| 1 | Solutions for submucosal injection: What to choose and how to do it显示文摘During the past decades, endoscopic resection techniques have gradually improved and gained more importance for the management of premalignant lesions and early cancers. These endoscopic resection techniques can be divided in 3 major groups: snare polipectomy, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD). The use of submucosal injection is essential for the majority of EMR techniques and is an integral part of ESD,whereas during polipectomy it is not crucial in most cases except to prevent bleeding in large polyps and/or those with large stalks as an alternative to mechanical methods. Injection provides a lifting up effect of the lesion separating it from the muscular layer, thereby reducing thermal injury and the risk of perforation and bleeding while also facilitating en-bloc resection by improving technical feasibility. With this work, we aim to review the most common endoscopic resection techniques and the importance of submucosal injection in each one of them. For that, we present some of the most commonly used submucosal injection solutions, taking into account their advantages and disadvantages. We also discuss, based on current recommendations and our own experience, how and when to preform submucosal injection, depending on lesions features and endoscopic resection technique that′s being used, to assure complete resection and to prevent associated adverse events. Finally, we also present and discuss some new proposed submucosal injection solutions,endoscopic resection techniques and devices that may have a major impact on the future of therapeutic endoscopy. | Rui Castro Diogo Libanio Inês Pita Mário Dinis-Ribeiro | 2019 | World Journal of Gastroenterology2019，25，7： | 13 |
| 2 | Single-lung transplantation in emphysema:Retrospective study analyzing survival and waiting list mortality显示文摘AIM: To performed remains a subject of debate and is the principal aim of the study. METHODS: This retrospective analysis included 73 patients with emphysema(2000-2012). The outcomes of patients undergoing single-lung transplantation(SL)(n = 40) or double-lung transplant(DL)(n = 33) were compared in a Cox multivariate analysis to study the impact of the technique, postoperative complications and acute and chronic rejection on survival rates. Patients were selected for inclusion in the waiting list according to the International Society of Heart Lung Transplantation criteria. Pre and postoperative rehabilitation and prophylaxis, surgical technique and immunosuppressive treatment were similar in every patients. Lung transplantation waiting list information on a national level and retrospective data on emphysema patient survival transplanted in Spain during the study period, was obtained from the lung transplantation registry managed by the National Transplant Organization(ONT). RESULTS: Both groups were comparable in terms of gender and clinical characteristics. We found significant differences in the mean age between the groups, the DL patients being younger as expected from the inclusion criteria. Perioperative complications occurred in 27.6% SL vs 54% DL(P = 0.032). Excluding perioperative mortality, median survival was 65.3 mo for SL and 59.4 mo for DL(P = 0.96). Bronchiolitis obliterans and overall 5-year survival were similar in both groups. Bacterialrespiratory infection, cytomegalovirus and fungal infection rates were higher but not significant in SL. No differences were found between type of transplant and survival(P = 0.48). To support our results, national data on all patients with emphysema in waiting list were obtained(n = 1001). Mortality on the waiting list was 2.4% for SL vs 6.2% for DL. There was no difference in 5 year survival between 235 SL and 430 DL patients transplanted(P = 0.875).CONCLUSION: Our results suggest that SL transplantation in emphysema produce similar survival than DL with less postoperative complication and significant lower mortality in waiting list. | José M Borro María Delgado Elisabeth Coll Salvador Pita | 2016 | World Journal of Transplantation2016，6，2： | 6 |
| 3 | Robust Face Recognition via Low-rank Sparse Representation-based Classification显示文摘Face recognition has attracted great interest due to its importance in many real-world applications. In this paper,we present a novel low-rank sparse representation-based classification(LRSRC) method for robust face recognition. Given a set of test samples, LRSRC seeks the lowest-rank and sparsest representation matrix over all training samples. Since low-rank model can reveal the subspace structures of data while sparsity helps to recognize the data class, the obtained test sample representations are both representative and discriminative. Using the representation vector of a test sample, LRSRC classifies the test sample into the class which generates minimal reconstruction error. Experimental results on several face image databases show the effectiveness and robustness of LRSRC in face image recognition. | Hai-Shun Du Qing-Pu Hu Dian-Feng Qiao Ioannis Pitas | 2015 | International Journal of Automation and computing2015，12，6： | 2 |
