| 1 | Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy显示文摘AIM:To compare small sphincterotomy combined with endoscopic papillary large balloon dilation(SES+ ELBD)and endoscopic sphincterotomy(EST)for large bile duct stones. METHODS:We compared prospectively SES+ELBD (group A,n=27)with conventional EST(group B, n=28)for the treatment of large bile duct stones(≥ 15 mm).When the stone could not be removed with a normal basket,mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS:No significant differences were observed in the mean largest stone size(A:20.8 mm,B:21.3 mm), bile duct diameter(A:21.4 mm,B:20.5 mm),number of stones(A:2.2,B:2.3),or procedure time(A:18 min, B:19 min)between the two groups.The rates of complete stone removal with one session was 85%in group A and 86%in group B(P=0.473).Mechanical lithotripsy was required for stone removal in nine of 27 patients(33%)in group A and nine of 28 patients (32%,P=0.527)in group B.CONCLUSION:SES+ELBD did not show significant benefits compared to conventional EST,especially for the removal of large(≥15 mm)bile duct stones. | Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun Park Tae Hoon Lee Hyun Jong Choi Sang-Heum Park Joon Seong Lee Moon Sung Lee | 2009 | World Journal of Gastroenterology2009，15，34： | 34 |
| 2 | Management of the complications of endoscopic submucosal dissection显示文摘Endoscopic submucosal dissection(ESD) is currently widely accepted as a standard treatment option for early gastrointestinal neoplasms in Korea.However,ESD has technical difficulties and a longer procedure time than conventional endoscopic resection.So it may have a higher risk of complications than conventional endoscopic resection techniques.We,the ESD study group of Korean Society of Gastrointestinal Endoscopy,have experienced many complications,mostly treated by endoscopic or conservative management.Here,we introduce and share our experiences for managementof post ESD complications and review published papers on the topic. | Seong Hwan Kim Jeong Seop Moon Young Hoon Youn Ki Myung Lee Sung Joon Lee | 2011 | World Journal of Gastroenterology2011，17，31： | 19 |
| 3 | Clinical significance of CT-defined minimal ascites in patients with gastric cancer显示文摘AIM: To study the clinical significance of minimal ascites,which was only defined by the CT and whose nature was not determined preoperatively, in the relationship with the peritoneal carcinomatosis.METHODS: The medical records and the dynamic CT films of 118 patients with gastric cancer were reviewed.Factors associated with peritoneal carcinomatosis were analyzed in 40 patients who had CT-defined ascites of which the nature was surgically confirmed.RESULTS: Only 12.5-25% of the CT-defined minimal ascites, whose volume was estimated to be less than 50 mL, were associated with peritoneal carcinomatosis.When the estimated CT-defined ascitic volume was 50 mL or more, peritoneal carcinomatosis was identified in 75-100%. When CT-defined lymph node enlargements were not found beyond the regional gastric area,perigastricinvasions were not suspected, and the size of tumor was less than 3 cm, peritoneal carcinomatosis seemed significantly less accompanied at the univariate analysis. However, except for the minimal volume of CTdefined ascites in comparison with the mild or more,other factors were not confirmed multivariately.CONCLUSION: In the patients with gastric cancer, CTdefined minimal ascites alone is rarely associated with peritoneal carcinomatosis, if it does not accompany other signs suggestive of malignant seeding. Therefore,consideration of active curative resection should not be hesitated, if CT-defined minimal ascites is the only delusive sign. | Dong Kyung Chang Ji Won Kim Byung Kwan Kim Kook Lae Lee Chi Sung Song Joon Koo Han In Sung Song | 2005 | World Journal of Gastroenterology2005，11，42： | 14 |

