| 1 | Clinicopathologic factors and molecular markers related to lymph node metastasis in early gastric cancer显示文摘AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer.METHODS: We analyzed 1104 patients with early gastric cancer(EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mut L homolog 1, p53, epidermal growth factor receptor(EGFR) and human epidermal growth factor receptor 2(HER2) were included. The χ2 test and logistic regression analysis were used to determine clinicopathologic parameters.RESULTS: Lymph node metastasis was observed in 104(9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients(3.8%) were mucosal cancers and 80 patients(16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4(1.7%) for well differentiated tubular adenocarcinoma, 45(11.3%) for moderately differentiated tubular adenocarcinoma, 36(14.8%) for poorly differentiated tubular adenocarcinoma, and 19(8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases(11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases(27.1%) of 406 EGC patients. With multivariate analysis, female gender(OR = 2.281, P = 0.009), presence of lymphovascular invasion(OR = 10.950, P < 0.0001), diameter(≥ 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression(OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement.CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC. | Eun Hyo Jin Dong Ho Lee Sung-Ae Jung Ki-Nam Shim Ji Yeon Seo Nayoung Kim Cheol Min Shin Hyuk Yoon Hyun Chae Jung | 2015 | World Journal of Gastroenterology2015,21,2: | 30 |

| 3 | 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 |

| 5 | Priapism secondary to penile metastasis of rectal cancer显示文摘Metastatic penile carcinoma is rare and usually originates from genitourinary tumors. The presenting symptoms or signs have been described as nonspecific except for priapism. Rectal adenocarcinoma is a very unusual source of metastatic penile carcinoma. We report a case of metastatic penile carcinoma that originated from the rectum. Symptomatic improvement occurred with palliative radiotherapy. | Ji Chan Park Wook Hyun Lee Min Kyu Kang Suk Young Park | 2009 | World Journal of Gastroenterology2009,15,33: | 10 |
| 6 | 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 |
| 7 | Colonoscopy-induced ischemic colitis in patients without risk factors显示文摘Ischemic colitis is the most common form of intestinal ischemia.It is a condition that is commonly seen in the elderly and among individuals with risk factors for ischemia.Common predisposing conditions for ischemic colitis are major vascular occlusion,small vessel disorder,shock,some medications,colonic obstructions and hematologic disorders.Ischemic colitis following colonoscopy is rare.Here,we report two cases of ischemic colitis after a routine screening colonoscopy in patients without risk factors for ischemia. | Sang Ok Lee Sae Hee Kim Sung Hee Jung Chan Woong Park Min Ji Lee Jin A Lee Hyun Cheol Koo Anna Kim Hyun-Young Han Dong-Wook Kang | 2014 | World Journal of Gastroenterology2014,20,13: | 9 |
| 8 | Biopathologic features and clinical significance of micrometatasis in the lymph node of early gastric cancer显示文摘AIM: To evaluate the biopathologic features and clinical significance of nodal micrometastasis(MI) in early gastric cancer(EGC).METHODS: Among 1022 EGC patients who underwent gastrectomy with lymphadenectomy of D1 + β or more from March 2001 to December 2005 at the Korean National Cancer Center, available nodal metastasis was found in 90 p T1N1 patients. Nodal metastasis was confirmed by immunohistochemistry(IHC) with cytokeratin and patients were classified into MI and macrometastasis(MA) groups based on the main tumor burden according to the 6th International Union Against Cancer/American Joint Committee on Cancer staging system; the main tumor burden with a diameter of greater than 0.2 mm but no greater than 2 mm as MI, and greater than 2 mm as MA of the representative metastatic node. Proliferative and apoptotic activities of the primary tumor and the nodal metastasis were measured by IHC with Ki-67 and terminal deoxynucleotidyl transferase d UTP nick end labeling, respectively. Biopathologic and clinical features of the patients were analyzed and compared between MI and MA groups. Patients with recurrence were compared with those without recurrence to identify risk factors for recurrence.RESULTS: Thirty-seven patients showed MI and the other 53 patients revealed MA in the lymph node; the incidence of patients with MI and MA was 41.1% and 58.9%. The main tumor burden was 0.9 