1Endoscopic removal of gastric ectopic pancreas:An initial experience with endoscopic submucosal dissection显示文摘AIM:To evaluate the therapeutic usefulness and safety of endoscopic resection in patients with gastric ectopic pancreas.METHODS:A total of eight patients with ectopic pancreas were included.All of them underwent endoscopic ultrasonography before endoscopic resection.Endo-scopic resection was performed by two methods:endo-scopic mucosal resection(EMR)by the injection-and-cut technique or endoscopic mucosal dissection(ESD).RESULTS:We planned to perform EMR in all eight cases but EMR was successful in only four cases.In the other four cases,saline spread into surrounding normal tissues and the lesions becameattened,which made it impossible to remove them by EMR.Inthose four cases,we performed ESD and removed the lesions without any complications.CONCLUSION:If conventional EMR is difficult to remove gastric ectopic pancreas,ESD is a feasible alternative method for successful removal.Dong Yup Ryu Gwang Ha Kim Do Youn Park Bong Eun Lee Jae Hoon Cheong Dong Uk Kim Hyun Young Woo Jeong Heo Geun Am Song 2010World Journal of Gastroenterology2010,16,36:24
2美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病临床前阶段的定义显示文摘阿尔茨海默病(AD)的病理生理过程在痴呆诊断的多年前就开始了。这一长期的AD“临床前”阶段是治疗干预的关键机会,但需进一步阐明AD的病理级联过程和临床症状出现之间的联系。美国国立老化研究所和AD协会召集了一个国际工作组对AD生物标志物、流行病学和神经心理学的证据进行综述并提出建议,以确定能够预测由“正常”认知到轻度认知功能障碍(MCI)及AD痴呆的最佳预测指标。根据目前已有的主要科学证据,我们提出了一个概念性的框架和用于操作的研究标准,以通过纵向临床研究来验证和改进这些模型。这些建议仅用于研究目的,目前不涉及临床应用。我们希望这些建议能提供一个共识,以推进临床前AD的研究,最终推动更早期治疗干预的进展,使得一些疾病减缓药物的疗效发挥最大。Sperling RA Aisen PS Beckett LA Bennett DA Craft S Fagan AM Iwatsubo T Jack CR Jr Kaye J Montine TJ Park DC Reiman EM Rowe CC Siemers E Stern Y Yaffe K Carrillo MC Thies B Morrison-Bogorad M Wagster MV Phelps CH 贾建平(译) 郭起浩(译) 黄丽(译) 陆璐(译) 张逸驰(译) 邢怡(译) 2012中华神经科杂志2012,45,5:22
3Somatostatin adjunctive therapy for non-variceal upper gastrointestinal rebleeding after endoscopic therapy显示文摘AIM:To evaluate the effect of pantoprazole with a somatostatin adjunct in patients with acute non-variceal upper gastrointestinal bleeding(NVUGIB).METHODS:We performed a retrospective analysis of a prospective database in a tertiary care university hospital.From October 2006 to October 2008,we enrolled 101 patients with NVUGIB that had a high-risk stigma on endoscopy.Within 24 h of hospital admission,all patients underwent endoscopic therapy.After successful endoscopic hemostasis,all patients received an 80-mg bolus of pantoprazole followed by continuous intravenous infusion(8 mg/h for 72 h).The somatostatin adjunct group(n=49)also received a 250-μg bolus of somatostatin,followed by continuous infusion (250μg/h for 72 h).Early rebleeding rates,disappearance of endoscopic stigma and risk factors associated with early rebleeding were examined.RESULTS:Early rebleeding rates were not significantly different between treatment groups(12.2%vs 14.3%,P=0.766).Disappearance of endoscopic stigma on the second endoscopy was not significantly different between treatment groups(94.2%vs 95.9%,P=0.696).Multivariate analysis showed that the complete Rockall score was a significant risk factor for early rebleeding(P =0.044,OR:9.080,95%CI:1.062-77.595).CONCLUSION:The adjunctive use of somatostatin was not superior to pantoprazole monotherapy after successful endoscopic hemostasis in patients with NVUGIB.Cheol Woong Choi Dae Hwan Kang Hyung Wook Kim Su Bum Park Kee Tae Park Gwang Ha Kim Geun Am Song Mong Cho 2011World Journal of Gastroenterology2011,17,29:15
4Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS?显示文摘AIM: To evaluate the ultrasonog raphy (EUS) features of gastric gastrointestinal stromal tumors (GISTs) as compared with gastric leiomyomas and then to determine the EUS features that could predict malignant GISTs.METHODS: We evaluated the endoscopic EUS features in 53 patients with gastric mesenchymal tumors conf irmed by histopathologic diagnosis. The GISTs were classif ied into benign and malignant groups according to the histological risk classif ication.RESULTS: Immunohistochemical analyses demon-strated 7 leiomyomas and 46 GISTs. Inhomogenicity, hyperechogenic spots, a marginal halo and higher echogenicity as compared with the surrounding muscle layer appeared more frequently in the GISTs than in the leiomyomas (P < 0.05). The presence of at least two of these four features had a sensitivity of 89.1% and a specifi city of 85.7% for predicting GISTs. Except for tumor size and irregularity of the border, most of the EUS features were not helpful for predicting the malignant potential of GISTs. On multivariate analysis, only the maximal diameter of the GISTs was an independent predictor. The optimal size for predicting malignant GISTs was 35 mm. The sensitivity and specificity using this value were 92.3% and 78.8%, respectively.CONCLUSION: EUS may help to differentiate gastric GISTs from gastric leiomyomas. Once GISTs are suspected, surgery should be considered if the size is greater than 3.5 cm.Gwang Ha Kim Do Youn Park Suk Kim Dae Hwan Kim Dong Heon Kim Cheol Woong Choi Jeong Heo Geun Am Song 2009World Journal of Gastroenterology2009,15,27:12
5H pylori eradication:A randomized prospective study of triple therapy with or without ecabet sodium显示文摘AIM: To investigate whether adding ecabet sodium to the standard triple therapy for H pylori infection improve eradication rate. METHODS: Two hundred and fifty-seven H pylori-infected patients were randomly assigned to standard triple therapy (group A, n = 129) or triple therapy plus ecabet sodium (group B, n = 128). Successful eradication was defined as a negative 13C-urea breath test 6-8 wk after completion of treatment. RESULTS: After completion of therapy, 194/257 patients showed negative 13C-urea breath test results. According to intention-to-treat analysis, the infection was eradicated in 93/129 (72.1%) patients in group A and 101/128 (78.9%) in group B (P = 0.204). Per-protocol analysis showed successful eradication in 93/118 (78.8%) patients from group A and 101/114 (88.6%) from group B (P = 0.044). There were no significant differences in the side effects experienced by the patients in the two treatment groups. CONCLUSION: Our results suggest that the addition of ecabet sodium improves the efficacy of the standard triple therapy for H pylori.Hyung Wook Kim Gwang Ha Kim Jong Yun Cheong Ung Suk Yang Seung Keun Park Chul Soo Song Dae Hwan Kang Geun Am Song 2008World Journal of Gastroenterology2008,14,6:9
6Clinicopathologic factors influencing the accuracy of EUS for superficial esophageal carcinoma显示文摘AIM:To identify clinicopathologic factors influencing the accuracy of a high-frequency catheter probe endoscopic ultrasonography(EUS)for superficial esophageal carcinomas(SECs).METHODS:A total of 126 patients with endoscopically suspected SEC,who underwent EUS and curative treatment at Pusan National University Hospital during2005-2013,were enrolled.We reviewed the medical records of the 126 patients and compared EUS findings with histopathologic results according to clinicopathologic factors.RESULTS:A total of 114 lesions in 113 patients were included in the final analysis.The EUS assessment of tumor invasion depth was accurate in 78.9%(90/114)patients.Accuracy did not differ according to histologic type,tumor differentiation,tumor location,or macroscopic shape.However,accuracy significantly decreased for tumors≥3 cm in size(P=0.002).Overestimation and underestimation of the invasion depth occurred for 11(9.6%)and 13 lesions(11.4%),respectively.In multivariate analyses,tumor size≥3 cm was the only factor significantly associated with EUS accuracy(P=0.031),and was specifically associated with the underestimation of invasion depth.CONCLUSION:EUS using a high-frequency catheter probe generally provides highly accurate assessments of SEC invasion depth,but its accuracy decreases for tumors≥3 cm.Jung Im Jung Gwang Ha Kim Hoseok I Do Youn Park Tae Kyun Kim Young Hwa Cho Yong Wan Sung Mun Ki Choi Bong Eun Lee Geun Am Song 2014World Journal of Gastroenterology2014,20,20:9
