| 1 | Diagnostic value of AFP-L3 and PIVKA-Ⅱin hepatocellular carcinoma according to total-AFP显示文摘AIM:To evaluate diagnostic value ofα-fetoprotein (AFP)-L3 and prothrombin induced by vitamin K absence-Ⅱ(PIVKA-Ⅱ)in hepatocellular carcinoma(HCC). METHODS:One hundred and sixty-eight patients during routine HCC surveillance were included in this study.Of the 168 patients,90(53.6%)had HCC including newly developed HCC(n=82)or recurrent HCC after treatment(n=8).Sera were obtained during their first evaluation for HCC development and at the time of HCC diagnosis before commencing HCC treatment.HCC was diagnosed by histological examination,appropriate imaging characteristics-computed tomography or magnetic resonance imaging.Control sera were collected from 78 patients with benign liver disease(BLD),which were obtained during routine surveillance with a suspicion of HCC.AFP,AFP-L3 and PIVKA-Ⅱwere measured in the same serum by microchip capillary electrophoresis and liquid-phase binding assay on a micro-total analysis system Wako i30 auto analyzer.The performance characteristics of three tests and combined tests for the diagnosis of HCC were obtained using receiver operating characteristic curves in all populations and subgroups with AFP<20 ng/mL. RESULTS:Of 90 HCC patients,38(42.2%)patients had AFP<20 ng/mL,20(22.2%)patients had AFP 20-200 ng/mL and 32(35.6%)patients had AFP>200 ng/mL.Of the 78 BLD patients,74(94.9%)patients had AFP<20 ng/mL.After adjustment for age and HBV infection status,AFP-L3 levels were higher in HCC than in BLD among patients with low AFP levels(<20 ng/mL)(P<0.001).In a total of 168 patients,areas under the curve(AUC)for HCC were 0.879,0.887,0.801 and 0.939 for AFP,AFP-L3,PIVKA-Ⅱand the combined markers,respectively.The combined AUC for three markers showed higher value than the AUCs of individual marker(P<0.05).AFP-L3 had higher AUC value than PIVKA-Ⅱfor HCC detection in entire patients(P =0.043).With combination of AFP-L3(cut-off>5%) and PIVKA-Ⅱ(cut-off>40 AU/L),the sensitivity were 94.4%and specificity were 75.6%in all patients.In 112 patients with low AFP levels(<20 ng/mL),AUCs of AFP-L3,PIVKA-Ⅱand combine AFP-L3 and PIVKA-Ⅱtests were 0.824,0.774 and 0.939,respectively. AFP-L3 with a cut-off value of 5%showed sensitivity of 71.1%and specificity of 83.8%,and PIVKA-Ⅱwith a cut-off value of 40 AU/L had sensitivity of 57.9%and specificity of 95.9%in patients with low AFP levels. The combination of AFP-L3 and PIVKA-Ⅱincreased the sensitivity and specificity up to 92.1%and 79.7%, respectively,in low AFP group.Combined markers detected 81.8%of early stage HCC(Union for Inter-national Cancer Control stageⅠ),86.7%of small sized tumor(<2 cm)and 91.7%of single tumor of HCC in the low AFP group.In multivariate analysis,AFP-L3 was correlated with AFP and tumor size,and PIVKA-Ⅱwas correlated with laboratory tests including serum aspartate aminotransferase,total bilirubin,platelets and albumin levels.PIVKA-Ⅱhad no correlation with AFP,AFP-L3 or tumor characteristics. CONCLUSION:Combined determination of AFP-L3 and PIVKA-Ⅱcould improve the diagnostic value for HCC detection in patients with or without increased AFP levels. | Jong Young Choi Seung Won Jung Hee Yeon Kim Myungshin Kim Yonggoo Kim Dong Goo Kim Eun-Jee Oh | 2013 | World Journal of Gastroenterology2013，19，3： | 55 |
| 2 | Risk factors for complications associated with upper gastrointestinal foreign bodies显示文摘AIM: To investigate predictive risk factors associated with complications in the endoscopic removal of foreign bodies from the upper gastrointestinal tract.METHODS: We retrospectively reviewed the medical records of 194 patients with a diagnosis of foreign body impaction in the upper gastrointestinal tract,confirmed by endoscopy,at two university hospital in South Korea.Patient demographic data,including age,gender,intention to ingestion,symptoms at admission,and comorbidities,were collected.Clinical features of the foreign bodies,such as type,size,sharpness of edges,number,and location,were analyzed.Endoscopic data those were analyzed included duration of foreign body impaction,duration of endoscopic performance,endoscopic device,days of hospitalization,complication rate,30-d mortality rate,and the number of operationsrelated to foreign body removal.RESULTS: The types of upper gastrointestinal foreign bodies included fish bones,drugs,shells,meat,metal,and animal bones.The locations of impacted foreign bodies were the upper esophagus(57.2%),mid esophagus(28.4%),stomach(10.8%),and lower esophagus(3.6%).The median size of the foreign bodies was 26.2 ± 16.7 mm.Among 194 patients,endoscopic