| 1 | Intraductal endoscopic radiofrequency ablation for the treatment of hilar non-resectable malignant bile duct obstruction显示文摘AIM: To evaluate the safety and technical success of endoscopic radiofrequency ablation(RFA) for palliative treatment of malignant hilar bile duct obstruction. METHODS: In this study, a recently CE and FDA-approved endoscopic RFA catheter was first tested in an ex vivo pig liver model to study the effect of electrosurgical variables on the extent of the area of induced necrosis. Subsequently, a retrospective analysis was conducted of all patients treated with endoscopic RFA for malignant biliary obstruction at our center between February 2012 and April 2013. All patients received an additional plastic stent implantation into the biliary tree following RFA. RESULTS: In the pig model, ablation time of 60-90 seconds using the bipolar soft coagulation mode at 8-10 watts with an effect of 8 was found to be the most feasible setting. Twelve patients(5 females, 7 males; mean age, 70 years) underwent 19 endoscopic RFA(range, 1-5) sessions. Deployment of RFA was successful in all patients. Systemic chemotherapy was administered in four patients. We observed biliary bleeding 4-6 wk after the intervention in three cases and two of these patients died: in one patient, spontaneous hemobilia occurred, whereas bleeding started during stent extraction in the other. In the third patient, bleeding was stopped by insertion of a non-covered self-expanding metal stent. Another three patients developed cholangitis during follow-up. Seven patients died during follow-up and median survival was 6.4 mo(95%CI: 0.05-12.7) from the time of the first RFA. CONCLUSION: Endoscopic RFA is an easy to perform and technically highly successful procedure. However, hemobilia possibly associated with RFA occurred in three of our patients. Therefore, larger prospective studies are needed to further evaluate the safety and efficacy of this promising new method. | Andrea Oliver Tal Johannes Vermehren Mireen FriedrichRust Jrg Bojunga Christoph Sarrazin Stefan Zeuzem Jrg Trojan Jrg Gerhard Albert | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，1： | 18 |
| 2 | Transcutaneous perianal sonography:A sensitive method for the detection of perianal inflammatory lesions in Crohn's disease显示文摘AIM: Pelvic magnetic resonance imaging (MRI) and endoanalultrasound which are established imaging methods forperianal inflammatory lesions in patients with Crohn'sdisease require expensive specialized equipments andexpertise. We investigated the feasibility and sensitivity oftranscutaneous perianal ultrasound (PAUS) using regularultrasound probes in the imaging of perianal inflammatorylesions. The sonographic findings were correlated to pelvicMRI-scans.METHODS: We performed PAUS in 25 patients with Crohn'sdisease and clinical signs of perianal inflammatory disease.VCChin a median of 10 d (range 0-75) these patients underwentMRI of the pelvis. Regular convex and linear high resolutionprobes were used for PAUS. The sonographic findings werecorrelated to the MRI findings by blinded investigators.RESULTS: The sonographic investigations were welltolerated by all patients. Fistulae typically presented ashypoechoic tracks. Twenty-nine fistulae were detected in22 patients. Abscesses were detected in 7 patients andpresented as hypo- or anechoic formations. Twenty-six of29 fistulae and 6 of 7 abscesses could be confirmed byMRI. Kappa statistics showed an excellent agreement(kappa>0.83) between the two imaging methods.CONCLUSION: PAUS is a simple, painless, feasible, real-time method that can be performed without specific patientpreparation which is comparable in its sensitivity to pelvicMRI in the detection of perianal fistulae and/or abscesses.PAUS can especially be recommended as a screening toolin acute perianal disorders such as perianal abscess andfor follow-up studies of perianal inflammatory disease. | Jochen Wedemeyer Timm Kirchhoff Gernot Sellge Oliver Bachmann Joachim Lotz Michael Galanski Michael P.Manns Michael J.Gebel Jrg S.Bleck | 2004 | World Journal of Gastroenterology2004，10，19： | 8 |
