| 1 | 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 |
| 2 | Long-term follow up of endoscopic resection for type 3 gastric NET显示文摘AIM:To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3gastric neuroendocrine tumors(NETs).METHODS:Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011,50 patients treated with endoscopic resection were enrolled in this study.For endoscopic resection,endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESD)was used.Therapeutic efficacy,complications,and follow-up results were evaluated retrospectively.RESULTS:EMR was performed in 41 cases and ESD in 9 cases.Pathologically complete resection was performed in 40 cases(80.0%)and incomplete resection specimens were observed in 10 cases(7 vs 3 patients in the EMR vs ESD group,P=0.249).Upon analysis of the incomplete resection group,lateral or vertical margin invasion was found in six cases(14.6%)in the EMR group and in one case in the ESD group(11.1%).Lymphovascular invasions were observed in two cases(22.2%)in the ESD group and in one case(2.4%)in the EMR group(P=0.080).During the follow-up period(43.73;13-60 mo),there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group.No recurrence was reported during follow-up.In addition,no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.CONCLUSION:Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion,endoscopic treatment could be considered at initial treatment. | Yong Hwan Kwon Seong Woo Jeon Gwang Ha Kim Jin Il Kim Il-Kwun Chung Sam Ryong Jee Heung Up Kim Geom Seog Seo Gwang Ho Baik Kee Don Choi Jeong Seop Moon | 2013 | World Journal of Gastroenterology2013，19，46： | 14 |
| 3 | Intravoxel incoherent motion diffusion-weighted imaging for monitoring chemotherapeutic efficacy in gastric cancer显示文摘AIM: To assess intravoxel incoherent motion diffusionweighted imaging(IVIM-DWI) for monitoring early efficacy of chemotherapy in a human gastric cancer mouse model.METHODS: IVIM-DWI was performed with 12 b-values(0-800 s/mm2) in 25 human gastric cancer-bearing nude mice at baseline(day 0), and then they were randomly divided into control and 1-, 3-, 5- and 7-d treatment groups(n = 5 per group). The control group underwent longitudinal MRI scans at days 1, 3, 5 and 7, and the treatment groups underwent subsequent MRI scans after a specified 5-fluorouracil/calciumfolinate treatment. Together with tumor volumes(TV), the apparent diffusion coefficient(ADC) and IVIM parameters [true water molecular diffusion coefficient(D), perfusion fraction(f) and pseudo-related diffusion coefficient(D*)] were measured. The differences in those parameters from baseline to each measurement(ΔTV%, ΔADC%, ΔD%, Δf% and ΔD*%) were calculated. After image acquisition, tumor necrosis, microvessel density(MVD) and cellular apoptosis were evaluated by hematoxylin-eosin(HE), CD31 and terminal-deoxynucleotidyl transferase mediated nick end labeling(TUNEL) staining respectively, to confirm the imaging findings. Mann-Whitney test and Spearman's correlation coefficient analysis were performed.RESULTS: The observed relative volume increase(ΔTV%) in the treatment group were significantly smaller than those in the control group at day 5(ΔTV_(treatment)% = 19.63% ± 3.01% and ΔTVcontrol% = 83.60% ± 14.87%, P = 0.008) and day 7(ΔTV_(treatment)% = 29.07% ± 10.01% and ΔTV_(control)% = 177.06% ± 63.00%, P = 0.008). The difference in ΔTV% between the treatment and the control groups was not significant at days 1 and 3 after a short duration of treatment. Increases in ADC in the treatment group(ΔADC%_(treatment), median, 30.10% ± 18.32%, 36.11% ± 21.82%, 45.22% ± 24.36%) were significantly higher compared with the control group(ΔADC%_(control), median, 4.98% ± 3.39%, 6.26% ± 3.08%, 9.24% ± 6.33%) at days 3, 5 and 7(P = 0.008, P = 0.016, P = 0.008, respectively). Increases in D in the treatment group(ΔD%_(treatment), median 17.12% ± 8.20%, 24.16% ± 16.87%, 38.54% ± 19.36%) were higher than those in the control group(ΔD%_(control), median-0.13% ± 4.23%, 5.89% ± 4.56%, 5.54% ± 4.44%) at days 1, 3, and 5(P = 0.032, P = 0.008, P = 0.016, respectively). Relative changes in f were significantly lower in the treatment group compared with the control group at days 1, 3, 5 and 7 follow-up(median,-34.13% ± 16.61% vs 1.68% ± 3.40%, P = 0.016;-50.64% ± 6.82% vs 3.01% ± 6.50%, P = 0.008;-49.93% ± 