removal was achieved in 189,and complications developed in 51 patients(26.9%).Significant complications associated with foreign body impaction and removal included deep lacerations with minor bleeding(n = 31,16%),ulcer(n = 11,5.7%),perforation(n = 3,1.5%),and abscess(n = 1,0.5%).Four patients underwent operations because of incomplete endoscopic foreign body extraction.In multivariate analyses,risk factors for endoscopic complications and failure were sharpness(HR = 2.48,95%CI: 1.07-5.72; P = 0.034) and a greater than 12-h duration of impaction(HR = 2.42,95%CI: 1.12-5.25,P = 0.025).CONCLUSION: In cases of longer than 12 h since foreign body ingestion or sharp-pointed objects,rapid endoscopic intervention should be provided in patients with ingested foreign bodies. | Kyong Hee Hong Yoon Jae Kim Jae Hak Kim Song Wook Chun Hee Man Kim Jae Hee Cho | 2015 | World Journal of Gastroenterology2015，21，26： | 35 |
| 3 | Comparison of scoring systems in predicting the severity of acute pancreatitis显示文摘AIM:To investigate the prognostic usefulness of several existing scoring systems in predicting the severity of acute pancreatitis(AP).METHODS:We retrospectively analyzed the prospectively collected clinical database from consecutive patients with AP in our institution between January 2011 and December 2012.Ranson,Acute Physiology and Chronic Health Evaluation(APACHE)-Ⅱ,and bedside index for severity in acute pancreatitis(BISAP)scores,and computed tomography severity index(CTSI)of all patients were calculated.Serum C-reactive protein(CRP)levels were measured at admission(CRPi)and after 24h(CRP24).Severe AP was defined as persistent organ failure for more than 48 h.The predictive accuracy of each scoring system was measured by the area under the receiver-operating curve(AUC).RESULTS:Of 161 patients,21(13%)were classified as severe AP,and 3(1.9%)died.Statistically significant cutoff values for prediction of severe AP were Ranson≥3,BISAP≥2,APACHE-Ⅱ≥8,CTSI≥3,and CRP24≥21.4.AUCs for Ranson,BISAP,APACHE-Ⅱ,CTSI,and CRP24 in predicting severe AP were 0.69(95%CI:0.62-0.76),0.74(95%CI:0.66-0.80),0.78(95%CI:0.70-0.84),0.69(95%CI:0.61-0.76),and0.68(95%CI:0.57-0.78),respectively.APACHE-Ⅱdemonstrated the highest accuracy for prediction of severe AP,however,no statistically significant pairwise differences were observed between APACHE-Ⅱand the other scoring systems,including CRP24.CONCLUSION:Various scoring systems showed similar predictive accuracy for severity of AP.Unique models are needed in order to achieve further improvement of prognostic accuracy. | Joon Hyun Cho Tae Nyeun Kim Hyun Hee Chung Kook Hyun Kim | 2015 | World Journal of Gastroenterology2015，21，8： | 35 |
| 4 | 8-Hydroxydeoxyguanosine:Not mere biomarker for oxidative stress,but remedy for oxidative stress-implicated gastrointestinal diseases显示文摘Reactive oxygen species (ROS) attack guanine bases in DNA easily and form 8-hydroxydeoxyguanosine (8-OHdG),which can bind to thymidine rather than cytosine,based on which,the level of 8-OHdG is gen-erally regarded as a biomarker of mutagenesis conse-quent to oxidative stress.For example,higher levels of 8-OHdG are noted in Helicobacter pylori-associated chronic atrophic gastritis as well as gastric cancer.However,we have found that exogenous 8-OHdG can paradoxically reduce ROS production,attenuate thenuclear factor-κB signaling pathway,and ameliorate the expression of proinflammatory mediators such as interleukin (IL)-1,IL-6,cyclo-oxygenase-2,and induc-ible nitric oxide synthase in addition to expression of nicotinamide adenine dinucleotide phosphate oxidase (NOX)-1,NOX organizer-1 and NOX activator-1 in vari-ous conditions of inflammation-based gastrointestinal (GI) diseases including gastritis,inflammatory bowel disease,pancreatitis,and even colitis-associated carci-nogenesis.Our recent finding that exogenous 8-OHdG was very effective in either inflammation-based or oxidative-stress-associated diseases of stress-related mucosal damage has inspired the hope that synthetic 8-OHdG can be a potential candidate for the treatment of inflammation-based GI diseases,as well as the pre-vention of inflammation-associated GI cancer.In this editorial review,the novel fact that exogenous 8-OHdG can be a functional molecule regulating oxidative-stress-induced gastritis through either antagonizing Rac-guanosine triphosphate binding or blocking the signals responsible for gastric inflammatory cascade is introduced. | Chan-Young Ock Eun-Hee Kim Duck Joo Choi Ho Jae Lee Ki-Baik Hahm Myung Hee Chung | 2012 | World Journal of Gastroenterology2012，18，4： | 30 |

| 6 | 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 |
