Computer aided diagnosis - detection (CADe) systems have shown notable success in increasing ADR. Recent meta-analyses of RCTs have demonstrated that patients undergoing colonoscopy with CADe assistance had a higher ADR compared with conventional methods. Similarly, computer aided diagnosis - characterization (CADx) systems have proven effective in distinguishing between adenomatous and nonadenomatous polyps, enhancing diagnostic confidence and supporting cost-saving measures like the resect-and-discard strategy. Despite the high performance of these systems, the variability in real-world adoption highlights the importance of integrating artificial intelligence as an assistive tool rather than a replacement for human expertise.Summary: Artificial intelligence integration in colonoscopy, through CADe and CADx systems, marks a significant advancement in gastroenterology. These systems enhance lesion detection and characterization, leading to improved diagnostic accuracy, training outcomes, and clinical workflow efficiency. While artificial intelligence offers substantial benefits, the optimal approach involves using artificial intelligence to augment the expertise of endoscopists, ensuring that clinical decisions remain under human oversight.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":" ","pages":"3-8"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142559300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this article is to critically review recent advances in mechanistic understanding of barrier regulation and the evidence for and against contributions of intestinal barrier loss to disease pathogenesis.Recent findings: It is now recognized that intestinal permeability reflects the combined effects of two distinct routes across tight junctions, which form selectively permeable seals between adjacent epithelial cells, and mucosal damage that leads to nonselective barrier loss. These are referred to as pore and leak pathways across the tight junction and an unrestricted pathway at sites of damage. Despite advances in phenotypic and mechanistic characterization of three distinct permeability pathways, development of experimental agents that specifically target these pathways, and remarkable efficacy in preclinical models, pathway-targeted therapies have not been tested in human subjects.Summary: After decades of speculation, therapeutic interventions that target the intestinal barrier are nearly within reach. More widespread use of available tools and development of new tools that discriminate between pore, leak, and unrestricted pathway permeabilities and underlying regulatory mechanisms will be essential to understanding the local and systemic consequences of intestinal barrier loss.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":" ","pages":"46-53"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11620928/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142669730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because nutrition is a major driver of gut microbiota diversity and function, here we explore the current evidence on the potential of diets in alleviate the deleterious effects of antibiotics consumed during infections.Recent findings: Beneficial nutrients can enhance the symbiotic effect of the gut microbiota with the host, supporting anti-inflammatory responses and maintaining tight junction integrity. Short-chain fatty acids have been shown to positively affect the immune response, reducing the severity of C. difficile infection, whereas high-fibre diets have been shown to promote faster recovery of the gut microbiota after antibiotic therapy.Summary: The role of nutrition during infection is gaining momentum, with key findings exploring the effect of some nutrients in limiting the severity of infections and helping the microbiota recover from antibiotic-induced dysbiosis. Although this field is in its infancy, these findings open the possibility of personalised nutrition as a way of restoring microbiome diversity.

We will focus on recently developed endoscopic techniques and technologies that obviate morbid emergency surgery (the standard management approach in years past).Recent findings: Colonic perforations are rare but potentially fatal complications of both diagnostic and therapeutic colonoscopy resulting in death in approximately 5% of cases with the mortality increasing with delay in diagnosis and treatment. As novel endoscopic techniques and tools have flourished in recent years, our approach to management of these perforations has evolved. With the availability of newer tools such as over the scope clips, enhanced through the scope clips and novel endoscopic suturing devices, colonic perforations can be managed effectively in many or most patients without the morbidity of surgical interventions.Summary: With expanding use of colonoscopy, inadvertent outcomes such as perforations are bound to increase as well. Early diagnosis permits minimally invasive, nonsurgical, endoscopic management in most cases if the expertise and tools are available. Centers with high colonoscopy volumes including therapeutic procedures would be well served to invest in the requisite technologies and expertise.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":" ","pages":"29-37"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142734374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, given the intra and interindividual variability in the gastrointestinal tract of both healthy and diseased states, various systems have shown inconsistencies in targeted drug release to the colon. Recent breakthroughs have led to systems that incorporate multiple independent trigger mechanisms, ensuring drug release even if one mechanism fails due to physiological variability. Such advanced platforms have bolstered the development of oral biologics delivery, an especially promising direction given the lack of commercially available oral antibody medications for IBD. These concepts can be further enhanced by employing 3D printing which enables the personalisation of medicines.Summary: Leveraging these novel technologies can accurately deliver therapeutics to the colon, allowing for treatments beyond gastrointestinal tract diseases. To realize the full potential of colonic drug delivery, it is paramount that research focuses on the clinical translatability and scalability of novel concepts.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":"41 1","pages":"9-15"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11623378/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lumen-opposing metal stents have emerged as a reliable solution for managing gastrojejunal strictures following Roux-en-Y gastric bypass, whether with or without associated leaks. Additionally, they serve as a conduit for performing endoscopic retrograde cholangiopancreatography (ERCP) post-RYGB via EUS-directed ERCP (EDGE). Gastric peroral endoscopic myotomy, originally designed for gastroparesis, has demonstrated effectiveness in treating postgastric sleeve stenosis, particularly the challenging helical stenosis cases. Furthermore, innovative endoscopic antireflux techniques are showing encouraging outcomes in addressing gastroesophageal reflux disease (GERD) following sleeve gastrectomy. Additionally, several modifications have been proposed to enhance the efficacy of transoral outlet reduction (TORe), originally developed to treat weight regain due to gastrojejunal anastomotic issues post-RYGB.Summary: Endoscopic management of bariatric surgery complications is continuously evolving. The development of new techniques and devices allows endoscopists to provide novel, minimally invasive alternatives that were not possible in the near past. Many techniques, however, are limited to expert centers because they are technically demanding, and specialized training in bariatric endoscopy is still required.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":" ","pages":"449-456"},"PeriodicalIF":2.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141428201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