| 5 | Durability of viral response after off-treatment in HBeAg positive chronic hepatitis B显示文摘AIM:To evaluate the durability in hepatitis B e antigen (HBeAg) positive chronic hepatitis B patients who discontinued antiviral treatment. METHODS:A total of 48 HBeAg positive chronic hepatitis B patients who were administered nucleoside analogues and maintained virological response for ≥ 6 mo [hepatitis B virus (HBV) DNA < 300 copies/mL and HBeAg seroconversion] before cessation of treatment were enrolled between February 2007 and January 2010. The criteria for the cessation of the antiviral treatment were defined as follows:(1) achievement of virological response; and (2) duration of consolidation therapy (≥ 6 mo). After treatment cessation, the patients were followed up at 3-6 mo intervals. The primary endpoint was serologic and virologic recurrence rates after withdrawal of antiviral treatment. Serologic recurrence was defined as reappearance of HBeAg positivity after HBeAg seroconversion. Virologic recurrence was defined as an increase in HBV-DNA level > 104 copies/mL after HBeAg seroconversion with previously undetectable HBV-DNA level. RESULTS:During the median follow-up period of 18.2 mo (range:5.1-47.5 mo) after cessation of antiviral treatment, the cumulative serological recurrence rate was 15 % at 12 mo. The median duration between the cessation of antiviral treatment and serologic recurrence was 7.2 mo (range:1.2-10.9 mo). Of the 48 patients with HBeAg positive chronic hepatitis, 20 (41.6%) showed virological recurrence. The cumulative virologic recurrence rates at 12 mo after discontinuing the antiviral agent were 41%. The median duration between off-treatment and virologic recurrence was 7.6 mo (range:4.3-27.1 mo). The mean age of the virological recurrence group was older than that of the non-recurrence group (46.7 ± 12.1 years vs 38.8 ± 12.7 years, respectively; P = 0.022). Age (> 40 years) and the duration of consolidation treatment (≥ 15 mo) were significant predictive factors for offtreatment durability in the multivariate analysis [P = 0.049, relative risk (RR) 0.31, 95% CI (0.096-0.998) and P = 0.005, RR 11.29, 95% CI (2.054-65.12), respectively]. Patients with age (≤ 40 years) who received consolidation treatment (≥ 15 mo) significantly showed durability in HBeAg positive chronic hepatitis B patients (P = 0.014). These results suggest that additional treatment for more than 15 mo after HBeAg seroconversion in patients who are ≤ 40 years old may be beneficial in providing a sustained virological response. CONCLUSION:Our data suggest that HBeAg seroconversion is an imperfect end point in antiviral treatment. Long-term consolidation treatment (≥ 15 mo) in younger patients is important for producing better prognosis in HBeAg positive chronic hepatitis B. | Myeong Jun Song Do Seon Song Hee Yeon Kim Sun Hong Yoo Si Hyun Bae Jong Young Choi Seung Kew Yoon Yong-Han Paik June Sung Lee Hyun Woong Lee Hyung Joon Kim | 2012 | World Journal of Gastroenterology2012，18，43： | 7 |
| 6 | Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC. | Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon | 2015 | World Journal of Gastroenterology2015，21，8： | 7 |
| 7 | Is the AIM65 score useful in predicting outcomes in peptic ulcer bleeding?显示文摘AIM:To evaluate the applicability of AIMS65 scores in predicting outcomes of peptic ulcer bleeding.METHODS:This was a retrospective study in a single center between January 2006 and December 2011.We enrolled 522 patients with upper gastrointestinal haemorrhage who visited the emergency room.Highrisk patients were regarded as those who had rebleeding within 30 d from the first endoscopy as well as those who died within 30 d of visiting the Emergency room.A total of 149 patients with peptic ulcer bleeding were analysed,and the AIMS65 score was used to retrospectively predict the high-risk patients.RESULTS:A total of 149 patients with peptic ulcer bleeding were analysed.The poor outcome group comprised 28 patients[male:23(82.1%)vs female:5(10.7%)]while the good outcome group included 121patients[male:93(76.9%)vs female:28(23.1%)].The mean age in each group was not significantly different.The mean serum albumin levels in the poor outcome group were slightly lower than those in the good outcome group(P=0.072).For the prediction of poor outcome,the AIMS65 score had a sensitivity of35.5%(95%CI:27.0-44.8)and a specificity of 82.1%(95%CI:63.1-93.9)at a score of 0.The AIMS65 score was insufficient for predicting outcomes in peptic ulcer bleeding(area under curve=0.571;95%CI:0.49-0.65).CONCLUSION:The AIMS65 score may therefore not be suitable for predicting clinical outcomes in peptic ulcer bleeding.Low albumin levels may be a risk factor associated with high mortality in peptic ulcer bleeding. | Sung Hoon Jung Jung Hwan Oh Hye Yeon Lee Joon Won Jeong Se Eun Go Chan Ran You Eun Jung Jeon Sang Wook Choi | 2014 | World Journal of Gastroenterology2014，20，7： | 6 |
