Advances in Gastrointestinal Endoscopy

Dear Colleagues,

The most significant advances in diagnostic gastrointestinal (GI) endoscopy have been image-enhanced endoscopy and endocytoscopy/endomicroscopy, which require specialized expertise. Looking ahead, the future of diagnostic endoscopy may shift towards artificial intelligence, potentially reducing human error and optimizing efficiency.

GI endoscopy has evolved into an effective therapeutic tool. Two decades ago, endoscopic submucosal dissection (ESD) broke the size limitations of endoscopic resection (ER). Since then, advanced ER technology has developed rapidly. These advancements include the development of traction methods during ESD and post-procedure wound closure techniques, enhancing the safety and efficacy of ESD. Additionally, robot-assisted ESD is under development, and the therapeutic applications of ESD have expanded to third-/fourth-space endoscopy and full-thickness resection.

Endoscopic ultrasound's (EUS) utility is expanding rapidly with accessory and instrumentation advancements. Innovations like EUS-guided gastroenterostomy and gallbladder drainage complement EUS-guided core biopsy. In cases where conventional ERCP fails, EUS-guided pancreaticobiliary drainage provides an alternative to traditional methods.

Challenges remain in some areas, such as cholangioscopy, gastroesophageal reflux management, and bariatric and metabolic endoscopy.

Mastering these procedures requires cutting-edge technology and significant educational investment. Certain devices and techniques may require further validation through research for efficacy and safety. With these considerations, we propose the Special Issue titled "Advances in Gastrointestinal Endoscopy." It will deepen our collective understanding of and improve treatment outcomes in this evolving field.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diagnostics 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.
