| 1 | Pre-operative factors that can predict neoplastic polypoid lesions of the gallbladder显示文摘AIM:To investigate the preoperative factors that can predict neoplastic polypoid lesions of the gallbladder(PLGs) as well as malignant PLGs.METHODS:A retrospective analysis was conducted on the 210 consecutively enrolled patients who underwent cholecystectomy due to a PLG larger than 10 mm,as was determined by preoperative trans-abdominal ultrasonography or endoscopic ultrasonography.We ana-lyzed the medical,laboratory,radiologic data and the pathologic results.RESULTS:In 210 cases,146 had non-neoplastic polyps(69.5%) and 64 cases were neoplastic polyps(30.5%).An older age(≥ 65 years),the presence of diabetes mellitus(DM) and the size of polyp(≥ 15 mm) were revealed to be independent predictive variables for neoplastic polyps with odd ratios(OR) of 2.27(P = 0.044),2.64(P = 0.021) and 4.94(P < 0.01),respectively.Among the neoplastic PLGs,an older age(≥ 65 years),the presence of DM and polyp size(≥ 15 mm) were associated with malignancy with ORs of 4.97(P = 0.005),6.13(P = 0.001) and 20.55(P < 0.001),respectively.CONCLUSION:Among patients with PLGs larger than 10 mm in size,higher risk groups such as elderly patients more than 65 years old,those with DM or a large polyp size(≥ 15 mm) should be managed by cholecystectomy. | Byung Hyo Cha Jin-Hyeok Hwang Sang Hyub Lee Jang Eon Kim Jai Young Cho Haeryoung Kim So Yeon Kim | 2011 | World Journal of Gastroenterology2011，17，17： | 27 |
| 2 | Spider angiomas in patients with liver cirrhosis: Role of vascular endothelial growth factor and basic fibroblast growth factor显示文摘AIM: To investigate whether vascular endothelial growth factor (VEGF) and basic fibroblastic growth factor (bFGF) are associated wibh spider angiomas in patients wibh liver cirrhosis. METHODS: Eighty-six patients with liver cirrhosis were enrolled and the number and size of the spider angiomas were recorded. Fifty-three healthy subjects were selected as controls. Plasma levels of VEGF and bFGF were measured in both the cirrhotics and the controls. RESULTS: Plasma VEGF and bFGF were increased in cirrhotics compared with controls (122±13 vs. 71±11 pg/mL, P=0.003 for VEGF; 5.1±0.5 vs. 3.4±0.5 pg/mL, P=0.022 for bFGF). In cirrhotics, plasma VEGF and bFGF were also higher in patients with spider angiomas compared with patients without spider angiomas (185±28 vs. 90±10 pg/mL, P=-0.003 for VEGF; 6.8±1.0 vs. 4.1±0.5 pg/mL, P=0.017 for bFGF). Multivariate logistic regression showed that young age and increased plasma levels of VEGF and bFGF were the most significant predictors for the presence of spider angiomas in cirrhotic patients (odds ratio [OR]=6.64, 95% confidence interval[CI]=2.02-21.79, P=0.002; OR=4.35, 95% CI=1.35-14.01,P=0.014; OR=5.66, 95% CI=1.72-18.63, P=0.004, respectively). CONCLUSION: Plasma VEGF and bFGF are elevated inpatients with liver cirrhosis. Age as well as plasma levels of VEGF and bFGF are significant predictors for spider angiomas in cirrhotic patients. | Chun-Pin Li Fa-Yauh Lee Shinn-Jang Hwang Rei-Hwa Lu Wei-Ping Lee Yee Chao Sung-Sang Wang Full-Young Chang Jacqueline Whang-Peng Shou-Dong Lee | 2003 | World Journal of Gastroenterology2003，9，12： | 24 |

| 5 | Biliary drainage for obstructive jaundice caused by unresectable hepatocellular carcinoma: the endoscopic versus percutaneous approach显示文摘BACKGROUND: For palliative treatment of the obstructive jaundice associated with unresectable hepatocellular carcinoma (HCC), percutaneous transhepatic biliary drainage (PTBD) or endoscopic retrograde biliary drainage (ERBD) has been performed. PTBD is preferred as an initial procedure. Little is known about the better option for patients with obstructive jaundice caused by unresectable HCC. METHODS: Sixty patients who had received ERBD or PTBD for the palliative treatment of obstructive jaundice caused by unresectable HCC between January 2006 and May 2010 were included in this retrospective study. Successful drainage, drainage patency, and the overall survival of patients were evaluated. RESULTS: Univariate analysis revealed that the overall frequency of successful drainage