| 8 | Assessment of scoring systems for acute-on-chronic liver failure at predicting short-term mortality in patients with alcoholic hepatitis显示文摘AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic hepatitis.METHODS We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis. | Hee Yeon Kim Chang Wook Kim Tae Yeob Kim Do Seon Song Dong Hyun Sinn Eileen L Yoon Young Kul Jung Ki Tae Suk Sang Soo Lee Chang Hyeong Lee Tae Hun Kim Jeong Han Kim Hyung Joon Yim Sung Eun Kim Soon Koo Baik Byung Seok Lee Jae Young Jang Young Seok Kim Sang Gyune Kim Jin Mo Yang Joo Hyun Sohn Heon Ju Lee Seung Ha Park Eun Hee Choi Dong Joon Kim Korean Acute-on-Chronic Liver Failure Study Group | 2016 | World Journal of Gastroenterology2016，22，41： | 5 |
| 9 | Hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To evaluate the prognostic factors and efficacy of hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis. METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m 2 epirubicin on day 1, 60 mg/m 2 cisplatin for 2 h on day 2, and 500 mg/m 2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk. RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD).The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm 3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-Ⅱ (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed. CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm 3 and good prognostic factors. | Do Seon Song Si Hyun Bae Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Jung Suk Oh Ho Jong Chun Hae Giu Lee Jong Young Choi Seung Kew Yoon | 2013 | World Journal of Gastroenterology2013，19，29： | 5 |
| 10 | Nonalcoholic fatty liver disease is associated with coronary artery disease in Koreans显示文摘AIM:To investigate whether nonalcoholic fatty liver disease(NAFLD)affects coronary artery disease(CAD)and identify candidate mediators.METHODS:Patients who underwent coronary angiography were consecutively recruited.The patients were classified into four groups by coronary artery stenosis:A,insignificant;B,one-vessel disease;C,two-vessel disease;and D,three-vessel disease.Abdominal ultrasonography was performed to determine the presence of a fatty liver and categorize by grade:0,no evidence;1,mild;2,moderate;and 3,severe.We measured not only known CAD risk factors,but also serum insulin,HOMA-index,adiponectin,interleukin-6,tumor necrosis factor-αand high-sensitivity C-reactive protein levels.RESULTS:Of the 134 patients who met the inclusion criteria,82(61.2%)had ultrasonographically diagnosed NAFLD.Among the 46 patients with CAD,37(80.4%)had evidence of a fatty liver.The two groups(A vs B-D)were significantly different in terms of age,total cholesterol,triglycerides,low-density lipoprotein levels and fatty liver.Coronary artery stenosis was strongly associated with fatty liver in a grade-dependent manner(P=0.025).In binary logistic regression,NAFLD was a significant independent predictor of CAD(P=0.03,OR=1.685;95%CI:1.051-2.702).Among the candidate mediators,the serum adiponectin level showed a trend toward lowering based on CAD progression(P=0.071).CONCLUSION:NAFLD is an independent risk factor for CAD in a grade-dependent manner.Moreover,adiponectin might be related to the pathogenesis of NAFLD. | Dae Hee Choi Sung Joon Lee Chang Don Kang Myoung Ok Park Dong Wook Choi Tae Suk Kim Wonho Lee Byung Ryul Cho Yong Hoon Kim Bong-ki Lee Dong Ryeol Ryu Ji Won Lee | 2013 | World Journal of Gastroenterology2013，19，38： | 5 |

| 13 | Milan criteria are useful predictors for favorable outcomes in hepatocellular carcinoma patients undergoing liver transplantation after transarterial chemoembolization显示文摘AIM: To evaluate whether the Milan criteria are useful in patients with hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE) before liver transplantation (LT). METHODS: Thirty-six HCC patients who fulfilled the Milan criteria after having received TACE and subsequently underwent LT were included (TACE + LT group) in the study. As controls, 21 patients who also met the Milan criteria and underwent LT without prior treatment were selected (LT group). Post-LT clinical outcomes, such as HCC recurrence, survival rate, and histologic features