| 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 | Double guidewire technique vs transpancreatic precut sphincterotomy in difficult biliary cannulation显示文摘AIM:To compare the outcomes between doubleguidewire technique(DGT) and transpancreatic precut sphincterotomy(TPS) in patients with difficult biliary cannulation.METHODS:This was a prospective,randomized study conducted in single tertiary referral hospital in Korea.Between January 2005 and September 2010.A total of 71 patients,who bile duct cannulation was not possible and selective pancreatic duct cannulation was achieved,were randomized into DGT(n = 34) and TPS(n = 37) groups.DGT or TPS was done for selective biliary cannulation.We measured the technical success rates of biliary cannulation,median cannulation time,and procedure related complications.RESULTS:The distribution of patients after randomization was balanced,and both groups were comparable in baseline characteristics,except the higher percentage of endoscopic nasobiliary drainage in the DGT group(55.9% vs 13.5%,P < 0.001).Successful cannulation rate and mean cannulation times in DGT and TPS groups were 91.2% vs 91.9% and 14.1 ± 13.2 min vs 15.4 ± 17.9 min,P = 0.732,respectively.There was no significant difference between the two groups.The overall incidence of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis was 38.2% vs 10.8%,P < 0.011 in the DGT group and the TPS group;post-procedure pancreatitis was significantly higher in the DGT group.But the overall incidence of post-ERCP hyperamylasemia was no significant difference between the two groups;DGT group vs TPS group:14.7% vs 16.2%,P < 1.0.CONCLUSION:When free bile duct cannulation was difficult and selective pancreatic duct cannulation was achieved,DGT and TPS facilitated biliary cannulation and showed similar success rates.However,post-procedure pancreatitis was significantly higher in the DGT group. | Young Wook Yoo Sang-Woo Cha Woong Cheul Lee Sae Hee Kim Anna Kim Young Deok Cho | 2013 | World Journal of Gastroenterology2013，19，1： | 25 |
| 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 | Primary endoscopic approximation suture under cap-assisted endoscopy of an ERCP-induced duodenal perforation显示文摘Duodenal perforation during endoscopic retrograde cholangiopancreatography(ERCP) is a rare complication,but it has a relatively high mortality risk.Early diagnosis and prompt management are key factors for the successful treatment of ERCP-related perforation.The management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire trauma.However,the current standard treatment for duodenal free wall perforation is surgical repair.Recently,several case reports of endoscopic closure techniques using endoclips,endoloops,or fully covered metal stents have been described.We describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral centers.All the cases were simply managed by endoclips under transparent capassisted endoscopy.Based on the available evidence and our experience,endoscopic closure was a safe and feasible method even for duodenoscope-induced perforations.Our results suggest that endoscopists may be more willing to use this treatment. | Tae Hoon Lee Byoung Wook Bang Jee In Jeong Hyung Gil Kim Seok Jeong Seon Mee Park Don Haeng Lee Sang-Heum Park Sun-Joo Kim | 2010 | World Journal of Gastroenterology2010，16，18： | 19 |
| 5 | Is endoscopic ultrasonography still the modality of choice in preoperative staging of gastric cancer?