was higher in the ERBD group (22/29, 75.9%) than in the PTBD group (15/31, 48.4%) (P=0.029); but multivariate analysis showed marginal significance (P=0.057). The duration of drainage patency was longer in the ERBD group than in the PTBD group (82 vs 37 days, respectively, P=0.020). Regardless of what procedure was performed, the median survival time of patients who had a successful drainage was much longer than that of the patients who did not have a successful drainage (143 vs 38 days, respectively, P<0.001).CONCLUSION: Besides PTBD, ERBD may be used as the initial treatment option to improve obstructive jaundice in patients with unresectable HCC if there is a longer duration of drainage patency after a successful drainage. | Jongkyoung Choi Ji Kon Ryu Sang Hyub Lee Dong-Won Ahn Jin-Hyeok Hwang Yong-Tae Kim Yong Bum Yoon Joon Koo Han | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，6： | 17 |

| 7 | 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 |
| 8 | Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection显示文摘AIM:To evaluate the incidence and clinical characteristics of gastric cancer(GC) in peptic ulcer patients with Helicobacter pylori(H.pylori) infection.METHODS:Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed.Those with previous gastric ulcer(GU) and H.pylori infection were assigned to the Hp GU-GC group(n = 86) and those with previous duodenal ulcer(DU) disease and H.pylori infection were assigned to the Hp DUGC group(n = 35).The incidence rates of GC in the Hp GU-GC and Hp DU-GC groups were analyzed.Data on demographics(age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren's classification, atrophy of surrounding mucosa and intestinal metaplasia(IM)], outcome of eradication therapy for H.pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed.Univariate and multivariate analyses were performed to identify factors influencing GC development.The relative risk of GC was evaluated using a Cox proportional hazards model.RESULTS:The incidence rates of GC were 3.60%(86/2387) in the Hp GU-GC group and 1.66%(35/2098) in the Hp DU-GC group.The annual incidence was 0.41% in the Hp GU-GC group and 0.11% in the Hp DUGC group.The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the Hp GU-GC group than in the Hp DU-GC group(86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05).In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H.pylori infection were significantly associated with the development of GC(P < 0.05).There was no significant difference in the prognosis of GC patients between the Hp GU-GC and Hp DU-GC groups(P = 0.347).The relative risk of GC development in the Hp GUGC group compared to that of the Hp DU-GC group,after correction for age and gender,was 1.71(95%CI:1.09-2.70;P=0.02).CONCLUSION:GU patients with H.pylori infection had higher GC incidence rates and relative risks.Atrophy of surrounding mucosa,IM and eradication therapy were associated with GC. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，16： | 15 |
| 9 | Molecular approaches for the detection and monitoring of microbial communities in bioaerosols:A review显示文摘Bioaerosols significantly affect atmospheric processes while they undergo long-range vertical and horizontal transport and influence atmospheric chemistry and physics and climate change.Accumulating evidence suggests that exposure to bioaerosols may cause adverse health effects,including severe disease.Studies of bioaerosols have primarily focused on their chemical composition and largely neglected their biological composition and the negative effects of biological composition on ecosystems and human health.Here,current molecular methods for the identification,quantification,and distribution of bioaerosol agents are reviewed.Modern developments in environmental microbiology technology would be favorable in elucidation of microbial temporal and spatial distribution in the atmosphere at high resolution.In addition,these provide additional supports for growing evidence that microbial diversity or composition in the bioaerosol is an indispensable environmental aspect linking with public health. | Keunje Yoo Tae Kwon Lee Eun Joo Choi Jihoon Yang Sudheer Kumar Shukla Sang-il Hwang Joonhong Park | 2017 | Journal of Environmental Sciences2017，29，1： | 13 |
