| 1 | Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution. | Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee | 2010 | World Journal of Gastroenterology2010，16，34： | 26 |
| 2 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |

| 4 | Identification of an anticancer compound against HT-29 cells from Phellinus linteus grown on germinated brown rice显示文摘Objective:To isolate and identify the anticancer compound against proliferation of human colon cancer cells from ethyl acetate(EtOAc)extract ol Phellinus linteus grown on germinated brown rice(PB).Methods:EtOAc extract of PB was partitioned with n-hexane,EtOAc,and water-saturated n-butanol.Anticancer compound of n-hexane layer was isolated and identified by HPLC and NMR,respectively.Cytotoxicity against HT-29 cells was tested by SRB assay.Results:The n-hexane layer obtained after solvent fractionation of PB EtOAc extracts showed a potent anticancer activity against the HT-29 cell line.Atractylenolide I,a eudesmane-type sesquiterpene lactone,a major anticancer substance of PB,was isolated from the n-hexane layer by silica gel column chromatography and preparative-HPLC.This structure was elucidated by one-and two-dimensional NMR spectroscopic data.Atractylenolide I has not been reported in mushrooms or rice as of yet.The isolated compound dose-dependently inhibited the growth of HT-29 human colon cancer cells.Conclusions:Atractylenolide I might contribute to the anticancer effect of PB. | Tae-Il Jeon Chang-Hwa Jung Jeong-Yong Cho Dong Ki Park Jae-Hak Moon | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，10： | 9 |
| 5 | Clinicopathologic 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 | 2014 | World Journal of Gastroenterology2014，20，20： | 9 |
| 6 | Clinical significance and risk factors of postembolization fever in patients with hepatocellular carcinoma显示文摘AIM:To investigate tumor response and survival in patients with postembolization fever(PEF) and to determine the risk factors for PEF.METHODS:Four hundred forty-three hepatocellular carcinoma(HCC) patients who underwent the first session of transcatheter arterial chemoembolization(TACE) between January 2005 and December 2009 were analyzed retrospectively.PEF was defined as a body temperature greater than 38.0 ℃ that developed within 3 d of TACE without evidence of infection.The tumor progression-free interval was defined as the interval from the first TACE to the second TACE based on mRECIST criteria.Clinical staging was based on the American Joint Committee on Cancer tumor,node,metastases(TNM) classification of malignant tumors.All patients were admitted before their 1 st TACE treatment,and blood samples were obtained from all patients before and after treatment.Clinicoradiological variables and host-related variables were compared between two groups:patients with PEF vs patients without PEF.Additionally,variables related to 20-mo mortality and tumor progression-free survival were analyzed.RESULTS:The study population comprised 370(85.4%) men and 73(14.6%) women with a mean age of 62.29 ± 10.35 years.A total of 1836 TACE sessions were conducted in 443 patients,and each patient received between 1 and 27(mean:4.14 ± 3.57) TACE sessions.The mean follow-up duration was 22.23 ± 19.6 mo(range:0-81 mo).PEF developed in 117 patients(26.41%) at the time of the first TACE session.PEF was not associated with 20-mo survival(P = 0.524) or computed tomography(CT) response(P = 0.413) in a univariate analysis.A univariate analysis further indicated that diffuse-type HCC(P = 0.021),large tumor size(≥ 5 cm)(P = 0.046),lipiodol dose(≥ 7 mL,P = 0.001),poor blood glucose control(P = 0.034),alanine aminotransferase(ALT) value after TACE(P = 0.004) and C-reactive protein(CRP) value after TACE(P = 0.036) served as possible risk factors correlated with PEF.The ALT value after TACE(P = 0.021) and lipiodol dose over 7 mL(P = 0.011) were independent risk factors for PEF in the multivariate analysis.For the 20-mo survival,poor blood sugar control(P < 0.001),portal vein thrombosis(P = 