| 1 | Improved bowel preparation increases polyp detection and unmasks significant polyp miss rate显示文摘AIM: To retrospectively compare previous-day vs splitdose preparation in terms of bowel cleanliness and polyp detection in patients referred for polypectomy. METHODS: Fifty patients underwent two colonoscopies: one diagnostic in a private clinic and a second for polypectomy in a University Hospital. The latter procedures were performed within 12 wk of the index ones. Examinations were accomplished by two experienced endoscopists, different in each facility. Twenty-seven patients underwent screening/surveillance colonoscopy, while the rest were symptomatic. Previous day bowel preparation was utilized initially and splitdose for polypectomy. Colon cleansing was evaluated using the Aronchick scale. We measured the number of detected polyps, and the polyp miss rates per-polyp.RESULTS: Excellent/good preparation was reported in 38 cases with previous-day preparation(76%) vs 46 with split-dose(92%), respectively(P = 0.03). One hundred and twenty-six polyps were detected initially and 169 subsequently(P < 0.0001); 88 vs 126 polyps were diminutive(P < 0.0001), 25 vs 29 small(P = 0.048) and 13 vs 14 equal or larger than 10 mm. The miss rates for total, diminutive, small and large polyps were 25.4%, 30.1%, 13.7% and 6.6%, respectively. Multivariate analysis revealed that split-dose preparation was significantly associated(OR, P) with increased number of polyps detected overall(0.869, P < 0.001), in the right(0.418, P = 0.008) and in the left colon(0.452, P = 0.02). CONCLUSION: Split-dose preparation improved colon cleansing, enhanced polyp detection and unmasked significant polyp miss rates. | Ioannis S Papanikolaou Athanasios D Sioulas Nektarios Magdalinos Iosif Beintaris Lazaros-Dimitrios Lazaridis Dimitrios Polymeros Chrysoula Malli George D Dimitriadis Konstantinos Triantafyllou | 2015 | World Journal of Clinical Cases2015，3，10： | 4 |

| 4 | 屏蔽的 colorectal 癌症上的希腊医学院的学生的了解和态度显示文摘 AIM: To prospectively assess the knowledge and attitudes of medical students (MS), as tomorrow’s physicians, about colorectal cancer (CRC) and its screening modalities.METHODS: Three hundred fourth year MS of the University of Athens were enrolled in this survey. Their selection was random, based on student identification card number. All participants completed an anonymous written questionnaire over a 4 month period. The questionnaire was divided into 4 sections and included queries about CRC-related symptoms, screening with colonoscopy and MS awareness and attitudes in this field. Following collection and analysis of the data, the results are presented as percentages of answers for each separate question. RESULTS: Two hundred and sixty-five students an-swered the questionnaire over a 4 mo period. Interestingly, only 69% of the study population considered CRC to be a high-risk condition for public health. However, the vast majority of participants identified CRC-related symptoms and acknowledged its screening to be of great value in reducing CRC incidence and mortality. A very small proportion (38%) had received information material regarding CRC screening (either during their medical training or as a part of information provided to the general public) and only 60% of the participants declared willingness to receive further information. Regarding colonoscopy, 85% would prefer an alternative to colonoscopy methods for CRC screening. Moreover, 53% considered it to be a painful method and 68% would appreciate more information about the examination.CONCLUSION: MS in Greece need to be better informed about CRC screening and screening colonoscopy. | Ioannis S Papanikolaou Athanasios D Sioulas Stylianos Kalimeris Persephone Papatheodosiou Ioannis Karabinis Olga Agelopoulou Iosif Beintaris Dimitrios Polymeros George Dimitriadis Konstantinos Triantafyllou | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，11： | 1 |
| 5 | Academic hospital staff compliance with a fecal immunochemical test-based colorectal cancer screening program显示文摘AIM: To measure the compliance of an Academic Hospital staff with a colorectal cancer(CRC) screening program using fecal immunochemical test(FIT).METHODS: All employees of 'Attikon' University General Hospital aged over 50 years were thoroughly informed by a team of physicians and medical students about the study aims and they were invited to undergo CRC screening using two rounds of FIT(DyoniFOB~ Combo H, DyonMed SA, Athens, Greece). The tests were provided for free and subjects tested positive were subsequently referred for colonoscopy. One year after completing the two rounds, participants were asked to be re-screened by means of the same test.RESULTS: Among our target population consisted of 211 employees, 59(27.9%) consented to participate, but only 41(19.4%) and 24(11.4%) completed the first and the second FIT round, respectively. Female gender was significantly associated with higher initial participation(P = 0.005) and test completion- first and second round-(P = 0.004 and P = 0.05) rates, respectively. Phy sician’s(13.5% vs 70.2%, P < 0.0001) participation and test completion rates(7.5% vs 57.6%, P < 0.0001 for the first and 2.3% vs 34%, P < 0.0001 for the second round) were significantly lower compared to those of the administrative/technical staff. Similarly, nurses participated(25.8% vs 70.2%, P = 0.0002) and completed the first test round(19.3% vs 57.6%, P = 0.004) in a significant lower rate than the administrative/technical staff. One test proved false positive. No participant repeated the test one year later.CONCLUSION: Despite the well-organized, guided and supervised provision of the service, the compliance of the Academic Hospital personnel with a FIT-based CRC screening program was suboptimal, especially among physicians. | Georgia Vlachonikolou Paraskevas Gkolfakis Athanasios D Sioulas Ioannis S Papanikolaou Anastasia Melissaratou Giannis-Aimant Moustafa Eleni Xanthopoulou Gerasimos Tsilimidos Ioanna Tsironi Paraskevas Filippidis Chrysoula Malli George D Dimitriadis Konstantinos Triantafyllou | 2016 | World Journal of Gastrointestinal Oncology2016，8，8： | 0 |
