| 1 | Safety and efficacy of tenofovir in chronic hepatitis B-related decompensated cirrhosis显示文摘AIM To evaluate the safety and efficacy of tenofovir disoproxil fumarate(TDF) as a first-line therapy in decompensated liver disease. METHODS We enrolled 174 chronic hepatitis B-related liver cirrhosis patients treated with 300 mg/d TDF at six Korean centers. Of the 174 cirrhosis patients, 57 were assigned to the decompensated cirrhosis group and 117 were assigned to the compensated cirrhosis group. We followed the patients for 12 mo and evaluated clinical outcomes, including biochemical, virological, and serological responses. We also evaluated changes in hepatic and renal function and compared the decompensated and compensated cirrhosis groups. RESULTS The 1-year complete virological response(CVR) and Hepatitis B e antigen(HBe Ag) seroconversion were seen in 70.2% and 14.2% in the decompensated cirrhosis group, respectively. The rates of HBe Ag seroconversion/loss and ALT normalization at month 12 were similar in both groups. TDF treatment was also effective for decreasing the level of hepatitis B virus(HBV) DNA in both groups, but CVR was higher in the compensated group(88.9% vs 70.2%, P = 0.005). Tenofovir treatment for 12 mo resulted in improved Child-Turcotte-Pugh(CTP) and model for end-stage liver disease(MELD) scores in decompensated group(P < 0.001). Of the 57 decompensated patients, 39(68.4%) achieved CTP class A and 27(49.1%) showed improvement in the CTP score of 2 points after 12 mo of TDF. The observed rate of confirmed 0.5 mg/d L increases in serum levels of creatinine in the decompensated and compensated cirrhosis group were 7.0% and 2.5%, respectively(P < 1.000).CONCLUSION TDF therapy in decompensated cirrhosis patients was effective for decreasing HBV DNA levels and improving hepatic function with relatively lower CVR than in compensated cirrhosis. Thus, physicians should carefully monitor not only renal function but also treatment responses when using TDF in decompensated cirrhosis patients. | Soon Kyu Lee Myeong Jun Song Seok Hyun Kim Byung Seok Lee Tae Hee Lee Young Woo Kang Suk Bae Kim Il Han Song Hee Bok Chae Soon Young Ko Jae Dong Lee | 2017 | World Journal of Gastroenterology2017，23，13： | 14 |
| 2 | Endoscopic ultrasound-guided choledochoduodenostomies with fully covered self-expandable metallic stents显示文摘AIM:To investigate the long-term outcomes of endoscopic ultrasound-guided choledochoduodenostomy(EUS-CDS) with a fully covered self-expandable metallic stent(FCSEMS).METHODS:From April 2009 to August 2010,15 patients with distal malignant biliary obstructions who were candidates for alternative techniques for biliary decompression due to a failed endoscopic retrograde cholangiopancreatography(ERCP) were included.These 15 patients consisted of 8 men and 7 women and had a median age of 61 years(range:30-91 years).The underlying causes of the distal malignant biliary obstruction were pancreatic cancer(n = 9),ampulla of Vater cancer(n = 2),renal cell carcinoma(n = 1),advanced gastric cancer(n = 1),lymphoma(n = 1),and duodenal cancer(n = 1).RESULTS:The technical success rate of EUS-CDS with an FCSEMS was 86.7%(13/15),and functional success was achieved in 100%(13/13) of those cases.In two patients,the EUS-CDS failed because an FCSEMS with a delivery device could not be passed into the common bile duct.The mean duration of stent patency was 264 d.Early adverse events developed in three patients(3/13,23.1%),including self-limited pneumoperitoneum in two patients and cholangitis requiring stent reposition in one patient.During the follow-up period(median:186 d,range:52-388 d),distal stent migration occurred in four patients(4/13,30.8%).In 3 patients,the FCSEMS could be reinserted through the existing choledochoduodenal fistula tract.CONCLUSION:EUS-CDS with an FCSEMS is technically feasible and can lead to effective palliation of distal malignant biliary obstructions after failed ERCP. | Tae Jun Song Yil Sik Hyun Sang Soo Lee Do Hyun Park Dong Wan Seo Sung Koo Lee Myung-Hwan Kim | 2012 | World Journal of Gastroenterology2012，18，32： | 8 |