0.001),favorable CT response after TACE(P < 0.001),initial aspartate aminotransferase(P = 0.02),initial CRP(P = 0.042),tumor size(P < 0.001),TNM stage(P < 0.001) and lipiodol dose(P < 0.001) were possible risk factors in the univariate analysis.Tumor size(P = 0.03),poor blood sugar control(P = 0.043),and portal vein thrombosis(P = 0.031) were significant predictors of survival in the multivariate analysis.Furthermore,the tumor progression-free interval was closely associated with CRP > 1 mg/dL(P = 0.003),tumor size > 5 cm(P < 0.001),tumor type(poorly defined)(P < 0.001),and lipiodol dose(> 7 mL,P < 0.001).CONCLUSION:PEF has no impact on survival at 20 mo or radiologic response.However,the ALT level after TACE and the lipiodol dose represent significant risk factors for PEF. | Chung Hwan Jun Ho Seok Ki Hoon Ki Lee Kang Jin Park Seon Young Park Sung Bum Cho Chang Hwan Park Young Eun Joo Hyun Soo Kim Sung Kyu Choi Jong Sun Rew | 2013 | World Journal of Gastroenterology2013，19，2： | 7 |
| 7 | A comparative study on serologic profiles of virus hepatitis B显示文摘INTRODUCTIONHepatitis B viral infection, one of the most-prevalent liver disorders in China and Korea, is aserious infectious disease as it has the potential ofprogressing into liver cirrhosis and primary hepaticcarcinoma. China and Korea both belong to high-risk endemic regions of viral hepatitis[1]. TheHBsAg positive rates in China ranged from 6.9% -17.9% by age, race and test methods[2-5]. | BoYOUl Cho Moran Ki Hung Bae Park | 2001 | World Journal of Gastroenterology2001，7，1： | 6 |
| 8 | Effectiveness and safety of traditional Chinese herbs in children with cough variant asthma: a systematic review and Meta-analysis显示文摘OBJECTIVE:To systematically investigate the clinical effectiveness and safety of traditional Chinese herbs(TCHs)as an alternative to conventional medicine(CM)in children with cough variant asthma(CVA).METHODS:Randomized controlled trial(RCT)studies that were published from their inceptions to March 31,2020,were identified from the electronic databases of China National Knowledge Infrastructure,Wangfang,Pub Med,and Cochrane Central Library.The primary outcome of the review was the total effective rate(TER),and the secondary outcomes were immunoglobulin E(Ig E),peak expiratory flow(PEF),adverse drug reactions,and relapse rates of interventions.RESULTS:For the Meta-analysis,13 studies involving 992 children with CVA were included.In terms of TER and Ig E,the experimental interventions of TCH,when compared with the control interventions of CM,on pediatric CVA were found to be significantly effective(P<0.0001),whereas for spirometry,PEF was not significantly improved in the TCH group(P=0.48).The incident rates of adverse drug reaction and relapse were found to be significantly lower in the TCH group than those in the CM group(P=0.02 and P<0.0001,respectively).CONCLUSION:Compared with CM therapy,the effects of TCH therapy on pediatric CVA were significantly beneficial in terms of TER and Ig E,but not for PEF,and the methodological quality of included studies was poor.Therefore,the results should be interpreted with caution.More randomized controlled trials with rigorous experimental methodologies are required for objectivity in the future. | Kyou-Hwan Han Ki Haeng Cho CUI Shanqin Lily Lin Jaejong Kim | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 6 |

| 10 | Amomum villosum induces longitudinal bone growth in adolescent female rats显示文摘OBJECTIVE:This study was conducted to evaluate the effect of Amomum villosum on longitudinal bone growth.METHODS:Adolescent female Sprague-Dawley rats were divided into 3 groups and treated for 4 days:control(distilled water,p.o.),recombinant human growth hormone(rhGH;100 μg/kg,s.c.),and A.villosum(500 mg/kg,p.o.) groups.On day 3,tetracycline(20 g/kg,i.p.) was injected for growth plate identification.On days 2,3 and 4,5-bromo-2'-deoxyuridine(BrdU)(50 mg/kg,i.p.) was injected to label proliferating cells.On day 5,tibias were dissected and fixed in 4% paraformaldehyde,dehydrated,and