| 1 | Characterization of smooth muscle, enteric nerve, interstitial cells of Cajal, and fibroblast-like cells in the gastric musculature of patients with diabetes mellitus显示文摘AIM To investigate histologic abnormalities in the gastric smooth muscle of patients with diabetes mellitus(DM).METHODS Full-thickness gastric specimens were obtained from patients undergoing surgery for gastric cancer. H&E stain and Masson's Trichrome stain were performed to assess the degree of fibrosis. Immunohistochemical staining using various antibodies was also performed [antibodies against protein gene product 9.5(PGP9.5), neuronal nitric oxide synthase(n NOS), vasoactive intestinal peptide(VIP), neurokinin-1(NK1) receptor, c-Kit, and platelet-derived growth factor receptor-alpha,(PDGFRα)]. Immunofluorescent staining and evaluation with confocal microscopy were also conducted.RESULTS Twenty-six controls and 35 diabetic patients(21 shortduration patients and 14 long-duration patients) were included. There were no significant differences in basic demographics between the two groups except in mean body mass index(BMI)(higher in the DM group). Proportions of moderate-to-severe intercellular fibrosis in the muscle layer were significantly higher in the DM group than in the control group(P < 0.01). On immunohistochemical staining, c-Kit- and PDGFRα-positive immunoreactivity were significantly decreased in the DM group compared with the control group(P < 0.05). There were no statistically significant differences in PGP9.5, n NOS, VIP, and neurokinin 1 expression. On immunofluorescent staining, cellularity of interstitial cells of Cajal(ICC) was observed to decrease with increasing duration of DM.CONCLUSION Our study suggests that increased intercellular fibrosis, loss of ICC, and loss of fibroblast-like cells are found in the smooth muscle of DM patients. These abnormalities may contribute to changes in gastric motor activity in patients with DM. | Kyung Sik Park Kwang Bum Cho Il Seon Hwang Jae Hyung Park Byung Ik Jang Kyeong Ok Kim Sung Woo Jeon Eun Soo Kim Chang Sik Park Joong Goo Kwon | 2016 | World Journal of Gastroenterology2016，22，46： | 11 |
| 2 | 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 |
| 3 | Association between Helicobacter pylori status and metachronous gastric cancer after endoscopic resection显示文摘AIM To investigate the effect of Helicobacter pylori(H. pylori) status test and H. pylori eradication on the occurrence of metachronous gastric cancer(MGC) after endoscopic submucosal dissection(ESD) of early gastric cancer(EGC) and risk factors of MGC. METHODS The authors retrospectively reviewed the medical records of 433 patients(441 lesions) who underwent ESD for EGC from January 2005 to January 2015 in Yeungnam University Hospital. Patients were categorized into two groups; the H. pylori tested group(n = 257) and the H. pylori non-tested group(n = 176) based on performance of H. pylori status test after ESD of EGC. The H. pylori tested group was further categorized into three subgroups based on H. pylori status; the H. pylori-eradicated subgroup(n = 120), the H. pylori-persistent subgroup(n = 42), and the H. pylori-negative subgroup(n = 95). Incidences of MGC and risk factors of MGC were identified.RESULTS Median follow-up duration after ESD was 30.00 mo(range, 6-107 mo). Total 15 patients developed MGC during follow-up. MGC developed in 11 patients of the H. pylori tested group(7 in the H. pylori-negative subgroup, 3 in the H. pylori-eradicated subgroup, and 1 in the H. pylori-persistent subgroup) and 4 patients of the H. pylori non-tested group(P > 0.05). The risk factors of MGC were endoscopic mucosal atrophy in the H. pylori tested group and intestinal metaplasia in all patients. CONCLUSION H. pylori eradication and H. pylori status test seems to have no preventive effect on the development of MGC after ESD for EGC. The risk factors of MGC development were endoscopic mucosal atrophy in the H. pylori tested group alone and intestinal metaplasia in all patients. | Sung Bum Kim Si Hyung Lee Seung Il Bae Yo Han Jeong Se Hoon Sohn Kyeong Ok Kim Byung Ik Jang Tae Nyeun Kim | 2016 | World Journal of Gastroenterology2016，22，44： | 8 |
| 4 | Technical issues and new devices of ESD of early gastric cancer显示文摘Endoscopic submucosal dissection(ESD) is a highly refined technique compared to conventional endoscopic mucosal resection.It enables complete resection of early gastric cancer(EGC) which has no possibility of lymph node metastasis.Indication for ESD of EGC generally entails early gastric cancer confined to the mucosa with well differentiated histology,though there are clinically suitable expanded criteria.As ESD requires specific skill and expertise,endoscopists need to be familiarized with basic methods and the use of special devices.The essence of the technique is to dissect the submucosal layer with direct vision and maintain thecutting plane above the underlying proper muscle layer.Although there are some differences in the detailed technical aspect,the cardinal method of ESD is now well established and standardized.Furthermore,research and development of new ESD devices that render more efficient,safe ESD are still in progress to improve the overall result of ESD on early gastric cancer. | Wan Sik Lee Jin Woong Cho Young Dae Kim Kyu Jong Kim Byung Ik Jang | 2011 | World Journal of Gastroenterology2011，17，31： | 8 |