| 3 | Quality of life:A critical outcome for all surgical treatmentsof gastric cancer显示文摘Surgery represents the main curative therapeutic modality for gastric cancer, and it is occasionally considered for palliation as well as prophylaxis. Most frequently, surgical outcomes are conveyed in terms of oncological outcomes such as recurrence and survival.However, quality of life(Qo L) is also important and should be considered when making treatment decisions- including the extent of and approach to surgery. Measurement of Qo L usually involves the application of questionnaires. While there are multiple Qo L questionnaires validated for use in oncology patients, there are very few that have been validated for use in those with gastric cancer. In this review, we discuss and compare the current status of Qo L questionnaires in gastric cancer. More importantly, the impact of surgery for treatment, palliation and prophylaxis of gastric cancer on Qo L will be described. These data should inform the surgeon on the optimal approach to treating gastric cancer, taking into account oncological outcomes. Knowledge gaps are also identified, providing a roadmap for future studies. | Michael D McCall Peter J Graham Oliver F Bathe | 2016 | World Journal of Gastroenterology2016，22，3： | 7 |
| 4 | SEMS vs cSEMS in duodenal and small bowel obstruction:High risk of migration in the covered stent group显示文摘AIM:To compare clinical success and complications of uncovered self-expanding metal stents(SEMS)vs covered SEMS(cSEMS)in obstruction of the small bowel.METHODS:Technical success,complications and outcome of endoscopic SEMS or cSEMS placement in tumor related obstruction of the duodenum or jejunum were retrospectively assessed.The primary end points were rates of stent migration and overgrowth.Secondary end points were the effect of concomitant biliary drainage on migration rate and overall survival.The data was analyzed according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.RESULTS:Thirty-two SEMS were implanted in 20 patients.In all patients,endoscopic stent implantation was successful.Stent migration was observed in 9 of16 cSEMS(56%)in comparison to 0/16 SEMS(0%)implantations(P=0.002).Stent overgrowth did not significantly differ between the two stent types(SEMS:3/16,19%;cSEMS:2/16,13%).One cSEMS dislodged and had to be recovered from the jejunum by way of laparotomy.Time until migration between SEMS and cSEMS in patients with and without concomitant biliary stents did not significantly differ(HR=1.530,95%CI0.731-6.306;P=0.556).The mean follow-up was 57±71 d(range:1-275 d).CONCLUSION:SEMS and cSEMS placement is safe in small bowel tumor obstruction.However,cSEMS is accompanied with a high rate of migration in comparison to uncovered SEMS. | Oliver Waidmann Jrg Trojan Mireen Friedrich-Rust Christoph Sarrazin Wolf Otto Bechstein Frank Ulrich Stefan Zeuzem Jrg Gerhard Albert | 2013 | World Journal of Gastroenterology2013，19，37： | 4 |
| 5 | Chronic intestinal failure and short bowel syndrome in Crohn’s disease显示文摘Chronic intestinal failure(CIF)is a rare but feared complication of Crohn’s disease.Depending on the remaining length of the small intestine,the affected intestinal segment,and the residual bowel function,CIF can result in a wide spectrum of symptoms,from single micronutrient malabsorption to complete intestinal failure.Management of CIF has improved significantly in recent years.Advances in home-based parenteral nutrition,in particular,have translated into increased survival and improved quality of life.Nevertheless,60%of patients are permanently reliant on parenteral nutrition.Encouraging results with new drugs such as teduglutide have added a new dimension to CIF therapy.The outcomes of patients with CIF could be greatly improved by more effective prevention,understanding,and treatment.In complex cases,the care of patients with CIF requires a multidisciplinary approach involving not only physicians but also dietitians and nurses to provide optimal intestinal rehabilitation,nutritional support,and an improved quality of life.Here,we summarize current literature on CIF and short bowel syndrome,encompassing epidemiology,pathophysiology,and advances in surgical and medical management,and elucidate advances in the understanding and therapy of CIF-related complications such as catheter-related bloodstream infections and intestinal failure-associated liver disease. | Aysegül Aksan Karima Farrag Irina Blumenstein Oliver Schröder Axel U Dignass Jürgen Stein | 2021 | World Journal of Gastroenterology2021，27，24： | 4 |
