| 1 | Endoscopic treatment of duodenal fistula after incomplete closure of ERCP-related duodenal perforation显示文摘Endoscopic retrograde cholangiopancreatography(ERCP)is an important diagnostic and therapeutic modality for various pancreatic and biliary diseases.The most common ERCP-induced complication is pancreatitis,whereas hemorrhage,cholangitis,and perforation occur less frequently.Early recognition and prompt treatment of these complications may minimize the morbidity and mortality.One of the most serious complications is perforation.Although the incidence of duodenal perforation after ERCP has decreased to<1.0%,severe cases still require prolonged hospitalization and urgent surgical intervention,potentially leading to permanent disability or mortality.Surgery remains the mainstay treatment for perforations of the luminal organs of the gastrointestinal tract.However,evidence from case reports and case series support a beneficial role of endoscopic clipping in the closure of these defects.Duodenal fistulas are usually a result of sphincterotomies,perforated duodenal ulcers,or gastrectomy.Other causative factors include Crohn's disease,trauma,pancreatitis,and cancer.The majority of duodenal fistulas heal with nonoperative management.Those that fail to heal are best treated with gastrojejunostomy.Recently proposed endoscopic approaches for managing gastrointestinal leaks caused by fistulas include fibrin glue injection and positioning of endoclips.Our patient developed a secondary persistent duodenal fistula as a result of previous incomplete closure of duodenal perforation with hemoclips and an endoloop.The fistula was successfully repaired by additional clipping and fibrin glue injection. | Dong Wook Yu Man Yong Hong Seung Goun Hong | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，6： | 10 |
| 2 | Periodontitis combined with smoking increases risk of the ulcerative colitis: A national cohort study显示文摘BACKGROUND Periodontitis is a chronic inflammation of periodontal tissues.The effect of periodontitis on the development of inflammatory bowel disease(IBD)remains unclear.AIM To assessed the risk of IBD among patients with periodontitis,and the risk factors for IBD related to periodontitis.METHODS A nationwide population-based cohort study was performed using claims data from the Korean National Healthcare Insurance Service.In total,9950548 individuals aged≥20 years who underwent national health screening in 2009 were included.Newly diagnosed IBD[Crohn’s disease(CD),ulcerative colitis(UC)]using the International Classification of Disease 10th revision and rare intractable disease codes,was compared between the periodontitis and nonperiodontitis groups until 2017.RESULTS A total of 1092825 individuals(11.0%)had periodontitis.Periodontitis was significantly associated with older age,male gender,higher body mass index,quitting smoking,not drinking alcohol,and regular exercise.The mean age was 51.4±12.9 years in the periodontitis group and 46.6±14.2 years in the nonperiodontitis group(P<0.01),respectively.The mean body mass index was 23.9±3.1 and 23.7±3.2 in the periodontitis and non-periodontitis groups,respectively(P<0.01).Men were 604307(55.3%)and 4844383(54.7%)in the periodontitis and non-periodontitis groups,respectively.The mean follow-up duration was 7.26 years.Individuals with periodontitis had a significantly higher risk of UC than those without periodontitis[adjusted hazard ratio:1.091;95%confidence interval(CI):1.008-1.182],but not CD(adjusted hazard ratio:0.879;95%confidence interval:0.731-1.057).The risks for UC were significant in the subgroups of age≥65 years,male gender,alcohol drinker,current smoker,and reduced physical activity.Current smokers aged≥65 years with periodontitis were at a 1.9-fold increased risk of UC than non-smokers aged≥65 years without periodontitis.CONCLUSION Periodontitis was significantly associated with the risk of developing UC,but not CD,particularly in current smokers aged≥65 years. | Eun Ae Kang Jaeyoung Chun Jee Hyun Kim Kyungdo Han Hosim Soh Seona Park Seung Wook Hong Jung Min Moon Jooyoung Lee Hyun Jung Lee Jun-Beom Park Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020，26，37： | 3 |
