dysplasia显示文摘AIM To determine which clinical factors might be associated with gastric intestinal metaplasia(IM) in a North American population.METHODS Pathology and endoscopy databases at an academicmedical center were reviewed to identify patients with and without gastric IM on biopsies for a retrospective cohort study. Patient demographics, insurance status, and other clinical factors were reviewed.RESULTS Four hundred and sixty-eight patients with gastric IM(mean age: 61.0 years ± 14.4 years, 55.5% female) and 171 without gastric IM(mean age: 48.8 years ± 20.8 years, 55.0% female) were compared. The endoscopic appearance of atrophic gastritis correlated with finding gastric IM on histopathology(OR = 2.05, P = 0.051). Gastric IM was associated with histologic findings of chronic gastritis(OR = 2.56, P < 0.001), gastric ulcer(OR = 6.97, P = 0.015), gastric dysplasia(OR = 6.11, P = 0.038), and gastric cancer(OR = 6.53, P = 0.027). Histologic findings of Barrett's esophagus(OR = 0.28, P = 0.003) and esophageal dysplasia(OR = 0.11, P = 0.014) were inversely associated with gastric IM. Tobacco use(OR = 1.73, P = 0.005) was associated with gastric IM.CONCLUSION Patients who smoke or have the endoscopic finding of atrophic gastritis are more likely to have gastric IM and should have screening gastric biopsies during esophagogastroduodenoscopy(EGD). Patients with gastric IM are at increased risk for having gastric dysplasia and cancer, and surveillance EGD with gastric biopsies in these patients might be reasonable. | Justin M Gomez James T Patrie Wissam Bleibel Jeanetta W Frye Bryan G Sauer Vanessa M Shami Edward B Stelow Christopher A Moskaluk Andrew Y Wang | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，2： | 3 |
| 17 | Effects of Yttrium-90 selective internal radiation therapy on non-conventional liver tumors显示文摘The liver is a common site of metastasis, with essentially all metastatic malignancies having been known to spread to the liver. Nearly half of all patients with extrahepatic primary cancer have hepatic metastases. The severe prognostic implications of hepatic metastases have made surgical resection an important first line treatment in management. However, limitations such as the presence of extrahepatic spread or poor functional hepatic reserve exclude the majority of patients as surgical candidates, leaving chemotherapy and locoregional therapies as next best options. Selective internal radiation therapy(SIRT) is a form of catheter-based locoregional cancer treatment modality for unresectable tumors, involving trans-arterial injection of microspheres embedded with a radioisotope Yttrium-90. The therapeutic radiation dose is selectively delivered as the microspheres permanently embed themselves within the tumor vascular bed. Use of SIRT has been conventionally aimed at treating primary hepatic tumors(hepatocellular carcinoma) or colorectal and neuroendocrine metastases. Numerous reviews are available for these tumor types. However, little is known or reviewed on non-colorectal or nonneuroendocrine primaries. Therefore, the aim of this paper is to systematically review the current literature to evaluate the effects of Yttrium-90 radioembolization on non-conventional liver tumors including those secondary to breast cancer, cholangiocarcinoma, ocular and percutaneous melanoma, pancreatic cancer, renal cell carcinoma, and lung cancer. | Andrew Kuei Sammy Saab Sung-Ki Cho Stephen T Kee Edward Wolfgang Lee | 2015 | World Journal of Gastroenterology2015，21，27： | 2 |
| 18 | Multicenter evaluation of recurrence in endoscopic submucosal dissection and endoscopic mucosal resection in the colon:A Western perspective显示文摘BACKGROUND While colon endoscopic mucosal resection(EMR)is an effective technique,removal of larger polyps often requires piecemeal resection,which can increase recurrence rates.Endoscopic submucosal dissection(ESD)in the colon offers the ability for en bloc resection and is well-described in Asia,but there are limited studies comparing ESD vs EMR in the West.AIM To evaluate different techniques in endoscopic resection of large polyps in the colon and to identify factors for recurrence.METHODS The study is a retrospective comparison of ESD,EMR and knife-assisted endoscopic resection performed at Stanford University Medical Center and Veterans Affairs Palo Alto Health Care System between 2016 and 2020.Knife-assisted endoscopic resection was defined as use of electrosurgical knife to facilitate snare resection,such as for circumferential incision.Patients≥18 years of age undergoing colonoscopy with removal of polyp(s)≥20 mm were included.The primary outcome was recurrence on follow-up.RESULTS A total of 376 patients and 428 polyps were included.Mean polyp size was greatest in the ESD group(35.8 mm),followed by knife-assisted endoscopic resection(33.3 mm)and EMR(30.5 mm)(P<0.001).ESD achieved highest en bloc resection(90.4%)followed by knife-assisted endoscopic resection(31.1%)and EMR(20.2%)(P<0.001).A total of 287 polyps had follow-up(67.1%).On follow-up analysis,recurrence rate was lowest in knife-assisted endoscopic resection(0.0%)and ESD(1.3%)and highest in EMR(12.9%)(P=0.0017).En bloc polyp resection had significantly lower rate of recurrence(1.9%)compared to non-en bloc(12.0%,P=0.003).On multivariate analysis,ESD(in comparison to EMR)adjusted for polyp size was found to significantly reduce risk of recurrence[adjusted hazard ratio 0.06(95%CI:0.01-0.57,P=0.014)].CONCLUSION In our study,EMR had significantly higher recurrence compared to ESD and knife-assisted endoscopic resection.We found factors including resection by ESD,en bloc removal,and use of circumferential incision were associated with significantly decreased recurrence.While further studies are needed,we have demonstrated the efficacy of ESD in a Western population. | Mike T Wei Margaret J Zhou Andrew A Li Andrew Ofosu Joo Ha Hwang Shai Friedland | 2023 | World Journal of Gastrointestinal Endoscopy2023，15，6： | 2 |

| 20 | Percutaneous transluminal angioplasty balloons for endoscopic ultrasound-guided pancreatic duct interventions显示文摘BACKGROUND Endoscopic ultrasound(EUS)-guided main pancreatic duct(PD)access may be used when conventional endoscopic retrograde cholangiopancreatography(ERCP)techniques fail.The use of a percutaneous transluminal angioplasty balloon(PTAB),originally developed for vascular interventions,can be used to facilitate transmural(e.g.,transgastric)PD access and to dilate high-grade pancreatic strictures.AIM To describe the technique,efficacy,and safety of PTABs for EUS-guided PD interventions.METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database.PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire.The primary outcome was technical success.Secondary outcomes included incidence of adverse events(AEs)and need for early reintervention.RESULTS A total of 23 patients were identified(48%female,mean age 55.8 years).Chronic pancreatitis was the underlying etiology in 13(56.5%)patients,surgically altered anatomy(SAA)with stricture in 7(30.4%),and SAA with post-operative leak in 3(13.0%).Technical success was achieved in 20(87%)cases.Overall AE rate was 26%(n=6).All AEs were mild and included 1 pancreatic duct leak,2 cases of post-procedure pancreatitis,and 3 admissions for post-procedural pain.No patients required early re-intervention.CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails. | Jad P AbiMansour Barham K Abu Dayyeh Michael J Levy Andrew C Storm John A Martin Bret T Petersen Ryan J Law Mark D Topazian Vinay Chandrasekhara | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，8： | 2 |
