| 1 | Endoscopic ultrasound-guided biliary drainage with placement of a fully covered metal stent for malignant biliary obstruction显示文摘AIM:To determine the utility of endoscopic ultrasoundguided biliary drainage(EUS-BD)with a fully covered self-expandable metal stent for managing malignant biliary stricture. METHODS:We collected data from 13 patients who presented with malignant biliary obstruction and underwent EUS-BD with a nitinol fully covered selfexpandable metal stent when endoscopic retrograde cholangiopancreatography(ERCP)fails.EUS-guided choledochoduodenostomy(EUS-CD)and EUS-guided hepaticogastrostomy(EUS-HG)was performed in 9 patients and 4 patients,respectively. RESULTS:The technical and functional success rate was 92.3%(12/13)and 91.7%(11/12),respectively. Using an intrahepatic approach(EUS-HG,n=4),there was mild peritonitis(n=1)and migration of the metal stent to the stomach(n=1).With an extrahepatic approach(EUS-CD,n=10),there was pneumoperitoneum(n=2),migration(n=2),and mild peritonitis (n=1).All patients were managed conservatively with antibiotics.During follow-up(range,1-12 mo),there was re-intervention(4/13 cases,30.7%)necessitated by stent migration(n=2)and stent occlusion(n=2). CONCLUSION:EUS-BD with a nitinol fully covered self-expandable metal stent may be a feasible and effective treatment option in patients with malignant biliary obstruction when ERCP fails. | Tae Hyeon Kim Seong Hun Kim Hyo Jeong Oh Young Woo Sohn Seung Ok Lee | 2012 | World Journal of Gastroenterology2012，18，20： | 16 |

| 3 | Hepatectomy vs radiofrequency ablation for colorectal liver metastasis:A propensity score analysis显示文摘AIM:To compare outcomes from radiofrequency ablation(RFA) and hepatectomy for treatment of colorectal liver metastasis(CRLM).METHODS:From January 2000 to December 2009,408 patients underwent curative intent treatment for CRLM.We excluded patients using the criteria:size of CRLM > 3 cm,number of CRLM ≥ 5,percutaneous RFA,follow-up period < 12 mo,double primary cancer,or treatment with both RFA and hepatectomy.We matched 51 patients who underwent RFA with 102 patients who underwent hepatectomy by propensity scores.RESULTS:The median follow-up period was 45 mo(range,12 mo to 158 mo).Hepatic recurrence was more frequent in the RFA than the hepatectomy group(P = 0.021) although extrahepatic recurrence curves were similar(P = 0.716).Survival curves of hepatectomy group were better than that of RFA for multiple,large(> 2 cm) CRLM(P = 0.034).However,survival curves were similar for single or small(≤ 2 cm) CRLM(P = 0.714,P = 0.740).CONCLUSION:Hepatectomy is better than RFA for the treatment of CRLM.However,RFA might be suitable for selected patients with single,small(≤ 2 cm) CRLM. | Huisong Lee Jin Seok Heo Yong Beom Cho Seong Hyeon Yun Hee Cheol Kim Woo Yong Lee Seong Ho Choi Dong Wook Choi | 2015 | World Journal of Gastroenterology2015，21，11： | 14 |
| 4 | Preoperative colonoscopy through the colonic stent in patients with colorectal cancer obstruction显示文摘AIM:To evaluate the feasibility of a preoperative colonoscopy through a self-expendable metallic stent(SEMS)and to identify the factors that affect complete colonoscopy.METHODS:A total of 48 patients who had SEMS placement because of acute malignant colonic obstruction underwent preoperative colonoscopy.After effective SEMS placement,patients who showed complete resolution of radiological findings and clinical signs of acute colon obstruction underwent a standard bowel preparation.Preoperative colonoscopy was then performed using a standard colonoscope.If the passage of colonoscope was not feasible gastroscope was used.After colonoscopy,cecal intubation time,grade of bowel preparation,tumor location,stent location,presence of synchronous polyps or cancer,damage to colonoscopy and bleeding,and stent migration after colonoscopy were recorded.RESULTS:Complete evaluation with colonoscope was possible in 30 patients(62.5%).In this group,adenoma was detected in 13 patients(43.3%).The factors that affected complete colonoscopy were also analyzed:Tumor location at an angle;stent placement at an angle;and stent expansion diameter,which affected complete colonoscopy significantly.However in multivariate analysis,stent expansion diameter was the only significant factor that affected complete colonoscopy.Complete evaluation using additional gastroscope was feasible in 42 patients(87.5%).CONCLUSION:Preoperative colonoscopy through the colonic stent using only conventional colonoscope was unfavorable.The narrow expansion diameter of the stent may predict unfavorable outcome.In such a case,using small caliber scope should be considered and may expect successful outcome. | Jin Su Kim Kang Moon Lee Sang Woo Kim Eun Jung Kim Chul Hyun Lim Seong Taek Oh Myung Gyu Choi Kyu Yong Choi | 2014 | World Journal of Gastroenterology2014，20，30： | 11 |