| 10 | Management of entecavir-resistant chronic hepatitis B with adefovir-based combination therapies显示文摘AIM: To evaluate the long-term efficacy adefovir(ADV)-based combination therapies in entecavir(ETV)-resistant chronic hepatitis B(CHB) patients. METHODS: F i fty CHB pat ient s wi t h genotypic resistance to ETV at 13 medical centers in South Korea were included for the analysis. All the patients received rescue therapy with the combination of ADV plus ETV(ADV/ETV,n = 23) or ADV plus lamivudine(LMV)(ADV/LMV,n = 27) for more than 12 mo. Patients were monitored at least every 3-4 mo during ADV-based combination therapy by clinical examination as well as biochemical and virological assessments. Hepatitis B virus(HBV) DNA levels were measured by realtime PCR and logarithmically transformed for analysis. Cumulative rates of virologic response(VR; HBV DNA < 20 IU/m L) were calculated using the Kaplan-Meier method,and the difference was determined by a logrank test. Multivariate logistic regression and Cox proportional hazards models were used to identify independent risk factors significantly associated with short-term and long-term VR,respectively.RESULTS: Baseline median HBV DNA levels were 5.53(2.81-7.63) log10 IU/m L. The most commonly observed ETV genotypic mutation sites were rt184 and rt202. Patients were treated for a median of 27(12-45) mo. Overall,cumulative VR rates at 6,12,24,and 36 mo were 26%,36%,45%,and 68%,respectively. Patients treated with the ADV/ETV combination showed higher cumulative VR rates(35%,43%,65%,and 76%,respectively) than those with the ADV/LAM combination(18%,30%,30%,and 62%,respectively; P = 0.048). In the multivariate analysis,low baseline HBV DNA levels(< 5.2 log10 IU/m L) and initial virologic response at 3 mo(IVR-3; HBV DNA < 3.3 log10 IU/m L after 3 mo) were independent predictive factors for VR. Patients with favorable predictors achieved cumulative VR rates up to 90% at 36 mo. During the same period,the cumulative incidence of virologic breakthrough was as low as 6% in patients with the both favorable predictors.CONCLUSION: If tenofovir is not available,ADV/ETV combination could be considered in ETV-resistant patients with low HBV DNA titers,and may becontinued if IVR-3 is achieved. | Hyoung Su Kim Hyung Joon Yim Myoung Kuk Jang Ji Won Park Sang Jun Suh Yeon Seok Seo Ji Hoon Kim Bo Hyun Kim Sang Jong Park Sae Hwan Lee Sang Gyune Kim Young Seok Kim Jung Il Lee Jin-Woo Lee In Hee Kim Tae Yeob Kim Jin-Wook Kim Sook-Hyang Jeong Young Kul Jung Hana Park Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015，21，38： | 13 |
| 11 | CCL7 and CCL21 overexpression in gastric cancer is associated with lymph node metastasis and poor prognosis显示文摘AIM:To investigate how a complex network of CC chemokine ligands(CCLs) and their receptors influence the progression of tumor and metastasis.METHODS:In the present study,we used immunohistochemistry to examine the expression of CCL7,CCL8 and CCL21 in 194 gastric cancer samples and adjacent normal tissues.We analyzed their correlation with tumor metastasis,clinicopathologic parameters and clinical outcome.RESULTS:We found that the higher expression of CCL7 and CCL21 in cancer tissues than in normal tissues was significantly correlated with advanced depth of wall invasion,lymph node metastasis and higher tumor node metastasis stage.Moreover,Kaplan-Meier survival analysis revealed that CCL7 and CCL21 overexpression in cancer tissues was correlated with poor prognosis.CONCLUSION:These results suggest that overexpression of these two CC chemokine ligands is associated with tumor metastasis and serves as a prognostic factor in patients with gastric cancer. | Tsann-Long Hwang Li-Yu Lee Chee-ChanWang Ying Liang Shu-Fang Huang Chi-Ming Wu | 2012 | World Journal of Gastroenterology2012，18，11： | 12 |

