| 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 |

| 3 | Influence of antibiotic-regimens on intensive-care unit-mortality and liver-cirrhosis as risk factor显示文摘AIM: To assess the rate of infection, appropriateness of antimicrobial-therapy and mortality on intensive care unit(ICU). Special focus was drawn on patients with liver cirrhosis.METHODS: The study was approved by the local ethical committee. All patients admitted to the Internal Medicine-ICU between April 1, 2007 and December 31, 2009 were included. Data were extracted retrospectively from all patients using patient charts and electronic documentations on infection, microbiological laboratory reports, diagnosis and therapy. Due to the large hepatology department and liver transplantation center, special interest was on the subgroup of patients with liver cirrhosis. The primary statistical-endpoint was the evaluation of the influence of appropriate versusinappropriate antimicrobial-therapy on in-hospitalmortality.RESULTS: Charts of 1979 patients were available. The overall infection-rate was 53%. Multiresistantbacteria were present in 23% of patients with infection and were associated with increased mortality(p < 0.000001). patients with infection had significantly increased in-hospital-mortality(34% vs 17%, p < 0.000001). Only 9% of patients with infection received inappropriate initial antimicrobial-therapy, no influence on mortality was observed. Independent risk-factors for in-hospital-mortality were the presence of septicshock, prior chemotherapy for malignoma and infection with pseudomonas spp. Infection and mortality-rate among 175 patients with liver-cirrhosis was significantly higher than in patients without liver-cirrhosis. Infection increased mortality 2.24-fold in patients with cirrhosis. patients with liver cirrhosis were at an increased risk to receive inappropriate initial antimicrobial therapy.CONCLUSION: The results of the present study report the successful implementation of early-goal-directed therapy. Liver cirrhosis patients are at increased risk of infection, mortality and to receive inappropriate therapy. Increasing burden are multiresistant-bacteria. | Mireen Friedrich-Rust Beate Wanger Florian Heupel Natalie Filmann Reinhard Brodt Volkhard AJ Kempf Johanna Kessel Thomas A Wichelhaus Eva Herrmann Stefan Zeuzem Joerg Bojunga | 2016 | World Journal of Gastroenterology2016，22，16： | 6 |
| 4 | Liver elastography, comments on EFSUMB elastography guidelines 2013显示文摘Recently the European Federation of Societies for Ultrasound in Medicine and Biology Guidelines and Recommendations have been published assessing the clinical use of ultrasound elastography.The document is intended to form a reference and to guide clinical users in a practical way.They give practical advice for the use and interpretation.Liver disease forms the largest section,reflecting published experience to date including evidence from meta-analyses with shear wave and strain elastography.In this review comments and illustrations on the guidelines are given. | Xin-Wu Cui Mireen Friedrich-Rust Chiara De Molo Andre Ignee Dagmar Schreiber-Dietrich Christoph F Dietrich | 2013 | World Journal of Gastroenterology2013，19，38： | 4 |
| 5 | 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 |
| 6 | FibroSURE^(TM) and FibroScan~ in relation to treatment response in chronic hepatitis C virus显示文摘AIM:To compare histological endpoint assessment using noninvasive alternatives to biopsy during treatment in a chronic hepatitis C virus(HCV)cohort.METHODS:Patients with chronic HCV were randomized to receive interferon-based therapy for 24(genotypes 2/3)or 48(genotype 1)wk.FibroSURE~TM(FS)was assessed at baseline and at week-12 post-treatment follow-up.Baseline biopsy for METAVIR was assessed by a single pathologist.FibroScan~ transient elastogra-phy(TE)was performed during treatment in a patient subset.RESULTS:Two thousand and sixty patients(n = 253 in Asia)were classif ied as METAVIR F0-1(n = 1682)or F2-4(n = 378).For F2-4,FS(n = 2055)had sensitiv-ity and specif icity of 0.87 and 0.61,respectively,with area under the receiver-operating curve of 0.82;corre-sponding values for TE(n = 214)and combined FS/TE(n = 209)were 0.77,0.88 and 0.88,and 0.93,0.68 and 0.88.Overall FS/TE agreement for F2-4 was 71%(κ = 0.41)and higher in Asians vs non-Asians(κ = 0.86 vs 0.35;P < 0.001).Combined FS/TE had 97% accuracy in Asians(n = 33).Baseline FS(0.38 vs 0.51,P < 0.001)and TE(8.0 kPa vs 11.9 kPa,P = 0.006)scores were lower in patients with sustained virological response than in nonresponders,and were maintained through follow-up.CONCLUSION:FS and TE may reliably differentiate mild from moderate-advanced disease,with a potential for high diagnostic accuracy in Asians with chronic HCV. | Keyur Patel Mireen Friedrich-Rust Yoav Lurie Mircea Grigorescu Carol Stanciu Chuan-Mo Lee Eugene R Schiff Dieter Hussinger Michael P Manns Guido Gerken Isabelle Colle Michael Torbenson Erik Pulkstenis G Mani Subramanian John G McHutchison Stefan Zeuzem | 2011 | World Journal of Gastroenterology2011，17，41： | 4 |
