| 1 | 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 |
| 2 | Endoscopic submucosal dissection for early gastric cancer with undifferentiated-type histology:A meta-analysis显示文摘AIM: To evaluate the efficacy and safety of endoscopicsubmucosal dissection(ESD) for early gastric cancer(EGC) with undifferentiated-type histology.METHODS: A systematic literature review was conducted using the core databases. Complete resection,curative resection, en bloc resection, recurrence and adverse event rate were extracted and analyzed. A random effect model was applied. The methodological quality of the enrolled studies was assessed using the Newcastle-Ottawa Scale. Publication bias was evaluated using a funnel plot, the trim and fill method, Egger's test,and a rank correlation test.RESULTS: Fourteen retrospective studies between2009 and 2014 were identified(972 EGC lesions with undifferentiated-type histology). The total en bloc and complete resection rates were estimated as92.1%(95%CI: 87.4%-95.2%) and 77.5%(95%CI:69.3%-84%), respectively. The total curative resection rate was 61.4%(95%CI: 44.5%-75.9%). The overall recurrence rate was 7.6%(95%CI: 3.4%-16%).Limited to histologically diagnosed expanded-criteria lesions, the en bloc and complete resection rates were91.2% and 85.6%, respectively. The curative resection rate was 79.8%.CONCLUSION: In this analysis, ESD is a technically feasible treatment modality for EGC with undifferentiatedtype histology. Long-term studies are needed to confirm these therapeutic outcomes. | Chang Seok Bang Gwang Ho Baik In Soo Shin Jing Bong Kim Ki Tae Suk Jai Hoon Yoon Yeon Soo Kim Dong Joon Kim Woon Geon Shin Kyung Ho Kim Hak Yang Kim Hyun Lim Ho Seok Kang Jong Hyeok Kim Jin Bae Kim Sung Won Jung Sea Hyub Kae Hyun Joo Jang Min Ho Choi | 2015 | World Journal of Gastroenterology2015，21，19： | 14 |
| 3 | Application of artificial intelligence in gastroenterology显示文摘Artificial intelligence(AI) using deep-learning(DL) has emerged as a breakthrough computer technology. By the era of big data, the accumulation of an enormous number of digital images and medical records drove the need for the utilization of AI to efficiently deal with these data, which have become fundamental resources for a machine to learn by itself. Among several DL models, the convolutional neural network showed outstanding performance in image analysis. In the field of gastroenterology, physicians handle large amounts of clinical data and various kinds of image devices such as endoscopy and ultrasound. AI has been applied in gastroenterology in terms of diagnosis,prognosis, and image analysis. However, potential inherent selection bias cannot be excluded in the form of retrospective study. Because overfitting and spectrum bias(class imbalance) have the possibility of overestimating the accuracy,external validation using unused datasets for model development, collected in a way that minimizes the spectrum bias, is mandatory. For robust verification,prospective studies with adequate inclusion/exclusion criteria, which represent the target populations, are needed. DL has its own lack of interpretability.Because interpretability is important in that it can provide safety measures, help to detect bias, and create social acceptance, further investigations should be performed. | Young Joo Yang Chang Seok Bang | 2019 | World Journal of Gastroenterology2019，25，14： | 12 |
| 4 | Attempts to enhance the eradication rate of helicobacter pylori infection显示文摘Increasing rates of antimicrobial resistance to clarithromycin and metronidazole present challenges in maintaining optimal eradication rates.Knowledge of local antibiotic resistance and consumption pattern is important in selecting a reliable regimen.In addition,adverse effect profiles of therapeutic regimens are important and must be addressed to enhance compliance rates.Various methods of enhancing the eradication rates of Helicobacter pylori(H.pylori)have been investigated,including changing combinations or durations of established drugs,adding adjuvant drugs,or development of new molecules or agents.Bismuth-containing quadruple,sequential,concomitant,and levofloxacin-based triple therapies are replacing the long-standing standard of the triple regimen.Despite the encouraging results of these regimens,individualized approaches like treatment after antibiotics resistance test or CYP2C19genotyping would be the mainstream of future therapy.Because scientific,economic,and technical problems make these advance therapies unfit for widespread use,future development for H.pylori therapy should be directed to overcome individualized antibiotic resistance.Although various novel regimens and additive agents have indicated favorable outcomes,more studies or validations are needed to become a mainstream H.pylori therapy. | Chang Seok Bang Gwang Ho Baik | 2014 | World Journal of Gastroenterology2014，20，18： | 8 |
| 5 | Clinical characteristics of peptic ulcer perforation in Korea显示文摘AIM To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer(PPU).METHODS We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.RESULTS A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174(43.9%) patients who were examined for Helicobacter pylori(H. pylori) infection, 78(44.8%) patients were positive for H. pylori infection, 21(12.1%) were on non-steroidal anti-inflammatory drugs(NSAIDs) therapy, and 80(46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age(OR = 1.09, 95%CI: 1.04-1.16) and comorbidity(OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age(OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption(OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.CONCLUSION Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor. | Young Joo Yang Chang Seok Bang Suk Pyo Shin Tae Young Park Ki Tae Suk Gwang Ho Baik Dong Joon Kim | 2017 | World Journal of Gastroenterology2017，23，14： | 4 |
