| 1 | Endoscopic removal of gastric ectopic pancreas:An initial experience with endoscopic submucosal dissection显示文摘AIM:To evaluate the therapeutic usefulness and safety of endoscopic resection in patients with gastric ectopic pancreas.METHODS:A total of eight patients with ectopic pancreas were included.All of them underwent endoscopic ultrasonography before endoscopic resection.Endo-scopic resection was performed by two methods:endo-scopic mucosal resection(EMR)by the injection-and-cut technique or endoscopic mucosal dissection(ESD).RESULTS:We planned to perform EMR in all eight cases but EMR was successful in only four cases.In the other four cases,saline spread into surrounding normal tissues and the lesions becameattened,which made it impossible to remove them by EMR.Inthose four cases,we performed ESD and removed the lesions without any complications.CONCLUSION:If conventional EMR is difficult to remove gastric ectopic pancreas,ESD is a feasible alternative method for successful removal. | Dong Yup Ryu Gwang Ha Kim Do Youn Park Bong Eun Lee Jae Hoon Cheong Dong Uk Kim Hyun Young Woo Jeong Heo Geun Am Song | 2010 | World Journal of Gastroenterology2010，16，36： | 24 |
| 2 | Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS?显示文摘AIM: To evaluate the ultrasonog raphy (EUS) features of gastric gastrointestinal stromal tumors (GISTs) as compared with gastric leiomyomas and then to determine the EUS features that could predict malignant GISTs.METHODS: We evaluated the endoscopic EUS features in 53 patients with gastric mesenchymal tumors conf irmed by histopathologic diagnosis. The GISTs were classif ied into benign and malignant groups according to the histological risk classif ication.RESULTS: Immunohistochemical analyses demon-strated 7 leiomyomas and 46 GISTs. Inhomogenicity, hyperechogenic spots, a marginal halo and higher echogenicity as compared with the surrounding muscle layer appeared more frequently in the GISTs than in the leiomyomas (P < 0.05). The presence of at least two of these four features had a sensitivity of 89.1% and a specifi city of 85.7% for predicting GISTs. Except for tumor size and irregularity of the border, most of the EUS features were not helpful for predicting the malignant potential of GISTs. On multivariate analysis, only the maximal diameter of the GISTs was an independent predictor. The optimal size for predicting malignant GISTs was 35 mm. The sensitivity and specificity using this value were 92.3% and 78.8%, respectively.CONCLUSION: EUS may help to differentiate gastric GISTs from gastric leiomyomas. Once GISTs are suspected, surgery should be considered if the size is greater than 3.5 cm. | Gwang Ha Kim Do Youn Park Suk Kim Dae Hwan Kim Dong Heon Kim Cheol Woong Choi Jeong Heo Geun Am Song | 2009 | World Journal of Gastroenterology2009，15，27： | 12 |
| 3 | Clinicopathologic factors influencing the accuracy of EUS for superficial esophageal carcinoma显示文摘AIM:To identify clinicopathologic factors influencing the accuracy of a high-frequency catheter probe endoscopic ultrasonography(EUS)for superficial esophageal carcinomas(SECs).METHODS:A total of 126 patients with endoscopically suspected SEC,who underwent EUS and curative treatment at Pusan National University Hospital during2005-2013,were enrolled.We reviewed the medical records of the 126 patients and compared EUS findings with histopathologic results according to clinicopathologic factors.RESULTS:A total of 114 lesions in 113 patients were included in the final analysis.The EUS assessment of tumor invasion depth was accurate in 78.9%(90/114)patients.Accuracy did not differ according to histologic type,tumor differentiation,tumor location,or macroscopic shape.However,accuracy significantly decreased for tumors≥3 cm in size(P=0.002).Overestimation and underestimation of the invasion depth occurred for 11(9.6%)and 13 lesions(11.4%),respectively.In multivariate analyses,tumor size≥3 cm was the only factor significantly associated with EUS accuracy(P=0.031),and was specifically associated with the underestimation of invasion depth.CONCLUSION:EUS using a high-frequency catheter probe generally provides highly accurate assessments of SEC invasion depth,but its accuracy decreases for tumors≥3 cm. | Jung Im Jung Gwang Ha Kim Hoseok I Do Youn Park Tae Kyun Kim Young Hwa Cho Yong Wan Sung Mun Ki Choi Bong Eun Lee Geun Am Song | 2014 | World Journal of Gastroenterology2014，20，20： | 9 |