| 5 | Effect of focal laser photocoagulation in eyes with mild to moderate non-proliferative diabetic retinopathy显示文摘AIM:To report the effect of focal laser photocoagulation on both the severity of hard exudates(HEs) and the rate of disease progression in eyes with mild to moderate non-proliferative diabetic retinopathy(NPDR).METHODS: We retrospectively reviewed the medical records of 33 patients(60 eyes) who had been diagnosed with mild to moderate NPDR between January 2006 and December 2012.The patients were divided into 2 groups:Group A(38 eyes in 20 patients treated using focal laser photocoagulation) and Group B(treated without laser photocoagulation).We also reviewed the best corrected visual acuity measurements,and the fundus photographs taken at both baseline and follow-up visits. RESULTS: In Group A,HE severity grade had decreased significantly from baseline to the final visit(P <0.05),but this was not the case in Group B(P =0.662).The cumulative probabilities of retinopathy progression at 5y were 26% in Group A and 30% in Group B.KaplanMeier survival curves showed no significant difference between the groups with regard to retinopathy progression(P =0.805).CONCLUSION: Focal laser photocoagulation reduced the levels of HEs in eyes with mild to moderate NPDR.However,the treatment was not able to decelerate the progression of DR. | Seong Hun Jeong Jung Il Han Sung Won Cho Dong Won Lee Chul Gu Kim Tae Gon Lee Jong Woo Kim | 2016 | International Journal of Ophthalmology(English edition)2016，9，10： | 10 |
| 6 | Predicting tumor response after preoperative chemoradiation using clinical parameters in rectal cancer显示文摘AIM: To evaluate the clinical parameters and identify a better method of predicting pathological complete response (pCR). METHODS: We enrolled 249 patients from a database of 544 consecutive rectal cancer patients who underwent surgical resection after preoperative chemoradiation therapy (PCRT). A retrospective review of morphological characteristics was then performed to collect data regarding rectal examination findings. A scoring model to predict pCR was then created. To validate the ability of the scoring model to predict complete regression.RESULTS: Seventy patients (12.9%) achieved a pCR. A multivariate analysis found that pre-CRT movability (P = 0.024), post-CRT size (P = 0.018), post-CRT morphology (P = 0.023), and gross change (P = 0.009) were independent predictors of pCR. The accuracy of the scoring model was 76.8% for predicting pCR with the threshold set at 4.5. In the validation set, the accuracy was 86.7%. CONCLUSION: Gross changes and morphological findings are important predictors of pathological response. Accordingly, PCRT response is best predicted by a combination of clinical, laboratory and metabolic information. | Chan Ho Park Hee Cheol Kim Yong Beom Cho Seong Hyeon Yun Woo Yong Lee Young Suk Park Doo Ho Choi Ho-Kyung Chun | 2011 | World Journal of Gastroenterology2011，17，48： | 6 |
| 7 | 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 |

| 9 | Intrauterine midgut volvulus without malrotation:Diagnosis from the 'coffee bean sign'显示文摘Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a 'coffee bean sign'. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention. | Jun Seok Park Seong Jae Cha Beom Gyu Kim Yong Seok Kim Yoo Shin Choi In Taik Chang Gwang Jun Kim Woo Seok Lee Gi Hyeon Kim | 2008 | World Journal of Gastroenterology2008，14，9： | 4 |
| 10 | Repeat hepatic resection in patients with colorectal liver metastases显示文摘AIM:To investigate the survival outcomes of secondaryhepatectomy for recurrent colorectal liver metastases(CRLM).METHODS:From October 1994 to December 2009,patients with CRLM who underwent surgical treatment with curative intent were investigated.Patients were divided into two groups:patients who underwent primary hepatectomy(Group 1)and those who underwent secondary hepatectomy for recurrent CRLM(Group 2).RESULTS:Survival and prognostic factors were analyzed.A total of 461 patients were included:406patients in Group 1 and 55 patients in Group 2.After a median 39-mo(range,3-195 mo)follow-up,there was a significant difference between Groups 1 and 2in terms of disease-free survival(P=0.029)although there was no significant difference in overall survival(P=0.206).Secondary hepatectomy was less effective in patients with multiple recurrent CRLM than primary hepatectomy for initial CRLM(P=0.008).Multiple CRLM and radiofrequency ablation therapy were poor prognostic factors of secondary hepatectomy in multivariate Cox regression analysis(P=0.006,P=0.004,respectively).CONCLUSION:Secondary hepatectomy for single recurrent CRLM is as effective as primary surgical treatment for single recurrent CRLM.However,secondary hepatectomy for multiple recurrent CRLM is less effective than that for single recurrent CRLM. | Huisong Lee Seong Ho Choi Yong Beom Cho Seong Hyeon Yun Hee Cheol Kim Woo Yong Lee Jin Seok Heo Dong Wook Choi Kyung Uk Jung Ho-Kyung Chun | 2015 | World Journal of Gastroenterology2015，21，7： | 4 |