| 3 | 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 |

| 6 | Clinical course of ulcerative colitis patients who develop acute pancreatitis显示文摘AIM To investigate the clinical course of ulcerative colitis(UC)patients who develop acute pancreatitis.METHODS We analyzed 3307 UC patients from the inflammatory bowel disease registry at Asan Medical Center from June 1989 to May 2015.The clinical course of UC patients who developed acute pancreatitis was compared with that of non-pancreatitis UC patients.RESULTS Among 51 patients who developed acute pancreatitis,13(0.40%)had autoimmune,10(0.30%)had aminosalicylate-induced,and 13(1.73%)had thiopurineinduced pancreatitis.All 13 patients with autoimmune pancreatitis(AIP)had type 2 AIP.Two(15.4%)patients had pre-existing AIP,and three(23.1%)patients developed AIP and UC simultaneously.Compared to non-pancreatitis patients,AIP patients had UC diagnosed at a significantly younger age(median,22.9 years vs 36.4 years;P=0.001).AIP and aminosalicylate-induced pancreatitis patients had more extensive UC compared to non-pancreatitis patients.All patients with pancreatitis recovered uneventfully,and there were no recurrences.Biologics were used more frequently in aminosalicylate-and thiopurine-induced pancreatitis patients compared to non-pancreatitis patients[adjusted OR(95%CI),5.16(1.42-18.67)and6.90(1.83-25.98),respectively].Biologic utilization rate was similar among AIP and non-pancreatitis patients[OR(95%CI),0.84(0.11-6.66)].Colectomy rates for autoimmune,aminosalicylate-induced,and thiopurineinduced pancreatitis,and for non-pancreatitis patients were 15.4%(2/13),20%(2/10),15.4%(2/13),and7.3%(239/3256),respectively;the rates were not significantly different after adjusting for baseline disease extent.CONCLUSION Pancreatitis patients show a non-significant increase in colectomy,after adjusting for baseline disease extent. | Jong Wook Kim Sung Wook Hwang Sang Hyoung Park Tae Jun Song Myung-Hwan Kim Ho-Su Lee Byong Duk Ye Dong-Hoon Yang Kyung-Jo Kim Jeong-Sik Byeon Seung-Jae Myung Suk-Kyun Yang | 2017 | World Journal of Gastroenterology2017，23，19： | 3 |
| 7 | Diagnostic performance of the current risk-stratified approach with computed tomography for suspected choledocholithiasis and its options when negative finding显示文摘Background:Several studies evaluated the current guideline of the American Society for Gastrointestinal Endoscopy(ASGE)and reported only suboptimal accuracy.This study evaluated the diagnostic performance of the ASGE guideline based on computed tomography(CT)and role of endoscopic ultrasonography(EUS)and magnetic resonance cholangiopancreatography(MRCP)in patients with suspected choledocholithiasis but negative CT finding.Methods:Patients with suspected choledocholithiasis undergoing ERCP between January 2016 and January 2017 were retrospectively analyzed.All patients underwent CT to detect choledocholithiasis.EUS or MRCP was performed when the CT scan showed negative findings.Patients were classified into the high and intermediate-risk groups,based on predictors from the ASGE criteria.Results:Of 583 patients with suspected choledocholithiasis,340(58.3%)had stones on ERCP(65.9%in the high-risk group and 40.6%in the intermediate-risk group).The accuracy of ASGE guideline for CT was 63.98%(79.12%sensitivity,42.80%specificity)and 36.02%(20.88%sensitivity,57.20%specificity)in the high-risk and intermediate-risk groups,respectively.In 103 patients in the high-risk group underwent both CT and US,the accuracy of CT was higher than that of US for detecting choledocholithiasis(78.64%vs.53.40%),with a significant difference in area under the curve(AUC)(0.78 vs.0.59,P<0.001).Of 339 with negative CT finding,the accuracy of EUS was higher than that of MRCP(90.91%vs.82.76%),but with no significant difference in AUC(0.91 vs.0.83,P=0.347).Conclusions:CT-based ASGE guideline showed superior diagnostic performance than US for predicting choledocholithiasis.The diagnostic options,EUS or MRCP,with negative CT finding showed comparable performance.Therefore,the diagnostic modality should be selected based on availability,experience,cost,and contraindications. | Hyun Woo Lee Tae Jun Song Do Hyun Park Sang Soo Lee Dong-Wan Seo Sung Koo Lee Myung-Hwan Kim Jae Hyuck Jun Ji Eun Moon Yeon Han Song | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，4： | 3 |