| 4 | Associated factors for a hyperechogenic pancreas on endoscopic ultrasound显示文摘AIM: To identify the associated risk factors for hyperechogenic pancreas (HP) which may be observed on endoscopic ultrasound (EUS) and to assess the relationship between HP and obesity. METHODS: From January 2007 to December 2007, we prospectively enrolled 524 consecutive adults who were scheduled to undergo EUS. Patients with a history of pancreatic disease or with hepatobiliary or advanced gastrointestinal cancer were excluded. Finally,284 patients were included in the analyses. We further analyzed the risk of HP according to the categories of visceral adipose tissue (VAT) and subcutaneous adipose tissue in 132 patients who underwent abdominal computed tomography scans. RESULTS: On univariate analysis, age older than 60 years, obesity (body mass index > 25 kg/m 2 ), fatty liver, diabetes mellitus, hypertension and hypercholesterolemia were identified as risk factors associated with HP (P < 0.05). On multivariate analysis, fatty liver [P = 0.008, odds ratio (OR) = 2.219], male gender (P = 0.013, OR = 2.636), age older than 60 years (P = 0.001, OR = 2.874) and hypertension (P = 0.044, OR = 2.037) were significantly associated with HP. In the subgroup analysis, VAT was a statistically significant risk factor for HP (P = 0.010, OR = 5.665, lowest quartile vs highest quartile). CONCLUSION: HP observed on EUS was associated with fatty liver, male gender, age older than 60 years, hypertension and VAT. | Cheol Woong Choi Gwang Ha Kim Dae Hwan Kang Hyung Wook Kim Dong Uk Kim Jeong Heo Geun Am Song Do Youn Park Suk Kim | 2010 | World Journal of Gastroenterology2010，16，34： | 8 |

| 6 | Magnifying endoscopy of gastric epithelial dysplasia based on the morphologic characteristics显示文摘AIM:To investigate the difference in magnifying endoscopic findings of gastric epithelial dysplasias(GEDs)according to the morphologic characteristics.METHODS:This study included 46 GED lesions in 45patients who underwent magnifying endoscopy using narrow band imaging(ME-NBI)before endoscopic resection.During ME-NBI,the microvascular and microsurface(MS)patterns and the presence of light blue crest(LBC)and white opaque substance were investigated.GEDs were categorized as adenomatous,foveolar,and hybrid types,and their mucin phenotype was evaluated.RESULTS:Of the 46 lesions,27(59%)were categorized as adenomatous,15(32%)as hybrid,and the remaining 4(9%)as foveolar.All adenomatous GEDs showed the round pit and/or tubular MS patterns,all foveolar GEDs showed the papillary pattern,and hybrid GEDs showed mixed patterns(P<0.001).LBC was more frequently observed in adenomatous GEDs than in hybrid or foveolar GEDs(52%,33%,0%,respectively),although this difference was not significant(P=0.127).The papillary MS pattern was associated with MUC5AC and MUC6 expression,and the round pit and/or tubular MS patterns were associated with CD10expression.CONCLUSION:The MS pattern in ME-NBI findings is useful for predicting the morphologic category and mucin phenotype of GEDs,and ME-NBI findings may guide decisions regarding GED treatment. | Hwa Mi Kang Gwang Ha Kim Do Youn Park Hong Ryeol Cheong Dong Hoon Baek Bong Eun Lee Geun Am Song | 2014 | World Journal of Gastroenterology2014，20，42： | 4 |
| 7 | Is ineffective esophageal motility associated with gastropharyngeal reflux disease?显示文摘AIM: To evaluate the association between ineffective esophageal motility (IEM) and gastropharyngeal reflux disease (GPRD) in patients who underwent ambulatory 24-h dual-probe pH monitoring for the evaluation of supraesophageal symptoms. METHODS: A total of 632 patients who underwent endoscopy,esophageal manometry and ambulatory 24-h dual-pH monitoring due to supraesophageal symptoms (e.g. globus,hoarseness,or cough) were enrolled. Of them,we selected the patients who had normal esophageal motility and IEM. The endoscopy and ambulatory pH monitoring findings were compared between the two groups. RESULTS: A total of 264 patients with normal esophageal