and 4.6 mm in the representative metastatic node, respectively. Japanese N2 stations were more frequently involved in MA group(20.9%) than in MI group(10.3%) butthe difference was not statistically different(P = 0.338). Proliferative and apoptotic activities of MI were decreased than those of MA(26.7% vs 40.5%, P = 0.004 and 1.0% vs 3.0%, P < 0.001, respectively). However, nodal MI in the current study showed a relatively high proliferative activity and an equivalent apoptotic activity compared to other cancers in the previously published studies. Recurrence was observed in 6 patients during the mean follow up period of 87.6 ± 26.2 mo. The recurrence was significantly associated with the presence of MA(P = 0.041) and lymphovascular invasion of the primary tumor(P = 0.032).CONCLUSION: Lymphadenectomy of D1 + β or more might be necessary in patients with MI in sentinel node to prevent recurrence by clearing MI involving Japanese N2 station. | Min Jung Jo Ji Yeon Park Joon Seon Song Myeong-Cherl Kook Keun Won Ryu Soo-Jeong Cho Jun Ho Lee Byung-Ho Nam Eun Kyung Hong Il Ju Choi Young-Woo Kim | 2015 | World Journal of Gastroenterology2015,21,2: | 9 |
| 9 | Clinicopathologic significance of expression of nuclear factor-kB RelA and its target gene products in gastric cancer patients显示文摘AIM:To assess the prognostic significance of nuclear factor-kB (NF-kB) and its target genes in gastric cancer. METHODS:The tumor tissues of 115 patients with gastric cancer were immunohistochemically evaluated using monoclonal antibodies against NF-kB RelA. Preoperative serum levels of vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) were assessed via enzyme-linked immuno-sorbent assay. C-reactive protein (CRP) and serum amyloid A (SAA) were measured via immunotrubidimetry. RESULTS:Positive rate of NF-kB RelA was 42.6%. NF-kB RelA expression in tumor tissues was also related to serum levels of IL-6 (P = 0.044) and CRP (P = 0.010). IL-6, SAA, CRP were related to depth of invasion, VEGF and SAA were correlated with lymph node metastasis. IL-6, VEGF, SAA and CRP were related to the stage. Univariate analysis demonstrated that immunostaining of NF-kB RelA, levels of IL-6, VEGF, SAA were significantly related with both disease free survival and over-all survival (OS). Multivariate analysis verified that NF-kB RelA [hazard ratio (HR): 3.40, P = 0.024] and SAA (HR: 3.39, P = 0.045) were independently associated with OS. CONCLUSION: Increased expression of NF-kB RelA and high levels of serum SAA were associated with poor OS in gastric cancer patients. | Hyuk-Chan Kwon Sung-Hyun Kim Sung Yong Oh Suee Lee Ji Hyun Lee Jin Seok Jang Min Chan Kim Ki Han Kim Su-Jin Kim Seong-Geun Kim Hyo-Jin Kim | 2012 | World Journal of Gastroenterology2012,18,34: | 9 |
| 10 | Epstein-Barr virus-associated lymphoepithelioma-like early gastric carcinomas and endoscopic submucosal dissection: Case series显示文摘Epstein-Barr virus(EBV)-associated lymphoepitheliomalike gastric carcinoma(LELC) is characterized by a lower lymph node(LN) metastasis rate and a higher survival rate than other forms of gastric cancer. Although current prognosis for LELC is favorable, the most common approach is radical gastrectomy involving an extensive D2 lymph node dissection. Here, we report four cases of EBV-associated early LELC that were treated by an alternative approach, endoscopic submucosal dissection(ESD). The long-term outcome of this procedure is discussed. All patients were treated by ESD en bloc, and all ESD specimens showed tumor-free lateral resection margins. None of the lesions showed lymphovascular invasion. A pathological examination of ESD specimens revealed submucosal invasion of more than 500 μm in all four cases. One patient underwent additional radical surgery post-ESD; no residual tumor or LN metastasis was noted in the surgical specimen. The other three patients did not undergo additional surgery, either because of severe comorbidity or their refusal to undergo operation, but were subjected to medical follow-up. None of the ESD-treated patients reported local recurrence or distant metastases during the 27-32 mo of follow-up after ESD. | Ji Young Lee Kyoung-Mee Kim Byung-Hoon Min Jun Haeng Lee Poong-Lyul Rhee Jae Jun Kim | 2014 | World Journal of Gastroenterology2014,20,5: | 8 |
