| 1 | Severe acute pancreatitis: Clinical course and management显示文摘Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis (AP). Severity of AP is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis pathomorphologically. Risk factors determining independently the outcome of SAP are early multi-organ failure, infection of necrosis and extended necrosis (> 50%). Up to one third of patients with necrotizing pancreatitis develop in the late course infection of necroses. Morbidity of SAP is biphasic, in the first week strongly related to early and persistence of organ or multi-organ dysfunction. Clinical sepsis caused by infected necrosis leading to multi-organ failure syndrome (MOFS) occurs in the later course after the first week. To predict sepsis, MOFS or deaths in the first 48-72 h, the highest predictive accuracy has been objectified for procalcitonin and IL-8; the Sepsis- Related Organ Failure Assessment (SOFA)-score predicts the outcome in the first 48 h, and provides a daily assessment of treatment response with a high positive predictive value. Contrast-enhanced CT provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or at risk of developing a severe disease require early intensive care treatment. Early vigorous intravenous fluid replacement is of foremost importance. The goal is to decrease the hematocrit or restore normal cardiocirculatory functions. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis, pancreatic abscess or surgical acute abdomen are candidates for early intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased in high volume centers to below 20%. | Hans G Beger Bettina M Rau | 2007 | World Journal of Gastroenterology2007，13，38： | 122 |
| 2 | Split liver transplantation: Current developments显示文摘In 1988, Rudolf Pichlmayr pioneered split liver transplantation(SLT), enabling the transplantation of one donor liver into two recipients-one pediatric and one adult patient. In the same year, Henri Bismuth and colleagues performed the first full right/full left split procedure with two adult recipients. Both splitting techniques were rapidly adopted within the transplant community. However, a SLT is technically demanding, may cause increased perioperative complications, and may potentially transform an excellent deceased donor organ into two marginal quality grafts. Thus, crucial evaluation of donor organs suitable for splitting and careful screening of potential SLT recipients is warranted. Furthermore, the logistic background of the splitting procedure as well as the organ allocation policy must be adapted to further increase the number and the safety of SLT. Under defined circumstances, in selected patients and at experienced transplant centers, SLT outcomes can be similar to those obtained in full organ LT. Thus, SLT is an important tool to reduce the donor organ shortage and waitlist mortality, especially for pediatric patients and small adults. The present review gives an overview of technical aspects, current developments, and clinical outcomes of SLT. | Christina Hackl Katharina M Schmidt Caner Süsal Bernd Dohler Martin Zidek Hans J Schlitt | 2018 | World Journal of Gastroenterology2018，24，47： | 20 |
| 3 | In vitro activity of moxifloxacin and piperacillin/sulbactam against pathogens of acute cholangitis显示文摘AIM: To analyze the in vitro activity of moxifloxacin and piperacillin/sulbactam against pathogens isolated from patients with acute cholangitis. METHODS: In this prospective study a total of 65 patients with acute cholangitis due to biliary stone obstruction (n = 7), benign biliary stricture (n = 16), and malignant biliary stricture (n = 42) were investigated with regard to spectrum of bacterial infection and antibiotic resistance. Pathogens were isolated from bile cultures in all study patients. In 22 febrile patients, blood cultures were also obtained. In vitro activity of moxifloxacin and piperacillin/ sulbactam was determined by agar diffusion. RESULTS: Thirty-one out of 65 patients had positive bile and/or blood cultures. In 31 patients, 63 isolates with 17 different species were identified. The predominant strains were Enterococcus species (26/63), E.coli (13/63) and Klebsiella species (8/63). A comparable in vitro activity of moxifloxacin and piperacillin/sulbactam was observed for E.coli and Klebsiella species. In contrast, Enterococcus species had higher resistances towards moxifloxacin. Overall bacteria showed antibiotic resistances in vitro of 34.9% for piperacillin/sulbactam and 36.5% for moxifloxacin.CONCLUSION: Enterococcus species , E.coli and Klebsiella species were the most common bacteria isolated from bile and/or blood from patients with acute cholangitis. Overall, a mixed infection with several species was observed, and bacteria showed a comparable in vitro activity for piperacillin/sulbactam and moxifloxacin. | Andreas Weber Wolfgang Huber Klaus Kamereck Philipp Winkle Petra Voland Hans Weidenbach Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，20： | 18 |