6.05% vs 0.97% ± 4.38%, P = 0.008, and-46.22% ± 7.75% vs 8.14% ± 6.75%, P = 0.008, respectively). D* in the treatment group decreased significantly compared to those in the control group at all time points(median,-32.10% ± 12.22% vs 1.85% ± 5.54%, P = 0.008;-44.14% ± 14.83% vs 2.29% ± 10.38%, P = 0.008;-59.06% ± 19.10% vs 3.86% ± 5.10%, P = 0.008 and-47.20% ± 20.48% vs 7.13% ± 9.88%, P = 0.016, respectively). Furthermore, histopathologic findings showed positive correlations with ADC and D and tumor necrosis(r_s = 0.720, P < 0.001; r_s = 0.522, P = 0.007, respectively). The cellular apoptosis of the tumor also showed positive correlations with ADC and D(r_s = 0.626, P = 0.001; r_s = 0.542, P = 0.005, respectively). Perfusionrelated parameters(f and D*) were positively correlated to MVD(r_s = 0.618, P = 0.001; r_s = 0.538, P = 0.006, respectively), and negatively correlated to cellular apoptosis of the tumor(r_s =-0.550, P = 0.004; r_s =-0.692, P < 0.001, respectively).CONCLUSION: IVIM-DWI is potentially useful for predicting the early efficacy of chemotherapy in a human gastric cancer mouse model. | Xiao-Li Song Heoung Keun Kang Gwang Woo Jeong Kyu Youn Ahn Yong Yeon Jeong Yang Joon Kang Hye Jung Cho Chung Man Moon | 2016 | World Journal of Gastroenterology2016，22，24： | 12 |
| 4 | Low grade gastric mucosa associated lymphoid tissue lymphoma:Treatment strategies based on 10 year follow-up显示文摘AIM:To deduce strategic guidelines of gastric mucosa associated lymphoid tissue lymphoma (MALTOMA) by evaluating the long-term outcome of patients in respect to various treatment modalities.METHODS:A total of 55 patients with MALTOMA from May 1992 to August 2002 were retrospectively reviewed.RESULTS: Complete remission was obtained in 24 (82.8%) of 29 patients treated with anti Helicobacter pylori(H pylori) regimen only. The duration to reach complete remission was 12 months (85 percentile, 2-33 months).Five patients showed complete remission with radiation therapy (26-86 months).Two of them were Hpyloritreatment failure cases.CONCLUSION: Hpylorieradication is an effective primary treatment option for low grade MALTOMA and radiation therapy could be considered in patients with no evidence of Hpyloninfection or who do not respond to Hpylorieradication therapy 12 months after successful eradication. | Sang Kil Lee Yong Chan Lee Jae Bock Chung Chae Yoon Chon Young Myoung Moon Jin Kyung Kang In-Suh Park Chang Ok Suh Woo Ik Yang | 2004 | World Journal of Gastroenterology2004，10，2： | 12 |
| 5 | Preoperative colonoscopy through the colonic stent in patients with colorectal cancer obstruction显示文摘AIM:To evaluate the feasibility of a preoperative colonoscopy through a self-expendable metallic stent(SEMS)and to identify the factors that affect complete colonoscopy.METHODS:A total of 48 patients who had SEMS placement because of acute malignant colonic obstruction underwent preoperative colonoscopy.After effective SEMS placement,patients who showed complete resolution of radiological findings and clinical signs of acute colon obstruction underwent a standard bowel preparation.Preoperative colonoscopy was then performed using a standard colonoscope.If the passage of colonoscope was not feasible gastroscope was used.After colonoscopy,cecal intubation time,grade of bowel preparation,tumor location,stent location,presence of synchronous polyps or cancer,damage to colonoscopy and bleeding,and stent migration after colonoscopy were recorded.RESULTS:Complete evaluation with colonoscope was possible in 30 patients(62.5%).In this group,adenoma was detected in 13 patients(43.3%).The factors that affected complete colonoscopy were also analyzed:Tumor location at an angle;stent placement at an angle;and stent expansion diameter,which affected complete colonoscopy significantly.However in multivariate analysis,stent expansion diameter was the only significant factor that affected complete colonoscopy.Complete evaluation using additional gastroscope was feasible in 42 patients(87.5%).CONCLUSION:Preoperative colonoscopy through the colonic stent using only conventional colonoscope was unfavorable.The narrow expansion diameter of the stent may predict unfavorable outcome.In such a case,using small caliber scope should be considered and may expect successful outcome. | Jin Su Kim Kang Moon Lee Sang Woo Kim Eun Jung Kim Chul Hyun Lim Seong Taek Oh Myung Gyu Choi Kyu Yong Choi | 2014 | World Journal of Gastroenterology2014，20，30： | 11 |