| 13 | Health-related quality of life and impact of antiviral treatment in Chinese patients with chronic hepatitis C in Taiwan显示文摘AIM: To evaluate health-related quality of life (HRQOL) in Chinese patients with chronic hepatitis C (CH-C), and the impact of antiviral treatment.METHODS: Short Form 36 (SF-36) Health-related Quality of Life Questionnaires to interview CH-C patients, and age- and sex-matched control subjects at outpatient clinics of a medical center in Taiwan were used. Data were transformed to scores for comparisons of eight major SF-36 domains. We also enrolled consecutive CH-C patients who completed one course of antiviral treatment(interferon α with ribavirin), and measured the HRQOLbefore, at the 12th wk of treatment, at the end of treatment, and at mo 6, after stopping the treatment to evaluate the impact of antiviral treatment.RESULTS: A total of 371 outpatients were enrolled, including 182 with CH-C and 189 age- and sex-matched subjects without CH-C. CH-C subjects had obviously lower educational status (P<0.01). Mean scores of domains in general health, physical functioning, role-physical,role-emotional, vitality, and mental health of the SF-36 were significantly lower in subjects with CH-C than those without CH-C (P<0.05). In an analysis of 47 CH-C patients who received and completed the whole course of antiviral treatment, mean scores of all domains were significantly lower at wk 12 of treatment compared to baseline. The scores returned to pretreatment values by the end of treatment, but were significantly increased at mo 6 after stopping the treatment. Among the 47 CH-C patients, 21 had sustained responses and 26 had nonsustained responses to antiviral treatment. Compared to pretreatment values, subjects with sustained responses had significantly lower social functioning scores at wk 12 of treatment, and scores for all SF-36 domains returned to pretreatment values, and increased significantly at mo 6 after stopping the treatment. For non-sustained virological responders, scores of all SF-36 domains significantly decreased at wk 12 of treatment, and did not increase significantly by the end of treatment, or at mo 6 after stopping the treatment when compared to the pre treatment values.CONCLUSION: HRQOL in CH-C patients is significantly impaired in most SF-36 domains. Antiviral treatment impaired HRQOL of CH-C subjects during early treatment, mainly in non-sustained virological responders, and improved at mo 6 after stopping the treatment, mainly in sustained virological responders. | Shih-Chao Kang Shinn-Jang Hwang Shiang-Ho Lee Full-Young Chang Shou-Dong Lee | 2005 | World Journal of Gastroenterology2005，11，47： | 11 |
| 14 | Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival. | Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |

| 16 | Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes. | Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park | 2017 | Neural Regeneration Research2017，12，2： | 9 |
| 17 | Comparison of postpolypectomy bleeding between epinephrine and saline submucosal injection for large colon polyps by conventional polypectomy:A prospective randomized,multicenter study显示文摘AIM:To evaluate and compare the clinical outcomes of prophylactic submucosal saline-epinephrine injection and saline injection alone for large colon polyps by conventional polypectomy. METHODS:A prospective study was conducted from July 2003 to July 2004 at 11 tertiary endoscopic centers. Large colon polyps (> 10 mm in diameter) wererandomized to undergo endoscopic polypectomy with submucosal saline-epinephrine injection (epinephrine group) or normal saline injection (saline group). Endoscopic polypectomy was performed by the conventional snare method,and early (< 12 h) and late bleeding complications (12 h-30 d) were observed. RESULTS:A total of 561 polyps in 486 patients were resected by endoscopic polypectomy. Overall,bleeding complications occurred in 7.6% (37/486) of the patients,including 4.9% (12/244) in the epinephrine group,and 10.3% (25/242) in the saline group. Early and late postpolypectomy bleeding (PPB) occurred in 6.6% (32/486) and 1% (5/486) of the patients,respectively,including 4.5% (11/244),0.4% (1/244) in the epinephrine group,and 8.7% (21/242),1.7% (4/242) in the saline group. No significant differences in the rates of overall,early and