7Risk of lymph node metastasis in mixed-type early gastric cancer determined by the extent of the poorly differentiated component显示文摘AIM: To predict the rate of lymph node(LN) metastasis in diffuse- and mixed-type early gastric cancers(EGC) for guidelines of the treatment.METHODS: We reviewed 550 cases of EGC withdiffuse- and mixed-type histology. We investigated the clinicopathological factors and histopathological components that influence the probability of LN metastasis, including sex, age, site, gross type, presence of ulceration, tumour size, depth of invasion, perineural invasion, lymphovascular invasion, and LN metastasis status. We reviewed all slides and estimated the proportions of each tumour component; pure diffuse type, mixed-predominantly diffuse type(diffuse > intestinal type), mixed-predominantly intestinal type(intestinal > diffuse type), and mixed diffuse = intestinal type. We calculated the extents of the respective components.RESULTS: LN metastasis was observed in 12.9%(71/550) of early gastric cancers cases [15/288 mucosal EGCs(5.2%) and 56/262 submucosal EGCs(21.4%)]. Of 550 cases, 302 were diffuse-type and 248 were mixed-type EGCs. Of 248 mixed-type EGCs, 163 were mixed-predominantly diffuse type, 82 were mixed-predominantly intestinal type, and 3 were mixed diffuse = intestinal type. Mixed-type cases with predominantly diffuse type histology showed a higher frequency of LN metastasis(20.2%) than cases of pure diffuse type(9.3%) and predominantly intestinal type(12.2%) histology. We measured the dimensions of each component(intestinal and diffuse type) to determine the association of the extent of each component with LN metastasis in mixed-type gastric carcinoma. The total tumour size and the extent of poorly differentiated components was associated with LN metastasis, while that of signet ring cell components was not.CONCLUSION: We recommend careful identification and quantitative evaluation of mixed-type early gastric cancer components after endoscopic resection to determine the intensity of the treatment.Chung-Su Hwang Sangjeong Ahn Bong-Eun Lee So-Jeong Lee Ahrong Kim Chang In Choi Dae Hwan Kim Tae-Yong Jeon Gwang Ha Kim Geum Am Song Do Youn Park 2016World Journal of Gastroenterology2016,22,15:8
8Associated factors for a hyperechogenic pancreas on endoscopic ultrasound显示文摘AIM: To identify the associated risk factors for hyperechogenic pancreas (HP) which may be observed on endoscopic ultrasound (EUS) and to assess the relationship between HP and obesity. METHODS: From January 2007 to December 2007, we prospectively enrolled 524 consecutive adults who were scheduled to undergo EUS. Patients with a history of pancreatic disease or with hepatobiliary or advanced gastrointestinal cancer were excluded. Finally,284 patients were included in the analyses. We further analyzed the risk of HP according to the categories of visceral adipose tissue (VAT) and subcutaneous adipose tissue in 132 patients who underwent abdominal computed tomography scans. RESULTS: On univariate analysis, age older than 60 years, obesity (body mass index > 25 kg/m 2 ), fatty liver, diabetes mellitus, hypertension and hypercholesterolemia were identified as risk factors associated