motility and 195 patients with the diagnosis of IEM were included in this study. There was no difference in the frequency of reflux esophagitis and hiatal hernia between the two groups. All the variables showing gastroesophageal reflux and gastropharyngeal reflux were not different between the two groups. The frequency of GERD and GPRD,as defined by ambulatory pH monitoring,was not different between the two groups. CONCLUSION: There was no association between IEM and GPRD as well as between IEM and GERD. IEM alone cannot be considered as a definitive marker for reflux disease. | Kyung Yup Kim Gwang Ha Kim Dong Uk Kim Soo Geun Wang Byung Joo Lee Jin Choon Lee Do Youn Park Geun Am Song | 2008 | World Journal of Gastroenterology2008，14，39： | 3 |

| 13 | Endoscopic resection of sparganosis presenting as colon submucosal tumor: A case report显示文摘Human sparganosis is a rare parasitic disease caused by infection with the tapeworm Sparganum, the migrating plerocercoid(second stage) larva of Spirometra species. Sparganosis usually involves subcutaneous tissues and/or muscles of various parts of the body, but involvement of other sites such as the brain, eye, peritoneopleural cavity, urinary track, scrotum, and abdominal viscera has also been documented. Infections caused by sparganum have a worldwide distribution but are most common in Southeast Asia such as China, Japan, and South Korea. Rectal sparganosis is an uncommon disease but should be considered in the differential diagnosis of unusual and suspicious rectal submucosal tumors. We report a case of rectal sparganosis presenting as rectal submucosal tumor. We performed endoscopic submucosal dissection of the rectal submucosal tumor. The sparganosis was confirmed based on the presence of calcospherules in the submucosal layer on histological examination. Moreover, the result of the immunoglobulin G antibody test for sparganosis was positive but became negative after endoscopic submucosal dissection. Though rare, rectal sparganosis should be considered in the differential diagnosis of rectal submucosal tumor-like lesions. This case suggests that physicians should make effort to exclude sparganosis through careful diagnostic approaches, including detailed history taking and serological tests for parasites. In this report, we aimed to highlight the clinical presentation of Sparganum infection as a rectal submucosal tumor. | Joong Keun Kim Dong Hoon Baek Bong Eun Lee Gwang Ha Kim Geun Am Song Do Youn Park | 2016 | World Journal of Gastroenterology2016，22，19： | 1 |

| 15 | Is endoscopic submucosal dissection safe for papillary adenocarcinoma of the stomach?显示文摘AIM: To identify the clinicopathological predictors of lymph node(LN) metastasis and evaluate the outcomes of endoscopic submucosal dissection(ESD) in papillary adenocarcinoma-type early gastric cancers(EGCs).METHODS: From January 2005 to May 2013, 49 patients who underwent surgical operation and 24 patients who underwent ESD for papillary adenocarcinomatype EGC were enrolled to identify clinicopathological characteristics and predictive factors of LN metastasis and to evaluate the outcomes of ESD for papillary adenocarcinoma-type EGC.RESULTS: Most papillary adenocarcinoma-type EGCs were located in the lower third of the stomach and had an elevated macroscopic shape. The overall prevalence of LN metastasis was 18.3%(9/49). The presence of lymphovascular invasion was found to be a predictor of LN metastasis(P = 0.016). According to current indication criteria of ESD, 6 and 11 of the 49 patients had absolute and expanded indications for ESD, respectively. Two patients(11.8%) with expanded indication for ESD had LN metastasis. Of the 24 patients who underwent ESD, 13(54%) achieved out-of-ESD indication, with 9 of those 13 patients undergoing surgical operation due to non-curative resection. CONCLUSION: The use of ESD should be carefully considered for papillary adenocarcinoma-type EGC with suspected ESD indication after pre-treatment work-up because of the higher frequency of LN metastasis and additional surgeries. | Hyun Jeong Lee Gwang Ha Kim Do Youn Park Bong Eun Lee Hye Kyung Jeon Joon Hyung Jhi Geun Am Song | 2015 | World Journal of Gastroenterology2015，21，13： | 0 |