| 6 | Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. | Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park | 2008 | World Journal of Gastroenterology2008，14，6： | 10 |
| 7 | Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan. | Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung | 2013 | World Journal of Gastroenterology2013，19，40： | 6 |
| 8 | Acute mediastinitis arising from pancreatic mediastinal fistula in recurrent pancreatitis显示文摘Acute mediastinitis is a fatal disease that usually originates from esophageal perforation and surgical infection.Rare cases of descending necrotizing mediastinitis can occur following oral cavity and pharynx infection or can be a complication of pancreatitis.The most common thoracic complications of pancreatic disease are reactive pleural effusion and pneumonia,while rare complications include thoracic conditions,such as pancreaticopleural fistula with massive pleural effusion or hemothorax and extension of pseudocyst into the mediastinum.There have been no reports of acute mediastinitis originating from pancreatitis in South Korea.In this report,we present the case of a 50-year-old female suffering from acute mediastinitis with pleural effusion arising from recurrent pancreatitis that improved after surgical intervention. | In Soo Choe Yong Seok Kim Tae Hee Lee Sun Moon Kim Kyung Ho Song Hoon Sup Koo Jung Ho Park Jin Sil Pyo Ji Yeong Kim In Seok Choi | 2014 | World Journal of Gastroenterology2014，20，40： | 6 |
| 9 | Effects of vagus nerve preservation and vagotomy on peptide YY and body weight after subtotal gastrectomy显示文摘AIM:To investigate the relationship between the function of vagus nerve and peptide YY 3-36 and ghrelin levels after subtotal gastrectomy.METHODS:We enrolled a total of 16 patients who underwent subtotal gastrectomy due to gastric cancer.All surgeries were performed by a single skilled surgeon.We measured peptide YY 3-36,ghrelin,leptin,insulin,growth hormone levels,and body weight immediately before and one month after surgery.RESULTS:Vagus nerve preservation group showed less body weight loss and less increase of peptide YY 3-36 compared with vagotomy group(-5.56 ± 2.24 kg vs-7.85 ± 1.57 kg,P = 0.037 and 0.06 ± 0.08 ng/mL vs 0.19 ± 0.12 ng/mL,P = 0.021,respectively).Moreover,patients with body weight loss of less than 10% exhibited reduced elevation of peptide YY 3-36 level,typically less than 20% [6(66.7%) vs 0(0.0%),P = 0.011,odd ratio = 3.333,95% confidence interval(1.293,8.591)].CONCLUSION:Vagus nerve preservation contributes to the maintenance of body weight after gastrectomy,and this phenomenon may be related to the suppressed activity of peptide YY 3-36. | Hyung Hun Kim Moo In Park Sang Ho Lee Hyun Yong Hwang Sung Eun Kim Seun Ja Park Won Moon | 2012 | World Journal of Gastroenterology2012，18，30： | 6 |
| 10 | Signet-ring cell carcinoma arising from a fundic gland polyp in the stomach显示文摘Fundic gland polyps(FGPs)are currently the most common type of gastric polyps and are usually benign.However,although rare,gastric adenocarcinoma of FGP has been recently proposed as a new variant of gastric adenocarcinoma.Here we report the first case of a49-year-old woman with focal signet ring cell carcinoma that arose from an FGP of the stomach.The tumor was completely excised by endoscopic snare polypectomy.FGPs should therefore be evaluated for malignant changes although they occur rarely,if the FGP has an erosive or irregular surface. | Yong Seol Jeong Sung Eun Kim Mi-Jung Kwon Jae Yong Seo Hyun Lim Ji Won Park Ho Suk Kang Sung Hoon Moon Jong Hyuk Kim Choong Kee Park | 2014 | World Journal of Gastroenterology2014，20，47： | 6 |

| 13 | Endoscopic treatment of efferent loop syndrome with insertion of double pigtail stent显示文摘Efferent loop syndrome is a very rare postgastrectomy syndrome that can occur following Billroth-Ⅱor Rouxen-Y reconstruction.The most common loop syndrome after gastric surgery is afferent loop syndrome;however,efferent loop syndrome has been reported in rare cases.Here,we report a case of efferent loop obstruction that occurred after postoperative adhesiolysis of a small-bowel obstruction.The patient had undergone a partial gastrectomy with BillrothⅡanastomosis and gastric ulcer perforation 30 years prior.The efferent loop obstruction was successfully resolved by the insertion of a double pigtail stent.To the best of our knowledge,this is the first case in the literature describing the treatment of efferent loop obstruction. | Woo Yong Lee Jeong Seop Moon | 2013 | World Journal of Gastroenterology2013，19，41： | 4 |
