Colonoscopy attachments for the detection of precancerous lesions during colonoscopy:A review of the literature

World Journal of Gastroenterology 2018年第37期24卷 4243-4253页

作者： Paraskevas Gkolfakis Georgios Tziatzios eleftherios Spartalis Ioannis S Papanikolaou Konstantinos Triantafyllou Hepatogastroenterology Unit Second Department of Internal Medicine-PropaedeuticResearch Institute and Diabetes CenterMedical SchoolNational and Kapodistrian University of Athens''Attikon”University General HospitalAthens 12462Greece Laboratory of Experimental Surgery and Surgical Research National and Kapodistrian University of AthensAthens 12462Greece

Although colonoscopy has been proven effective in reducing the incidence of colorectal cancer through the detection and removal of precancerous lesions, it remains an imperfect examination, as it can fail in detecting up to almost one fourth of existing adenomas. Among reasons accounting for such failures, is the inability to meticulously visualize the colonic mucosa located either proximal to haustral folds or anatomic curves, including the hepatic and splenic flexures. In order to overcome these limitations, various colonoscope attachments aiming to improve mucosal visualization have been developed. All of them-transparent cap, Endocuff, Endocuff Vision and Endorings-are simply mounted onto the distal tip of the scope. In this review article, we introduce the rationale of their development, present their mode of action and discuss in detail the effect of their implementation in the detection of lesions during colonoscopy.

Background:MNREAD is an advanced near-vision acuity chart that has already been translated and validated in Greek *** that no validated Greek digital near-vision test exists,our primary objective was to develop and validate a digital near-vision reading test based on the fundamental properties of the Greek printed MNREAD(MNREAD-GR).Methods:This is a prospective,comparative study.A digital near-vision chart was developed(Democritus Digital Acuity Reading Test-DDART)with text size calibration,audio recording for automatic reading timing,as well as automatic calculation of reading acuity(RA),maximum reading speed(MRS),critical print size(CPS)and reading accessibility index(ACC).Normal and low vision subjects participated in the validation process,responding to MNREAD-GR and DDART at the same day,at a 40 cm viewing *** in all parameters between the charts were compared with t-test and intraclass correlation coefficients(ICCs).Within 15 days,all participants responded again to DDART in a different set of sentences to assess its test-retest ***:One hundred patients(normal vision group-NVG:70 patients;low vision group-LVG:30 patients)responded to both reading ***-significant differences were detected for all parameters between DDART and MNREAD-GR except for MRS and ACC that were significantly higher in MNREAD-GR in NVG(p<0.01).NVG participants demonstrated sufficient ICCs that ranged from 0.854 to 0.963,while LVG demonstrated ICCs for RA,ACC,MRS and CPS equal to 0.986,0.894,0.794 and 0.723,*** parameters calculated with DDART demonstrated excellent test-retest reliability(ICCs:0.903-0.956).Conclusions:The proposed reading test presented comparable validity and repeatability to MNREAD-GR suggesting that it can be used both in normal and low vision Greek patients.

Vision and Geolocation Data Combination for Precise Human Detection and Tracking in Search and Rescue Operations

引用

International Journal of Intelligence Science 2020年第3期10卷 41-64页

作者： Lygouras eleftherios Department of Production and Management Engineering Democritus University of Thrace Xanthi Greece

In this paper, a study and evaluation of the combination of GPS/GNSS techniques and advanced image processing algorithms for distressed human detection, positioning and tracking, from a fully autonomous Unmanned Aerial Vehicle (UAV)-based rescue support system, are presented. In particular, the issue of human detection both on terrestrial and marine environment under several illumination and background conditions, as the human silhouette in water differs significantly from a terrestrial one, is addressed. A robust approach, including an adaptive distressed human detection algorithm running every N input image frames combined with a much faster tracking algorithm, is proposed. Real time or near-real-time distressed human detection rates achieved, using a single, low cost day/night NIR camera mounted onboard a fully autonomous UAV for Search and Rescue (SAR) operations. Moreover, the generation of our own dataset, for the image processing algorithms training is also presented. Details about both hardware and software configuration as well as the assessment of the proposed approach performance are fully discussed. Last, a comparison of the proposed approach to other human detection methods used in the literature is presented.

Conduit necrosis following esophagectomy: An up-to-date literature review

World Journal of Gastrointestinal Surgery 2019年第3期11卷 155-168页

Esophageal conduit ischaemia and necrosis is an uncommon but devastating complication of esophagectomy and remains one of the most challenging issues in surgical practice. The incidence, time interval to develop symptoms, and clinical presentation are highly variable with no predictable pattern. Evidence comes from case reports and case series rather than randomized controlled *** describe the issues surrounding conduit necrosis affecting the stomach,jejunum and colon as an esophageal replacement and the advantages,disadvantages and challenges of each type of reconstruction. Diagnosis is challenging for the most experienced surgeon. Upper gastrointestinal endoscopy and computed tomography thorax with both oral and intravenous contrast is the gold standard. Management, either conservative or interventional is also a difficult decision. Management options include conservative treatment and more aggressive treatments such as stent insertion, surgical debridement and repair of the esophagus using jejunum, colon or a musculocutaneous flap. In spite of recent advances in surgical techniques, there is no reliable strategy to manage esophageal conduit necrosis. Our review covers the pathophysiology and clinical significance of esophageal necrosis while highlighting current techniques of prevention, diagnosis and treatment of this life-threatening condition.
