Latest Advances in Endoscopic Imaging and Therapy—Part I

Dear Colleagues,

Recently, research on narrow-band imaging (NBI) has reported benefits regarding the accuracy and reproducibility of endoscopic diagnosis for gastrointestinal (GI) tumors and premalignant lesions. Available image-enhanced endoscopy (IEE) techniques include blue laser imaging (BLI), linked color imaging (LCI), dual red imaging (DRI), and infra-red imaging (IRI). The latest advances in imaging modalities in GI endoscopy have mainly been associated with the development of artificial intelligence (AI), and computer-aided diagnosis (CAD) is garnering increased investigation. On the other hand, endoscopists should bear in mind that a combination of AI harness power and hyperspectral imaging methods, such as photodynamic diagnosis, is required. Accurate endoscopic diagnosis under IEE magnification or near-focus magnification is effective for discriminating the GI tract tumor margin before endoscopic resection, whilst endocytoscopy and confocal laser endomicroscopy enable the production of real-time in vivo histologic images under ultra-magnification.

Using secure diagnostic modalities, endoscopic submucosal dissection (ESD) for diverse GI tumors could be standardized, and its applications comparting peroral endoscopic tumor resections and en bloc full-layer thickness resection are emerging, requiring high levels of skill and expertise, even for submucosal tumors. Such methods might be supported by advancements in accessary devices like SureClip, S-O Clip, and OTSC systems for suturing.

This Special Issue aims to disseminate knowledge on how endoscopic imaging is being developed to provide readers with a view of the future of diagnostic luminal endoscopy and present the latest advancements in endoluminal therapeutic techniques.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