late PPB were observed between the 2 groups. Multivariate stepwise logistic regression analysis revealed that large size (> 2 cm) and neoplastic polyps were independently and significantly associated with the presence of PPB. CONCLUSION:The prophylactic submucosal injection of diluted epinephrine does not appear to provide an additional advantage over the saline injection alone for the prevention of PPB. | Suck-Ho Lee Il-Kwun Chung Sun-Joo Kim Jin-Oh Kim Bong-Min Ko Won-Ho Kim Hyun-Soo Kim Dong-IL Park Hyo-Jong Kim Jeong-Sik Byeon Suk-Kyun Yang Byeong Ik Jang Sung-Ae Jung Yoon-Tae Jeen Jai-Hyun Choi Hwang Choi Dong-Soo Han Jae Suk Song | 2007 | World Journal of Gastroenterology2007，13，21： | 9 |
| 18 | Retrospective analysis of extra-gastrointestinal stromal tumors显示文摘AIM:To investigate the clinicopathologic features of patients with extra-gastrointestinal stromal tumors(EGISTs)in South Korea.METHODS:A total of 51 patients with an EGIST were identified.The clinicopathologic features,including sex,age,location,tumor size,histology,mitotic rate,immunohistochemical features,genetic status and survival data,were analyzed.RESULTS:The median age was 55 years(range:29-80years),and male:female ratio was 1:1.04.The most common site was in the mesentery(n=15)followed by the retroperitoneum(n=13)and omentum(n=8).The median tumor size was 9.0 cm(range:2.6-30.0cm)and the median mitotic rate was 5.0/50HPF.(1/50-185/50).KIT was analyzed in 16,which revealed 10cases with wild-type KIT and 6 cases with an exon 11mutation.Among 51 patients,31 patients had undergone surgery,and 10 had unresectable disease and had taken palliative imatinib,which resulted in 22.7 mo of progression-free survival.Of the patients who had undergone surgery,18 did not take adjuvant imatinib,and 8 of these were categorized as'high risk'according to the risk criteria.However,the relapse-free survival was not different(P=0.157)between two groups.CONCLUSION:Because the biologic behaviors of GISTs differ according to the location of the tumor,a more stratified strategy is required for managing EGISTs including incorporation of molecular features. | Jun Ho Yi Byeong-Bae Park Jung Hun Kang In Gyu Hwang Dong Bok Shin Sun Jin Sym Hee Kyung Ahn Soon Il Lee Do Hyoung Lim Keon Woo Park Young-Woong Won Sung Hee Lim Se Hoon Park | 2015 | World Journal of Gastroenterology2015，21，6： | 9 |

| 20 | Risk factors for local recurrence after en bloc endoscopic submucosal dissection for early gastric cancer显示文摘AIM: To investigate factors related to recurrence following en bloc resection using endoscopic submucosal dissection(ESD) in patients with early gastric cancer(EGC). METHODS: A total of 1121 patients(1215 lesions) who had undergone ESD for gastric neoplasia between April 2003 and May 2010 were retrospectively reviewed. Data from 401 patients(415 lesions) were analyzed, following the exclusion of those who underwent piecemeal resection, with deep resection margin invasion or lateral margin infiltration, and diagnosed with benign lesions. RESULTS: Local recurrence after en bloc ESD was found in 36 cases(8.7%). Unclear resection margins, long procedure times, and narrow safety margins were identified as risk factors for recurrence. Lesions located in the upper third of the stomach showed a higher rate of recurrence than those located in the lower third of the stomach(OR = 2.9, P = 0.03). The probability of no recurrence for up to 24 mo was 79.9% in those with a safety resection margin ≤ 1 mm and 89.5% in those with a margin > 1 mm(log-rank test, P = 0.03). CONCLUSION: Even in cases in which en bloc ESD is performed for EGC, local recurrence still occurs. To reduce local recurrences, more careful assessment will be needed prior to the implementation of ESD in casesin which the tumor is located in the upper third of the stomach. In addition, clear identification of tumor boundaries as well as the securing of sufficient safety resection margins will be important. | Ju Yup Lee Kwang Bum Cho Eun Soo Kim Kyung Sik Park Yoo Jin Lee Yoon Suk Lee Byoung Kuk Jang Woo Jin Chung Jae Seok Hwang | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，7： | 8 |