of explanted livers, were compared between the two groups. RESULTS: Baseline characteristics were not different between the two groups. Pre-LT maximal tumor diameter in TACE + LT group was similar to that of LT group (2.0 ± 0.6 cm vs 2.3 ± 0.9 cm; P = 0.10). Post-LT histologic findings also revealed similar maximal tumor diameter in the two groups (2.4 ± 1.4 cm vs 2.3 ± 0.9 cm; P = 0.70). Explanted livers showed similar incidence of unfavorable pathologic features. The morality within 60 d after transplantation was not different between the two groups (8.3% vs 9.5%; P = 0.99). Post-LT 5-year survival rate (57% vs 74%; P = 0.70) and cumulative recurrence rate (8.3% vs 4.8%; P = 0.90) were not significantly different between the two groups. CONCLUSION: The Milan criteria are still a useful selec- tion criteria showing favorable outcomes in HCC patientsreceiving TACE before LT. | Do Young Kim Moon Seok Choi Joon Hyoek Lee Kwang Cheol Koh Seung Woon Paik Byung Chul Yoo Sung Wook Shin Sung Wook Choo Young Soo Do Jong Chul Rhee | 2006 | World Journal of Gastroenterology2006，12，43： | 4 |

| 15 | Differentiation of acute and chronic hepatitis B in IgM antiHBc positive patients显示文摘AIM: To identify the factors that differentiate acute hepatitis B(AHB) from chronic hepatitis B with acute exacerbation(CHB-AE).METHODS: From 2004 to 2013, a total of 82 patients(male n = 52, 63.4%; female n = 30, 36.6%) with clinical features of acute hepatitis with immunoglobulin M antibodies to the hepatitis B core antigen(Ig M antiHBc) were retrospectively enrolled and divided into two groups; AHB(n = 53) and CHB-AE(n = 29). The AHB group was defined as patients without a history of hepatitis B virus(HBV) infection before the episode and with loss of hepatitis B surface antigen within 6 mo after onset of acute hepatitis. Biochemical and virological profiles and the sample/cutoff(S/CO) ratio of Ig M anti-HBc were compared to determine the differential diagnostic factors.RESULTS: The multivariate analysis demonstrated that, the S/CO ratio of Ig M anti-HBc and HBV DNA levels were meaningful factors. The S/CO ratio of Ig M anti-HBc was significantly higher in the AHB group, while the HBV DNA level was significantly higher in the CHB-AE group. The optimal cutoff values of Ig M anti-HBc and HBV DNA levels for differentiating the two conditions were 8 S/CO ratio and 5.5 log10 IU/m L, respectively. The sensitivity and specificity were 96.2% and 89.7% for the S/CO ratio of Ig M anti-HBc and 81.1% and 72.4% for HBV DNA levels, respectively. The area under receiver operating characteristic curves of both the S/CO ratio of Ig M anti-HBc and HBV DNA levels were not significantly different(0.933 vs 0.844, P = 0.105). When combining Ig M anti-HBc and HBV DNA, the diagnostic power significantly improved compared to HBV DNA alone(P = 0.0056). The combination of these factors yielded a sensitivity and specificity of 98.1% and 86.2%, respectively.CONCLUSION: The combination of the S/CO ratio of Ig M anti-HBc and HBV DNA levels was a useful tool for differentiating AHB from CHB-AE in patients with positive Ig M anti-HBc. | Ji Won Park Kyeong Min Kwak Sung Eun Kim Myoung Kuk Jang Dong Joon Kim Myung Seok Lee Hyoung Su Kim Choong Kee Park | 2015 | World Journal of Gastroenterology2015，21，13： | 4 |

| 17 | Glucose metabolism and neurogenesis in the gerbil hippocampus after transient forebrain ischemia显示文摘Recent evidence exists that glucose transporter 3(GLUT3) plays an important role in the energy metabolism in the brain.Most previous studies have been conducted using focal or hypoxic ischemia models and have focused on changes in GLUT3 expression based on protein and m RNA levels rather than tissue levels.In the present study,we observed change in GLUT3 immunoreactivity in the adult gerbil hippocampus at various time points after 5 minutes of transient forebrain ischemia.In the sham-operated group,GLUT3 immunoreactivity in the hippocampal CA1 region was weak,in the pyramidal cells of the CA1 region increased in a time-dependent fashion 24 hours after ischemia,and in the hippocampal CA1 region decreased significantly between 2 and 5 days after ischemia,with high level of GLUT3 immunoreactivity observed in the CA1 region 10 days after ischemia.In a double immunofluorescence study using GLUT3 and glial-fibrillary