| 7 | Comparison of totally laparoscopic total gastrectomy using an endoscopic linear stapler with laparoscopic-assisted total gastrectomy using a circular stapler in patients with gastric cancer: a single-center experience显示文摘AIM To evaluate the safety and efficacy of totally laparoscopic total gastrectomy(TLTG) with esophagojejunostomy using a linear stapler compared with laparoscopic-assisted total gastrectomy(LATG) using a circular stapler in gastric cancer patients.METHODS We retrospectively reviewed 687 patients who underwent laparoscopic total gastrectomy for gastric cancer at a single institution from August 2008 to August 2014. The patients were divided into two groups according to the type of operation: 421 patients underwent TLTG and 266 underwent LATG. Clinicopathologic characteristics and surgical outcomes in the two groups were compared and analyzed.RESULTS The TLTG group had higher mean ages at the time of operation(57.78 ± 11.20 years and 55.69 ± 11.96 years,P = 0.020) and more histories of abdominal surgery(20.2% and 12.4%,P = 0.008) compared with the LATG group. Surgical outcomes such as intraoperative and postoperative transfusions,combined operations,pain scores and administration of analgesics,and complications were similar between the two groups. However,compared with the LATG group,the TLTG group required a shorter operation time(149 min vs 170 min,P < 0.001),had lower postoperative hematocrit change(3.49% vs 4.04%,P = 0.002),less intraoperative events(3.1% vs 10.2%,P < 0.001),less intraoperative anastomosis events(2.4% vs 7.1%,P = 0.003),faster postoperative recovery such as median time to first flatus(3.30 d vs 3.60 d,P < 0.001),faster median commencement of soft diet(4.30 d vs 4.60 d,P < 0.001) and shorter length of postoperative hospital stay(6.75 d vs 7.02 d,P = 0.005). CONCLUSION The intracorporeal method for reconstruction of esophagojejunostomy using a linear stapler may be considered a feasible procedure comparing with extracorporeal anastomosis using circular stapler because TLTG is simpler and more straightforward than LATG. Therefore,TLTG can be recommended as an appropriate procedure for gastric cancer. | Chung Sik Gong Byung Sik Kim Hee Sung Kim | 2017 | World Journal of Gastroenterology2017，23，48： | 23 |
| 8 | Sex-and gender-specific disparities in colorectal cancer risk显示文摘Colorectal cancer is one of the most common causes of cancer morbidity both in men and in women.However,females over 65 years old show higher mortality and lower 5-year survival rate of colorectal cancer compared to their age-matched male counterparts.The objective of this review is to suggest gender-based innovations to improve colorectal cancer outcomes in females.Women have a higher risk of developing right-sided(proximal) colon cancer than men,which is associated with more aggressive form of neoplasia compared to left-sided(distal) colon cancer.Despite differences in tumor location between women and men,most of scientific researchers do not consider sex specificity for study design and interpretation.Also,colorectal cancer screening guidelines do not distinguish females from male,which may explain the higher frequency of more advanced neoplasia when tumors are first detected and false negative results in colonoscopy in females.Moreover,socio-cultural barriers within females are present to delay screening and diagnosis.Few studies,among studies that included both men and women,have reported sex-specific estimates of dietary risk factors which are crucial to establish cancer prevention guidelines despite sex-and genderassociated differences in nutrient metabolism and dietary practices.Furthermore,anti-cancer drug use for colorectal cancer treatment can cause toxicity to the reproductive system,and gender-specific recurrence and survival rates are reported.Therefore,by understanding sex-and gender-related biological and socio-cultural differences in colorectal cancer risk,gender-specific strategies for screening,treatment and prevention protocols can be established to reduce the mortality and improve the quality of life. | Sung-Eun Kim Hee Young Paik Hyuk Yoon Jung Eun Lee Nayoung Kim Mi-Kyung Sung | 2015 | World Journal of Gastroenterology2015，21，17： | 18 |
| 9 | Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence. | Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh | 2010 | World Journal of Gastroenterology2010，16，22： | 17 |
