| 1 | Minimally invasive surgery for gastric cancer: A comparison between robotic, laparoscopic and open surgery显示文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery. | Amilcare Parisi Daniel Reim Felice Borghi Ninh T Nguyen Feng Qi Andrea Coratti Fabio Cianchi Maurizio Cesari Francesca Bazzocchi Orhan Alimoglu Johan Gagnière Graziano Pernazza Simone D'Imporzano Yan-Bing Zhou Juan-Santiago Azagra Olivier Facy Steven T Brower Zhi-Wei Jiang Lu Zang Arda Isik Alessandro Gemini Stefano Trastulli Alexander Novotny Alessandra Marano Tong Liu Mario Annecchiarico Benedetta Badii Giacomo Arcuri Andrea Avanzolini Metin Leblebici Denis Pezet Shou-Gen Cao Martine Goergen Shu Zhang Giorgio Palazzini Vito D'Andrea Jacopo Desiderio | 2017 | World Journal of Gastroenterology2017，23，13： | 17 |
| 2 | Importance of bifurcation angle in bifurcation stenting显示文摘Bifurcation coronary lesions are relatively frequent in today's interventional cardiology practice,averaging between 10%-15% of all percutaneous coronary interventions(PCIs).1 Several problems inherent in the treatment of bifurcation lesions are periprocedural side branch(SB)compromise(composite of SB closure or appearance of significant ostial stenosis after main vessel(MV)stenting causing ischemia)frequently related to periprocedural myonecrosis,relatively higher restenosis rates especially in two-stent techniques,and higher rates of stent thrombosis in different time frames.1-4 The lead author and other investigators demonstrated that both periprocedural result and long-term results could be influenced by bifurcation angulations.The purpose of this study is to show why and how bifurcation angulations are important for bifurcation stenting. | Dobrin Vassilev Alexander Alexandrov Dan Le Katrina Nguyen James Nguyen Hung Phan Robert J.

| 4 | Efficacy and safety of tenofovir in chronic hepatitis B: Australian real world experience显示文摘AIM To evaluate the long-term treatment outcomes of tenofovir therapy in patients in a real world Australian tertiary care setting.METHODS We performed a retrospective analysis of treatment outcomes among treatment-na?ve and treatment-experienced patients receiving a minimum 3 mo tenofovir therapy through St Vincent's Hospital Melbourne, Australia. We included patients receiving tenofovir [tenofovir disoproxil fumarate(TDF)] monotherapy, as well as patients treated with TDF in combination with a second antiviral agent. Patients were excluded if they demonstrated human immune-deficiency virus/hepatitis C virus/hepatitis delta virus coinfection or were less than 18 years of age. We considered virological and biochemicalresponse, as well as safety outcomes. Virological response was determined by measurement of hepatitis B virus(HBV) DNA using sensitive assays; biochemical response was determined via serum liver function tests; histological response was determined from liver biopsy and fibroscan; safety analysis focused on glomerular renal function and bone mineral density. The primary efficacy endpoint was complete virological suppression over time, defined by HBV DNA < 20 IU/m L. Secondary efficacy endpoints included rates of biochemical response, and HB e antigen(HBe Ag)/HB surface antigen loss and seroconversion over time.RESULTS Ninety-two patients were identified who fulfilled the enrolment criteria. Median follow-up was 26 mo(range 3-114). Mean age was 46(24-78) years, 64(70%) were male and 77(84%) were of Asian origin. 55(60%) patients were treatment-na?ve and 62 patients(67%) were HBe Ag-negative. Complete virological suppression was achieved by 45/65(71%) patients at 12 mo, 37/46(80%) at 24 mo and 25/28(89%) at 36 mo. Partial virological response(HBV DNA 20-2000 IU/m L) was achieved by 89/92(96.7%) of patients. Multivariate analysis showed a significant relationship between virological suppression at end of follow-up and baseline HBV DNA level(OR = 0.897, 95%CI: 0.833-0.967, P = 0.0046) and HBe Ag positive status(OR = 0.373, 95%CI: 0.183-0.762, P = 0.0069). There was no difference in response comparing treatment-na?ve and treatment-experienced patients. Three episodes of virological breakthrough occurred in the setting of noncompliance. Tenofovir therapy was well tolerated.CONCLUSION Tenofovir is an efficacious, safe and well-tolerated treatment in an Australian real-world tertiary care setting. Our data are similar to the reported experience from registration trials. | Grace C Lovett Tin Nguyen David M Iser Jacinta A Holmes Robert Chen Barbara Demediuk Gideon Shaw Sally J Bell Paul V Desmond Alexander J Thompson | 2017 | World Journal of Hepatology2017，9，1： | 7 |
| 5 | Cancer and age related colonic crypt deficiencies in cytochrome c oxidase Ⅰ显示文摘AIM: To investigate whether defi ciency of expressionof cytochrome c oxidase I (CcOI) in colonic crypts is associated with colon cancer.METHODS: The pattern and level of expression of CcOI in non-neoplastic colonic crypts,and in dysplastic tissues,was assessed using standard immunohis-tochemical methods.Biopsies were obtained from individuals undergoing colonoscopies for screening purposes or for a medically indicated reason.Tissue samples were also obtained from surgical colonic resections.Samples from resections were taken from colonic mucosa 1 and 10 cm from tumors and from the tumors themselves.Samples were evaluated for frequency of crypts with reduced or absent expression of CcOI.In most crypts the loss was apparent throughout the entire crypt,while in a small minority the loss was segmental.The strong immunoreactivity using this monoclonal antibody makes the scoring unambiguous.The percent of crypts with reduced or absent expression of CcOI or (infrequent) segmented loss of expression was then calculated.Data analyses were performed using SPSS statistical package 17.0.RESULTS: The average frequency of CcOI deficient crypts (CcOI-DC) is low in individuals between 20 and 39 years of age,with 0.48% ± 0.40% CcOI-DC for women and 1.80% ± 0.35% for men.CcOI-DC increases after age 40 years,so that between the ages of 40 