with HP (P < 0.05). On multivariate analysis, fatty liver [P = 0.008, odds ratio (OR) = 2.219], male gender (P = 0.013, OR = 2.636), age older than 60 years (P = 0.001, OR = 2.874) and hypertension (P = 0.044, OR = 2.037) were significantly associated with HP. In the subgroup analysis, VAT was a statistically significant risk factor for HP (P = 0.010, OR = 5.665, lowest quartile vs highest quartile). CONCLUSION: HP observed on EUS was associated with fatty liver, male gender, age older than 60 years, hypertension and VAT.Cheol Woong Choi Gwang Ha Kim Dae Hwan Kang Hyung Wook Kim Dong Uk Kim Jeong Heo Geun Am Song Do Youn Park Suk Kim 2010World Journal of Gastroenterology2010,16,34:8

10Significant risk and associated factors of active tuberculosis infection in Korean patients with inflammatory bowel disease using anti-TNF agents显示文摘AIM:To evaluate the incidence and risk factors of Korean tuberculosis(TB) infection in patients with inflammatory bowel disease(IBD) undergoing anti-TNF treatment.METHODS:The data of IBD patients treated with anti-TNFs in 13 tertiary referral hospitals located in the southeastern region of Korea were collected retrospectively.They failed to show response or were intolerant to conventional treatments,including steroids or immunomodulators.Screening measures for latent TB infection(LTBI)and the incidence and risk factors ofactive TB infection after treatment with anti-TNFs were identified.RESULTS:Overall,376 IBD patients treated with antiTNF agents were recruited(male 255,mean age of anti-TNF therapy 32.5±13.0 years);277 had Crohn’s disease,99 had ulcerative colitis,294 used infliximab,and 82 used adalimumab.Before anti-TNF treatment,screening tests for LTBI including an interferon gamma release assay or a tuberculin skin test were performed in 82.2%of patients.Thirty patients(8%)had LTBI.Sixteen cases of active TB infection including one TB-related mortality occurred during 801 personyears(PY)follow-up(1997.4 cases per 100000 PY)after anti-TNF treatment.LTBI(OR=5.76,95%CI:1.57-21.20,P=0.008)and WBC count<5000 mm3(OR=4.5,95%CI:1.51-13.44,P=0.007)during follow-up were identified as independently associated risk factors.CONCLUSION:Anti-TNFs significantly increase the risk of TB infection in Korean patients with IBD.The considerable burden of TB and marked immunosuppression might be attributed to this risk.Eun Soo Kim Geun Am Song Kwang Bum Cho Kyung Sik Park Kyeong Ok Kim Byung Ik Jang Eun Young Kim Seong Woo Jeon Hyun Seok Lee Chang Heon Yang Yong Kook Lee Dong Wook Lee Sung Kook Kim Tae Oh Kim Jonghun Lee Hyung Wook Kim Sam Ryong Jee Seun Ja Park Hyun Jin Kim 2015World Journal of Gastroenterology2015,21,11:5
11Magnifying endoscopy of gastric epithelial dysplasia based on the morphologic characteristics显示文摘AIM:To investigate the difference in magnifying endoscopic findings of gastric epithelial dysplasias(GEDs)according to the morphologic characteristics.METHODS:This study included 46 GED lesions in 45patients who underwent magnifying endoscopy using narrow band imaging(ME-NBI)before endoscopic resection.During ME-NBI,the microvascular and microsurface(MS)patterns and the presence of light blue crest(LBC)and white opaque substance were investigated.GEDs were categorized as adenomatous,foveolar,and hybrid types,and their mucin phenotype was evaluated.RESULTS:Of the 46 lesions,27(59%)were categorized as adenomatous,15(32%)as hybrid,and the remaining 4(9%)as foveolar.All adenomatous GEDs showed the round pit and/or tubular MS patterns,all foveolar GEDs showed the papillary pattern,and hybrid GEDs showed mixed patterns(P<0.001).LBC was more frequently observed in adenomatous GEDs than in hybrid or foveolar GEDs(52%,33%,0%,respectively),although this difference was not significant(P=0.127).The papillary MS pattern was associated with MUC5AC and MUC6 expression,and the round pit and/or tubular MS patterns were associated with CD10expression.CONCLUSION:The MS pattern in ME-NBI findings is useful for predicting the morphologic category and mucin phenotype of GEDs,and ME-NBI findings may guide decisions regarding GED treatment.Hwa Mi Kang Gwang Ha Kim Do Youn Park Hong Ryeol Cheong Dong Hoon Baek Bong Eun Lee Geun Am Song 2014World Journal of Gastroenterology2014,20,42:4
