| 1 | Risk factors affecting pancreatic fistulas after pancreaticoduodenectomy显示文摘AIM: To analyze the risk factors of pancreatic leakage after pancreaticoduodenectomy.METHODS: We retrospectively reviewed 172 consecutive patients who had undergone pancreatico-duodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.RESULTS: The incidence of developing pancreatic fistulas in patients older than 60 years of age was 21.7% (25/115), while the incidence was 8.8% (5/57) for younger patients; the difference was significant (P = 0.03). Patients with a dilated pancreatic duct had a lower rate of post-operative pancreatic fistulas than patients with a non-dilated duct (P = 0.001). Other factors, including clinical features, anastomotic methods, and pathologic diagnosis, did not show any statistical difference. CONCLUSION: Our study demonstrated that pancreatic fistulas are related to age and a dilated pancreatic duct. The surgeon must take these risk factors into consideration when performing a pancre-aticoduodenectomy. | Yun-Mee Choe Keon-Young Lee Cheong-Ah Oh Joung-Bum Lee Sun Keun Choi Yoon-Seok Hur Sei-Joong Kim Young Up Cho Seung-Ik Ahn Kee-Chun Hong Seok-Hwan Shin Kyung-Rae Kim | 2008 | World Journal of Gastroenterology2008，14，45： | 32 |
| 2 | Chronic gastrointestinal symptoms and quality of life in the Korean population显示文摘AIM: To evaluate the prevalence of chronic gastroin-testinal symptoms and their impact on health-related quality of life (HRQOL) in the Korean population. METHODS: A cross-sectional survey, using a reliable and valid Rome Ⅱ based questionnaire, was per-formed on randomly selected residents, between 18 and 69 years in age. All respondents were interviewed at their homes or offices by a team of interviewers. The impact of chronic gastrointestinal symptoms on HRQOL was assessed using the Korean version of the 36-item Short-Form general health survey (SF-36). RESULTS: Of the 1807 eligible subjects, 1417 (78.4%: male 762; female 655) were surveyed. Out of the respondents, 18.6% exhibited at least one chronic gastrointestinal symptom. The prevalence of gastro- esophageal reflux disease (GERD), defined as heart- burn and/or acid regurgitation experienced at least weekly, was 3.5% (95% CI, 2.6-4.5). The prevalence of uninvestigated dyspepsia, irritable bowel syndrome (IBS) and chronic constipation based on Rome Ⅱ cri- teria were 11.7% (95% CI, 10.1-13.5), 2.2% (95%CI, 1.5-3.1), and 2.6% (95% CI, 1.8-3.5) respectively. Compared with subjects without chronic gastrointesti- nal symptoms (n = 1153), those with GERD (n = 50), uninvestigated dyspepsia (n = 166) and IBS (n = 31) had signifi cantly worse scores on most domains of the SF-36 scales. CONCLUSION: The prevalence of GERD, uninvesti-gated dyspepsia and IBS were 3.5%, 11.7% and 2.2% respectively, in the Korean population. The health- related quality of life was signifi cantly impaired in sub-jects with GERD, uninvestigated dyspepsia and IBS in this community. | Jeong-Jo Jeong Myung-Gyu Choi Young-Seok Cho Seung-Geun Lee Jung-Hwan Oh Jae-Myung Park Yu-Kyung Cho In-Seok Lee Sang-Woo Kim Sok-Won Han Kyu-Yong Choi In-Sik Chung | 2008 | World Journal of Gastroenterology2008，14，41： | 21 |
| 3 | Acoustic radiation force impulse elastography for hepatocellular carcinoma-associated radiofrequency ablation显示文摘AIM:To evaluate the potential usefulness of acoustic radiation force impulse (ARFI) images for evaluation of hepatocellular carcinomas (HCC)-associated radiofrequency ablation. METHODS:From January 2010 to June 2010,a total of 38 patients with HCC including recurred HCCs after RFA underwent ARFI elastography. The brightness of tumor was checked and the shear wave velocity was measure-d for the-quantification of stiffne-ss. According to theb-rightne-ss,the-tumors we-re-classifie-d as b-righte-r,samecolor and darker compared with adjacent parenchyma. Using the same methods,8 patients with recurred HCCs after RFA state were evaluated about the brightness compared with adjacent RFA ablation area. RESULTS:In the 38 patients with HCCs,20 (52.6%)were brighter than surrounding cirrhotic parenchyma. Another 13 (34.2%) were darker. The others (5 cases,13.2%) were seen as the same color as the adjacent liver parenchyma. Post-RFA lesions were darker than previous tumor and surrounding parenchyma in all 38 cases. However,recurred HCCs were brighter than the treated site in all 8 cases. CONCLUSION:Using ARFI technique is helpful for differential diagnosis in order to detect recurred HCCs more easily in patients with confusing status. | Hee-Jin Kwon Myong-Jin Kang Jin-Han Cho Jong-Young Oh Kyung-Jin Nam Sang-Yeong Han Sung Wook Lee | 2011 | World Journal of Gastroenterology2011，17，14： | 21 |