| 10 | The association of benign prostatic hyperplasia with lower urinary tract stones in adult men: A retrospective multicenter study显示文摘Objective:To examine the relationship between benign prostatic hyperplasia(BPH)and the presence of lower urinary tract stones.Methods:We retrospectively reviewed the records of men with lower urinary tract stones who presented to three clinical centers in Korea over a 4-year period.We divided the patients into two groups based on the location of urinary stones:Group 1(bladder calculi)and Group 2(urethral calculi).We compared the characteristics of both groups and performed univariate and multivariate analyses with a logistic regression model to investigate the relationship between BPH and lower urinary tract stones.Results:Of 221 patients,194(87.8%)had bladder calculi and 27(12.2%)had urethral calculi.The mean age of Group 1 was higher than that of Group 2(68.9612.11 years vs.55.7414.20 years,p<0.001).The mean prostate volume of Group 1 was higher than that of Group 2(44.4727.14 mL vs.24.706.41 mL,respectively,p<0.001).Multivariate logistic regression showed that age(OR Z 1.075,95%CI:1.023e1.129)and prostate volume(OR Z 1.069,95%CI:1.017e1.123)were independently associated with increased risk for bladder calculi.Upper urinary tract stones and/or hydronephrosis conferred a 3-fold risk for urethral calculi(OR Z 3.468,95%CI:1.093e10.999).Conclusion:Age and prostate volume are independent risk factors for bladder calculi.In addition,men with upper urinary tract disease are at greater risk for urethral calculi,which may migrate from the upper urinary tract rather than from the bladder. | Jae Hung Jung Jinsung Park Won Tae Kim Hong Wook Kim Hyung Joon Kim Sungwoo Hong Hee Jo Yang Hong Chung | 2018 | Asian Journal of Urology2018，5，2： | 17 |
| 11 | Multimodal imaging evaluation in staging of rectal cancer显示文摘Rectal cancer is a common cancer and a major cause of mortality in Western countries.Accurate staging is essential for determining the optimal treatment strategies and planning appropriate surgical procedures to control rectal cancer.Endorectal ultrasonography(EUS)is suitable for assessing the extent of tumor invasion,particularly in early-stage or superficial rectal cancer cases.In advanced cases with distant metastases,computed tomography(CT)is the primary approach used to evaluate the disease.Magnetic resonance imaging(MRI)is often used to assess preoperative staging and the circumferential resection margin involvement,which assists in evaluating a patient’s risk of recurrence and their optimal therapeutic strategy.Positron emission tomography(PET)-CT may be useful in detecting occult synchronous tumors or metastases at the time of initial presentation.Restaging after neoadjuvant chemoradiotherapy(CRT)remains a challenge with all modalities because it is difficult to reliably differentiate between the tumor mass and other radiation-induced changes in the images.EUS does not appear to have a useful role in post-therapeutic response assessments.Although CT is most commonly used to evaluate treatment responses,its utility for identifying and following-up metastatic lesions is limited.Preoperative high-resolution MRI in combination with diffusion-weighted imaging,and/or PET-CT could provide valuable prognostic information for rectal cancer patients with locally advanced disease receiving preoperative CRT.Based on these results,we conclude that a combination of multimodal imaging methods should be used to precisely assess the restaging of rectal cancer following CRT. | Suk Hee Heo Jin Woong Kim Sang Soo Shin Yong Yeon Jeong Heoung-Keun Kang | 2014 | World Journal of Gastroenterology2014，20，15： | 16 |

| 13 | Clinical characteristics and treatment of inflammatory bowel disease: A comparison of Eastern and Western perspectives显示文摘Inflammatory bowel disease(IBD) is a chronic, relapsing intestinal inflammatory disorder with unidentified causes. Both environmental factors and genetic aspects are believed to be crucial to the pathogenesis of IBD. The incidence and prevalence of IBD have recently been increasing throughout Asia, presumably secondary to environmental changes. This increasing trend in IBD epidemiology necessitates specific health care planning and education in Asia. To this end, we must gain a precise understanding of the distinctive clinical and therapeutic characteristics of Asian patients with IBD. The phenotypes of IBD reportedly differ considerably between Asians and Caucasians. Thus, use of the same management strategies for these different populations may not be appropriate. Moreover, investigation of the Asian-specific clinical aspects of IBD offers the possibility of identifying causative factors in the pathogenesis of IBD in this geographical area. Accordingly, this review summarizes current knowledge of the phenotypic manifestations and management practices of patients with IBD, with a special focus on a comparisonof Eastern and Western perspectives. | Soo Jung Park Won Ho Kim Jae Hee Cheon | 2014 | World Journal of Gastroenterology2014，20，33： | 15 |