12Is ineffective esophageal motility associated with gastropharyngeal reflux disease?显示文摘AIM: To evaluate the association between ineffective esophageal motility (IEM) and gastropharyngeal reflux disease (GPRD) in patients who underwent ambulatory 24-h dual-probe pH monitoring for the evaluation of supraesophageal symptoms. METHODS: A total of 632 patients who underwent endoscopy,esophageal manometry and ambulatory 24-h dual-pH monitoring due to supraesophageal symptoms (e.g. globus,hoarseness,or cough) were enrolled. Of them,we selected the patients who had normal esophageal motility and IEM. The endoscopy and ambulatory pH monitoring findings were compared between the two groups. RESULTS: A total of 264 patients with normal esophageal motility and 195 patients with the diagnosis of IEM were included in this study. There was no difference in the frequency of reflux esophagitis and hiatal hernia between the two groups. All the variables showing gastroesophageal reflux and gastropharyngeal reflux were not different between the two groups. The frequency of GERD and GPRD,as defined by ambulatory pH monitoring,was not different between the two groups. CONCLUSION: There was no association between IEM and GPRD as well as between IEM and GERD. IEM alone cannot be considered as a definitive marker for reflux disease.Kyung Yup Kim Gwang Ha Kim Dong Uk Kim Soo Geun Wang Byung Joo Lee Jin Choon Lee Do Youn Park Geun Am Song 2008World Journal of Gastroenterology2008,14,39:3
13Acute distal common bile duct angle is risk factor for postendoscopic retrograde cholangiopancreatography pancreatitis in beginner endoscopist显示文摘BACKGROUND Post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP)is a critical and poorly managed complication of ERCP.Endoscopists need to understand the risk factors for PEP.However,the majority of studies investigating ERCP-related risk factors have included well-trained endoscopists,with the issue of endoscopist experience on PEP incidence not having been systematically evaluated.AIM To explore the risk factors for PEP in beginner endoscopists without supervision.METHODS We performed a retrospective analysis of 293 patients,with naïve papilla and no history of pancreatitis,treated using bile duct cannulation.Patients were classified according to the endoscopist’s experience(beginner vs expert).The angle of the distal common bile duct(CBD)was measured as the angle between the lower wall of the bile duct and a vertical line extending to the lower wall of the bile duct on coronal view computed tomography.RESULTS After propensity matching,there were no differences between patients treated by the expert and beginner endoscopist with regard to age,sex,mean bile duct dilatation,and ratio of benign disease.The distal CBD angle was classified as acute(>30º)or obtuse(≤30º),based on the mean angle of 29.9ºfor the group.An acute distal CBD angle was a significant risk factor for PEP for beginner(P=0.049),but not expert.CONCLUSION For beginner endoscopists first performing unsupervised ERCP,cases with an obtuse distal CBD angle may be more appropriate to lower the risk of PEP.Sung Yong Han Dong Uk Kim Moon Won Lee Young Joo Park Dong Hoon Baek Gwang Ha Kim Geun Am Song 2020World Journal of Clinical Cases2020,8,1:3