sectioned for immunohistochemistry and histomorphometry.RESULTS:The rate of bone growth in the A.villosum and rhGH groups increased to(410 ± 44) and(389 ± 46) μm/day(P<0.01),respectively,as compared with the control(330.7 ± 34.7) μm/day.The thickness of the growth plates also increased to(591 ± 37) and(598 ± 32) μm,respectively,as compared with the control(524± 89) μm(P<0.001).The number of BrdU-positive cells in the chondrocytes of the A.villosum and rhGH groups was also significantly higher(126±24) and(143±18) cells/mm 2,respectively) than in the control(109 ± 25) mm 2(P<0.05).Insulin-like growth factor-1 and bone morphogenetic protein-2 in the A.villosum and rhGH groups were highly expressed in the growth plate as compared with the control samples,indicating increased bone formation.CONCLUSIONS:A.villosum could be used to treat growth retardation during adolescence. | Sun Haeng Lee Ji Young Kim Hocheol Kim Seul Ki Park Cho Young Kim Sun Yong Chung Gyu Tae Chang | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 6 |
| 11 | Development of tenofovir disoproxil fumarate resistance after complete viral suppression in a patient with treatment-na?ve chronic hepatitis B: A case report and review of the literature显示文摘Tenofovir disoproxil fumarate(TDF) is a potent nucleo-tide analogue that is recommended as first-line therapy for patients with chronic hepatitis B. The results of a longitudinal study of TDF treatment demonstrated no development of resistance. We observed one treatment-na?ve chronic hepatitis B(CHB) patient who developed TDF resistance after complete viral suppression during long-term TDF treatment. A 37-year-old HBe Ag-positive man received TDF 300 mg/d for 43 mo. The hepatitis B virus(HBV) DNA titer was 8 log_(10) copies/m L at baseline and became undetectable at 16 mo after treatment. However, the HBV DNA titer rebounded to 7.5 log_(10) copies/m L at 43 mo after treatment. We performed full sequencing to find mutation sites associated with virologic breakthrough. The results showed 9 mutation sites, most of which had not been well-known as mutation sites. We changed the therapy from tenofovir to entecavir with a regimen of 0.5 mg once daily. After 4 mo, the HBV DNA titer decreased to 267 copies/m L, and the liver enzyme levels were normalized. | Woo Hee Cho Hyun Jae Lee Ki Bae Bang Seok Bae Kim Il Han Song | 2018 | World Journal of Gastroenterology2018，24，17： | 5 |
| 12 | Comparison of brush and basket cytology in differential diagnosis of bile duct stricture at endoscopic retrograde cholangiopancreatography显示文摘BACKGROUND: A previous report has identified a significantly higher sensitivity of cancer detection for dedicated grasping basket than brushing at endoscopic retrograde cholangiopancreatography (ERCP). This study aimed to compare the diagnostic accuracy of Geenen brush and Dormia basket cytology in the differential diagnosis of bile duct stricture.METHOD: The current study enrolled one hundred and fourteen patients who underwent ERCP with both Geenen brush and Dormia basket cytology for the differential diagnosis of bile duct stricture at our institution between January 2008 and December 2012.RESULTS: We adopted sequential performances of cytologic samplings by using initial Geenen brush and subsequent Dormia basket cytology in 59 patients and initial Dormia basket and subsequent Geenen brush cytology in 55 patients.Presampling balloon dilatations and biliary stentings for the stricture were performed in 17 (14.9%) and 107 patients (93.9%),respectively. The sensitivity, specificity, positive predictive value,negative predictive value, and accuracy of Geenen brush cytology for the diagnosis of malignant bile duct stricture were 75.0%,100.0%, 100.0%, 66.7% and 83.3%, respectively, and those of Dormia basket cytology were 64.5%, 100.0%, 100.0%, 58.5% and 76.3%, respectively (P=0.347 and 0.827 for sensitivity and accuracy, respectively). The good and excellent cellular yields (≥ grade 2) were obtained by Geenen brush and Dormia basket cytology in 88 (77.2%) and 79 (69.3%) patients, respectively.CONCLUSION: The sensitivity, specificity and accuracy of biliary sampling with a Dormia basket are comparable to those with conventional Geenen brush cytology in the detection of malignant bile duct stricture. | Ki Bae Bang Hong Joo Kim Jung Ho Park Dong Il Park Yong Kyun Cho Chong Il Sohn Woo Kyu Jeon Byung Ik Kim | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，6： | 5 |