and 44 years the average frequency of CcOI- DC goes up to 5.89% ± 0.84% in women and 2.15% ± 1.27% in men.By 80-84 years of age,the average frequency of CcOI-DC goes up in women to 15.77% ± 0.97% and in men to 22.6% ± 0.65%.The increases in CcOI-DC from ages 40-44 years compared to 80-84 years in women and men are significantly different with P < 0.01.For women over age 60 years,deficiency of CcOI expression is greater in those women who have had a cancer in their colon.The frequency of CcOI-DC,measured in men,increased in tissues adjacent to colon cancer,being 4.03% ± 0.27% in individuals free of neoplasia in the age range 55-64 yearsand 14.13% ± 0.35% in resected histologically normal tissue of men with cancer in the same age range,P < 0.001.Similar signifi cant differences were noted in older age ranges.The frequency of CcOI-DC crypts in the cecum and sigmoid colon of an individual are signifi cantly correlated,with an R2 = 0.414 for women and R2 = 0.528 for men,P < 0.001.This suggests that the factors determining the level of CcOI deficiency act throughout the colon.Most defective crypts are in clusters of two or more,a likely consequence of crypt fission.In the non-neoplastic margins of cancers,crypts are frequently defi cient for CcOI,and such crypts may appear in large clusters,some containing more than 100 defi cient crypts.CcOI defi ciency is also apparent in colon cancers and sometimes involves a large section of the tumor.Overall,CcOI deficient cells can be visualized in segments of crypts,in whole crypts that increase in frequency with age,in crypts undergoing f ission,in clusters of crypts where the clusters increase in size with age,in increased frequency near tumors,in large clusters in the intimate margins of tumors,and in the tumors themselves.There is no clear dividing line between early stages that can be considered aspects of aging and later stages that can be considered aspects of the progression to cancer.This ambiguity may re ect a rather general situation leading to adult cancer where the early stages of cellular change appear to be relatively innocuous features of the aging process but over decades may evolve into malignancy.CONCLUSION: CcOI defi cient crypts increase in frequency with age,and clusters of defi cient crypts are associated with,and may give rise to,colon cancer. | Carol Bernstein Alexander Facista Huy Nguyen Beryl Zaitlin Nadia Hassounah Cristy Loustaunau Claire Margaret Payne Bhaskar Banerjee Steve Goldschmid V Liana Tsikitis Robert Krouse Harris Bernstein | 2010 | World Journal of Gastrointestinal Oncology2010，2，12： | 5 |
| 6 | Nutritional and health benefits of semi-elemental diets: A comprehensive summary of the literature显示文摘AIM:To critically review and summarize the literature on nutritional and health outcomes of semi-elemental formulations on various nutritionally vulnerable patient populations who are unable to achieve adequate nutrition from standard oral diets.METHODS:We conducted a comprehensive literature search of Pubmed and Embase databases.We manually screened articles that examined nutritional and health outcomes(e.g.,growth,disease activity,gastrointestinal impairment,mortality,and economic impact)among various patient groups receiving semi-elemental diets.This review focused on full-text articles of randomized controlled clinical trials and other intervention studies,but pertinent abstracts and case studies were also included.Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population in this systematic review.RESULTS:Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population.The efficacy of semi-elemental whey hydrolyzed protein(WHP)diet have been reported in various nutritionally high risk patient populations including-Crohn’s disease,short bowel syndrome,acute and chronic pancreatitis,cerebral palsy,cystic fibrosis,cerebrovascular accidents,human immunodeficiency virus,critically ill,and geriatrics.Collectively,the evidence from the medical literature indicates that feeding with a semi-elemental diet performs as well or better than parenteral or amino acid based diets in terms of toler-ance,digestion,and nutrient assimilation measures across various disease conditions.CONCLUSION:Based on this comprehensive review of the literature,patient populations who have difficulty digesting or absorbing standard diets may be able to achieve improved health and nutritional outcomes through the use of semi-elemental WHP diets. | Dominik D Alexander Lauren C Bylsma Laura Elkayam Douglas L Nguyen | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，2： | 3 |

| 8 | Gastric per-oral endoscopic myotomy: Current status and future directions显示文摘Gastroparesis, or symptomatic delayed gastric emptying in the absence of mechanical obstruction, is a challenging and increasingly identified syndrome. Medical options are limited and the only medication approved by the Food and Drug Administration for treatment of gastroparesis is metoclopramide, although other agents are frequently used off label. With this caveat, first-line treatments for gastroparesis include dietary modifications, antiemetics and promotility agents, although these therapies are limited by suboptimal efficacy and significant medication side effects. Treatment of patients that fail first-line treatments represents a significant therapeutic challenge. Recent advances in endoscopic techniques have led to the development of a promising novel endoscopic therapy for gastroparesis via endoscopic pyloromyotomy, also referred to as gastric per-oral endoscopic myotomy or per-oral endoscopic pyloromyotomy. The aim of this article is to review the technical aspects of the per-oral endoscopic myotomy procedure for the treatment of gastroparesis, provide an overview of the currently published literature, and outline potential next directions for the field. | Alexander Podboy Joo Ha Hwang Linda A Nguyen Patricia Garcia Thomas A Zikos Afrin Kamal George Triadafilopoulos John O Clarke | 2019 | World Journal of Gastroenterology2019，25，21： | 3 |
