1Endoscopic submucosal dissection training with pig models in a Western country显示文摘AIM:To test a strategy for endoscopic submucosal dissection(ESD) training in animal models designed to overcome the initial learning curve.METHODS:ESD was attempted in ex vivo and in vivo pig models.Thirty ESD procedures were attempted in the esophagus(n=9) or the stomach(n=21).The ex vivo model was used until initial competence was achieved.In the in vivo model,several ESD procedures were performed in up to 3 sessions.The following variables were analyzed:specimen size,complete and en bloc resection rate,time for circumferential incision,time for submucosal dissection,total ESD duration,and complications.RESULTS:Complete resection was achieved in 28 cases(en bloc 27);2 could not be completed(one perforation,one technical diff iculty).The mean ± SD time for circumferential incision was 36.2±16.8 min(range:8-87 min),and the mean±SD time for submucosal dissection was 45.1±35.7 min(range:9-196 min).The mean±SD size of the resected specimens was 45.2±17.8 mm.The mean±SD total resection time was signif icantly increased for the gastric cases performed in the f irst half of the study(n=13) than in the second half(n=8)(98.9±62.4 min vs 61.7±17.6 min,P=0.04),although the specimen size did not differ.CONCLUSION:Training in animal models could help endoscopists overcome the learning curve before starting ESD in humans.Adolfo Parra-Blanco María Rosa Arnau David Nicolás-Pérez Antonio Z Gimeno-García Nicolás González Juan A Díaz-Acosta Alejandro Jiménez Enrique Quintero 2010World Journal of Gastroenterology2010,16,23:9

3Percutaneous ablation of pancreatic cancer显示文摘Pancreatic ductal adenocarcinoma is a highly aggressive tumor with an overall 5-year survival rate of less than 5%. Prognosis and treatment depend on whether the tumor is resectable or not, which mostly depends on how quickly the diagnosis is made. Chemotherapy and radiotherapy can be both used in cases of nonresectable pancreatic cancer. In cases of pancreatic neoplasm that is locally advanced, non-resectable, but non-metastatic, it is possible to apply percutaneous treatments that are able to induce tumor cytoreduction. The aim of this article will be to describe the multiple currently available treatment techniques(radiofrequency ablation, microwave ablation, cryoablation, and irreversible electroporation), their results, and their possible complications, with the aid of a literature review.Mirko D'Onofrio Valentina Ciaravino Riccardo De Robertis Emilio Barbi Roberto Salvia Roberto Girelli Salvatore Paiella Camilla Gasparini Nicolò Cardobi Claudio Bassi 2016World Journal of Gastroenterology2016,22,44:7

6Definition of colorectal anastomotic leakage: A consensus survey among Dutch and Chinese colorectal surgeons显示文摘AIM To determine the level of consensus on the definition of colorectal anastomotic leakage(CAL) among Dutch and Chinese colorectal surgeons.METHODS Dutch and Chinese colorectal surgeons were asked to partake in an online questionnaire. Consensus in the online questionnaire was defined as > 80% agreement between respondents on various statements regarding a general definition of CAL,and regarding clinical and radiological diagnosis of the complication.RESULTS Fifty-nine Dutch and 202 Chinese dedicated colorectal surgeons participated in the online survey. Consensus was found on only one of the proposed elements of a general definition of CAL in both countries: ‘extravasation of contrast medium after rectal enema on a CT scan'. Another two were found relevant according to Dutch surgeons: ‘necrosis of the anastomosis found during reoperation',and ‘a radiological collection treated with percutaneous drainage'. No consensus was found for all other proposed elements that may be included in a general definition.CONCLUSION There is no universally accepted definition of CAL in the Netherlands and China. Diagnosis of CAL based on clinical manifestations remains a point of discussion in both countries. Dutch surgeons are more likely to report ‘subclinical' leaks as CAL,which partly explains the higher reported Dutch CAL rates.Stefanus J van Rooijen Audrey CHM Jongen Zhou-qiao Wu Jia-fu Ji Gerrit D Slooter Rudi MH Roumen Nicole D Bouvy 2017World Journal of Gastroenterology2017,23,33:4
