Usefulness of magnifying endoscopy in post-endoscopic resection scar for early gastric neoplasm:A prospective short-term follow-up endoscopy study

引用

World Journal of Gastroenterology 2009年第3期15卷 349-355页

作者： Tae Hoon Lee Il-Kwun Chung Ji-Young Park Chang kyun Lee Suck-Ho Lee Hong Soo kim Sang-Heum Park Sun-Joo kim Hyun-Deuk Cho Young Hwangbo Division of Gastroenterology Department of Internal MedicineSoonchunhyang University College of MedicineCheonan Hospital23-20 Bongmyung-dongCheonan330-721South Korea Department of Pathology Soonchunhyang University College of MedicineCheonan Hospital23-20 Bongmyung-dongCheonan330-721South Korea Department of Preventive Medicine Soonchunhyang University College of MedicineCheonan Hospital23-20 Bongmyung-dongCheonan330-721South Korea

AIM： To investigate the relationship between postendoscopic resection （ER） scars on magnifying endoscopy （ME） and the pathological diagnosis in order to validate the clinical significance of ME. METHODS： From January, 2007 to June, 2008, 124 patients with 129 post-ER scar lesions were enrolled. Mucosal pit patterns on ME were compared with conventional endoscopy （CE） findings and histological results obtained from targeted biopsies. RESULTS： CE findings showed nodular scars （53/129）, erythematous scars （85/129）, and ulcerative scars （4/129）. The post-ER scars were classified into four pit patterns of sulci and ridges on ME：（ Ⅰ ） 47 round; （Ⅱ） 54 short rod or tubular; （Ⅲ） 19 branched or gyrus-like;and （Ⅳ） 9 destroyed pits. Sensitivity and specificity were 88.9% and 62.5%, respectively, by the presence of nodularity on CE. Erythematous lesions were high sensitivity （100%）, but specificity was as low as 36.7%. The range of the positive predictive va ue （PPV） on CE was as low as 10.6%-25%. Nine type N pit patterns were diagnosed as tumor lesions, and 120 cases of type Ⅰ-Ⅲ pit patterns revealed non-neoplastic lesions. Thus, the sensitivity, specificity, and the PPV of ME were 100%. CONCLUSION： ME findings can detect the presence of tumor in post-ER scar lesions, and make evident the biopsy target site in short-term follow-up. Further large-scale and long-term studies are needed to determine whether ME can replace endoscopic biopsy.

Biodegradable metals as electrodes, interconnectors, and device conductors are essential components in the emergence of transient electronics, either for passive implants or active electronic devices, especially in the fields of biomedical electronics. Magnesium and its alloys are strong candidates for biodegradable and implantable conducting materials because of their high conductivity and biocompatibility, in addition to their well-understood dissolution behavior. One critical drawback of Mg and its alloys is their considerably high dissolution rates originating from their low anodic potential, which disturbs the compatibility to biomedical applications. Herein, we introduce a single-phase thin film of a Mg-Zn binary alloy formed by sputtering, which enhances the corrosion resistance of the device electrode, and verify its applicability in biodegradable electronics. The formation of a homogeneous solid solution of single-phase Mg-3Zn was confirmed through X-ray diffraction and transmission electron microscopy. In addition, the dissolution behavior and chemistry was also investigated in various biological fluids by considering the effect of different ion species. Micro-tensile tests showed that the Mg-3Zn alloy electrode exhibited an enhanced yield strain and elongation in relation to a pure Mg electrode. Cell viability test revealed the high biocompatibility rate of the Mg-3Zn binary alloy thin film. Finally, the fabrication of a wireless heater demonstrated the integrability of biodegradable electrodes and highlighted the ability to prolong the lifecycle of thermotherapy-relevant electronics by enhancing the dissolution resistance of the Mg alloy.

AIM: To compare the risk of developing advanced colorectal neoplasm(ACRN) according to age in ***: A total of 70428 Koreans from an occupational cohort who underwent a colonoscopy between 2003 and 2012 at Kangbuk Samsung Hospital were retrospectively selected. We evaluated and compared odds ratios(OR) for ACRN between the young-adults(YA < 50 years) and in the older-adults(OA ≥ 50 years). ACRN was defined as an adenoma ≥ 10 mm in diameter, adenoma with any component of villous histology, high-grade dysplasia, or invasive ***: In the YA group, age(OR = 1.08, 95%CI: 1.06-1.09), male sex(OR = 1.26, 95%CI: 1.02-1.55), current smoking(OR = 1.37, 95%CI: 1.15-1.63), family history of colorectal cancer(OR = 1.46, 95%CI: 1.01-2.10), diabetes mellitus related factors(OR = 1.27, 95%CI: 1.06-1.54), obesity(OR = 1.23, 95%CI: 1.03-1.47), CEA(OR = 1.04, 95%CI: 1.01-1.09) and low-density lipoprotein-cholesterol(OR = 1.01, 95%CI: 1.01-1.02) were related with an increased risk of ACRN. However, age(OR = 1.08, 95%CI: 1.06-1.09), male sex(OR = 2.12, 95%CI: 1.68-2.68), current smoking(OR = 1.38, 95%CI: 1.12-1.71), obesity(OR = 1.34, 95%CI: 1.09-1.65) and CEA(OR = 1.05, 95%CI: 1.01-1.09) also increased the risk of ACRN in the OA ***: The risks of ACRN differed based on age group. Different colonoscopic screening strategies are appropriate for particular subjects with risk factors for ACRN, even in subjects younger than 50 years.