显示文摘The treatment option for gastric cancer is usually based on preoperative staging by imaging modalities. Endoscopic ultrasonography(EUS) and computed tomography(CT) have been used as the diagnostic modality of choice in preoperative staging of gastric cancer. Magnetic resonance imaging(MRI) has been employed in several studies,and(18F) 2-Fluoro-2-deoxyglucose(FDG) positron emission tomography(PET) has emerged as a new promising imaging modality. The purpose of this article is to provide summarized information on preoperative staging using EUS,multi-detector row CT(MDCT),MRI and PET for gastric cancer. In T staging,both EUS and MDCT show high accuracy. MRI seemed to have better performance,but the number of MRI studies is limited. FDG-PET is not able to properly evaluate the depth of invasion. In N staging,the diagnostic accuracy of EUS,MDCT and MRI is not sufficient. In preoperative M staging,MDCT and FDGPET showed similar diagnostic accuracies. FDG-PET/CT fusion could be expected to show better performance in the future. Physicians should keep in mind that each diagnostic modality has advantages and limitations and choose an appropriate diagnostic strategy tailored for each patient. | Sung Wook Hwang Dong Ho Lee | 2014 | World Journal of Gastroenterology2014，20，38： | 16 |
| 6 | Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer显示文摘AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. | Jae Hyun Kim Jun Yeop Lee Hae Koo Kim Jin Wook Lee Sung Gyu Jung Kyoungwon Jung Sung Eun Kim Won Moon Moo In Park Seun Ja Park | 2017 | World Journal of Gastroenterology2017，23，3： | 16 |
| 7 | Does the bile duct angulation affect recurrence of choledocholithiasis?显示文摘AIM:To investigate whether bile duct angulation and T-tube choledochostomy influence the recurrence of choledocholithiasis.METHODS:We conducted a retrospective study including 259 patients who underwent endoscopic sphincterotomy and cholecystectomy for choledocholithiasis between 2000 and 2007.The imaginary line was drawn along the center of the bile duct and each internal angle was measured at the two angulation sites ofthe bile duct respectively.The values of both angles were added together.We then tested our hypothesis by examining whether T-tube choledochostomy was performed and stone recurrence occurred by reviewing each subject's medical records.RESULTS:The overall recurrence rate was 9.3% (24 of 259 patients).The mean value of sums of angles in the recurrence group was 268.3°± 29.6°,while that in the non-recurrence group was 314.8°± 19.9° (P < 0.05).Recurrence rate of the T-tube group was 15.9% (17 of 107),while that of the non T-tube group was 4.6% (7 of 152) (P < 0.05).Mean value of sums of angles after T-tube drainage was 262.5°± 24.6° and that before T-tube drainage was 298.0°± 23.9° in 22 patients (P < 0.05).CONCLUSION:The bile duct angulation and T-tube choledochostomy may be risk factors of recurrence of bile duct stones. | Dong Beom Seo Byoung Wook Bang Seok Jeong Don Haeng Lee Shin Goo Park Yong Sun Jeon Jung Il Lee Jin-Woo Lee | 2011 | World Journal of Gastroenterology2011，17，36： | 15 |
| 8 | 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 |
| 9 | Effect of the semen extract of Cuscuta chinensis on inflammatory responses in LPS-stimulated BV-2 microglia显示文摘AIM: To investigate the anti-inflammatory activities of the semen extract of Cuscuta chinensis Lam.(Cuscutae Semen; CS) on the production of inflammatory mediators, nitric oxide(NO), prostaglandin 2(PGE2), and proinflammatory cytokines in lipopolysaccharide(LPS)-stimulated BV-2 microglia. METHOD: BV-2 cells were treated with CS extract for 30 min, and then stimulated with LPS or without for 24 h. The levels of NO, PGE2 and proinflammatory cytokines were measured by Griess assay and ELISA. The expression of inducible nitric oxide synthase(iNOS), and cyclooxygenase(COX)-2 mRNA and protein was determined by RT-PCR and Western blot, respectively. The phosphorylation of extracellular signal-regulated kinase 1/2(ERK1/2), Jun N-terminal kinase(JNK), and p38 mitogen-activated protein kinase(MAPK), and the nuclear expression of nuclear factor(NF)-κB p65 were investigated by Western blot analysis. RESULTS: CS extract significantly decreased the production of NO and PGE2 by suppressing the expression of iNOS and COX-2 in activated microglia. CS extract decreased the production of TNF-α, IL-1β, and IL-6 by down-regulating their transcription levels. In addition, CS extract suppressed the phosphorylation of ERK1/2, JNK, and p38 MAPK, and the nuclear translocation of NF-κB p65 in activated microglia. CONCLUSION: These results indicate that CS extract is capable of suppressing the inflammatory response by microglia activation, suggesting that CS extract has potential in the treatment of brain inflammation. | Seok Yong Kang Hyo Won Jung Mi-Young Lee Hye Won Lee Seong Wook Chae Yong-Ki Park | 2014 | Chinese Journal of Natural Medicines2014，12，8： | 13 |