7Changes in the colon microbiota and intestinal cytokine gene expression following minimal intestinal surgery显示文摘AIM: To investigate the impact of minor abdominal surgery on the caecal microbial population and on markers of gut inflammation.METHODS: Four week old piglets were randomly allocated to a no-surgery 'control' group(n = 6) or a 'transection surgery' group(n = 5).During the transection surgery procedure, a conventional midline incision of the lower abdominal wall was made and the small intestine was transected at a site 225 cm proximal to the ileocaecal valve, a 2 cm segment was removed and the intestine was re-anastomosed.Piglets received a polymeric infant formula diet throughout the study period and were sacrificed at two weeks post-surgery.Clinical outcomes including weight, stool consistency and presence of stool fat globules were monitored.High throughput DNA sequencing of colonic content was used to detect surgery-relateddisturbances in microbial composition at phylum, family and genus level.Diversity and richness estimates were calculated for the control and minor surgery groups.As disturbances in the gut microbial community are linked to inflammation we compared the gene expression of key inflammatory cytokines(TNF, IL1 B, IL18, IL12, IL8, IL6 and IL10) in ileum, terminal ileum and colon mucosal extracts obtained from control and abdominal surgery groups at two weeks post-surgery.RESULTS: Changes in the relative abundance of bacterial species at family and genus level were confined to bacterial members of the Proteobacteria and Bacteroidetes phyla.Family level compositional shifts included a reduction in the relative abundance of Enterobacteriaceae(22.95 ± 5.27 vs 2.07 ± 0.72, P < 0.01), Bacteroidaceae(2.54 ± 0.56 vs 0.86 ± 0.43, P < 0.05) and Rhodospirillaceae(0.40 ± 0.14 vs 0.00 ± 0.00, P < 0.05) following transection surgery.Similarly, at the genus level, changes associated with transection surgery were restricted to members of the Proteobacteria and Bacteroidetes phyla and included decreased relative abundance of Enterobacteriaceae(29.20 ± 6.74 vs 2.88 ± 1.08, P < 0.01), Alistipes(4.82 ± 1.73 vs 0.18 ± 0.13, P < 0.05) and Thalassospira(0.53 ± 0.19 vs 0.00 ± 0.00, P < 0.05).Surgeryassociated microbial dysbiosis was accompanied by increased gene expression of markers of inflammation.Within the ileum IL6 expression was decreased(4.46 ± 1.60 vs 0.24 ± 0.06, P < 0.05) following transection surgery.In the terminal ileum, gene expression of TNF was decreased(1.51 ± 0.13 vs 0.80 ± 0.16, P < 0.01) and IL18(1.21 ± 0.18 vs 2.13 ± 0.24, P < 0.01), IL12(1.04 ± 0.16 vs 1.82 ± 0.32, P < 0.05) and IL10(1.04 ± 0.06 vs 1.43 ± 0.09, P < 0.01) gene expression increased following transection surgery.Within the colon, IL12(0.72 ± 0.13 vs 1.78 ± 0.28, P < 0.01) and IL10(0.98 ± 0.02 vs 1.95 ± 0.14, P < 0.01) gene expression were increased following transection surgery.CONCLUSION: This study suggests that minor abdominal surgery in infants, results in long-term alteration of the colonic microbial composition and persistent gastrointestinal inflammation.Susan Lapthorne Julie E Bines Fiona Fouhy Nicole L Dellios Guineva Wilson Sarah L Thomas Michelle Scurr Catherine Stanton Paul D Cotter Prue M Pereira-Fantini 2015World Journal of Gastroenterology2015,21,14:3
8雄激素受体的目标基因在骨骼肌的表达显示文摘本文通过研究体外和体内模型中潜在的雄激素受体调节基因来确定骨骼肌中雄激素的合成代谢作用机制。睾酮治疗组的去势雄性小鼠与对照组去势雄性小鼠比较,其骨骼肌中肌源性调节因子肌细胞生成素的表达显著下降,而缺乏DNA结合活性的雄性雄激素受体敲除小鼠(AR^△ZF2)与野生型小鼠比较,其骨骼肌中肌源性调节因子肌细胞生成素的表达显著升高,证明了肌细胞生成素是通过雄激素/雄激素受体通路被抑制。通过12小时的骨骼肌细胞(SkMC)的成肌细胞联合双氢睾酮治疗,睾酮治疗组的去势雄性小鼠肌肉中的泛素连接酶Fbxo32被抑制,而肌肉中c—Myc表达较对照组去势雄性小鼠降低,在△R^△ZF2组小鼠肌肉中c-Myc表达升高。调节成肌细胞由增殖向分化转变的一组基因如Tceal7,p57^Kip2,Igf2和钙调磷酸酶Aa的表达在AR^△ZF2组小鼠肌肉中升高,除p57^Kip2外的上述所有基因在睾酮治疗组去势雄性小鼠肌肉中的表达均较对照组降低。因此得出结论,雄激素通过雄激素受体在雄性小鼠体内发挥作用,它在肌肉生长和发展过程中可维持成肌细胞处于增殖状态并推迟成肌细胞向分化状态转变,另外还可抑制泛素连接酶介导的导致肌肉萎缩的通路来保持小鼠肌肉质量,从而一定程度上促进肌肉不断生长达到顶峰。Kesha Rana Nicole KL Lee Jeffrey D Zajac Helen E MacLean 2014Asian Journal of Andrology2014,16,5:3