| 6 | Upper gastrointestinal bleeding in Scotland 2000-2010: Improved outcomes but a significant weekend effect显示文摘AIM: To assess numbers and case fatality of patients with upper gastrointestinal bleeding(UGIB),effects of deprivation and whether weekend presentation affected outcomes.METHODS: Data was obtained from Information Services Division(ISD) Scotland and National Records of Scotland(NRS) death records for a ten year period between 2000-2001 and 2009-2010. We obtained data from the ISD Scottish Morbidity Records(SMR01) database which holds data on inpatient and daycase hospital discharges from non-obstetric and nonpsychiatric hospitals in Scotland. The mortality data was obtained from NRS and linked with the ISD SMR01 database to obtain 30-d case fatality. We used 23 ICD-10(International Classification of diseases) codes which identify UGIB to interrogate database. We analysed these data for trends in number of hospital admissions with UGIB,30-d mortality over time and assessed effects of social deprivation. We compared weekend and weekday admissions for differences in 30-d mortality and length of hospital stay. We determined comorbidities for each admission to establish if comorbidities contributed to patient outcome. RESULTS: A total of 60643 Scottish residents were admitted with UGIH during January,2000 and October,2009. There was no significant change in annual number of admissions over time,but there was a statistically significant reduction in 30-d case fatality from 10.3% to 8.8%(P < 0.001) over these 10 years. Number of admissions with UGIB was higher for the patients from most deprived category(P < 0.05),although case fatality was higher for the patients from the least deprived category(P < 0.05). There was no statistically significant change in this trend between 2000/01-2009/10. Patients admitted with UGIB at weekends had higher 30-d case fatality compared with those admitted on weekdays(P < 0.001). Thirty day mortality remained significantly higher for patients admitted with UGIB at weekends after adjusting for comorbidities. Length of hospital stay was also higher overall for patients admitted at the weekend when compared to weekdays,although only reached statistical significance for the last year of study 2009/10(P < 0.0005). CONCLUSION: Despite reduction in mortality for UGIB in Scotland during 2000-2010,weekend admissions show a consistently higher mortality and greater lengths of stay compared with weekdays. | Asma Ahmed Matthew Armstrong Ishbel Robertson Allan John Morris Oliver Blatchford Adrian J Stanley | 2015 | World Journal of Gastroenterology2015，21，38： | 4 |
| 7 | Increased catabolism and decreased unsaturation of ganglioside in patients with inflammatory bowel disease显示文摘AIM: To investigate whether accelerated catabolism of ganglioside and decreased ganglioside content contribute to the etiology of pro-inflammatory intestinal disease. METHODS: Intestinal mucosa from terminal ileum or colon was obtained from patients with ulcerative colitis or inflammatory Crohn's disease(n = 11) undergoing bowel resection and compared to control samples of normal intestine from patients with benign colon polyps(n = 6) and colorectal cancer(n = 12) in this observational case-control study. Gangliosides and phospholipids of intestinal mucosa were characterized by class and ceramide or fatty acid composition using liquid chromatography triple-quad mass spectrometry. Content and composition of ganglioside classes GM1, GM3, GD3, GD1 a, GT1 and GT3 were compared among subject groups. Content and composition of phospholipid classes phosphatidylcholine(PC) and phosphatidylethanolamine were compared among subject groups. Unsaturation index of individual ganglioside and phospholipid classes was computed and compared among subject groups. Ganglioside catabolism enzymes beta-hexosaminidase A(HEXA) and sialidase-3(NEU3) were measured in intestinal mucosa using western blot and compared among subject groups. RESULTS: Relative GM3 ganglioside content was 2-fold higher(P < 0.05) in intestine from patients with inflammatory bowel disease(IBD) compared to control intestine. The quantity of GM3 and ratio of GM3/GD3 was also higher in IBD intestine than control tissue(P < 0.05). Control intestine exhibited 3-fold higher(P < 0.01) relative GD1 a ganglioside content