| 10 | Management of bleeding from pseudoaneurysms following pancreaticoduodenectomy显示文摘AIM:To review the clinical course and the management of pseudoaneurysms post-pancreaticoduodenectomy.METHODS: Medical records of 907 patients who underwent pancreaticoduodenectomies from January 1995 to May 2007 were evaluated retrospectively. The clinical course, management strategy, and outcome of ruptured pseudoaneurysms cases were analyzed.RESULTS: Twenty-seven (3.0%) of 907 cases had post-operative hemorrhage from ruptured pseudoan-eurysms. Pancreatic fistula was evident in 12 (44%) cases. Sentinel bleeding appeared in 21 (77.8%) cases. Of the 27 cases, 11 (41%) cases demonstrated bleeding pseudoaneurysm of the ligated gastroduodenal artery, 8 (30%) of the right, proper, common hepatic artery, 2 (7%) of the right gastric artery, and 4 (15%) of the peripancreatic arteries. The remaining two patients died due to sudden-onset massive hemorrhage and pseudoaneurysm rupture was suspected. Emergent operation was performed on 2 cases directly without angiography. Angiography was attempted in 23 cases. Eighteen (78.2%) cases succeeded to hemostasis; the five failed cases were explored. After embolization of the hepatic artery, five cases developed liver abscesses or infarction and a single case of hepatic failure expired. Gastroduodenal artery embolization with common hepatic artery stent insertion was performed to enhance hepatic artery flow in a single case and was successfully controlled.CONCLUSION: Bleeding pseudoaneurysms are among the most serious and fatal complications following pancreaticoduodenectomy. Diagnostic angiography has been preferred over endoscopy and is rapidly becoming the standard therapeutic treatment for bleeding pseudoaneurysms. | Hyung Geun Lee Jin Seok Heo Seong Ho Choi Dong Wook Choi | 2010 | World Journal of Gastroenterology2010，16，10： | 10 |
| 11 | Priapism secondary to penile metastasis of rectal cancer显示文摘Metastatic penile carcinoma is rare and usually originates from genitourinary tumors. The presenting symptoms or signs have been described as nonspecific except for priapism. Rectal adenocarcinoma is a very unusual source of metastatic penile carcinoma. We report a case of metastatic penile carcinoma that originated from the rectum. Symptomatic improvement occurred with palliative radiotherapy. | Ji Chan Park Wook Hyun Lee Min Kyu Kang Suk Young Park | 2009 | World Journal of Gastroenterology2009，15，33： | 10 |
| 12 | Association of chronic viral hepatitis B with insulin resistance显示文摘AIM:To investigate the relationship between chronic viral hepatitis B(CVHB) and insulin resistance(IR) in Korean adults.METHODS:A total of 7880 adults(3851 men,4029 women) who underwent a comprehensive medical examination were enrolled in this study.Subjects diagnosed with either diabetes mellitus,or any other disorder that could influence their insulin sensitivity,were rejected.Anthropometry,metabolic risk factors,hepatitis B surface antigen,hepatitis B surface antibody,hepatitis B core antibody,fasting plasma glucose and insulin were measured for all subjects.Homeostasis model assessment(HOMA),quantitative insulin check index(QUICKI),and Mf fm index were used for determining insulin sensitivity.Each participant was categorized into a negative,recovery,or CVHB group.To compare variables between groups,a t-test and/or one-way analysis of variance were used.Partial correlation coefficients were computed to present the association between insulin resistance and other variables.Multiple logistic regression analysis was used to assess the independent association between CVHB and