| 5 | Significant risk and associated factors of active tuberculosis infection in Korean patients with inflammatory bowel disease using anti-TNF agents显示文摘AIM:To evaluate the incidence and risk factors of Korean tuberculosis(TB) infection in patients with inflammatory bowel disease(IBD) undergoing anti-TNF treatment.METHODS:The data of IBD patients treated with anti-TNFs in 13 tertiary referral hospitals located in the southeastern region of Korea were collected retrospectively.They failed to show response or were intolerant to conventional treatments,including steroids or immunomodulators.Screening measures for latent TB infection(LTBI)and the incidence and risk factors ofactive TB infection after treatment with anti-TNFs were identified.RESULTS:Overall,376 IBD patients treated with antiTNF agents were recruited(male 255,mean age of anti-TNF therapy 32.5±13.0 years);277 had Crohn’s disease,99 had ulcerative colitis,294 used infliximab,and 82 used adalimumab.Before anti-TNF treatment,screening tests for LTBI including an interferon gamma release assay or a tuberculin skin test were performed in 82.2%of patients.Thirty patients(8%)had LTBI.Sixteen cases of active TB infection including one TB-related mortality occurred during 801 personyears(PY)follow-up(1997.4 cases per 100000 PY)after anti-TNF treatment.LTBI(OR=5.76,95%CI:1.57-21.20,P=0.008)and WBC count<5000 mm3(OR=4.5,95%CI:1.51-13.44,P=0.007)during follow-up were identified as independently associated risk factors.CONCLUSION:Anti-TNFs significantly increase the risk of TB infection in Korean patients with IBD.The considerable burden of TB and marked immunosuppression might be attributed to this risk. | Eun Soo Kim Geun Am Song Kwang Bum Cho Kyung Sik Park Kyeong Ok Kim Byung Ik Jang Eun Young Kim Seong Woo Jeon Hyun Seok Lee Chang Heon Yang Yong Kook Lee Dong Wook Lee Sung Kook Kim Tae Oh Kim Jonghun Lee Hyung Wook Kim Sam Ryong Jee Seun Ja Park Hyun Jin Kim | 2015 | World Journal of Gastroenterology2015，21，11： | 5 |

| 18 | Efficacy of 0.5-L vs 1-L polyethylene glycol containing ascorbic acid as additional colon cleansing methods for inadequate bowel preparation as expected by last stool examination before colonoscopy显示文摘BACKGROUND No consensus has been reached in patients suspected of having inadequate bowel preparation regarding optimal salvage methods, which negatively affects the efficacy and quality of colonoscopy. The most ideal and reasonable rescue option involves early suspicion and identification of patients with inadequate preparation before sedation, additional oral ingestion of a suitable preparation formulation, and same-day colonoscopy.AIM To compare 0.5-L and 1-L polyethylene glycol containing ascorbic acid(PEG +Asc) as additional bowel cleansing methods after a 2-L split-dose PEG + Asc regimen in patients with expected inadequate bowel preparation before colonoscopy.METHODS Individuals with expected inadequate bowel preparation based on last stool form, such as turbid liquid, particulate liquid, or liquid with small amounts of feces, were randomized to either a 0.5-L PEG + Asc group or a 1-L PEG + Asc group. The primary endpoint was bowel preparation as assessed using the Aronchick bowel preparation scale(ABPS) and Boston bowel preparation scale(BBPS) scores. The secondary endpoints were cecal intubation time, withdrawal time, polyp detection rate(PDR), adenoma detection rate(ADR), individual compliance with additional PEG + Asc, and patient satisfaction.RESULTS Initially, 98 patients were included, but 8 were later excluded due to withdrawal of consent to participate in the study. Adequate bowel preparation(as assessed by ABPS) was observed in 80.9%(38/47) of subjects in the 0.5-L group and in88.4%(38/43) of subjects in the 1-L group(P = 0.617). Mean total BBPS was 6.7 points in the 0.5-L group and 7.0 points in the 1-L group(P = 0.458). ADRs and PDRs were similar in the two groups, and cecal intubation and withdrawal times were not significantly different. However, mean patient satisfaction score was significantly higher in the 0.5-L group(P = 0.041).CONCLUSION The bowel cleaning efficacy of additional 0.5-L PEG + Asc was not inferior to that of 1-L PEG + Asc. Additional 0.5-L PEG + Asc is worthwhile when inadequate bowel preparation is expected before colonoscopy. | Joon Hyun Cho Eun Joo Goo Kyeong Ok Kim Si Hyung Lee Byung Ik Jang Tae Nyeun Kim | 2019 | World Journal of Clinical Cases2019，7，1： | 1 |