| 8 | Recent advances in endoscopic retrograde cholangiopancreatography in Billroth II gastrectomy patients: A systematic review显示文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)in patients with Billroth Ⅱ gastrectomy has been considered a challenging procedure due to the surgically altered gastrointestinal anatomy.However,there has been a paucity of comparative studies regarding ERCP in Billroth Ⅱ gastrectomy cases because of procedure-related morbidity and mortality and practical and ethical limitations.This systematic and comprehensive review was performed to obtain a recent perspective on ERCP in Billroth Ⅱ gastrectomy patients.AIM To systematically review the literature regarding ERCP in Billroth Ⅱ gastrectomy patients.METHODS A systematic review was performed on the literature published between May 1975 and January 2019.The following electronic databases were searched:PubMed,EMBASE,and Cochrane Library.The outcomes of successful afferent loop intubation and successful selective cannulation and occurrence of adverse events were assessed.RESULTS A total of 43 studies involving 2669 patients were included.The study designs were 36(83.7%)retrospective cohort studies,4(9.3%)retrospective comparative studies,2(4.7%)prospective comparative studies,and 1(2.3%)prospective cohort study.Of a total of 2669 patients,there were 1432 cases(55.6%)of sideviewing endoscopy,664(25.8%)cases of forward-viewing endoscopy,171(6.6%)cases of balloon-assisted enteroscopy,169(6.6%)cases of anterior obliqueviewing endoscopy,64(2.5%)cases of dual-lumen endoscopy,31(1.2%)cases of colonoscopy,and 14(0.5%)cases of multiple bending endoscopy.The overall success rate of afferent loop intubation was 91.3%(2437/2669),and the overall success rate of selective cannulation was 87.9%(2346/2437).A total of 195 cases(7.3%)of adverse events occurred.The success rates of afferent loop intubation and the selective cannulation rate for each type of endoscopy were as follows:side-viewing endoscopy 98.2%and 95.3%;forward-viewing endoscopy 97.4%and 95.2%;balloon-assisted enteroscopy 95.4%and 97.5%;oblique-viewing endoscopy 94.1%and 97.5%;and dual-lumen endoscopy 82.8%and 100%,respectively.The rate of bowel perforation was slightly higher in side-viewing endoscopy(3.6%)and balloon-assisted enteroscopy(4.1%)compared with forward-viewing endoscopy(1.7%)and anterior oblique-viewing endoscopy(1.2%).Mortality only occurred in side-viewing endoscopy(n=9,0.6%).CONCLUSION The performance of ERCP in the Billroth Ⅱ gastrectomy population has been improving with choice of various type of endoscope and sphincter management.More comparative studies are needed to determine the optimal strategy to perform safe and effective ERCP in Billroth Ⅱ gastrectomy patients. | Tae Young Park Tae Jun Song | 2019 | World Journal of Gastroenterology2019，25，24： | 3 |
| 9 | Analysis on sports and recreation activity-related eye injuries presenting to the Emergency Department显示文摘AIM:To investigate the incidence and general characteristics of sports-related eye injuries in patients visiting the Emergency Department. METHODS: A cross-sectional,multi-center,observational study.Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled.All data were prospectively collected between March and September 2010 using a questionnaire.Eye injuries that occurred during risky sports were examined by gender and age.Additionally,the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity.Continuous variables were compared using Student's t-test and categorical variables were compared using Chi-square test.RESULTS: A total of 446 patients had sports-related eye injuries.Teenagers(10-19 years old) and young adults(20-29 years old) had the most eye injuries.Eye injuries accounted for 0.2% of Emergency Department patients.Baseball was the most common cause of sports-related eye injuries,followed by soccer and hiking.Protective gear was worn by 9.4% of all patients.Patients that were 30-39 years of age had the highest rate of protective gear use,followed by patients that were 40-49 years of age.The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking.CONCLUSION: Although injuries were most common in patients below the age of 10 years,these patients had the lowest rate of protective eyewear use.Injuries in adults over 40 years of age most commonly occurred during hiking,but the rate of protective eyewear use was low.Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established.For older adults,eye protection should be encouraged,especially during hiking. | Sungbae Moon Hyun Wook Ryoo Jae Yun Ahn Jung Bae Park Kang Suk Seo Sang Do Shin Kyoung Jun Song Kang Hyun Lee In Sool Yoo Jin Seong Cho Hyun Ho Ryu Tae Oh Jeong Seok Ran Yeom Young Taek Kim Sung Ok Hong | 2016 | International Journal of Ophthalmology(English edition)2016，9，10： | 3 |
| 10 | The efficacy of fluoropyrimidine.based adjuvant chemotherapy on biliary tract cancer after R0 resection显示文摘Background: The optimal treatment strategy for biliary tract cancer(BTC) after curative?intent resection remains con?troversial. The purpose of this study was to evaluate the efficacy of fluoropyrimidine?based adjuvant chemotherapy for BTC patients undergoing microscopically margin?negative(R0) resection.Methods: We retrospectively analyzed the clinical data of BTC patients who underwent curative?intent R0 resection. Patients were eligible if they received either fluoropyrimidine?based adjuvant chemotherapy or observation after R0 resection.Results: A total of 153 patients were included. In the entire patient cohort, no significant differences were observed in 5?year overall survival(OS) rates(48.4% vs. 39.6%, P = 0.439) or 3?year recurrence?free survival(RFS) rates(49.1% vs. 39.5%, P = 0.299) between patients who received fluoropyrimidine?based adjuvant chemotherapy or observation. However, for patients with stages Ⅱ and Ⅲ BTC, chemotherapy significantly improved 5?year OS rate(52.4% vs. 35.6%, P = 0.002) and 3?year RFS rate(55.5% vs. 39.1%, P = 0.021) compared with observation.Conclusion: Fluoropyrimidine?based adjuvant chemotherapy may prolong the survival of patients with stages Ⅱ and Ⅲ BTC after R0 resection. | Young Saing Kim Chi-Young Jeong Haa-Na Song Tae Hyo Kim Hong Jun Kim Young-Joon Lee Soon Chan Hong | 2017 | Chinese Journal of Cancer2017，36，5： | 2 |

| 18 | Endoscopic gastrojejunostomy with a natural orifice transluminal endoscopic surgery technique显示文摘AIM: To determine the technical feasibility and safety of an endoscopic gastrojejunostomy with a pure natural orifice transluminal endoscopic surgery (NOTES) technique using a T-anchoring device in a porcine survival model. METHODS: An endoscopic gastrojejunostomy with a pure NOTES technique using a T-anchoring device was performed on 10 healthy female minipigs weighing approximately 40 kg each under general anesthesia. All procedures were performed with a transgastric approach using a 2-channel therapeutic endoscope. RESULTS: The transgastric gastrojejunostomy was technically successful in all cases. A total of four to sixstitched pairs of a T-anchoring device were used to secure the anastomosis. The median time required to enter the peritoneal cavity and pull the small bowel into the stomach was 34 min (range: 19-41 min); the median time required to suture the anastomosis was 67 min (range: 44-78 min). An obstruction of the efferent limb occurred in one case, and a rupture of the anastomosis site occurred in another case. As a result, the functional success rate was 80% (8/10). Small bowel adhesion to the stomach and liver occurred in one case, but the anastomosis was intact without leakage or obstruction. CONCLUSION: A transgastric gastrojejunostomy with a T-anchoring device may be safe and technically feasible. A T-anchoring device may provide a simple and effective endoscopic suturing method. | Tae Jun Song Dong Wan Seo Su Hui Kim Do Hyun Park Sang Soo Lee Sung Koo Lee Myung-Hwan Kim | 2013 | World Journal of Gastroenterology2013，19，22： | 1 |