| 4 | Plasma levels of acylated ghrelin in patients with functional dyspepsia显示文摘AIM:To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS:Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study.The functional dyspepsia patients were each diagnosed based on the Rome Ⅲ criteria.Eligible patients completed a questionnaire concerning the severity of 10 symptoms.Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit;electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS:There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia.However,in patients with functional dyspepsia,there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain(r =-0.427,P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety(r = 0.428,P =0.047).Additionally,there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria(%)(r =-0.522,P = 0.013).Interestingly,two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION:Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia. | Yeon Soo Kim Joon Seong Lee Tae Hee Lee Joo Young Cho Jin Oh Kim Wan Jung Kim Hyun Gun Kim Seong Ran Jeon Hoe Su Jeong | 2012 | World Journal of Gastroenterology2012，18，18： | 12 |
| 5 | Risk prediction platform for pancreatic fistula after pancreatoduodenectomy using artificial intelligence显示文摘BACKGROUND Despite advancements in operative technique and improvements in postoperative managements,postoperative pancreatic fistula(POPF)is a life-threatening complication following pancreatoduodenectomy(PD).There are some reports to predict POPF preoperatively or intraoperatively,but the accuracy of those is questionable.Artificial intelligence(AI)technology is being actively used in the medical field,but few studies have reported applying it to outcomes after PD.AIM To develop a risk prediction platform for POPF using an AI model.METHODS Medical records were reviewed from 1769 patients at Samsung Medical Center who underwent PD from 2007 to 2016.A total of 38 variables were inserted into AI-driven algorithms.The algorithms tested to make the risk prediction platform were random forest(RF)and a neural network(NN)with or without recursive feature elimination(RFE).The median imputation method was used for missing values.The area under the curve(AUC)was calculated to examine the discriminative power of algorithm for POPF prediction.RESULTS The number of POPFs was 221(12.5%)according to the International Study Group of Pancreatic Fistula definition 2016.After median imputation,AUCs using 38 variables were 0.68±0.02 with RF and 0.71±0.02 with NN.The maximal AUC using NN with RFE was 0.74.Sixteen risk factors for POPF were identified by AI algorithm:Pancreatic duct diameter,body mass index,preoperative serum albumin,lipase level,amount of intraoperative fluid infusion,age,platelet count,extrapancreatic location of tumor,combined venous resection,co-existing pancreatitis,neoadjuvant radiotherapy,American Society of Anesthesiologists’score,sex,soft texture of the pancreas,underlying heart disease,and preoperative endoscopic biliary decompression.We developed a web-based POPF prediction platform,and this application is freely available at http://popfrisk.smchbp.org.CONCLUSION This study is the first to predict POPF with multiple risk factors using AI.This platform is reliable(AUC 0.74),so it could be used to select patients who need especially intense therapy and to preoperatively establish an effective treatment strategy. | In Woong Han Kyeongwon Cho Youngju Ryu Sang Hyun Shin Jin Seok Heo Dong Wook Choi Myung Jin Chung Oh Chul Kwon Baek Hwan Cho | 2020 | World Journal of Gastroenterology2020，26，30： | 12 |