| 14 | 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 |
| 15 | Use of a clinical pathway in laparoscopic gastrectomy for gastric cancer显示文摘AIM: To evaluate the implementation of a clinical pathway and identify clinical factors affecting the clinical pathway for laparoscopic gastrectomy.METHODS: A standardized clinical pathway for gastric cancer(GC) patients was developed in 2001 by the GC surgery team at the Asan Medical Center. We reviewed the collected data of 4800 consecutive patients treated using the clinical pathway following laparoscopic gastrectomy with lymph node dissection for GC involving intracorporeal and extracorporeal anastomosis. The patients were treated between August 2004 and October 2013 in a single institution. To evaluate the rate of completion and risk factors affecting dropout from the clinical pathway, we used a multivariate logistic regression analysis.RESULTS: The overall completion rate of the clinical pathway for laparoscopic gastrectomy was 84.1%(n = 4038). In the comparison between groups of intracorporeal anastomosis and extracorporeal anastomosis patients, the completion rates were 8 3. 8 8 %(n = 1 7 4 0) a n d 8 4. 3 6 %(n = 2 0 7 1), respectively, showing no statistically significant difference. The main reasons for dropping out were postoperative complications(n = 463, 9.7%) and the need for patient observation(n = 299, 6.2%). Among the discharged patients treated using the clinical pathway, the number of patients who were readmitted within 30 d due to postoperative complications was 54(1.1%). In a multivariate analysis, the intraoperative events(OR = 2.558) were the most predictable risk factors for dropping out of the clinical pathway. Additionally, being male(OR = 1.459), advanced age(OR = 1.727), total gastrectomy(OR = 2.444), combined operation(OR = 1.731), and ASA score(OR = 1.889) were significant risk factors affecting the dropout rate from the clinical pathway.CONCLUSION: Laparoscopic gastrectomy appears to be a good indication for the application of a clinical pathway. For successful application, patients with risk factors should be managed carefully. | Hee Sung Kim Sun Oak Kim Byung Sik Kim | 2015 | World Journal of Gastroenterology2015，21，48： | 15 |
| 16 | Change in subfoveal choroidal thickness after argon laser panretinal photocoagulation显示文摘AIM:To evaluate changes in subfoveal choroidal thickness(SFCT) and macular thickness as measured by enhanced depth imaging spectral-domain optical coherence tomography(EDI-OCT) after argon laser panretinal photocoagulation(PRP) in patients with severe diabetic retinopathy.·METHODS:This prospective,comparative case series included 21 patients(28 eyes) with severe diabetic retinopathy.All patients underwent three sessions of PRP.The SFCT and macular thickness were measured using EDI-OCT at baseline and one week after completion of 3 sessions of PRP.·RESULTS:SFCT before PRP was(318.1±96.5)μm and increased to(349.9 ±108.3)μm(P =0.001) after PRP.Macular thickness significantly increased at one week after PRP(from 273.1 ±23.9μm at baseline vs 295.8 ±25.3μm at one week;P <0.001).No significant relationship between the changes in macular thickness and SFCT was observed(r =-0.13,P =0.52).·CONCLUSION:PRP induced increases in both SFCT and macular thickness.Changes in SFCT did not correlate with changes in macular thickness. | Ga Eun Cho Hee Yun Cho Yun Taek Kim | 2013 | International Journal of Ophthalmology(English edition)2013，6，4： | 14 |
| 17 | Colonoscopy evaluation after short-term anti-tuberculosis treatment in nonspecific ulcers on the ileocecal area显示文摘AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the 'suspicious tuberculous colitis group' showing healing of ulcers and erosions and another is the 'suspicious inflammatory bowel disease group' showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the 'suspicious tuberculous colitis group' were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the 'suspicious inflammatorybowel disease group' were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis. | Young Sook Park Dae Won Jun Seong Hwan Kim Han Hyo Lee Yun Ju Jo Moon Hee Song Nam In Kim Jun Seok Lee | 2008 | World Journal of Gastroenterology2008，14，32： | 14 |
| 18 | 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 |
| 19 | 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 |