| 13 | Current status and challenges in sentinel node navigation surgery for early gastric cancer显示文摘Although a number of feasibility studies for sentinel node(SN) concepts in gastric cancer have been conducted since 2000, there remains a debate regarding detailed detection techniques and oncological safety. Two important multicenter phase II clinical trials were performed in Japan that used different methods and reached different conclusions; one confirmed acceptable results with a false-negative rate of 7%, and the other showed an unacceptably high false-negative rate of 46.4%. The Sentinel Node Oriented Tailored Approach(SENORITA)trial is a multicenter randomized controlled phase III trial being performed in Korea. Patient enrollment is now complete and the long-term results are currently awaited. Recently, an image-guided SN mapping technique using infrared ray/fluorescence was introduced. This method might be a promising technology because it allows the clear visualization of SNs. With regard to the primary tumor, the non-exposed endoscopic wall-inversion surgery technique and non-exposure endolaparoscopic full-thickness resection with simple suturing technique have been reported. These methods prevent abdominal infection and tumor seeding and can be good alternatives to conventional laparoscopic gastric wedge resection. For indications, SN navigation surgery can be extended to patients who underwent non-curative endoscopic resection. Although a few studies have been performed on these patients, sentinel concepts may be beneficial to patients as they omit the need for additional gastrectomy. SN navigation surgery can lead to actual organ-preserving surgery and plays a key role in improving the quality of life of patients with early gastric cancer in the future. | Bang Wool Eom Young-II Kim Hong Man Yoon Soo-Jeong Cho Jong Yeul Lee Chan GyooKim Soo Jin Kim Ji Yoon Rho Seok Ki Kim Myeong-Cherl Kook Young-Woo Kim Keun Won | 2017 | Chinese Journal of Cancer Research2017，29，2： | 5 |
| 14 | Stomach cancer screening and preventive behaviors in relatives of gastric cancer patients显示文摘AIM:To investigate gastric cancer screening and preventive behaviors among the relatives of patients with gastric cancer[i.e.,gastric cancer relatives(GCRs)].METHODS:We examined the Korean National Health and Nutrition Examination Survey 2005(KNHANESⅢ) database and compared the gastric cancer screening and preventive behaviors of GCRs(n=261)with those of non-GCRs(n=454)and controls without a family history of cancer(n=2842).RESULTS:The GCRs were more likely to undergo gastric cancer screening compared with the control group(39.2%vs 32.3%,adjusted odds ratio:1.43,CI:1.05-1.95),although the absolute screening rate was low.Dietary patterns and smoking rates did not differ significantly between the groups,and a high proportion of GCRs reported inappropriate dietary habits(i.e.,approximately 95%consumed excessive sodium,30% were deficient in vitamin C,and 85%were deficient in dietary fiber).CONCLUSION:The gastric cancer screening and preventive behaviors of GCRs have yet to be improved.To increase awareness among GCRs,systematic family education programs should be implemented. | Jung Min Kang Dong Wook Shin Young Min Kwon Sang Min Park Min Sun Park Jin Ho Park Ki Young Son Be Long Cho | 2011 | World Journal of Gastroenterology2011，17，30： | 4 |
