Here we address interventional EUS and its role in pancreatic cyst ablation as well as EUS-guided solid tumor ablation and treatment. EUS-guided pancreatic cyst chemoablation has been shown to be an effective, safe, and durable option for the treatment of appropriately selected, mucinous-type, pancreatic cysts when approached as part of a high volume multidisciplinary program. In the treatment of solid pancreatic lesions, multiple endoscopic therapies have shown promise with most attention focused on the treatment of pancreatic neuroendocrine tumors. More advanced tumors and malignancies have also been treated with encouraging, but limited, results, and this area of interventional EUS is in need of prospective studies with standardized definitions of safety and treatment responses as development continues.</div></div>","PeriodicalId":36169,"journal":{"name":"Techniques and Innovations in Gastrointestinal Endoscopy","volume":"26 4","pages":"Pages 335-346"},"PeriodicalIF":1.2,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CRC screening saves lives, but reach across the population, including across age and sociodemographic groups, is highly variable. CRC screening participation in the United States remains at under 60% and has been stagnant over time. Lower screening participation is observed for individuals of younger age; of American Indian/Alaska Native, Asian, and Hispanic backgrounds; with Medicaid insurance; and with recent immigration. Addressing suboptimal reach is increasingly important due to changing CRC epidemiology and US population structure. Recent trends demonstrate increases in early (&lt;50 years) and middle age (50-60 years) onset of CRC and nonlocalized-stage CRC, as well as persistent inequities in CRC outcomes among multiple racial/ethnic groups. These trends exist in a context where the US population is increasingly composed of individuals from diverse backgrounds associated with lower screening rates and higher rates of adverse CRC outcomes. Screening reach can be optimized by building on successes of previous impactful policies, implementing evidence-based interventions for screening, and developing novel strategies that address challenges at patient, clinician, healthcare system, and policy levels. Gastroenterologists, other clinicians, and public health advocates have a major role in leading positive change at each of these levels. Overall, the need to optimize the reach of CRC screening represents a pressing opportunity for improving health equity across all populations in the United States.</p></div>","PeriodicalId":36169,"journal":{"name":"Techniques and Innovations in Gastrointestinal Endoscopy","volume":"26 2","pages":"Pages 153-166"},"PeriodicalIF":2.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590030724000175/pdfft?md5=a559ef75ac2e110d0900ec33d59ea3b9&pid=1-s2.0-S2590030724000175-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140272497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological and clinical study evidence has suggested that early detection and treatment of BE-related neoplasia is associated with improved survival, suggesting that screening for this condition could impact EAC survival. Over the past few decades, there have been accelerated advances in the field of BE and EAC, particularly in the emergence of non-endoscopic cell-collection devices that could be used for screening. In this review, we critically discuss the concept of screening BE and EAC, as well as identifying the target population who should be screened. We then review the evidence for various cell-collection devices that could be used for screening in the office-based setting, such as screenig using prediction models, transnasal endoscopy (TNE), Cytosponge and biomarker Trefoil-factor 3 (TFF3), EsophaCap and methylated DNA markers (MDMs), and the balloon-based EsoCheck and MDMs. We also discuss other novel technologies, such as volatile organic compound detection using the electric nose and technologies using optical coherence tomography. These promising technologies have paved the way for the potential introduction of a screening program for BE and EAC, with the hope that this could lead to improved outcomes among patients who suffer from this unfortunate disease.</p></div>","PeriodicalId":36169,"journal":{"name":"Techniques and Innovations in Gastrointestinal Endoscopy","volume":"25 2","pages":"Pages 146-156"},"PeriodicalIF":2.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49765364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