| 3 | Trends and risk factors of elderly-onset Crohn’s disease: A nationwide cohort study显示文摘BACKGROUND The incidence of inflammatory bowel disease(IBD)is increasing in Asia.Numerous risk factors associated with IBD development have been investigated.AIM To investigate trends and environmental risk factors of Crohn’s disease(CD)diagnosed in persons aged≥40 years in South Korea.METHODS Using the National Health Insurance Service database,a total of 14060821 persons aged>40 years who underwent national health screening in 2009 were followed up until December 2017.Patients with newly diagnosed CD were enrolled and compared with non-CD cohort.CD was identified according to the International Classification of Diseases 10th revision and the rare/intractable disease registration program codes from the National Health Insurance Service database.The mean follow-up periods was 7.39 years.Age,sex,diabetes,hypertension,smoking,alcohol consumption,regular exercise,body mass index,anemia,chronic kidney disease(CKD)and dyslipidemia were adjusted for in the multivariate analysis model.RESULTS During the follow-up,1337(1.33/100000)patients developed CD.Men in the middle-aged group(40-64 years)had a higher risk than women[adjusted hazard ratio(aHR)1.46,95%confidence interval(CI):1.29-1.66];however,this difference tended to disappear as the age of onset increases.In the middle-aged group,patients with a history of smoking[(aHR 1.46,95%CI:1.19-1.79)and anemia(aHR 1.85,95%CI:1.55-2.20)]had a significantly higher CD risk.In the elderly group(age,≥65 years),ex-smoking and anemia also increased the CD risk(aHR 1.68,95%CI:1.22-2.30)and 1.84(95%CI:1.47-2.30,respectively).Especially in the middle-aged group,those with CKD had a statistically elevated CD risk(aHR 1.37,95%CI:1.05-1.79).Alcohol consumption and higher body mass index showed negative association trend with CD incidence in both of the age groups.[Middle-aged:aHR 0.77(95%CI:0.66-0.89)and aHR 0.73(95% CI:0.63-0.84),respectively][Elderly-group:aHR 0.57(95% CI:0.42-0.78)and aHR 0.84(95%CI 0.67-1.04),respectively].For regular physical activity and dyslipidemia,negative correlation between CD incidences was proved only in the middle-aged group[aHR 0.88(95%CI:0.77-0.89)and aHR 0.81(95%CI:0.68-0.96),respectively].CONCLUSION History of cigarette smoking,anemia,underweight and CKD are possible risk factors for CD in Asians aged>40 years. | Jung Min Moon Eun Ae Kang Kyungdo Han Seung Wook Hong Hosim Soh Seona Park Jooyoung Lee Hyun Jung Lee Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020，26，4： | 2 |
| 4 | Risk factors and prognostic value of acute severe lower gastrointestinal bleeding in Crohn’s disease显示文摘BACKGROUND Acute severe lower gastrointestinal bleeding(LGIB)is an uncommon but challenging complication of Crohn’s disease(CD).AIM To identify the predictors of acute severe LGIB and to evaluate the impact of acute severe LGIB on the subsequent clinical course in CD patients.METHODS A retrospective inception cohort study was conducted in 75 CD patients with acute severe LGIB and 1359 CD patients without acute severe LGIB who were diagnosed between February 1991 and November 2019 at Asan Medical Center,a tertiary university hospital in Korea.Multivariable analysis with Cox proportional hazard regression was performed to identify the risk factors for acute severe LGIB.A matched analysis using 72 patients with bleeding and 267 matched patients without within the cohort was also conducted to investigate whether acute severe LGIB is a predictor of clinical outcomes of CD.RESULTS Multivariable Cox regression analysis revealed that early use of thiopurines[hazard ratio(HR):0.23,95%confidence interval(CI):0.12-0.48;P<0.001]and female sex(HR:0.51,95%CI:0.27-0.94;P=0.031)were significantly associated with a lower risk of acute severe LGIB.The cumulative risks of behavioral progression and intestinal resection were not significantly different between the two matched groups(P=0.139 and P=0.769,respectively).The hospitalization rate was higher in the bleeding group than in the matched non-bleeding group(22.1/100 vs 13.2/100 patient-years;P=0.012).However,if hospitalizations due to bleeding episodes were excluded from the analysis,the hospitalization rate was not significantly different between the bleeding group and the matched nonbleeding group(14.5/100 vs 13.2/100 patient-years;P=0.631).CONCLUSION Early use of thiopurines may reduce the risk of acute severe LGIB.History of acute severe LGIB may not have a significant prognostic value in patients with CD. | Jiyoung Yoon Dae Sung Kim Ye-Jee Kim Jin Wook Lee Seung Wook Hong Ha Won Hwang Sung Wook Hwang Sang Hyoung Park Dong-Hoon Yang Byong Duk Ye Jeong-Sik Byeon Seung-Jae Myung Suk-Kyun Yang | 2021 | World Journal of Gastroenterology2021，27，19： | 1 |