| 15 | Letting Go is Never Easy:Abscission and Receptor- Like Protein Kinases显示文摘Abscission is the process by which plants discard organs in response to environmental cues/stressors,or as part of their normal development.Abscission has been studied throughout the history of the plant sciences and in numerous species.Although long studied at the anatomical and physiological levels,abscission has only been elucidated at the molecular and genetic levels within the last two decades,primarily with the use of the model plant Arabidopsis thaliana.This has led to the discovery of numerous genes involved at all steps of abscission,including key pathways involving receptor-like protein kinases(RLKs).This review covers the current knowledge of abscission research,highlighting the role of RLKs. | Chad E.Niederhuth Sung Ki Cho Kati Seitz John C.Walker | 2013 | Journal of Integrative Plant Biology2013，55，12： | 3 |
| 16 | A pilot study of single-use endoscopy in screening acute gastrointestinal bleeding显示文摘AIM:To investigate the feasibility of a single-use endoscopy as an alternative procedure to nasogastric lavage in patients with acute gastrointestinal(GI) bleeding.METHODS:Patients who presented with hematemesis,melena or hematochezia were enrolled in this study.EG scan and conventional esophagogastroduodenoscopy(EGD) were subsequently performed.Active bleeding was defined as blood in the stomach,and inactive bleeding was defined as coffee ground clots and clear fluid in the stomach.The findings were recorded and compared.RESULTS:Between January and March,2011,13 patients that presented with hematemesis(n = 4),melena(n = 6),or bleeding from a previous nasogastric feeding tube(n = 3),were enrolled in this study.In 12 patients with upper GI bleeding,the EG scan device revealed that 7 patients had active bleeding and 5 patients had inactive bleeding,whereas conventional EGD revealed that 8 patients had active bleeding and 4 patients had inactive bleeding.The sensitivity and specificity of the EG scan device was 87.5% and 100% for active bleeding,with conventional EGD serving as a reference.No complication were reported during the EG scan procedures.CONCLUSION:The EG scan is a feasible device for screening acute upper GI bleeding.It may replace nasogastric lavage for the evaluation of acute upper GI bleeding. | Jae Hee Cho Hee Man Kim Sangheun Lee Yu Jin Kim Ki Jun Han Hyeon Geun Cho Si Young Song | 2013 | World Journal of Gastroenterology2013，19，1： | 3 |

| 18 | Comparison of a novel bedside portable endoscopy device with nasogastric aspiration for identifying upper gastrointestinal bleeding显示文摘AIM: To compare outcomes using the novel portable endoscopy with that of nasogastric(NG) aspiration in patients with gastrointestinal bleeding.METHODS: Patients who underwent NG aspiration for the evaluation of upper gastrointestinal(UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration.RESULTS: In total, 129 patients who had GI bleedingsigns or symptoms were included in the study(age 64.46 ± 13.79, 91 males). The UGI tract(esophagus, stomach, and duodenum) was the most common site of bleeding(81, 62.8%) and the cause of bleeding was not identified in 12 patients(9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration(85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding(88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration(20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy.CONCLUSION: The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding. | Jong Hwan Choi Jae Hyuk Choi Yoo Jin Lee Hyung Ki Lee Wang Yong Choi Eun Soo Kim Kyung Sik Park Kwang Bum Cho Byoung Kuk Jang Woo Jin Chung Jae Seok Hwang | 2014 | World Journal of Gastroenterology2014，20，25： | 3 |