| 11 | Risk factors of organ failure in cholangitis with bacteriobilia显示文摘AIM: To identify the risk factors for organ failure(OF) in cholangitis with bacteriobilia.METHODS: This study included 182 patients with acute cholangitis who underwent percutaneous transhepatic biliary drainage between January 2005 and April 2013. We conducted a retrospective analysis of comprehensive clinical and laboratory data.RESULTS: There were 24 cases(13.2%) of OF and five deaths(2.7%). Bile culture was positive for microbial growth in 130 out of 138(94.2%) patients. In multivariate analysis of 130 patients with positivebile cultures, significant predictive factors for OF were the presence of extended-spectrum beta-lactamase(ESBL) organisms in blood cultures, pre-existing renal dysfunction, and choledocholithiasis as an etiology, with odds ratios of 15.376, 6.319, and 3.573, respectively. We developed a scoring system with a regression coefficient of each significant variable. The OF score was calculated using the following equation:(2.7 × ESBL organisms in blood cultures) +(1.8 × pre-existing renal dysfunction) +(1.3 × choledocholithiasis). This scoring system for predicting OF was highly specific(99.1%) and had a positive predictive value of 86.2%.CONCLUSION: ESBL organisms in blood cultures, preexisting renal dysfunction, and choledocholithiasis are risk factors for OF in cholangitis with bacteriobilia. The OF scoring system may aid clinicians to identify a poor prognosis group. | Jae Min Lee Sang Hyub Lee Kwang Hyun Chung Jin Myung Park Ban Seok Lee Woo Hyun Paik Joo Kyung Park Ji Kon Ryu Yong-Tae Kim | 2015 | World Journal of Gastroenterology2015,21,24: | 8 |
| 12 | Comparison of postoperative optical quality according to the degree of decentering of V4c implantable collamer lens显示文摘AIM:To evaluate the clinical outcomes of V4 c implantable collamer lens(Hole ICL) implantation with regard to the optical quality assessed according to different degrees of decentering.METHODS:This included 49 eyes that received conventional ICL and 94 eyes that received Hole ICL.The eyes that received Hole ICL were divided into three groups according to the degree of decentering:group 1,central hole within 1 hole diameter(HD) from the pupil center;group 2,central hole within 1 HD to 2 HD;and group 3,central hole within 2 HD to 3 HD.Visual acuity(VA),intraocular pressure(IOP),and spherical equivalent(SE) values were assessed at 1wk,1 and 3mo after surgery.The ocular modulation transfer function,Strehl ratio,objective scattering index,and higher order aberrations(HOAs) were measured for 4-mm pupils at 3mo after surgery.RESULTS:There were no significant differences in VA,IOP,and SE among the conventional and Hole ICL groups.With regard to HOAs,values for coma and spherical aberrations showed no differences.The total HOA and trefoil values were significantly higher in group 2 than in group 1(P=0.02,0.03,respectively).There were no significant differences among groups with regard to other optical quality parameter at 3mo after surgery.CONCLUSION:Our results suggest that Hole ICL implantation provides satisfactory visual quality that is equivalent to that provided by conventional ICL,regardless of the presence of central hole and degree of decentering. | Min Ji Park Hye Min Jeon Kyoung Heon Lee Sang Youp Han | 2017 | International Journal of Ophthalmology(English edition)2017,10,4: | 7 |
| 13 | Clinical and endoscopic characteristics of drug-induced esophagitis显示文摘AIM: To investigate clinical, endoscopic and pathological characteristics of drug-induced esophagitis.METHODS: Data for patients diagnosed with drug-induced esophagitis from April 2002 to May 2013 was reviewed. Patients diagnosed with malignancy, viral or fungal esophagitis were excluded. Clinical, endoscopic and pathological characteristics of patients diagnosed with drug-induced esophagitis were analyzed.RESULTS: Seventy-eight patients were diagnosed with drug-induced esophagitis. Their mean age was 43.9 ± 18.9 years and 35.9% were male. Common symptoms were chest pain(71.8%), odynophagia(38.5%) and dysphagia(29.5%). The endoscopic location was in the middle third of esophagus in 78.2%. Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ulcers.CONCLUSION: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug. Kissing ulcers were observed in 43.6%. | Su Hwan Kim Ji Bong Jeong Ji Won Kim Seong-Joon Koh Byeong Gwan Kim Kook Lae Lee Mee Soo Chang Jong Pil Im Hyoun Woo Kang Cheol Min Shin | 2014 | World Journal of Gastroenterology2014,20,31: | 7 |