| 14 | Evaluation of lubrication performance of crank pin bearing in a marine diesel engine显示文摘In this study, the lubrication performance of the crank pin bearing in a marine two–stroke diesel engine is evaluated to investigate the adhesional failure on the crank pin bearing. A numerical algorithm for the lubrication analysis considering motion analysis of the crank pin system is developed. The film pressure and thickness for three clearances and three lubricant temperatures are calculated. The results show that the lubricant temperature has a higher effect on film thickness than clearance. In terms of the film parameter, the operating condition that can result in solid–solid contact is investigated. We also suggest the desirable operating conditions of clearance and lubricant temperature to prevent the solid–solid contact. | Suk Man MOON Yong Joo CHO Tae Wan KIM | 2018 | Friction2018，6，4： | 3 |
| 15 | Gallbladder lymphangioma:A case report and review of the literature显示文摘Lymphangiomas are rare, benign tumors of the lymphatic system, usually present in children aged 5 years and younger. Because they are asymptomatic until the mass enlarges to cause symptoms, most lymphangiomas are diagnosed at adulthood incidentally. We experienced a case of a 60-year-old man diagnosed with a cystic lymphangioma of the gallbladder, which was successfully resected without any complication. Magnetic resonance imaging and magnetic resonance cholangiopancreatography were very helpful for the diagnosis of the cystic lesion around the gallbladder as were ultrasonography and computed tomography scan. These showed a multi-lobulated cystic mass with intact cystic duct and bile duct in the gallbladder fossa. The patient underwent an open cholecystectomy and the histological findings were consistent with a cystic lymphangioma of the gallbladder. We here report the case of cystic lymphangioma of the gallbladder with a review of the literature. | Jwa-Kyung Kim Kyo-Sang Yoo Joon Ho Moon Kwang Hyuk Park Yong Woo Chung Kyoung Oh Kim Cheol Hee Park Taeho Hahn Sang Hoon Park Jong Hyeok Kim Jang Yeong Jeon Min Jung Kim Kwang Seon Min Department of Pathology Hallym University College of Medicine Anyang Korea Choong Kee Park | 2007 | World Journal of Gastroenterology2007，13，2： | 3 |
| 16 | Acute distal common bile duct angle is risk factor for postendoscopic retrograde cholangiopancreatography pancreatitis in beginner endoscopist显示文摘BACKGROUND Post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP)is a critical and poorly managed complication of ERCP.Endoscopists need to understand the risk factors for PEP.However,the majority of studies investigating ERCP-related risk factors have included well-trained endoscopists,with the issue of endoscopist experience on PEP incidence not having been systematically evaluated.AIM To explore the risk factors for PEP in beginner endoscopists without supervision.METHODS We performed a retrospective analysis of 293 patients,with naïve papilla and no history of pancreatitis,treated using bile duct cannulation.Patients were classified according to the endoscopist’s experience(beginner vs expert).The angle of the distal common bile duct(CBD)was measured as the angle between the lower wall of the bile duct and a vertical line extending to the lower wall of the bile duct on coronal view computed tomography.RESULTS After propensity matching,there were no differences between patients treated by the expert and beginner endoscopist with regard to age,sex,mean bile duct dilatation,and ratio of benign disease.The distal CBD angle was classified as acute(>30º)or obtuse(≤30º),based on the mean angle of 29.9ºfor the group.An acute distal CBD angle was a significant risk factor for PEP for beginner(P=0.049),but not expert.CONCLUSION For beginner endoscopists first performing unsupervised ERCP,cases with an obtuse distal CBD angle may be more appropriate to lower the risk of PEP. | Sung Yong Han Dong Uk Kim Moon Won Lee Young Joo Park Dong Hoon Baek Gwang Ha Kim Geun Am Song | 2020 | World Journal of Clinical Cases2020，8，1： | 3 |