IR.RESULTS:The mean age of men and women were 48.9 and 48.6 years,respectively.Subjects in the CVHB group had significantly higher waist circumference [(86.0 ± 7.7 cm vs 87.3 ± 7.8 cm,P = 0.004 in men),(78.3 ± 8.6 cm vs 80.5 ± 8.5 cm,P < 0.001 in women)],cystatin C [(0.96 ± 0.15 mg/dL vs 1.02 ± 0.22 mg/dL,P < 0.001 in men),(0.84 ± 0.15 mg/dL vs 0.90 ± 0.16 mg/dL,P < 0.001 in women)],fasting insulin [(5.47 ± 3.38 U/mL vs 6.12 ± 4.62 U/mL,P < 0.001 in men),(4.57 ± 2.82 U/mL vs 5.06 ± 3.10 U/mL,P < 0.001 in women)] and HOMA index [(1.24 ± 0.86 vs 1.43 ± 1.24,P < 0.001 in men),(1.02 ± 0.76 vs 1.13 ± 0.87,P = 0.033 in women)] compared to control group.The HOMA index revealed a positive correlation with body mass index(BMI)(r = 0.378,P < 0.001),waist circumference(r =0.356,P < 0.001),percent body fat(r = 0.296,P < 0.001),systolic blood pressure(r = 0.202,P < 0.001),total cholesterol(r = 0.134,P < 0.001),triglycerides(r = 0.292,P < 0.001),cystatin C(r = 0.069,P < 0.001) and uric acid(r = 0.142,P < 0.001).The QUICKI index revealed a negative correlation with BMI(r =-0.254,P < 0.001),waist circumference(r = 0-0.243,P < 0.001),percent body fat(r =-0.217,P < 0.001),systolic blood pressure(r =-0.132,P < 0.001),total cholesterol(r =-0.106,P < 0.001),triglycerides(r =-0.205,P < 0.001),cystatin C(r =-0.044,P < 0.001) and uric acid(r =-0.096,P < 0.001).For subjects identified with IR,the odds ratio of an accompanying diagnosis of chronic hepatitis B was 1.534(95% CI:1.158-2.031,HOMA index criteria) or 1.566(95% CI:1.124-2.182,QUICKI criteria) after adjustment for age,gender,BMI,and amount of alcohol consumption.CONCLUSION:Our study demonstrates that CVHB is associated with IR.CVHB may need to be monitored for occurrence of IR and diabetes mellitus. | Jeong Gyu Lee Sangyeoup Lee Yun Jin Kim Byung Mann Cho Joo Sung Park Hyung Hoi Kim JaeHun Cheong Dong Wook Jeong Yu Hyun Lee Young Hye Cho Mi Jin Bae Eun Jung Choi | 2012 | World Journal of Gastroenterology2012，18，42： | 10 |

| 15 | 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 |
| 16 | Exophytic inflammatory myofibroblastic tumor of the stomach in an adult woman:A rare cause of hemoperitoneum显示文摘Inflammatory myofibroblastic tumor (IMT) of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 55-year-old woman with a gastric IMT. She experienced sudden abdominal pain 4 d previously. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abnormal abdominal mass. Abdominal CT showed a mass of approximately 8 cm in the gastrocolic ligament. On laparoscopic exploration, unexpected hemoperitoneum of approximately 1.5 L of blood was found, and an exophytic gastric mass of approximately 10 cm, appeared from the anterior wall of the gastric body along the greater curvature. Laparoscopy further showed that non-clotting blood in the abdominal cavity seemed to be from the gastric tumor. After conversion to open surgery for more precise evaluation of the cause of hemoperitoneum and the large friable tumor, gastric wedge resection, including the tumor, was conducted. The final diagnosis was consistent with IMT that originated from the gastric wall. | Seong-Heum Park Jong-Han Kim Byung Wook Min Tae Jin Song Gil Soo Son Seung Joo Kim Sang Woo Lee Hwan-Hoon Chung Ju Han Lee Jun Won Um | 2008 | World Journal of Gastroenterology2008，14，1： | 8 |
| 17 | Efficacy of cap-assisted colonoscopy according to lesion location and endoscopist training level显示文摘AIM: To evaluate the efficacy of cap-assisted colonoscopy(CAC) for detection of colorectal polyps and adenomas according to the lesion location and endoscopist training level.METHODS: Patients 20 years or older, who underwent their first screening colonoscopy in a single tertiary center from May 2011 to December 2012 were enrolled in this study. All patients underwent either CAC or standard colonoscopy(SC), and all of the procedures were performed by 11 endoscopists(8 trainees and 3 experts). All procedures were performed with highdefinition colonoscopes and narrow band imaging. The eight