| 4 | Endoscopic transpapillary brush cytology and forceps biopsy in patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the sensitivity of brush cytology and forceps biopsy in a homogeneous patient group with hilar cholangiocarcinoma.METHODS: Brush cytology and forceps biopsy were routinely performed in patients with suspected malignant biliary strictures. Fifty-eight consecutive patients undergoing endoscopic retrograde cholangio-pancreatography (ERCP) including forceps biopsy and brush cytology in patients with hilar cholangiocarcinoma between 1995-2005.RESULTS: Positive results for malignancy were obtained in 24/58 patients (41.4%) by brush cytology and in 31/58 patients (53.4%) by forceps biopsy. The combination of both techniques brush cytology and forceps biopsy resulted only in a minor increase in diagnostic sensitivity to 60.3% (35/58 patients). In 20/58 patients (34.5%), diagnosis were obtained by both positive cytology and positive histology, in 11/58 (19%) by positive histology (negative cytology) and only 4/58 patients (6.9%) were confirmed by positive cytology (negative histology).CONCLUSION: Brush cytology and forceps biopsy have only limited sensitivity for the diagnosis of malignant hilar tumors. In our eyes, additional diagnostic techniques should be evaluated and should become routine in patients with negative cytological and histological findings. | Andreas Weber Claus von Weyhern Falko Fend Jochen Schneider Bruno Neu Alexander Meining Hans Weidenbach Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，7： | 17 |
| 5 | Clinically detected gastroenteropancreatic neuroendocrine tumors are on the rise: Epidemiological changes in Germany显示文摘AIM:To study the epidemiologic changes of gastroenteropancreatic neuroendocrine tumors(GEP-NET)in Germany,we analyzed two time periods 1976-1988 and1998-2006.METHODS:We evaluated epidemiological data of GEP-NET from the former East German National Cancer Registry(DDR Krebsregister,1976-1988)and its successor,the Joint Cancer Registry(GKR,1998-2006),which was founded after German reunification.Due to a particularly substantial database the epidemiological data from the federal states of Mecklenburg-Western Pomerania,Saxony,Brandenburg and Thuringia,covering a population of more than 10.8 million people,were analyzed.Survival probabilities were calculated using life table analysis.In addition,GEP-NET patients were evaluated for one or more second(non-GEP-NET)primary malignancies.RESULTS:A total of 2821 GEP neuroendocrine neoplasms were identified in the two registries.The overall incidence increased significantly between 1976 and2006 from 0.31(per 100.000 inhabitants per year)to2.27 for men and from 0.57 to 2.38 for women.In the later period studied(2004-2006),the small intestine was the most common site.Neuroendocrine(NE)neoplasms of the small intestine showed the largest absolute increase in incidence,while rectal NE neoplasms exhibited the greatest relative increase.Only the incidence of appendiceal NET in women showed little change between 1976 and 2006.Overall survival of patients varied for sex,tumor site and the two periods studied but improved significantly over time.Interestingly,about 20%of the GEP-NET patients developed one or more second malignancies.Their most common location was the gastrointestinal tract.GEP-NET patients without second malignancies fared better than those with one or more of them.CONCLUSION:The number of detected GEP-NET increased about 5-fold in Germany between 1976 and2006.At the same time,their anatomic distribution changed,and the survival of GEP-NET patients improved significantly.Second malignancies are common and influence the overall survival of GEP-NET patients.Thus,GEP-NET warrant our attention as well as intensive research on their tumorigenesis. | Hans Scherübl Brigitte Streller Roland Stabenow Hermann Herbst Michael Hopfner Christoph Schwertner Joachim Steinberg Jan Eick Wanda Ring Krishna Tiwari Soren M Zappe | 2013 | World Journal of Gastroenterology2013，19，47： | 16 |

| 7 | Clostridium difficile causing acute renal failure: Case presentation and review显示文摘AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications. | Jasmin Arrich Gottfried H.Sodeck Gürkan Seng(o|¨)lge Christoforos Konnaris Marcus Müllner Anton N.Laggner Hans Domanovits | 2005 | World Journal of Gastroenterology2005，11，8： | 15 |