| 6 | Characteristics of nonvariceal upper gastrointestinal hemorrhage in patients with chronic kidney disease显示文摘AIM:To evaluate the clinical characteristics of nonvariceal upper gastrointestinal hemorrhage(NGIH)in patients with chronic kidney disease(CKD).METHODS:From 2003 to 2010,a total of 72 CKD patients(male n=52,72.2%;female n=20,27.8%)who had undergone endoscopic treatments for NGIH were retrospectively identified.Clinical findings,endoscopic features,prognosis,rebleeding risk factors,and mortality-related factors were evaluated.The characteristics of the patients and rebleeding-related data were recorded for the following variables:gender,age,alcohol use and smoking history,past hemorrhage history,endoscopic findings(the cause,location,and size of the hemorrhage and the hemorrhagic state),therapeutic options for endoscopy,endoscopist experience,clinical outcomes,and mortality.RESULTS:The average size of the hemorrhagic site was 13.7±10.2 mm,and the most common hemorrhagic site in the stomach was the antrum(n=21,43.8%).The most frequent method of hemostasis was combination therapy(n=32,44.4%).The incidence of rebleeding was 37.5%(n=27),and 16.7%(n=12)of patients expired due to hemorrhage.In a multivariate analysis of the risk factors for rebleeding,alcoholism(OR=11.19,P=0.02),the experience of endoscopists(OR=0.56,P=0.03),and combination endoscopic therapy(OR=0.06,P=0.01)compared with monotherapy were significantly related to rebleeding after endoscopic therapy.In a risk analysis of mortality after endoscopic therapy,only rebleeding was related to mortality(OR=7.1,P=0.02).CONCLUSION:Intensive combined endoscopic treatments by experienced endoscopists are necessary for the treatment of NGIH in patients with CKD,especially when a patient is an alcoholic. | Chang Seok Bang Yong Seop Lee Yun Hyeong Lee Hotaik Sung Hong Jun Park Hyun Soo Kim Jin Bong Kim Gwang Ho Baik Yeon Soo Kim Jai Hoon Yoon Dong Joon Kim Ki Tae Suk | 2013 | World Journal of Gastroenterology2013，19，43： | 3 |
| 7 | Osteoporosis and bone fractures in alcoholic liver disease:A meta-analysis显示文摘AIM: To evaluate the association between alcoholic liver disease(ALD) and bone fractures or osteoporosis. METHODS: Non-randomized studies were identified from databases(Pub Med, EMBASE, and the Cochrane Library). The search was conducted using Boolean operators and keywords, which included 'alcoholic liver diseases', 'osteoporosis', or 'bone fractures'. The prevalence of any fractures or osteoporosis, and bone mineral density(BMD) were extracted and analyzed using risk ratios and standardized mean difference(SMD). A random effects model was applied. RESULTS: In total, 15 studies were identified and analyzed. Overall, ALD demonstrated a RR of 1.944(95%CI: 1.354-2.791) for the development of bone fractures. However, ALD showed a RR of 0.849(95%CI: 0.523-1.380) for the development of osteoporosis. BMD was not significantly different between the ALD and control groups, although there was a trend toward lower BMD in patients with ALD(SMD in femur-BMD:-0.172, 95%CI:-0.453-0.110; SMD in spine-BMD:-0.169, 95%CI:-0.476-0.138). Sensitivity analyses showed consistent results. CONCLUSION: Current publications indicate significant associations between bone fractures and ALD, independent of BMD or the presence of osteoporosis. | Chang Seok Bang In Soo Shin Sung Wha Lee Jin Bong Kim Gwang Ho Baik Ki Tae Suk Jai Hoon Yoon Yeon Soo Kim Dong Joon Kim | 2015 | World Journal of Gastroenterology2015，21，13： | 1 |

| 11 | Changing trends and characteristics of peptic ulcer disease:A multicenter study from 2010 to 2019 in Korea显示文摘BACKGROUND The clinical trend and characteristics of peptic ulcer disease(PUD)have not fully been investigated in the past decade.AIM To evaluate the changing trends and characteristics of PUD according to age and METHODS We analyzed seven hospital databases converted into the Observational Medical Outcomes Partnership-Common Data Model between 2010 and 2019.We classified patients with PUD who underwent rapid urease tests or Helicobacter pylori(H.pylori)serology into three groups:H.pylori-related,drug[nonsteroidal anti-inflammatory drugs(NSAIDs)or aspirin]-related,and idiopathic(H.pylori/NSAID/aspirin-negative)PUD and compared the yearly trends and characteristics among the three groups.RESULTS We included 26785 patients in 7 databases,and the proportion of old age(≥65 years)was 38.8%.The overall number of PUD exhibited no decrease,whereas PUD in old age revealed an increasing trend(P=0.01 for trend).Of the 19601 patients,41.8%had H.pylori-related,36.1%had drug-related,and 22.1%had idiopathic PUD.H.pylorirelated PUD exhibited a decreasing trend after 2014(P=0.01),drug-related PUD demonstrated an increasing trend(P=0.04),and idiopathic PUD showed an increasing trend in the old-age group(P=0.01)during 10 years.Patients with drug-related PUD had significantly more comorbidities and concomitant ulcerogenic drugs.The idiopathic PUD group had a significantly higher number of patients with chronic liver disease.CONCLUSION With the aging population increase,the effects of concomitant ulcerogenic drugs and preventive strategies should be investigated in drug-induced PUD.Further studies are required to clarify the relationship between idiopathic PUD and chronic liver disease. | Yoon Jin Choi Tae Jun Kim Chang Seok Bang Yong Kang Lee Moon Won Lee Su Youn Nam Woon Geon Shin Seung In Seo | 2023 | World Journal of Gastroenterology2023，29，44： | 0 |