trainees had experiences of performing 150 to 500 colonoscopies, and the three experts had experiences of performing more than 3000 colonoscopies. A 4-mmlong transparent cap was attached to the end of a colonoscope in the CAC group. We retrospectively evaluated the number of polyps and adenomas, polyp detection rate(PDR), and the number of adenomas and adenoma detection rate(ADR) according to the lesion location and endoscopist training level between CAC and SC. We also evaluated the number of polyps and adenomas according to their size between CAC and SC.RESULTS: Overall, PDR and ADR using CAC were significantly higher than those using SC for both whole colon(48.5% vs 40.7%, P = 0.012; 35.7% vs 28.3%, P = 0.012) and right-side colon(35.3% vs 26.6%, P = 0.002; 27.0% vs 16.9%, P < 0.001). The number of polyps and adenomas per patient using CAC was significantly higher than that using SC for both the whole colon(1.07 ± 1.59 vs 0.82 ± 1.31, P = 0.008; 0.72 ± 1.32 vs 0.50 ± 1.01, P = 0.003) and right-side colon(0.66 ± 1.18 vs 0.41 ± 0.83, P < 0.001; 0.46 ± 0.97 vs 0.25 ± 0.67, P < 0.001). In the trainee group, the PDR and ADR using CAC were significantly higher than those using SC for both the whole colon(46.7% vs 39.7%, P = 0.040; 33.9% vs 26.0%, P =0.012) and right-side colon(34.2% vs 26.5%, P = 0.015; 25.3% vs 15.9%, P = 0.001). In the expert group, the PDR and ADR using CAC were significantly higher than those using SC only for the right-side colon(42.1% vs 27.0%, P =0.035; 36.8% vs 21.0%, P = 0.020).CONCLUSION: CAC is more effective than SC for detection of colorectal polyps and adenomas, especially when performed by trainees and when the lesions are located in the right-side colon. | Dong Jun Kim Hyung Wook Kim Su Bum Park Dae Hwan Kang Cheol Woong Choi Joung Boom Hong Byoung Hoon Ji Chang Seok Lee | 2015 | World Journal of Gastroenterology2015，21，20： | 8 |

| 19 | Splenic infarction associated with sorafenib use in a hepatocellular carcinoma patient显示文摘Sorafenib,a multitargeted tyrosine kinase inhibitor,has been shown to improve survival in patients with advanced hepatocellular carcinoma(HCC).As the clinical use of sorafenib increases,many adverse effects have been reported,such as hand-foot skin reaction,diarrhea,anorexia,asthenia,alopecia,weight loss,hypertension and arterial thromboembolism.However,there are no prior reports of splenic infarction as an adverse effect of sorafenib.Here,a case of splenic infarction in a patient with HCC who was treated with sorafenib is reported. The patient had no other predisposing factors to explain the splenic infarction except for the administration of sorafenib.The splenic infarction improved after sorafenib was discontinued;however,the HCC progressed. | Sang Ock Kim Sang Young Han Yang Hyun Baek Sung Wook Lee Ji Sun Han Byung Geun Kim Jin Han Cho Kyung Jin Nam | 2011 | World Journal of Gastroenterology2011，17，2： | 7 |
| 20 | Effect of gadolinium incorporation on optical characteristics of YNbO_4:Eu^(3+) phosphors for lamp applications显示文摘Eu3+-doped (Y,Gd)NbO4 phosphor was synthesized by solid-state reaction for possible application in cold cathode fluorescent lamps. A broad absorption band with peak maximum at 272 nm was observed which was due to the charge transfer between Eu3+ ions and neighboring oxygen anions. A deep red emission at the peak wavelength of 612 nm was observed which could be attributed to the 5D0→7F2 transition in Eu3+ ions. The highest luminance for Y1-x-yGdyNbO4:Eux3+ under 254 nm excitation was achieved at Eu3+ concentration of 18 mol.% (x=0.18) and Gd3+ concentration of 8.2 mol.% (y=0.082). The luminance of Y0.738Gd0.082NbO4:Eu3+0.18 was higher than that of a typical commercial phosphor Y2O3:Eu3+ and the CIE chromaticity coordinate was (0.6490, 0.3506), which was deeper than that of Y2O3:Eu3+. The particle size of the synthesized phosphors was controlled by the NaCl flux and particle size as high as 8 μm with uniform size distribution of particles was obtained. | Sung Hwan Choi G.