| 6 | Self-expandable metallic stents for palliation of patients with malignant gastric outlet obstruction caused by stomach cancer显示文摘AIM: To ascertain clinical outcome and complications of self-expandable metal stents for endoscopic palliation of patients with malignant obstruction of the gastrointestinal (GI) tract. METHODS: A retrospective review was performed throughout August 2000 to June 2005 of 53 patients with gastric outlet obstruction caused by stomach cancer. All patients had symptomatic obstruction including nausea, vomiting, and decreased oral intake. All received self-expandable metallic stents. RESULTS: Stent implantation was successful in all 53 (100%) patients. Relief of obstructive symptoms was achieved in 43 (81.1%) patients. No immediate stent-related complications were noted. Seventeen patients had recurrent obstruction (tumor ingrowth in 14 patients, tumor overgrowth in 1 patient, and partial distal stent migration in 2 patients). The mean survival was 145 d. Median stent patency time was 187 d. CONCLUSION: Endoscopic placement of self-expandable metallic stents is a safe and effective treatment for the palliation of patients with inoperable malignant gastric outlet obstruction caused by stomach cancer. | Tae Oh Kim Dae Hwan Kang Gwang Ha Kim Jeong Heo Geun Am Song Mong Cho Dong Heon Kim Mun Sup Sim | 2007 | World Journal of Gastroenterology2007，13，6： | 11 |
| 7 | Anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium-induced colitis model显示文摘AIM To evaluate the anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium(DSS)-induced colitis model.METHODS An acute colitis mouse model was induced by oral administration of 5% DSS in the drinking water for 7 d. In the treated group, rosuvastatin(0.3 mg/kg per day) was administered orally before and after DSS administration for 21 d. On day 21, mice were sacrificed and the colons were removed for macroscopic examination, histology, and Western blot analysis. In the in vitro study, IEC-6 cells were stimulated with50 ng/m L tumor necrosis factor(TNF)-α and then treated with or without rosuvastatin(2 μmol/L). The levels of reactive oxygen species(ROS), inflammatory mediators, and apoptotic markers were measured. RESULTS In DSS-induced colitis mice, rosuvastatin treatment significantly reduced the disease activity index and histological damage score compared to untreated mice(P < 0.05). Rosuvastatin also attenuated the DSSinduced increase of 8-hydroxy-2'-deoxyguanosine and NADPH oxidase-1 expression in colon tissue. Multiplex ELISA analysis revealed that rosuvastatin treatment reduced the DSS-induced increase of serum IL-2, IL-4, IL-5, IL-6, IL-12 and IL-17, and G-CSF levels. The increased levels of cleaved caspase-3, caspase-7, and poly(ADP-ribose) polymerase in the DSS group were attenuated by rosuvastatin treatment. In vitro, rosuvastatin significantly reduced the production of ROS, inflammatory mediators and apoptotic markers in TNF-α-treated IEC-6 cells(P < 0.05).CONCLUSION Rosuvastatin had the antioxidant, anti-inflammatory and anti-apoptotic effects in DSS-induced colitis model. Therefore, it might be a candidate anti-inflammatory drug in patients with inflammatory bowel disease. | Seung Kak Shin Jae Hee Cho Eui Joo Kim Eun-Kyung Kim Dong Kyun Park Kwang An Kwon Jun-Won Chung Kyoung Oh Kim Yoon Jae Kim | 2017 | World Journal of Gastroenterology2017，23，25： | 11 |

| 12 | Evaluation of esophageal function in patients with esophageal motor abnormalities using multichannel intraluminal impedance esophageal manometry显示文摘AIM: To evaluate the functional aspect of esophageal motility in healthy subjects and in patients who were referred for esophageal function testing using multichannel intraluminal impedance-esophageal manometry (MII-EM), and to assess the clinical utility of MII-EM. METHODS: From September 2003 to January 2004, we performed the MII-EM on healthy volunteers and all the patients who were referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. We analyzed the results, the impedance and the manometric findings. Some of the subjects had additional ambulatory 24-h pH study performed to diagnose gastroesophageal reflux disease (GERD). RESULTS: Among 89 studied subjects, the MII-EM findings showed normal esophageal motility in 50 (56.17%), ineffective esophageal motility (IEM) in 17 (19.10%), nutcracker esophagus in 7 (7.86%), achalasia in 4 (4.49%), and scleroderma esophagus in 11 (12.35%) cases. The completeness and the speed of bolus transit were in the order of nutcracker esophagus, normal manometry and IEM. Some of the swallows showing normal manometry and IEM had incomplete transit. In the achalasia and scleroderma esophagus, almost all the swallows had incomplete transit. The body amplitudes were higher for the swallows with complete transit than for the swallows with incomplete transit. There was not a significant difference in the manometric and impedance findings between the subjects with and without GERD. CONCLUSION: MII-EM is a useful tool in assessing theesophageal function in the patients having esophageal motility abnormality. The primary factors influencing the bolus transit are the amplitude of the esophageal body and normal peristalsis. | Yu Kyung Cho Myung-Gyu Choi Jae Myung Park Jung Hwan Oh Chang Nyol Paik Joon Wook Lee In Seok Lee Sang Woo Kim In-Sik Chung | 2006 | World Journal of Gastroenterology2006，12，39： | 8 |
| 13 | Gastric dysplasia may be an independent risk factor of an advanced colorectal neoplasm显示文摘AIM: To evaluate the relationship between gastric dysplasia and Helicobacter pylori (H pylori) and the occurrence of colorectal adenoma, and to defi ne the necessity for colonoscopy in patients with gastric dysplasia or H pylori infection.METHODS: From May 2005 to February 2008, 133 patients with established gastric dysplasia by gastroduo-denoscopy (EGD) were additionally investigated by colonoscopy. The authors compared results with those of 213 subjects who underwent both EGD and colonoscopy during the same period at the author’s Health Promotion Center as a control group. H pylori infection was evaluated in both the gastric dysplasia and control groups.RESULTS: The mean age of all 346 study subjects was 54.1 ± 10.5 years, and there were 258 (73%) men and 87 (27%) women. No signif icant difference was found between the H pylori positive and negative subjects in terms of the prevalence of colorectal adenoma and advanced colorectal adenoma (P = 0.261). Patients with gastric dysplasia showed no elevated risk of colorectal adenoma (OR = 0.910, 95% CI: 0.587-1.411, P = 0.738), but had a signif icantly higher risk of having advanced colorectal adenoma (OR = 3.382, 95% CI: 1.700-6.342, P = 0.000).CONCLUSION: The study emphasizes the need for colon surveillance in patients with gastric dysplasia, regardless of H pylori infection. | Rack Cheon Bae Seong Woo Jeon Han Jin Cho Min Kyu Jung Young Oh Kweon Sung Kook Kim | 2009 | World Journal of Gastroenterology2009，15，45： | 8 |

| 16 | An herbal formula,CGX,exerts hepatotherapeutic effects on dimethylnitrosamine-induced chronic liver injury model in rats显示文摘AIM: To evaluate the therapeutic effect of Chunggan extract (CGX), a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine (DMN)-induced chronic liver injury model in rats. METHODS: Liver injuries were induced in Wistar rats by injection of DMN (ip, 10 mg/mL per kg) for 3 consecutive days per week for 4 wk. The rats were administered with CGX (po, 100 or 200 mg/kg per day) or distilled water as a control daily for 4 wk starting from the 15th d of the DMN treatment. Biochemical parameters (serum albumin, bilirubin, ALP, AST and ALT), lipid peroxides, hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2, all of which are known to be associated with liver fibrosis, were analyzed using real-time PCR. RESULTS: CGX administration restored the spleen weight to normal after having been increased by DMN treatment. Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP (P < 0.05), ALT (P < 0.01), and AST (P < 0.01) that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly up-regulated expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2. Of these, the gene expression encoding PDGF-b and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration. CONCLUSION: CGX exhibits hepatotherapeutic proper- ties against chronic hepatocellular destruction and consequential liver fibrosis. | Jang-Woo Shin Jin-Young Son Se-Mi Oh Seung-Hyun Han Jing-Hua Wang Jung-Hyo Cho Chong-Kwan Cho Hwa-Seung Yoo Yeon-Weol Lee Myong-Min Lee Xiao Ping Hu Chang-Gue Son | 2006 | World Journal of Gastroenterology2006，12，38： | 5 |