| 17 | Pancreatic hardness: Correlation of surgeon's palpation, durometer measurement and preoperative magnetic resonance imaging features显示文摘AIM To evaluate the correlation between subjective assessments of pancreatic hardness based on the palpation, objective measurements using a durometer, and magnetic resonance imaging(MRI) findings for assessing pancreatic hardness.METHODS Eighty-three patients undergoing pancreatectomies were enrolled. An experienced surgeon subjectively evaluated the pancreatic hardness in the surgical field by palpation. The pancreatic hardness was also objectivelyevaluated using a durometer. Preoperative MRI findings were evaluated by a radiologist in terms of the apparent diffusion coefficient(ADC) values, the relative signal intensity decrease(RSID) of the pancreatic parenchyma, and the diameter of the pancreatic parenchyma and duct. Durometer measurement results, ADC values, RSID, pancreatic duct and parenchyma diameters, and the ratio of the diameters of the duct and parenchyma were compared between pancreases judged to be soft or hard pancreas on the palpation. A correlation analysis was also performed between the durometer and MRI measurements.RESULTS The palpation assessment classified 44 patients as having a soft pancreas and 39 patients as having a hard pancreas. ADC values were significantly lower in the hard pancreas group. The ductal diameter and duct-to-pancreas ratio were significantly higher in the hard pancreas group. For durometer measurements, a correlation analysis showed a positive correlation with the ductal diameter and the duct-to-pancreas ratio and a negative correlation with ADC values. CONCLUSION Hard pancreases showed lower ADC values, a wider pancreatic duct diameter and a higher duct-to-pancreas ratio than soft pancreases. Additionally, the ADC values, diameter of the pancreatic duct and duct-to-pancreas ratio were closely correlated with the durometer results. | Tae Ho Hong Joon-Il Choi Michael Yong Park Sung Eun Rha Young Joon Lee Young Kyoung You Moon Hyung Choi | 2017 | World Journal of Gastroenterology2017，23，11： | 3 |
| 18 | Risk factors for metachronous gastric carcinoma development after endoscopic resection of gastric dysplasia: Retrospective, single-center study显示文摘AIM To determine the gastric adenocarcinoma(GAC)occurrence rate and related factors,we evaluated the follow-up results of patients confirmed to have gastric dysplasia after endoscopic resection(ER).METHODS We retrospectively analyzed the medical records,endoscopic examination records,endoscopic procedure records,and histological records of 667 cases from641 patients who were followed-up for at least 12mo,from among 1273 patients who were conformed to have gastric dysplasia after Endoscopic mucosal resection(EMR)or endoscopic submucosal dissection (ESD)of gastric mucosal lesions between January 2007and August 2013 at the Chungnam National University Hospital.RESULTS The mean follow-up period was 33.8 mo,and the median follow-up period was 29 mo(range:12-87).During the follow-up period,the occurrence of metachronous GAC was 4.0%(27/667).The mean and median interval periods between the occurrence of metachronous GAC and endoscopic treatment of gastric dysplasia were 36.3 and 34 mo,respectively(range:16-71).The factors related to metachronous GAC occurrence after ER for gastric dysplasia were male sex(5.3%vs 1.0%),open-type atrophic gastritis(9.5%vs3.4%),intestinal metaplasia(6.8%vs 2.4%),and highgrade dysplasia(HGD;8.4%vs 3.2%).Among them,male sex[OR:5.05(1.18-21.68),P=0.029],intestinal metaplasia[OR:2.78(1.24-6.23),P=0.013],and HGD[OR:2.70(1.16-6.26),P=0.021]were independent related factors in multivariate analysis.Furthermore,24of 27 GAC cases(88.9%)occurred at sites other than the previous resection sites,and 3(11.1%)occurred at the same site as the previous resection site.CONCLUSION Male sex,intestinal metaplasia,and HGD were significantly related to the occurrence of metachronous GAC after ER of gastric dysplasia,and most GACs occurred at sites other than the previous resection sites. | Hee Seok Moon Gee Young Yun Ju Seok Kim Hyuk Soo Eun Sun Hyung Kang Jae Kyu Sung Hyun Yong Jeong Kyu-Sang Song | 2017 | World Journal of Gastroenterology2017，23，24： | 3 |