| 19 | Perceived risk as a barrier to appropriate diagnosis of irritable bowel syndrome显示文摘AIM:To evaluate perceived risk,diagnostic testing,and acceptance of a diagnosis of irritable bowel syndrome(IBS)among the Korean laypersons.METHODS:We designed a conceptual framework to evaluate the health-seeking behavior of subjects based on a knowledge,attitude,and practice model.We developed a vignette-based questionnaire about IBS based on a literature review and focused group interviews.The vignette described a 40-year-old woman who meets the RomeⅢcriteria for IBS without red-flag signs.It was followed by questions about demographic characteristics,health behaviors,IBS symptoms,risk perception,perceived need for diagnostic tests,and acceptance of a positive diagnosis of IBS.Weplanned a nationwide survey targeting laypersons without IBS and between the ages of 20 and 69 years.Survey participants were selected by quota sampling stratified by gender,age,and nationwide location.A multivariate logistic model was constructed based on literature reviews,univariate analysis,and a stepwise selection method to investigate correlations between the perceived risk,need for diagnostic tests,and acceptance of a positive diagnosis.RESULTS:Of 2354 eligible households,1000 subjects completed the survey and 983 subjects were analyzed,excluding those who met symptom criteria for IBS.After reading the IBS vignette,the majority of subjects(86.8%)responded that the patient was at increased risk of severe disease.The most frequent concern was colon cancer(59.8%),followed by surgical condition(51.5%).Most subjects responded the patient needs diagnostic tests(97.2%).Colonoscopy was the most commonly required test(79.5%).Less than half of the respondents requested a stool examination(45.0%),blood test(40.7%),abdominal ultrasound(36.0%),or computed tomography(20.2%).The subjects who felt increased risk were more likely to see a need for colonoscopy[adjusted odds ratio(a OR)=2.10,95%CI:1.38-3.18].When asked about the positive diagnosis,the most frequent response was that'the patient would not be reassured'(65.7%).The increased risk perception group was less likely to be reassured by a positive diagnosis of IBS,compared to the other respondents(a OR=0.52,95%CI:0.34-0.78).CONCLUSION:For IBS diagnosis,increased risk perception is a possible barrier to the appropriate use of diagnostic tests and to the patient’s acceptance of a positive diagnosis. | Eunmi Ahn Ki Young Son Dong Wook Shin Min Kyu Han Hyejin Lee Ah Reum An Eun Ho Kim Be Long Cho | 2014 | World Journal of Gastroenterology2014，20，48： | 2 |
| 20 | Factors associated with use of gastric cancer screening services in Korea显示文摘AIM: To identify the factors associated with participation in gastric cancer screening programs. METHODS: Using data from the Korea National Health and Nutrition Examination Survey 2005 (KNHANES Ⅲ), a nationwide health-related surveyin Korea, a cross-sectional study was performed to investigate the multiple factors associated with gastric cancer screening attendance among persons aged at least 40 years. The study population included 4593 individuals who completed a gastric cancer screening questionnaire and had no previous cancer history. Four groups ofindividual-level or environmental level covariates were considered as potential associated factors.RESULTS: Using KNHANES Ⅲdata, an estimated31.71% of Korean individuals aged at least 40 years adhered to gastric cancer screening recommendations. Subjects who graduated from elementary school[adjusted odds ratio (aOR), 1.66; 95% CI: 1.21-2.26], middle/high school (aOR, 1.38; 95% CI: 1.01-1.89), and university or higher (aOR, 1.64; 95% CI: 1.13-2.37) were more likely to undergo gastric cancer screening than those who received no formal education at all. The population with the highest income tertile had more attendance at gastric screening compared to those with the lowest income tertile (aOR, 1.36; 95% CI: 1.06-1.73). Gastric screening was also negatively associated with excessive alcohol consumption (aOR, 0.71; 95% CI: 0.53-0.96). A positive attitude to preventive medical evaluation was significantly associated with better participation in gastric cancer screening programs (aOR, 5.26; 95% CI: 4.35-6.35). CONCLUSION: Targeted interventions for vulnerable populations and public campaigns about preventive medical evaluation are needed to increase gastric cancer screening participation and reduce gastric cancer mortality. | Young Min Kwon Hyung Taek Lim Kiheon Lee Be Long Cho Min Sun Park Ki Young Son Sang Min Park | 2009 | World Journal of Gastroenterology2009，15，29： | 2 |