acidic protein(GFAP),we observed strong GLUT3 immunoreactivity in the astrocytes.GLUT3 immunoreactivity increased after ischemia and peaked 7 days in the dentate gyrus after ischemia/reperfusion.In a double immunofluorescence study using GLUT3 and doublecortin(DCX),we observed low level of GLUT3 immunoreactivity in the differentiated neuroblasts of the subgranular zone of the dentate gyrus after ischemia.GLUT3 immunoreactivity in the sham-operated group was mainly detected in the subgranular zone of the dentate gyrus.These results suggest that the increase in GLUT3 immunoreactivity may be a compensatory mechanism to modulate glucose level in the hippocampal CA1 region and to promote adult neurogenesis in the dentate gyrus. | Dae Young Yoo Kwon Young Lee Joon Ha Park Hyo Young Jung Jong Whi Kim Yeo Sung Yoon Moo-Ho Won Jung Hoon Choi In Koo Hwang | 2016 | Neural Regeneration Research2016，11，8： | 4 |
| 18 | Simplified fistula dilation technique and modified stent deployment maneuver for EUS-guided hepaticogastrostomy显示文摘AIM:To evaluate the success rates,procedural time and adverse event rates of the modified methods in endoscopic ultrasonography-guided hepaticogastrostomy(EUS-HGS).METHODS:Twenty-eight patients in a prospective case series who underwent EUS-HGS(phaseⅠ).Fortysix patients in a matched case-control study(phaseⅡ).The simplified technique for fistula dilation was the primary use of a 4 mm balloon catheter with a stainless steel stylet.The stent deployment was modified by deploying the metal stent inside a bile duct(half of the stent)under EUS and fluoroscopic guidance and gently pulling the echoendoscope after full deployment of the stent inside the echoendoscope channel(remaining portion of the stent)under fluoroscopic guidance.This cohort was compared with a matched historical cohort.RESULTS:In phaseⅠ,the technical and clinical success with the modified method was 96%(27/28)and89%(24/27 as per-protocol analysis).The overall adverse event rate was 7%.In phaseⅡ,there was no difference in technical and clinical success,stent patency and overall adverse events in each group.However,the procedural time(15.3±5.2 min vs 22.3±6.0 min,P<0.001)and early adverse events(0%vs 26%,P=0.02)were statistically improved in case cohort compared with control cohort.CONCLUSION:Compared with the conventional EUSHGS technique,the procedural time was shorter and early adverse events were less frequent with our simplified and modified technique. | Woo Hyun Paik Do Hyun Park Jun-Ho Choi Joon Hyuk Choi Sang Soo Lee Dong Wan Seo Sung Koo Lee Myung-Hwan Kim Jung Bok Lee | 2014 | World Journal of Gastroenterology2014，20，17： | 4 |

| 20 | Diagnostic delay in inflammatory bowel disease increases the risk of intestinal surgery显示文摘AIM To investigate the factors affecting diagnostic delay and outcomes of diagnostic delay in inflammatory bowel disease(IBD) METHODS We retrospectively studied 165 patients with Crohn's disease(CD) and 130 patients with ulcerative colitis(UC) who were diagnosed and had follow up durations > 6 mo at Korea University Ansan Hospital from January 2000 to December 2015. A diagnostic delay was defined as the time interval between the first symptom onset and IBD diagnosis in which the 76^(th) to 100^(th) percentiles of patients were diagnosed.RESULTS The median diagnostic time interval was 6.2 and 2.4 mo in the patients with CD and UC, respectively. Among the initial symptoms, perianal discomfort before diagnosis(OR = 10.2, 95%CI: 1.93-54.3, P = 0.006) was associated with diagnostic delays in patients with CD; however, no clinical factor was associated with diagnostic delays in patients with UC. Diagnostic delays, stricturing type, and penetrating type were associated with increased intestinal surgery risks in CD(OR = 2.54, 95%CI: 1.06-6.09; OR = 4.44, 95%CI: 1.67-11.8; OR = 3.79, 95%CI: 1.14-12.6, respectively). In UC, a diagnostic delay was the only factor associated increased intestinal surgery risks(OR = 6.81, 95%CI: 1.12-41.4).CONCLUSION A diagnostic delay was associated with poor outcomes, such as increased intestinal surgery risks in patients with CD and UC. | Dong-won Lee Ja Seol Koo Jung Wan Choe Sang Jun Suh Seung Young Kim Jong Jin Hyun Sung Woo Jung Young Kul Jung Hyung Joon Yim Sang Woo Lee | 2017 | World Journal of Gastroenterology2017，23，35： | 3 |