| 13 | Prognostic value of 18-fluorodeoxyglucose positron emission tomography-computed tomography in resectable colorectal cancer显示文摘AIM:To assess the prognostic value of preoperative 18 fluorodeoxyglucose positron emission tomography(FDG-PET)/computed tomography(CT) in patients with resectable colorectal cancer.METHODS:One hundred sixty-three patients with resectable colorectal cancer who underwent FDG-PET/CT before surgery were included.Patient data including pathologic stage at presentation,histology,treatment,disease-free survival and the maximum standardized uptake value(SUVmax) of the primary tumor on FDG-PET/CT were retrospectively analyzed.Median follow up duration was 756(range,419-1355).The primary end point was disease-free survival.RESULTS:Twenty-five of 163 patients(15.3%) had recurrences.The median SUVmax values of the recurrence and no-recurrence groups were 8.9(range,5-24) and 8.2(range,0-23,P = 0.998).Receiver operating characteristic(ROC) curve analysis showed no significant association between SUVmax and recurrence(area under the curve = 0.5,P = 0.998,95% CI:0.389-0.611).Because a statistically significant value was not found,SUVmax was dichotomized at its median of 8.6.The disease-free survival curve was analyzed using the median SUVmax(8.6) as the cut off.Univariate and multivariate analysis did not provide evidence that disease-free survival rates for the subgroups defined by the median SUVmax were significantly different(P = 0.52,P = 0.25).CONCLUSION:Our study suggests that the high FDG uptake of primary mass in resectable colorectal cancer doesn't have a significant relationship with tumor recurrence and disease-free survival. | Jang Eun Lee Sang Woo Kim Jin Su Kim Kyu Yong Choi Won Kyung Kang Seong Taek Oh Ie Ryung Yoo Sung Hoon Kim | 2012 | World Journal of Gastroenterology2012，18，36： | 3 |

| 15 | Spectrum of final pathological diagnosis of gastric adenoma after endoscopic resection显示文摘AIM: To investigate how many discrepancies occur in patients before and after endoscopic treatment of referred adenoma and the reason for these results. METHODS: We retrospectively reviewed data from 554 cases of 534 patients who were referred from primary care centres for adenoma treatment and treated for endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) at Chungnam National University Hospital, from July 2006 to June 2009. Reendoscopy was examined in 142 cases and biopsywas performed in 108 cases prior to treatment. Three endoscopists (1, 2 and 3) performed all EMRs or ESDs and three pathologists (1, 2 and 3) diagnosed most of the cases. Transfer notes, medical records and endoscopic pictures of these cases were retrospectively reviewed and analyzed. RESULTS: Adenocarcinoma was 72 (13.0%) cases in total 554 cases after endoscopic treatment of referred adenoma. When the grade of dysplasia was high (55.0%), biopsy number was more than three (22.7%), size was no smaller than 2.0 cm (23.2%), morphologic type was depressed (35.8%) or yamada type Ⅳ (100%), and color was red (30.9%) or mixed-or-undetermined (25.0%), it had much more malignancy rate than the others (P < 0.05). All 18 cases diagnosed as adenocarcinoma in the re-endoscopic forceps biopsy were performed by endoscopist 1. There were different malignancy rates according to the pathologist (P = 0.027). CONCLUSION: High grade dysplasia is the most important factor for predicting malignancy as a final pathologic diagnosis before treating the referred gastric adenoma. This discrepancy can occur mainly through inappropriately selecting a biopsy site where cancer cells do not exist, but it also depends on the pathologist to some extent. | Kwan Woo Nam Kyu Sang Song Heon Young Lee Byung Seok Lee Jae Kyu Seong Seok Hyun Kim Hee Seok Moon Eaum Seok Lee Hyun Yong Jeong | 2011 | World Journal of Gastroenterology2011，17，47： | 2 |
| 16 | Relationship between compressive and tensile strengths of roller-compacted concrete显示文摘The abstract roller-compacted concrete(RCC) is a zero slump concrete comprising the same materials as that of conventional concrete with different proportions. The RCC must be compacted to reach its final form. The effects of hydration and aggregate interlock on its strength are considerable. For similar binder contents, the compressive strength of the RCC is generally higher than that of the conventional concrete; however, the tensile strength of RCC may not be superior to that of the conventional concrete. Adequate tensile strength is necessary to resist fatigue cracking, particularly in pavement applications. However, the compressive strength is frequently used in assessing the quality control and quality assurance of pavements. Therefore, the relationship between the compressive and tensile strengths of the RCC should be analyzed. Unfortunately, only a few studies have been conducted on this relationship.The objective of this study is to identify the difference between the indirect tensile strengths of the RCC and those of the conventional concrete as well as develop relationship equations to evaluate the compressive and tensile strengths. In this study, regression equations are developed to estimate the indirect tensile strengths, which are known as flexural and splitting tensile strengths, using the compressive strength of the RCC. The results show that the flexural strength of the RCC is within the predicted values obtained from the conventional concrete equations for a given compressive strength. In contrast,the splitting tensile strength of the RCC is relatively lower than that of the conventional concrete for the given compressive strength. | Chamroeun Chhorn Seong Jae Hong Seung Woo Lee | 2018 | Journal of Traffic and Transportation Engineering(English Edition)2018，5，3： | 2 |