| 14 | Clinicopathologic and molecular features associated with patient age in gastric cancer显示文摘AIM: To compare characteristics and prognosis of gastric cancer based on age.METHODS: A retrospective study was conducted on clinical and molecular data from patients(n =1658) with confirmed cases of gastric cancer in Seoul National University Bundang Hospital(Seoul, South Korea) from 2003 to 2010 after exclusion of patients diagnosed with lymphoma, gastrointestinal stromal tumor, and metastatic cancer in the stomach. DNA was isolated from tumor and adjacent normal tissue,and a set of five markers was amplified by polymerase chain reaction to assess microsatellite instability(MSI). MSI was categorized as high, low, or stable if ≥ 2, 1, or 0 markers, respectively, had changed.Immunohistochemistry was performed on tissue sections to detect levels of expression of p53, human epidermal growth factor receptor(HER)-2, and epidermal growth factor receptor. Statistical analysis of clinical and molecular data was performed to assess prognosis based on the stratification of patients by age(≤ 45 and> 45 years).RESULTS: Among the 1658 gastric cancer patients, the number of patients with an age ≤ 45 years was 202(12.2%; 38.9 ± 0.4 years) and the number of patients> 45 years was 1456(87.8%; 64.1 ± 0.3 years).Analyses revealed that females were predominant inthe younger group(P < 0.001). Gastric cancers in the younger patients exhibited more aggressive features and were at a more advanced stage than those in older patients. Precancerous lesions, such as atrophic gastritis and intestinal metaplasia, were observed less frequently in the older than in the younger group(P < 0.001). Molecular characteristics, including overexpression of p53(P < 0.001), overexpression of HER-2(P = 0.006), and MSI(P = 0.006), were less frequent in gastric cancer of younger patients. Cancer related mortality was higher in younger patients(P= 0.048), but this difference was not significant after adjusting for the stage of cancer.CONCLUSION: Gastric cancer is distinguishable between younger and older patients based on both clinicopathologic and molecular features, but stage is the most important predictor of prognosis. | Ji Yeon Seo Eun Hyo Jin Hyun Jin Jo Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim Hyun Chae Jung Dong Ho Lee | 2015 | World Journal of Gastroenterology2015,21,22: | 7 |

| 16 | Safety of endoscopic ultrasound-guided ethanol ablation for pancreatic cystic lesions: A single-center experience of 214 patients显示文摘Background:Endoscopic ultrasound-guided ethanol ablation(EUS-EA)for pancreatic cystic lesions(PCLs)has been used in recent years as a feasible treatment modality for low malignant probability PCLs or patients considered high-risk for surgery.The present study aimed to confirm the safety of EUS-EA and to find predictive factors for adverse event(AE).Methods:A retrospective review was performed from the prospectively maintained database of patients who underwent EUS-EA for PCLs from June 2006 to April 2018 at Seoul National University Hospital.The primary outcomes of the study were the rates of AEs and severe AEs by EUS-EA.The secondary outcome was the predictive factors of AEs including acute pancreatitis and abdominal pain.Results:A total of 214 patients were evaluated and the diagnoses of PCLs according to cystic fluid analysis and clinical features were as follows:serous cystic neoplasm(32.2%),mucinous cystic neoplasm(26.6%),branch duct type intraductal papillary mucinous neoplasm(BD-IPMN)(29.4%),and pseudocyst(11.7%).Three patients(1.4%)experienced severe AEs.Overall,AEs occurred in 71(33.2%)patients.BD-IPMN(OR:2.87;95%CI:1.05–7.84;P=0.040),multilocular cysts(OR:3.59;95%CI:1.09–11.85;P=0.036),suspected ethanol leakage during procedure(OR:10.68;95%CI:1.98–57.53;P=0.006),and sticky cystic fluid(OR:3.83;95%CI:1.20–12.24;P=0.024)were predictive factors for post-procedural acute pancreatitis.PCLs of uncinate process(OR:2.99;95%CI:1.22–7.35;P=0.017)and PCLs with exophytic portion(OR:3.70;95%CI:1.96–7.01;P<0.001)were predictive factors for post-procedural abdominal pain.Conclusions:EUS-EA is a safe procedure with a very low rate of severe AEs.It seems possible to predict the AEs according to the features of the procedure and PCLs. | Jin Ho Choi Sang Hyub Lee Young Hoon Choi Min Su You Bang-Sup Shin Woo Hyun Paik Ji Kon Ryu Yong-Tae Kim | 2019 | Hepatobiliary & Pancreatic Diseases International2019,18,6: | 6 |