9Consensus on the definition of colorectal anastomotic leakage: A modified Delphi study显示文摘BACKGROUND Despite the emerging knowledge about colorectal anastomotic leakage(CAL)through the increasing number of clinical and experimental studies, there is no generally accepted definition of CAL. Because of the wide variety of definitions used in literature, comparison of study outcomes and quality of care is complicated.AIM To reach consensus on the definition of CAL using a modified Delphi method.METHODS The RAND/UCLA appropriateness method was used. The expert panel consisted of international colorectal surgeons and researchers who had published three or more articles about CAL. The consensus process consisted of two online distributed questionnaires and a third round with a recommendation. In the questionnaires participants were asked to rate the appropriateness of statements using a 1-9 Likert scale. Consensus was defined as a panel median between 1-3 or 7-9 without disagreement. In the final round a recommendation was formed regarding the definition of CAL and the expert panel was asked if they agreed or disagreed.RESULTSTwenty-three authors participated in the first round and twenty-one finished the second round. After two rounds consensus was reached on 37 items(80%) in nine different categories. The International Study Group of Rectal Cancer definition is the most frequently advised general definition by our panel. Consensus was reached regarding the clinical symptoms of CAL, which serum markers contributes to the suspicion of CAL, which radiological and perioperative findings should be considered as CAL, which grading system is appropriate and if there should be a range of postoperative days in the definition. Eventually, 19 experts completed all three rounds of which 16(84%) agreed with our final recommendations for the definition of CAL.CONCLUSION A consensus-based recommendation for the definition of CAL was formed using our modified Delphi method that can be widely incorporated in the field.Claire PM van Helsdingen Audrey CHM Jongen Wouter J de Jonge Nicole D Bouvy Joep PM Derikx 2020World Journal of Gastroenterology2020,26,23:3

12Central line-associated bloodstream infection among children with biliary atresia listed for liver transplantation显示文摘BACKGROUND Pre-transplant nutrition is a key driver of outcomes following liver transplantation in children.Patients with biliary atresia(BA) may have difficulty achieving satisfactory weight gain with enteral nutrition alone,and parenteral nutrition(PN) may be indicated.While PN has been shown to improve anthropometric parameters of children with BA listed for liver transplantation,less is known about the risks,particularly infectious,associated with this therapy among this specific group of patients.AIM To describe the incidence,microbiology,and risk factors of central line-associated bloodstream infection(CLABSI) among children with BA listed for liver transplantation.METHODS Retrospective review of children aged ≤ 2-years of age with BA who were listed for primary liver transplantation at Texas Children's Hospital from 2008 through2015(n = 96).Patients with a central line for administration of PN(n = 63) were identified and details of each CLABSI event were abstracted.We compared the group of patients who experienced CLABSI to the group who did not,to determine whether demographic,clinical,or laboratory factors correlated with development of CLABSI.RESULTS Nineteen of 63 patients(30%,95%CI:19,43) experienced 29 episodes of CLABSI during 4800 line days(6.04 CLABSI per 1000 line days).CLABSI was predominantly associated with Gram-negative organisms(14/29 episodes,48%)including Klebsiella spp.,Enterobacter spp.,and Escherichia coli.The sole polymicrobial infection grew Enterobacter cloacae and Klebsiella pneumoniae.Grampositive organisms(all Staphylococcus spp.) and fungus(all Candida spp.)comprised 9/29(31%) and 6/29(21%) episodes,respectively.No demographic,clinical,or laboratory factors were significantly associated with an increased risk for the first CLABSI event in Cox proportional hazards regression analysis CONCLUSION There is substantial risk for CLABSI among children with BA listed for liver transplantation.No clinical,demographic,or laboratory factor we tested emerged as an independent predictor of CLABSI.While our data did not show an impact of CLABSI on the short-term clinical outcome,it would seem prudent to implement CLABSI reduction strategies in this population to the extent that each CLABSI event represents potentially preventable hospitalization,unnecessary healthcare dollar expenditures,and may exact an opportunity cost,in terms of missed allograft offers.Nicole D Triggs Stacey Beer Sonam Mokha Kat Hosek Danielle Guffey Charles G Minard Flor M Munoz Ryan W Himes 2019World Journal of Hepatology2019,11,2:2