| 12 | Isolation and characterization of facultative mixotrophic ammonia-oxidizing bacteria from constructed wetlands显示文摘Autotrophic ammonia-oxidizing bacteria (AOB) have been widely studied in constructed wetlands systems,while mixotrophic AOB have been less thoroughly examined.Heterotrophic bacteria were isolated from wastewater and rhizospheres of macrophytes of constructed wetlands,and then cultivated in a mixotrophic medium containing ammonium and acetic acid.A molecular characterization was accomplished using ITS-PCR amplification,and phylogenetic analysis based on 16S rRNA gene sequences.Results showed the presence of 35 bacteria,among 400 initially heterotrophic isolates,that were able to remove ammonia.These 35 isolates were classified into 10 genetically different groups based on ITS pattern.Then,a collection of 10 isolates were selected because of their relatively high ammonia removal efficiencies (ARE 80%) and their phylogenetic diversity.In conditions of mixotrophy,these strains were shown to be able to grow (increase of optical density OD 660 during incubation with assimilation of nitrogen into cellular biomass) and to oxidize ammonia (important ammonia oxidation efficiencies,AOE between 79% and 87%).Among these facultative mixotrophic AOB,four isolates were genetically related to Firmicutes (Bacillus and Exiguobacterium),three isolates were affiliated to Actinobacteria (Arthrobacter) and three other isolates were associated with Proteobacteria (Pseudomonas,Ochrobactrum and Bordetella). | Soulwène Kouki Neila Saidi Fadhel M'hiri Houda Nasr Hanène Cherif Hadda Ouzari Abdennaceur Hassen | 2011 | Journal of Environmental Sciences2011，23，10： | 9 |

| 14 | Nitrite,a novel method to decrease ischemia/reperfusion injury in the rat liver显示文摘AIM:To investigate whether nitrite administered prior to ischemia/reperfusion(I/R)reduces liver injury.METHODS:Thirty-six male Sprague-Dawley rats were randomized to 3 groups,including sham operated(n=8),45-min segmental ischemia of the left liver lobe(IR,n=14)and ischemia/reperfusion(I/R)preceded by the administration of 480 nmol of nitrite(n=14).Serum transaminases were measured after 4 h of reperfusion.Liver microdialysate(MD)was sampled in 30-min intervals and analyzed for glucose,lactate,pyruvate and glycerol as well as the total nitrite and nitrate(NOx).The NOx was measured in serum.RESULTS:Aspartate aminotransferase(AST)at the end of reperfusion was higher in the IR group than in the nitrite group(40±6.8μkat/L vs 22±2.6μkat/L,P=0.022).Similarly,alanine aminotransferase(ALT)was also higher in the I/R group than in the nitrite group(34±6μkat vs 14±1.5μkat,P=0.0045).The NOx in MD was significantly higher in the nitrite group than in the I/R group(10.1±2.9μmol/L vs 3.2±0.9μmol/L,P=0.031)after the administration of nitrite.During ischemia,the levels decreased in both groups and then increased again during reperfusion.At the end of reperfusion,there was a tendency towards a higher NOx in the I/R group than in the nitrite group(11.6±0.7μmol/L vs 9.2±1.1μmol/L,P=0.067).Lactate in MD was significantly higher in the IR group than in the nitrite group(3.37±0.18 mmol/L vs 2.8±0.12 mmol/L,P=0.01)during ischemia and the first 30 min of reperfusion.During the same period,glycerol was also higher in the IRI group than in the nitrite group(464±38μmol/L vs 367±31μmol/L,P=0.049).With respect to histology,there were more signs of tissue damage in the I/R group than in the nitrite group,and29%of the animals in the I/R group exhibited necrosis compared with none in the nitrite group.Inducible nitric oxide synthase transcription increased between early ischemia(t=15)and the end of reperfusion in both groups.CONCLUSION:Nitrite administered before liver ischemia in the rat liver reduces anaerobic metabolism and cell necrosis,which could be important in the clinical setting. | Bergthor Bjrnsson Linda Bojmar Hans Olsson Tommy Sundqvist Per Sandstrm | 2015 | World Journal of Gastroenterology2015，21，6： | 8 |
| 15 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021，24，8： | 7 |
| 16 | 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 |

| 19 | Colonoscopic yield of colorectal neoplasia in daily clinical practice显示文摘AIM:To assess the prevalence and location of ad-vanced neoplasia in patients undergoing colonoscopy,and to compare the yield per indication.METHODS:In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland),data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm was defi ned as adenoma > 10 mm in size,with > 25% villous features or with high-grade dyspla-sia or cancer.RESULTS:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinomas and 342 (7%) advanced adenomas. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proximal colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a normal distal colon,whereas 27% had a syn-chronous distal adenoma. Ten percent of all colono-scopies were performed in asymptomatic patients,7% of whom had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from 11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both symptomatic and asymptomatic patients. | Jochim S Terhaar sive Droste Mike E Craanen Rene WM van der Hulst Joep F Bartelsman Dick P Bezemer Kim R Cappendijk Gerrit A Meijer Linde M Morsink Pleun Snel Hans ARE Tuynman Roy LJ van Wanrooy Eric IC Wesdorp Chris JJ Mulder | 2009 | World Journal of Gastroenterology2009，15，9： | 6 |