| 17 | Ampullary neuroendocrine tumor diagnosed by endoscopic papillectomy in previously confirmed ampullary adenoma显示文摘Ampullary adenoma is a common indication for endoscopic papillectomy. Ampullary neuroendocrine tumor(NET) is a rare disease for which complete surgical resection is the treatment of choice. However, because of the morbidity and mortality associated with surgical resection, endoscopic papillectomy is increasingly used in selected cases of low grade, with no metastasis and no invasion of the pancreatic or bile duct. Also, confirmed and complete endoscopic resection of ampullary NET accompanied by adenoma has not been reported to date. We report herein a rare case of an ampullary NET accompanied with adenoma, which was successfully and completely resected via endoscopic papillectomy. Prior to papillectomy, this case was diagnosed as an ampullary adenoma. | Seoung Ho Lee Tae Hoon Lee Si-Hyong Jang Chi Young Choi Won Myung Lee Ji Hey Min Hyun Deuk Cho Sang-Heum Park | 2016 | World Journal of Gastroenterology2016,22,13: | 6 |
| 18 | How to improve patient satisfaction during midazolam sedation for gastrointestinal endoscopy?显示文摘AIM To determine the procedure-related factors that affect sedation satisfaction and to make a suggestion to improve it.METHODS We prospectively enrolled a total of 456 patients who underwent outpatient endoscopy procedures with midazolam sedation between March 2014 and August 2014. All patients completed both pre- and postendoscopy questionnaires about sedation expectations and satisfaction. RESULTS The study cohort included 167 (36.6%) patients whounderwent esophagogastroduodenoscopy (EGD), 167 (36.6%) who underwent colonoscopy, and 122(26.8%) who underwent a combined procedure (EGD and colonoscopy). Over 80% of all patients were satisfied with sedation using midazolam. In univariate and multivariate analyses, total procedure time in the EGD group, younger age (≤ 50 years), and longer colonoscopy withdrawal time in the colonoscopy group were related to decreased satisfaction with sedation. However, in active monitoring and intervention group, there was no decrease in grade of satisfaction despite longer procedure time due to more procedures during colonoscopy. Younger age (≤ 50 years), longer interprocedure time gap, and colonoscopy withdrawal time were related to decreased satisfaction in the combined EGD and colonoscopy group. CONCLUSION Midazolam is still a safe and effective sedative for gastrointestinal endoscopy. Satisfaction with sedation depends on several factors including age(≤ 50 years) and procedure time duration. To improve patient satisfaction with sedation, active monitoring of sedation status by the endoscopist should be considered for patients who require long procedure time. | Eun Hyo Jin Kyoung Sup Hong Young Lee Ji Yeon Seo Ji Min Choi Jaeyoung Chun Sang Gyun Kim Joo Sung Kim Hyun Chae Jung | 2017 | World Journal of Gastroenterology2017,23,6: | 6 |
| 19 | Detection of early gastric cancer using hydro-stomach CT:Blinded vs unblinded analysis显示文摘AIM:To evaluate the difference in diagnostic performance of hydro-stomach computed tomography(CT) to detect early gastric cancer(EGC) between blinded and unblinded analysis and to assess independent factors affecting visibility of cancer foci.METHODS:Two radiologists initially blinded and then unblinded to gastroscopic and surgical-histological findings independently reviewed hydro-stomach CT images of 110 patients with single EGC.They graded the visibility of cancer foci for each of three gastric segments(upper,middle and lower thirds) using a 4-point scale(1:definitely absent,2:probably absent,3:probably present,and 4:definitely present).The sensitivity and specificity for detecting an EGC were calculated.Intraobserver and interobserver agreements were analyzed.The visibility of an EGC was evaluated with regard to tumor size,invasion depth,gastric segments,histological type and gross morphology using univariate and multivariate analysis.RESULTS:The respective sensitivities and specificities [reviewer 1:blinded,20%(22/110) and 98%(215/220);unblinded,27%(30/110) and 100%(219/220)/reviewer 2:blinded,19%(21/110) and 98%(216/220);unblinded,25%(27/110) and 98%(215/220)] were not significantly different.Although intraobserver agreements were good(weighted κ = 0.677 and 0.666),interobserver agreements were fair(blinded,0.371) or moderate(unblinded,0.558).For both univariate and multivariate analyses,the tumor size and invasion depth were statistically significant factors affecting visibility.CONCLUSION:The diagnostic performance of hydrostomach CT to detect an EGC was not significantly different between blinded and unblinded analysis.The tumor size and invasion depth were independent factors for visibility. | Ki Jeong Park Min Woo Lee Ji Hyun Koo Yulri Park Heejung Kim Dongil Choi Soon Jin Lee | 2011 | World Journal of Gastroenterology2011,17,8: | 6 |