than IBD intestine. GD3 and GD1 a species of ganglioside containing three unsaturated bonds were present in control intestine, but were not detected in IBD intestine. The relative content of PC containing more than two unsaturated bonds was 30% lower in IBD intestine than control intestine(P < 0.05). The relative content of HEXA in IBD intestine was increased 1.7-fold(P < 0.05) and NEU3 was increased 8.3-fold(P < 0.01) compared to normal intestine. Intestinal mucosa in IBD is characterized by increased GM3 content, decreased GD1 a, and a reduction in polyunsaturated fatty acid constituents in GD3, GD1 a and PC.CONCLUSION: This study suggests a new paradigm by proposing that IBD occurs as a consequence of increased metabolism of specific gangliosides. | John J Miklavcic Glen K Shoemaker Vera C Mazurak M Tom Clandinin Tasha DL Hart Kareena L Schnabl Gordon M Lees Bodil MK Larsen Oliver F Bathe Alan BR Thomson M Tom Clandinin | 2015 | World Journal of Gastroenterology2015，21，35： | 3 |
| 8 | Complicated fecal microbiota transplantation in a tetraplegic patient with severe Clostridium difficile infection显示文摘A 65-year-old male suffering from acute spinal cord injury leading to incomplete tetraplegia presented with severe recurrent Clostridium difficile(C. difficile) infection subsequent to antibiotic treatment for pneumonia. After a history of ineffective antimicrobial therapies, including metronidazole, vancomycin, fidaxomicin, rifaximin and tigecycline, leading to several relapses, the patient underwent colonoscopic fecal microbiota transplantation from his healthy son. Four days subsequent to the procedure, the patient showed a systemic inflammation response syndrome. Without detecting an infectious cause, the patient received antimicrobial treatment, including tigecycline, metronidazole, vancomycin via polyethylene glycol and an additional enema for a period of seven days, leading to a prompt recovery and no reported C. difficile infection relapse during a 12 wk follow up. | Thorsten Brechmann Justyna Swol Veronika Knop-Hammad Jrg Willert Mirko Aach Oliver Cruciger Wolff Schmiegel Thomas A Schildhauer Uwe Hamsen | 2015 | World Journal of Gastroenterology2015，21，12： | 3 |

| 17 | Genetic and environmental control of fruit maturation,dry matter and firmness in apple(Malus×domestica Borkh.)显示文摘For any given genotype,the environment in which an apple is grown can influence the properties of the fruit considerably.While there has been extensive research on the mechanism of the genetic control of fruit quality traits,less effort has been made to investigate the way that these genetic mechanisms interact with the environment.To address this issue,we employed a large‘Royal Gala’בBraeburn’population of 572 seedlings replicated over sites in three climatically diverse apple-growing regions in New Zealand.Phenotyping for traits including fruit maturation timing,firmness and dry matter content was performed at each of these three sites for a single growing season(2011),and at two sites(Motueka and Hawke’s Bay)for two seasons(2009 and 2010).The phenotype data collected over 2 years at two sites enabled the detection of 190 quantitative trait loci(QTL)that controlled these traits regardless of year or growing location,as well as some chromosomal loci that influenced the traits in a single given environment or year.For those loci that were environmentally stable over three sites,there was an interdependency of fruit maturation date,dry matter content and storage potential within this population,with two regions on Linkage Groups(LGs)10 and 16 strongly contributing.If these loci were used in a marker-assisted selection programme to select for progeny bearing firmer fruit,this would have the unintentional consequence of selecting,high dry matter content,later maturing apples.In addition,a further 113 new QTLs with a smaller effect were identified,some of which were exhibited only in a single growing environment,demonstrating the underlying complexity of control of traits determining fruit quality,in addition to the need for being aware of environmental effects when developing new apple varieties. | David Chagne Daya Dayatilake Robert Diack Murray Oliver Hilary Ireland Amy Watson Susan E Gardiner Jason W Johnston Robert J Schaffer Stuart Tustin | 2014 | Horticulture Research2014，1，1： | 2 |