| 17 | Association between hepatocellular carcinoma and tumor necrosis factor alpha polymorphisms in South Korea显示文摘AIM: To investigate associations between the tumor necrosis factor alpha(TNF-α)-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A polymorphisms and HCC in Korea.METHODS: Hepatocellular carcinoma(HCC) cases were diagnosed at CHA Bundang Medical Center from June 1996 to August 2008. The association between TNF-α polymorphisms and HCC was analyzed in 157HCC patients and 201 controls using a polymerase chain reaction-restriction fragment length polymorphism assay. We investigated five TNF-α polymorphisms,which are TNF-α-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A. The TNF-α genotype frequencies,genotype combinations and haplotypes were analyzed to disclose the association with HCC.RESULTS: None of the TNF-α polymorphisms was significantly associated with HCC. However,nine genotype combinations had associations with increased likelihood of HCC. Among them,TNF-α-1031/-857/-238 TT/CC/GA(AOR = 18.849,95%CI: 2.203-161.246,P = 0.007),TNF-α-1031/-308/-238 TT/GG/GA(AOR = 26.956,95%CI: 3.071-236.584,P = 0.003),and TNF-α-1031/-238 TT/GA(AOR = 21.576,95%CI: 2.581-180.394,P = 0.005) showed marked association with HCC. There were five haplotypes of TNF-α polymorphisms which were significantly associated with HCC. They are TNF-α-1031/-863/-857/-308/-238 T-C-C-G-A(OR = 25.824,95%CI: 1.491-447.223,P = 0.0005),TNF-α-1031/-857/-308/-238 T-C-G-A(OR = 12.059,95%CI: 2.747-52.950,P < 0.0001),TNF-α-1031/-857/-238 T-C-A(OR = 10.696,95%CI: 2.428-47.110,P = 0.0001),TNF-α-1031/-308/-238 T-G-A(OR = 7.556,95%CI: 2.173-26.280,P = 0.0002) and TNF-α-1031/-238 T-A(OR = 10.865,95%CI: 2.473-47.740,P = 0.0001). Moreover,HCC Okuda stage Ⅲ cases with the TNF-α-1031 CC genotype had better survival than those with the TT genotype(AOR = 5.795,95%CI: 1.145-29.323). CONCLUSION: Although no single TNF-α polymorphism is associated with HCC in this study,some TNF-α genotype combinations and haplotypes are associated with HCC. In addition,HCC Okuda stage Ⅲ cases with the TNF-α-1031 TT genotype may have a better prognosis than those with the CC genotype. | Suk Pyo Shin Nam Keun Kim Ju Hwan Kim Ju Ho Lee Jung Oh Kim Sung Hwan Cho Hana Park Mi Na Kim Kyu Sung Rim Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015，21，46： | 5 |
| 18 | Therapeutic effect of DA-9601 on chronic reflux gastritis induced by sodium taurocholate in rats显示文摘AIM: To investigate the therapeutic effects of DA-9601 on sodium taurocholate (TCA)-induced chronic reflux gastritis in SD rats.METHODS: In this study, we have investigated the therapeutic effects of DA-9601 on chronic erosive and atrophic gastritis induced by 6 mo of TCA administration (5 mmol/L in drinking water) in SD rats. RESULTS: Four weeks of DA-9601 administration (0.065%, 0.216% in rat chow), following the withdrawal of TCA treatment, resulted in a significant decrease in total length of erosions in rats in a dose-dependent manner. Furthermore, the indicators of atrophic gastritis, such as reduced mucosal thickness and reduction in the number of parietal cells, were improved by the administration of DA-9601 in a dose-related manner. DA-9601 also attenuated inflammatory cell infiltration and the proliferation of collagenous fiber in the gastric mucosa. The improvement in the reduction of the gastric mucus was observed in the rats receiving a high dose of DA-9601 (0.216%). The therapeutic effect of DA-9601 on experimental chronic erosive gastritis was superior to that of rebamipide (1.08% in rat chow). Biochemical analyses showed increased mucosal prostaglandin E2 and reduced glutathione levels by DA-9601 treatment. CONCLUSION: We suggest that DA-9601 is apromising agent for the treatment of chronic erosive and atrophic gastritis with an etiological factor of bile reflux. Increasedmucosal prostaglandin E2 and reduced glutathione by DA-9601 treatment may be therapeutic mechanisms for chronic erosive and atrophic gastritis. | Tae Young Oh Chang Yell Shin Yong Sung Sohn Dong Hwan Kim Byoung Ok Ahn Eun Bang Lee Cho Hyun Park | 2005 | World Journal of Gastroenterology2005，11，47： | 5 |
| 19 | Significant 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 | 2015 | World Journal of Gastroenterology2015，21，11： | 5 |
